The principle of operation of the device

When the tap at the point of water consumption is opened, the pressure in the pipe begins to decrease rapidly. In this case, the unit immediately turns on and, when the minimum pressure is reached, activates the electric pump. The appliance pumps water until the pressure equalizes again (when the tap closes). After the tap is closed, the device works for another 5-20 seconds, continuing to pump water into the line. Such a measure is a precaution in case the pressure in the system drops below normal and the device is not able to track the pressure level.

Automation Gileks (block) for the pump: adjustment

Automation mechanisms for the pump are used to ensure autonomous operation of devices with the setting of a suitable mode. In addition, high-quality automation protects the pumps from dry running and saves energy consumption. This approach allows you to extend the life of expensive pumping equipment.

A feature of automation from the Gileks company is the ability to use devices both with branded models and with devices from other manufacturers. In addition, inexpensive equipment has a number of other useful properties.

Features of the company control unit

The main element of automation of the company's pumping process is the Gileks automation unit. Such a device is connected directly to the pumping apparatus and reacts to the pressure level in the system.

The Jilex block consists of a plastic case with a metal lid. Inside the housing there is a spring, an electronic unit equipped with a pressure switch and a movable mechanism that closes the contacts when the pressure drops. For external control of the operation of the device, a manometer is mounted in the side surface of the block.

Characteristics of the Gileks automation unit

The principle of operation of the device

Automation Gileks operates autonomously from a conventional electrical network. After 30 seconds after installing and connecting the unit, it turns on and works for a few seconds. Further, the device turns off and is activated only in the event of a change in pressure in the line.

Correct installation of the device

Automation Dzhileks 9001 is installed in the supply line complete with additional equipment. Therefore, an important step is the correct installation and configuration of all components. Installation of the pressure control automation unit from Gileks is carried out in the following order:

First of all, if a modification without measuring instruments is purchased, you should purchase a pressure gauge and install it on the side panel. The mechanism is necessary to control and manage the block.
The automatic device itself crashes into the water supply line in the area between the water consumption point (faucet) and the pumping device. The unit is installed exclusively in a vertical position, with the blue metal cover up. In this case, the inlet of the device (indicated in the instructions) should be located on the side of the pump outlet. The outlet port conducts the water further into the supply line.
After the control apparatus is mounted in line, it is necessary to carefully inspect all joints and connections for tightness. If errors are found during installation, they should be sealed with sealant or connecting elements.
The unit is connected to the network strictly according to the scheme specified in the instructions. Moreover, if the device is equipped with a pump with a current of more than 10 amperes, a magnetic starter is additionally installed. The main requirement for the electrical cable used with the device is increased resistance to high temperatures.

Scheme of installation of a water supply system with automatic equipment Gileks

If necessary, the supply line is supplemented with filters for water purification and a receiver for equalizing pressure in the system.

After all the components are mounted in the trunk, it is necessary to check the device. To do this, the pump inlet through the pipeline is filled with liquid and the pump is turned on. One of the indicators on the unit immediately lights up. This indicates that there is contact between the unit and the pumping unit. The device works for several tens of seconds and then turns off.

After the device is turned off, it is necessary to open one of the taps (if there are multilevel ones, then preferably the top one). There are two options for this:

In the first case, water will flow from the tap in a continuous, uninterrupted flow. The unit turns on, and the pumping device works throughout the entire period of use of the crane. In this case, the installation of the device is correct.
If the water flow is not stable or does not exist at all, you can try to restart the device with the "Restart" button. The button is pressed and held until the pumping device works. If nothing has changed in this case, a thorough inspection of the device and the entire line is carried out, and if necessary, dismantling and adjustment.

Pump units compatible with the unit

The device works most effectively in combination with pumping devices that meet the following characteristics:

current strength in the range of 6-10 A;
device productivity up to 100 l/min;
voltage not higher than 250 V;
the maximum temperature limit of the pumped liquid is 75 degrees;
connection to a pipe with a section of 1 inch.

Other options for automation Gileks

In addition to the automation unit, the company also produces less popular automation options for pumping equipment. One of these options is the installation of Gilex Crab. The device is responsible for stable pressure in the supply line, starts and stops the pump if necessary. In addition, the filter element cleans the flow from solids.

Gilex Crab consists of the following components:

Water supply kit KRAB-50 (tank, relay, filter)

polymer hydraulic distributor;
tank receiver with a volume of 24 or 50 liters, covered with anti-corrosion enamel;
electric pressure switch;
a filter with a replaceable cartridge, which is responsible for cleaning the water stream from impurities;
manometer;
two electrical cables;
special bracket for fixing the unit to the wall.

Pressure switch RDM-5

A simpler option for automating a pumping station is to install a special RDM-5 relay on it. The compact device is mounted in the line and connected to the pumping unit using an electric cable. The wire is fixed to the relay contacts.

The principle of operation of the device is as follows. The device reacts to the level of pressure in the line. If the indicator is below the set value, the contacts are connected, current is supplied to the water intake point and the liquid fills the pipeline until the pressure returns to normal. When the pressure level returns to normal (this indicator is also set by the user), the contacts diverge. The power supply to the downhole tool is interrupted and it turns off.

The minimum and maximum indicators at which the pumping device is triggered are set by the user. You can adjust them using two nuts that fix the degree of spring tension. A larger nut, when rotated counterclockwise, sets the maximum pressure indicator, a smaller nut, when rotated, allows you to adjust the difference between the maximum and minimum pressure.

Float switch Gileks

For drainage, fecal and surface water pumps, the cheapest and most practical way to automate is the float switch. According to the scope of use, such devices are divided into light and heavy. Drainage models are equipped with a light float, heavy floats are installed at water supply stations and water pumps.

Gileks automation in the water supply system

The design consists of an electric cable 3,5,8 or 10 m long and a plastic float mechanism. Inside the float there are two contacts, a shift lever and a ball that changes the position of the lever. By the number of wires, two and three-wire floats are distinguished.

In the version with two wires, they are directly connected to the float contacts. When such a mechanism rises with the water level to the designated level, the lever presses on the contacts, they close and supply energy to the pump.

In models with three wires, the ability to turn on the fence point in the extreme upper and in the extreme lower positions is supported. To do this, one wire goes to one of the contacts, and the other two wires, depending on the position, go to the second contact.

The principle of operation of such a float mechanism is that the device automatically turns on the pump when the water level rises to the set value. In the case of a two-wire device, the float, on the contrary, opens the contacts and turns off the device when the water drops below normal.

Portal about pumps. Automation Dzhileks (unit for pump control)

Gileks automation is multifunctional, easy to set up and install, and affordable. It can work with both native pumps and pumps from other manufacturers to automate the water supply.

The company offers reliable and modern options for automation for the pump, which have a long service life and good performance. Let's take a closer look.

Total pump automation

The Gileks Crab automation unit is a device that automates the operation of an electric pump. It turns on the system when the pressure drops (the valve opens), and turns it off when the flow stops (the valve closes). Automation also lies in the protection of the pumping station during its "simple" operation - without water, on a "dry run".

Characteristics of the Gileks automation unit

The automatic Gilex block only applies to clean water that does not contain solids. If the latter are available, then a filter element must be purchased separately for the automation unit. And if you mount a pressure gauge, then pressure control can be carried out visually. To the menu

How it works?

The Gileks 9001 automatic unit turns on 30 seconds after connecting to the mains. It then turns off and goes into sleep mode. Further activation of the device occurs when the pressure changes - opening and closing the valve.

As soon as the pressure level drops to the minimum allowable rate, the control element of the automation will turn off the pump. So the safety and performance of the device is significantly extended.

After the pressure drops to the minimum allowable level, the system will not turn off immediately, but after several tens of seconds (usually from five to twenty, depending on the specific model). The delay in turning off the pumps is necessary so that, with a weak pressure of water, it does not systematically turn off. This extends the service life of the system. back to menu

Installation

To automate the control of the pump, you need to purchase the appropriate additional components for it (depending on your needs), and connect them in the following sequence:

The pressure gauge is attached to the automatic unit from the side using the fasteners included in the kit. Which side to mount - "a matter of discretion." But, it is important to carefully fix the device on the panel, without using sealing elements.
The automation unit is mounted exclusively in a vertical position. It can also be fixed in any convenient place, but on the segment between the tap (the first water intake point) and the pump supply system. Moreover, it must be done in such a way that the outer inlet of the system is adjacent to the water outlet channel from the pump, and the side outlet is adjacent to the water flow in the pipe.
All connections must be tightly fixed. It is worth making sure that they are tight and double-check the correct connection of all connecting elements.
If automatic equipment is used for electric pumping systems with a maximum pressure threshold of 15 bar, then a pressure reducer is mounted at the input of the automation.
The body of the device (or circuit board) contains the electrical circuit for connecting the automation. Strictly follow it when connecting! If a single or three-phase pump with an operating current of more than 10 amperes is used, the automation must be connected through an electromagnetic starter. The cable used to connect the device must be resistant to elevated temperatures (above 100 degrees) and non-flammable.
Automatic adjustment and operation of systems (minimum pressure) is designed for a pressure of 2 atm. This option is the most common and optimal for most systems. But, this parameter can be easily adjusted if necessary. This is done by rotating the crane, which is located on top of the automatic system, and has plus and minus markers.

Scheme of installation of a water supply system with automatic equipment Gileks

Starting the automatic system

Important! When the level of incoming water is lower than the level at which the pumping system is mounted, it is imperative to install a bottom check valve on the inlet pipe.

We start the automation as follows:

Immediately before turning on the device, we completely fill the inlet pipe of the pump with water and start it (the "Network" LED should light up). This manipulation will turn on the automation unit. As soon as the pump starts to work and, after a while, stops, you need to open the outlet valve, which is located at the highest point.
If the pump runs all the time with the tap open, and provides a continuous flow of water, the installation is considered correct. The lack of water flow indicates that you need to hold down the "Restart" button and keep it for the duration of the automatic system. If the flow is still missing during such manipulation, you need to repeat the launch.

Idle protection

When the “Protection” LED lights up on the automation unit, and the pump itself is turned off, this may indicate the danger of idle operation of the system. This is how press control works.

Recheck all systems again. If everything is in order - let the water out of the incoming system, and fill it again. Then press the "Reboot" button.to the menu

Optimal characteristics of automation for pumps

Vibrating or any other type of pump can be additionally equipped with automation systems. But, they have different parameters, properties, etc. Which ones are worth buying?

Gileks automation in the water supply system

Technical indicators (optimal):

Operating voltage = 210-250 V;
Frequency = 40/70 Hz;
Minimum working pressure = 1-4 atm.;
Load current = 6-10 A;
Water flow rate = 70-100 l/min;
Upper pressure threshold = 15 atm.;
Maximum water temperature = 75 degrees;
Inlet pipe diameter = 1 inch;
Degree of protection = 1P65.

What do you need to know?

Important! The valve located on the pipe section between the automatic / pumping systems, and the valve running on the outlet pipe of the automatic unit, are the culprits in equipment malfunctions.

The minimum working pressure of the equipment cannot be changed independently. This should be done by electricians who have experience, are familiar with regulatory documentation and comply with safety standards.

The maximum working pressure is not regulated by automation. It corresponds to the indicator of the electric pump.

Features of the operation of hydraulic accumulators Gileks - Click!

In the modern world, not a single water supply system for private houses is designed without a hydraulic tank - a hydraulic accumulator or an expansion tank.

Indeed, during operation, these devices reliably protect all components and parts of an autonomous water supply station from premature wear and failure. This article will focus on the purpose of Gileks hydraulic tanks, their design, installation features, varieties and secrets of the right choice.

Functions

The main functions that an expansion or hydraulic tank performs are:

Increasing the working life of the electromechanisms of the pumping station. During operation, the need for very frequent switching on and off of the pump is reduced, which significantly extends its service life.
Elimination of possible hydraulic shocks in an autonomous water supply system. An increase or decrease in the pressure (pressure) of water in the system negatively affects all the nodes and details of an individual water supply system. The hydraulic accumulator successfully stabilizes the pressure in the water supply and prevents the formation of gaps and leaks.
Accumulation (or accumulation) of water under a certain pressure. This feature is very useful in case of frequent power outages or low water pressure.

steel welded vessel on special legs;
flange made of galvanized steel with a threaded fitting;
butyl rubber replaceable membrane located inside the container;
air valve with cap and plastic cap;
counterflange.

The horizontal model is additionally equipped with a special platform with fasteners for installing the pump.

Specialist note: the pressure in the tank must be at least 1.5 atmospheres, and the higher this figure, the greater the water pressure in the system.

Connection options

There are several schemes for connecting the Gileks accumulator:

Connection to the deep pump. The expansion tank is located after the pump, which makes it possible to reduce the frequency of switching on and off the unit. After all, this figure is about 5 - 20 inclusions per minute, which accelerates the process of wear of the rubbing parts of the pump.
With storage water heater. In this scheme, the hydraulic tank is placed before the water heater, compensating for the thermal expansion of water in the boiler. At the same time, the higher the temperature and pressure of water, the larger the volume of the expansion tank should be.
With pressure booster pump. The hydraulic accumulator is mounted at the pump inlet, compensating for the drop in water pressure in the system at the time of its start.

To cope with the variable water pressure, which causes a lot of trouble for the inhabitants of a private house, a hydraulic accumulator for water supply systems is called upon.

A hydraulic accumulator is a special device, without which the hot and cold water supply scheme of a private house has flaws.

It is possible that you have not come across this word before, but the term "expansion tank" is familiar to almost everyone.

The principle of its installation and the connection process in heating for a private dwelling is best considered separately, but we will focus on the hot and cold water supply system.

The use of batteries in the water supply of the private sector is always relevant - whether water is used from a personal well or a pumping station is responsible for its supply.

A number of models of hydraulic accumulators are presented on the Russian market, and buyers more often choose the domestic model "Dzhileks", which combines reliable operation and a convenient price segment, which cannot be said about imported counterparts.

History reference

The prototype of a hydraulic accumulator is a water tower.

Of course, it cannot eliminate water hammer, but as an auxiliary station that optimizes the pressure in the water supply system, it is still used in some cases to this day.

During low drawdown hours, the station fills the volume of the tower with water using pumps, and during peak hours, this reserve reduces the load experienced by the station.

The same principle is now working in a hydraulic accumulator, which is very necessary in the automatic water supply system of private houses.

Purpose, types and design of hydraulic accumulators

The answer to the question: "Why do we need a hydraulic accumulator?" - very simple. A detailed lecture on this is presented to you in the video.

Hydraulic accumulators, which are used to supply water to a private house, perform three tasks:

Create the necessary pressure in the internal water supply networks of the house;
They play the role of storage of water reserves, which is very useful in case of failure of the power supply system, or if the pumping station stops supplying;
Due to their design, they significantly reduce the likelihood of water hammer in the networks of a private house.

A hydraulic accumulator is a device in the form of a metal tank, supplemented by a mechanism that creates water pressure inside it.

Subject to all connection conditions, installation of the battery and its maintenance can be done by hand.

The most common device that uses the principle of operation on the energy of compressed air. It is equipped with a partition - a rubber pear or a rubber membrane.

Just a diagram of such a hydraulic accumulator (which runs on compressed air energy) using the example of the Dzhileks model, which is widely used in automatic water supply systems, is presented to us below.

The operation scheme is as follows: the station (with the help of pumps) supplies water to the tank, which gradually fills the volume and equalizes the pressure with the air behind the membrane, this is recorded by the sensor, and the station turns off.

When water intake begins, the energy of compressed air, using pressure, pushes water from the accumulator into the internal networks of the house.

When the pressure drops, the automation is activated, the pumps are turned on, pumping water into the tank continues until the stop signal from the first sensor.

You can calculate the air pressure using the water pressure supplied by the station.

Air pressure is regulated by a manual or car pump, this simple setting is another factor influencing the choice in favor of "Dzhileks".

A similar principle of operation for piston accumulators, in which the energy of compressed air is transferred to water through a piston.

The spring device is distinguished by a low price and simplicity of design, the disadvantages include a small working volume.

Trucks are also considered simple inexpensive units, but they have a longer list of disadvantages: do-it-yourself installation complexity, large size, low operating pressure, significant energy consumption, and a complex adjustment principle.

According to the type of execution, batteries are of open and closed type.

Open devices are used less frequently, as they have a number of negative factors:

increased evaporation of water - requires additional pumping;
the installation of an open accumulator is more expensive, since it is required to exclude the possibility of water freezing, which will lead to a malfunction of the device, and additional automation is also needed to protect against overflow;
the contact of water and air makes it more aggressive towards metal parts, which causes corrosion, reducing the life of the device.

Hydraulic accumulators "Dzhileks" are made in horizontal and vertical versions, the principle and installation scheme of which is different - vertical ones occupy a smaller area during installation, and horizontal ones require a special platform for installation and connection.

In the colors of the batteries (red and blue), the generally accepted color of the pipelines of the water supply system is used.

Blue (for cold water) differ from red in that they are designed for higher pressure, and they use food grade rubber.

If you are the owner of a country house, then doing the calculation of the water supply system with your own hands, you will probably have to think about buying a hydraulic accumulator. And that raises a number of questions.

What type of battery is better to choose? How to calculate tank volume? How to calculate the water supply system? How to connect correctly? What will be the setting? Do I need to use a submersible pump?

The nuances described above will help you navigate when you make your choice among different types of batteries.

Also, before buying, you should calculate the volume of the tank.

How to choose the size?

It has been empirically established that the minimum volume of water in a tank for an ordinary private house should be at least 24 liters, some experts recommend choosing a much larger volume.

If you wish, you yourself can perform the calculation and choose a battery for a private house that meets your needs.

The key points in this case will be the performance of the pumps and the volume of peak water analysis.

The volume of water in the tank should ensure that the pump does not pump water more than 30 times per minute.

When determining the size of the accumulator itself, it must be taken into account that the water in it will occupy about a third to a half of the entire installation volume.

The video below tells about the device of the accumulator and why it is needed.

Tanks with a small volume are less effective in dealing with water hammer, however, an excessive amount of water can cause it to stagnate inside the tank.

A large accumulator must be installed on a solid base that can support the weight and volume of water stored in the tank.

You can choose which battery suits you on your own by performing the necessary calculation and reading the technical documentation, or by contacting specialists.

Secrets of installation and adjustment

As noted above, the installation of the accumulator must be carried out in a room with a positive air temperature.

The connection diagram for the example of the "Dzhileks" battery is shown in the figure below.

Your device should be located as close as possible to the water supply pump, so batteries are placed at the entrance to the house.

For maintenance and repair, it is required to drain the water from the tank, this moment must also be provided for connecting the device to the cold or hot water supply system.

If you decide to install a hydraulic accumulator with your own hands, then do not forget that instructions are attached to each product.

Do not refuse to study this important document beforehand - this will allow you to avoid possible alterations after the installation is completed, guarantees the life promised by the plant.

Setting up a hydraulic accumulator installed in an automatic water supply system is quite simple. For example, take the membrane battery "Dzhileks".

We close the valve at the entrance to the house and dump water from the water supply system.

To correctly set the pressure, we leave the water outlet open and pump air through the spool located on the tank.

The water that appeared at this moment from the tap indicates a possible malfunction - this is either a depressurization of the tank with air leakage, or a rupture of the membrane.

Let's close the discharge, fill the system with water and release air through the spool, if water appears from the spool, then it's time to change the membrane.

You can replace the membrane with your own hands, just choose original parts for this.

More and more people are making their choice using hydroaccumulators for the water supply of a private house.

A simple connection diagram and configuration, the ability to do installation and repair with your own hands and the use of automatic control of the operation of an individual pump make this device simply indispensable.

And if you happened to choose the domestic hydraulic accumulator "Dzhileks", then you will also get the best combination of price and quality equipment, which cannot be said about other imported analogues.

Portal about pumps. Automation unit for submersible, deep pump

Automation for a submersible pump is installed to regulate the flow of water and uninterrupted operation in a well or well. Thanks to this scheme, a country house, cottage, farm and other structures are provided with a reliable source of centralized water supply.

To purchase and independently install automation for pumps, you need to know the principles of operation of this mechanism, and most importantly, the submersible pump must be under water.

Instead of an introduction: types of pumps

There are two types of submersible or deep equipment:

Vibrating.
Centrifugal.

An ordinary well pump is designed for a depth of up to 10 meters. The submersible pump for lowering into a well or a deep well functions when submerged up to 50 m. Water pressure is required for operation, therefore, depending on the type of model, there are recommendations for submersion.

Submersible well pumps

Vibratory pumps are extremely common in water wells. Centrifugal devices are used on farms and in the private sector. This is due to the ease of operation and installation, stable performance and low price. The principle of operation is the rotation of the blades. They create a centrifugal force that raises pressure inside, pushing water through the pipe.

The vibratory deep pump system is popular with tech-savvy people, it is more convenient to use and more productive. Such pumps clean water and wells, they also work in a polluted environment. Therefore, when choosing the equipment necessary for water supply, first of all, pay attention to them.

The scheme of work is as follows - under the influence of current strength, the coil attracting the armature is magnetized. Because of this, the rubber piston bends, reducing the pressure filling the chamber with water. When water touches the coil, the latter is demagnetized, the piston returns to its original position, increasing the pressure in the suction chamber. The water is pushed into the injection chamber. When the water recedes from the coil, it is again magnetized and the rubber piston, bending, again creates a pressure drop that pushes water from the injection chamber into the pipeline. To the menu

Pumps with pressure sensor

A pressure switch is needed to regulate the flow of water. Thanks to it, the pressure inside the pumps is measured and automatic shutdown or on. It is directly connected to the hydraulic accumulator, which is filled thanks to the automation of the submersible pump. When the pressure drops, the relay turns on the submersible pump for the well, when filled with water, the pressure rises. When it reaches the mark specified in the settings, the relay turns off the work.

Well pump installation

The relay is connected to the submersible pump system before connecting to the power supply. The device is connected to the water supply in a specially installed place. If the manufacturer has not provided for this, then it should be connected through a brass inch tee (“herringbone”). A similar device connects both a hydraulic accumulator and a pressure gauge (pressure meter). Sometimes relays have a non-standard socket, so it is worth studying it and, if necessary, getting a brass adapter. The thread must be sealed to prevent leakage and breakage.

Connect to the mains in several stages:

two groups of contacts on the pressure sensor are determined, which open at maximum pressure;
when choosing a cable, they are guided by the power of the pump;
the wire used for grounding is connected to the relay through certain screws. The ground symbol on the screws is indicated by an inverted T with two additional horizontal stripes;
the cores of the mains wire are connected to the contacts of each individual pair of contacts on the pressure sensor. In no case should they be combined;
relay contacts are connected to the pump, observing the color of the wires. You can connect them to ground wires, but this is not necessary.

Checking the operation of the relay: turn on the pump for the well with automatic control and monitor the pressure gauge readings. As water is drawn in, the pressure will increase. When the maximum point is reached, the relay will turn off the pump. If water is consumed (you can turn on a tap or hose), then the pressure drops and, again, at a certain point, the pressure switch will turn the pump back on.

Setting up a submersible pump with automation

Automation of water intake provides easy access to water, but problems arise with the setting. The factory settings will suit most pump users. However, there is a need to change them, which requires:

De-energize the water supply system.
Drain the water until the pressure gauge shows zero.
Turn on the electricity in the water supply system.
Restart the pump and observe the increase in pressure.
At the moment when the relay turns off the pump, fix the pressure on the pressure gauge.
After that, drain the water again until the automatic system turns on the pump.
Record the switch-on pressure.
Clean filters.

Only after these manipulations start setting up. The relay has two springs. Large adjusts the maximum value, small - the difference between the maximum and minimum. To set the maximum pressure value, twist the large relay spring. If you want to adjust the minimum value, then tighten the nut on a small spring. To reduce the pressure value, the nuts are lowered.

Next, the manipulations are repeated point by point (excluding cleaning the filters) in order to make sure that the system is operating in the desired mode. It should be borne in mind that the nuts are sensitive and must be turned carefully. To the menu

Dry running protection and float switches

Dry running - this is the name of the operation of a submersible pump without enough water. This occurs due to clogging, violation of the tightness of the pipe and due to lack of water. By choosing the right model and calculating the dynamic change in water level, the last problem can be avoided.

The electrical circuit for switching on the pump protection relay against dry running

Other damage can be eliminated by regular inspection and cleaning. There are relays with an additional dry-running protection function. To do this, produce special floats and press control using automation.

Float switches are suitable for a well or a voluminous water tank. Some of them are designed to limit overflow, so you should carefully familiarize yourself with the model before installing. Those floats that prevent dry running are equipped with contacts that open when the water level drops. The cable installed on the float is positioned so that the water level is sufficient when turned off (the motor did not run dry).

Press control is suitable for submersible pumps if they are used infrequently. The control unit automatically turns on the equipment when the faucet is opened and turns it off when the faucet is closed. Depending on the settings, it turns off when the pressure drops to 1.5-2.5 bar. Go to menu

The principle of operation of the accumulator

This is an in-system tank for pressure regulation and water storage. Objectives of the hydraulic accumulator:

increasing the life of the pump, due to the fact that it turns on less often due to water reserves in the tank;
maintaining constant pressure in the pipeline;
water hammer protection;
water supply even during power outages and other problems.

Inside the accumulator tank there is a membrane that separates it into two parts. The first stores water, the second air or nitrogen. The membrane is made of butyl, a rubber material that is hygienically suitable for storing water and can withstand significant pressure. Thanks to this material, water does not come into contact with the metal of the tank walls. In some models of accumulators, a valve is provided for bleeding air, in others such a valve is installed independently.

The electric pump supplies water to the accumulator tank until the membrane expands and the pressure sensor in the air chamber turns off the relay. During the intake of water from the tank, the pressure drops, and the sensor turns on the automation. The pump with pressure sensor is adjustable. The accumulator is connected to the submersible pump control unit.

Pumps Aquarobot

Pumping systems and surface pumps Aquarobot are equipped with the necessary devices. Therefore, there is no need to buy additional relays, flow sensors and accumulators. The aquarobot is automated and configured for a different frequency of use, it is enough to choose a model.

Aquarobot protects against voltage drops, pressure, water fluctuations. Aquarobot is equipped with internal automatic protection systems against dry running, even if the electric pump breaks down. There are Aquarobot models with adaptive pumping stations of small volume - 2 and 5 liters and a universal station for 24 liters.

Connecting the automation unit to the pump

Independent piping of the automation unit for deep and submersible pumps requires power calculations. Therefore, it is better to purchase equipment from one company in advance, designed to connect with each other.

There are three main types of automation units, how to connect the unit and how to set the correct pressure settings in it depends on the type. Share:

control unit in the form of a remote control;
press control;
pressure control unit.

The first type is connected to a pressure switch. Sometimes it is possible to install directly to the float switch. It is necessary to buy additional protection against dry running, connection of a pressure switch to a submersible pump and other elements to it. Some automation units already contain all the protective elements. Press control provides the most reliable and versatile protection. The latter type is primarily designed for systems where strong pressure drops cannot be tolerated.

The automation control unit for the automation submersible pump is installed between the water intake point and the hydraulic accumulator. An arrow is indicated on the body, which must coincide with the movement of water. When using a powerful pump (with a pressure of more than 10 bar), a pressure reducer should be installed in front of the automation unit.

The submersible pump is connected to the mains and to the automation unit using fastons. The screw regulates the minimum pressure, as a rule, it is 1.5 bar. Teflon tape is recommended for sealing.

In order for the pump not to turn on every time a tap is opened in the house, a hydraulic accumulator is installed in the system. It contains a certain amount of water, sufficient for a small flow. This allows you to practically get rid of short-term switching on of the pump. Installing a hydraulic accumulator is not difficult, but a certain number of devices will be required - at least a pressure switch, and it is also desirable to have a pressure gauge and an air vent.

Functions, purpose, types

Place of installation - in the pit or in the house

In the water supply system of a private house without a hydraulic accumulator, the pump turns on whenever water flows somewhere. These frequent inclusions lead to wear of the equipment. And not only the pump, but the entire system as a whole. After all, every time there is an abrupt increase in pressure, and this is a water hammer. To reduce the number of pump turns on and smooth out the water hammer, a hydraulic accumulator is used. The same device is called an expansion or membrane tank, hydraulic tank.

Purpose

We found out one of the functions of hydraulic accumulators - to smooth out hydraulic shocks. But there are others:

Reducing the number of pump starts. There is some water in the tank. At a low flow rate - wash your hands, wash your face - water flows from the tank, the pump does not turn on. It will turn on only when there is very little of it left.
Maintain stable pressure. This function requires another element - a water pressure switch, but they maintain pressure within the required limits.
Create a small supply of water in case of a power outage.
Installing a hydraulic accumulator in a pit

It is not surprising that this device is present in most private water supply systems - there are many advantages from its use.

Kinds

A hydraulic accumulator is a sheet metal tank divided into two parts by an elastic membrane. There are two types of membrane - diaphragm and balloon (pear). The diaphragm is attached across the tank, the balloon in the form of a pear is fixed at the inlet around the inlet pipe.

By appointment, they are of three types:

for cold water;
for hot water;
for heating systems.

Hydraulic tanks for heating are painted red, tanks for plumbing are painted blue. Expansion tanks for heating are usually smaller and cheaper. This is due to the material of the membrane - for water supply it must be neutral, because the water in the pipeline is drinking.

Two types of accumulators

According to the type of location, accumulators are horizontal and vertical. Vertical ones are equipped with legs, some models have plates for hanging on the wall. It is the models that are elongated upwards that are more often used when creating the plumbing systems of a private house on their own - they take up less space. The connection of this type of accumulator is standard - through a 1-inch outlet.

Horizontal models are usually completed with pumping stations with surface-type pumps. Then the pump is placed on top of the tank. It turns out compact.

Principle of operation

Radial membranes (in the form of a plate) are used mainly in gyroaccumulators for heating systems. For water supply, a rubber bulb is mainly installed inside. How does such a system work? As long as there is only air inside, the pressure inside is standard - the one set at the factory (1.5 atm) or which you set yourself. The pump turns on, starts pumping water into the tank, the pear begins to grow in size. Water gradually fills an increasing volume, more and more compressing the air that is between the tank wall and the membrane. When a certain pressure is reached (usually for one-story houses it is 2.8 - 3 atm), the pump turns off, the pressure in the system stabilizes. When you open a tap or other flow of water, it comes from the accumulator. It flows until the pressure in the tank drops below a certain level (usually about 1.6-1.8 atm). Then the pump turns on, the cycle repeats again.

The principle of operation of a gyroaccumulator with a pear-shaped membrane

If the flow is large and constant - you are taking a bath, for example, - the pump pumps water in transit, without pumping it into the tank. The tank begins to fill after all the taps are closed.

The water pressure switch is responsible for turning the pump on and off at a certain pressure. In most accumulator piping schemes, this device is present - such a system works in the optimal mode. We will consider connecting the accumulator a little lower, but for now let's talk about the tank itself and its parameters.

Large volume tanks

The internal structure of accumulators with a volume of 100 liters and above is slightly different. The pear is different - it is attached to the body both above and below. With this structure, it becomes possible to deal with the air that is present in the water. To do this, there is an outlet in the upper part, into which a valve for automatic air release can be connected.

The structure of a large hydraulic accumulator

How to choose tank volume

You can choose the volume of the tank arbitrarily. There are no requirements or restrictions. The larger the tank, the more water you will have in case of a shutdown and the less often the pump will turn on.

When choosing a volume, it is worth remembering that the volume that is in the passport is the size of the entire container. Water in it will be almost half less. The second thing to keep in mind is the overall dimensions of the container. A 100 liter tank is a decent barrel - about 850 mm high and 450 mm in diameter. For her and the strapping, it will be necessary to find a place somewhere. Somewhere - this is in the room where the pipe comes from the pump. This is where most of the equipment is installed.

The volume is chosen based on the average consumption

If you need at least some guidelines to choose the volume of the accumulator, calculate the average flow rate from each draw-off point (there are special tables or you can see it in the passport for household appliances). Sum all these data. Get the possible flow rate if all consumers work at the same time. Then estimate how many and which devices can work at the same time, calculate how much water will go in this case per minute. Most likely by this time you will already come to some kind of decision.

To make it a little easier, let's say that the volume of the hydraulic tank of 25 liters is enough to meet the needs of two people. It will ensure the normal functioning of a very small system: a faucet, a toilet bowl, a sink and a small water heater. In the presence of other household appliances, the capacity must be increased. The good news is that if you decide that the existing tank is not enough for you, you can always install an additional one.

What should be the pressure in the accumulator

Compressed air is in one part of the accumulator, water is pumped into the second. The air in the tank is under pressure - factory settings - 1.5 atm. This pressure does not depend on volume - and on a tank with a capacity of 24 liters and 150 liters it is the same. More or less may be the maximum allowable maximum pressure, but it does not depend on the volume, but on the membrane and is indicated in the technical specifications.

The design of the hydraulic accumulator (image of flanges)

Pre-check and pressure correction

Before connecting the accumulator to the system, it is advisable to check the pressure in it. The settings of the pressure switch depend on this indicator, and during transportation and storage the pressure could drop, so control is very desirable. You can control the pressure in the gyro tank using a pressure gauge connected to a special inlet in the upper part of the tank (capacity of 100 liters or more) or installed in its lower part as one of the piping parts. Temporarily, for control, you can connect a car pressure gauge. The error is usually small and it is convenient for them to work. If this is not the case, you can use the regular one for water pipes, but they usually do not differ in accuracy.

Connect pressure gauge to nipple

If necessary, the pressure in the accumulator can be increased or decreased. To do this, there is a nipple at the top of the tank. A car or bicycle pump is connected through the nipple and, if necessary, the pressure is increased. If it needs to be bled off, the nipple valve is bent with some thin object, releasing air.

What air pressure should be

So the pressure in the accumulator should be the same? For the normal operation of household appliances, a pressure of 1.4-2.8 atm is required. To prevent the tank membrane from tearing, the pressure in the system should be slightly higher than the tank pressure - by 0.1-0.2 atm. If the pressure in the tank is 1.5 atm, then the pressure in the system should not be lower than 1.6 atm. This value is set on the water pressure switch, which is paired with a hydraulic accumulator. These are the optimal settings for a small one-story house.

If the house is two-story, you will have to increase the pressure. There is a formula for calculating the pressure in a hydraulic tank:

Vatm.=(Hmax+6)/10

Where Hmax is the height of the highest draw point. Most often it is a shower. You measure (calculate) at what height relative to the accumulator its watering can is, substitute it into the formula, you get the pressure that should be in the tank.

Connecting a hydraulic accumulator to a surface pump

If the house has a jacuzzi, everything is more complicated. You will have to select it empirically - by changing the relay settings and observing the operation of water points and household appliances. But at the same time, the working pressure should not exceed the maximum allowable for other household appliances and plumbing fixtures (indicated in the technical specifications).

How to choose

The main working body of the hydraulic tank is the membrane. Its service life depends on the quality of the material. The best for today are membranes made of isobutyl rubber (it is also called food grade). The body material matters only in membrane type tanks. In those in which a "pear" is installed, water contacts only with rubber and the material of the case does not matter.

The flange should be made of thick galvanized steel, but stainless steel is better

What is really important in tanks with "pears" is the flange. Usually it is made of galvanized metal. In this case, the thickness of the metal is important. If it is only 1 mm, after about a year and a half of operation, a hole will appear in the metal of the flange, the tank will lose its tightness and the system will stop working. Moreover, the guarantee is only a year, although the declared service life is 10-15 years. The flange usually deteriorates after the end of the warranty period. There is no way to weld it - a very thin metal. You have to look for a new flange in service centers or buy a new tank.

So, if you want the accumulator to serve for a long time, look for a flange made of thick galvanized steel or thin, but made of stainless steel.

Connecting the accumulator to the system

Typically, the water supply system of a private house consists of:

pump;
hydraulic accumulator;
pressure switch;
check valve.
Hydraulic accumulator connection diagram

A pressure gauge may also be present in this circuit - for operational pressure control, but this device is not necessary. It can be periodically connected - for test measurements.

With or without 5-pin fitting

If the pump is of a surface type, the accumulator is usually placed near it. In this case, a check valve is installed on the suction pipeline, and all other devices are installed in one bundle. They are usually connected using a five-pin fitting.

Five-pin fitting for tying the accumulator

It has leads with different diameters, just for the devices used for tying the accumulator. Therefore, the system is most often assembled on its basis. But this element is not at all necessary and everything can be connected using ordinary fittings and pieces of pipes, but this is a more time-consuming task, and there will be more connections.

How to connect a hydraulic accumulator to a well - a diagram without a five-pin fitting

With one inch outlet, the fitting is screwed onto the tank - the branch pipe is located below. A pressure switch and pressure gauge are connected to the 1/4 inch outlets. A pipe from the pump and wiring to consumers are connected to the remaining free inch outlets. That's all the connection of the gyroaccumulator to the pump. If you are assembling a water supply scheme with a surface pump, you can use a flexible hose in a metal winding (with inch fittings) - it is easier to work with it.

A visual diagram of the connection of the pump and accumulator - where necessary, use hoses or pipes

As usual, there are several options, you choose.

Connect the accumulator to the submersible pump in the same way. The whole difference is where the pump is installed and where to supply power, but this has nothing to do with installing a hydraulic accumulator. He puts it in the place where the pipes from the pump go. Connection - one to one (see diagram).

Scheme of connecting a hydraulic accumulator to a submersible pump

How to install two hydraulic tanks on one pump

When operating the system, sometimes the owners come to the conclusion that the available volume of the accumulator is not enough for them. In this case, a second (third, fourth, etc.) hydraulic tank of any volume can be installed in parallel.

Connection of several hydraulic tanks in one system

There is no need to reconfigure the system, the relay will monitor the pressure in the tank on which it is installed, and the viability of such a system is much higher. After all, if the first accumulator is damaged, the second one will work. There is another positive point - two tanks of 50 liters each cost less than one of 100. The point is in a more complex technology for the production of large containers. So it's also more cost effective.

How to connect a second accumulator to the system? Screw a tee onto the input of the first one, connect the input from the pump (five-pin fitting) to one free output, and the second container to the remaining free output. All. You can test the circuit.

No. Judging by the same instructions, the automation turns off the pump with a delay of several seconds. Those. pressure should rise above 1.5 atm.

It should, but it's stalling nonetheless. In the same instructions, there are no hints about the use of HA and a warning that check valves may interfere with the operation of the unit.

winder you do not rotate chaotically .. made one revolution (clockwise) looked on and off .. then again.
That's it! There is a warning about OK, but they are trying hard to stick it.
The pump is turned off in this way: when the flow sensor is triggered, there is a software delay for turning off, during this time the pump gains the maximum possible pressure determined by the suction height and the loss in the system ...

I'll repeat the question, maybe they didn't notice.
winder, what pressure does the manometer show at the moment the protection is triggered?
Registration: 05.07.07 Messages: 12.384 Acknowledgments: 15.982

Please excuse me if I'm repeating myself.
Option 1 - the pressure in the GA should be a little in this case above lower switching point of automation
2. Play around with setting the second OK in front of the GA - the pressure in the GA is below the lower threshold for switching on the BA
IMHO - the protection does not work because of the pressure in this case, but because of the lack of water flow - the water seems to be flowing from the tap, the pressure drops, the pump turns on, but- water in the tap flows from the GA and does not flow in the proper volume through the BA.
Apparently, there are certain subtleties in the operation of a BA with such a pump - a surface vortex pump with a built-in ejector. I didn't have that.
Registration: 02.01.10 Messages: 3.196 Acknowledgments: 329

Seems to me a very simple thing.
Once the flow switch, then even if we fill the HA, then when the tap is opened, the unit will see the flow and turn on the pump with a delay without waiting for the HA to give water. Of course, I can be wrong, but while the consumer takes water from the GA, the Block must be cut off.

3. Throw out the BA and stupidly put two standard relays - pressure and dry running.

I'm late with the idea.
... IMHO - the protection does not work because of the pressure in this case, but because of the lack of water flow - the water seems to be flowing from the tap, the pressure drops, the pump turns on, but- water in the tap flows from the HA and does not flow in the proper volume through the BA ...

And if you move the GA to the BA (that is, immediately after the pump), as if the glitch (emergency shutdown) should disappear.
But I'm somewhat confused by the following statement of the topikstarter.

It is understood that this byaka occurs when the GA is connected.
And without GA, as if the norm.

... After switching on, the pump works a little (pressure 1.5), then water is leaking from the chamber and protection works on BA. To start again, you have to fill the pump chamber with water again ...

Some kind of poltergeist.
And, as he claims winder OK stands at the end of the fence and

... water from the pump housing does not drain back into the well. She is in principle cannot merge, such is the design, the suction pipe at the highest point. And the pump to suck water, no water is needed in the suction hose itself, enough of the one in the case to start working properly.

the water has nowhere to go from the pump.
But it turns out that the author has to add water (in the presence of GA).

...To start again, you have to fill the pump chamber again with water…

Miracles.
Or winder, says something wrong.

Here is what I think winder something does not agree!

Logically.
And if you move the GA to the BA (that is, immediately after the pump), as if the glitch (emergency shutdown) should disappear.

Not entirely logical. And where does the water flow from without HA?

If you move the HA to the BA, and it is better to put RD and LP / 3 instead of the BA, and check OK in the well, then the AO should disappear, and the NS will work.

Interestingly, the guests who accidentally came into this topic understand something?
I finish everything I wrote earlier that the water from the pump just goes into the HA.
But that's in the past everything is running now, works as expected, HOORAY! The valve was not needed, it does not work even with the GA turned off.
What he did was to stick a tap from the tee to the GA so that the GA could be quickly turned off. I'll post a picture and move on...
Registered: 18.05.09 Messages: 2.843 Acknowledgments: 2.201 torez-1 A nescire ad non esse

The valve was not needed, it does not work even with the GA turned off.

Which once again confirms that the instructions must be followed!
Registration: 25.10.08 Messages: 20.160 Acknowledgments: 12.605

So, after unsuccessful attempts to get it to work with OK, I removed it again.
First I launched it with the GA disabled, I made sure that everything was working again. Then, while the pump was running and the supply was open, he opened the tap on the HA, then closed the supply, the pressure began to increase, in the transparent filter it can be seen that water is still coming from the well - it is filled with the HA, when it was filled (after 2 minutes) the pump turned off. I opened the supply, the pressure drops, the pump is silent, it has fallen, and the pump has not started, then I twist the adjustment on the BA to “-” until the pump is turned on. And voila, after that everything works tip-top!
Now the work looks like this, after opening the tap for supply, first the GA gives off water from itself to a pressure of 1.5 points, then the pump turns on and works until the tap is open, after closing the supply tap, the pump works for a couple more minutes (instead of 15 seconds before without GA) filling GA up to 3.5 points and turns off.

Good job!
Registration: 25.10.08 Messages: 20.160 Acknowledgments: 12.605

Apparently the last question. At what pressure is the GA pumped up now?
Good job!

About 1.5, now I myself am suffering, whether it is there a little less or a little more than the operation of the BA, because I measured the auto pump with a pressure gauge, it’s not a fact that they and the BA pressure gauge seem the same.
Registration: 23.10.08 Messages: 3.413 Acknowledgments: 1.938

... because I measured the auto pump with a pressure gauge, it’s not a fact that they look the same with a BA pressure gauge.

Checking the readings of these two pressure gauges is elementary.

When the pump builds up a pressure of 3.5 points (an interesting unit) and turns off, check the pressure on the “air” GA nipple with an automanometer.
With serviceable pressure gauges, the pressure will show the same.
For example, 3.5 points, + - the difference in the accuracy class of instruments.

... I wrote earlier that the water from the pump just goes into the HA.
But that's in the past...

I guess I'm a pessimistic slow-witted, but before

... Without GA everything is fine, but with GA it does not want to.
After switching on, the pump works a little (pressure 1.5), then from camera is running out of water…
...To start again, have to refill the chamber water pump.

I still don’t understand how the water “managed” to leave the pump (before the chambers were exposed, followed by topping up with water) and “hide” in the GA?

1 Features of the company control unit

1.1 How the instrument works

1.2 JELEX AUTOMATIC UNIT (JILEKS): WE CONSIDER THE INSIDE (VIDEO)

2 Correct installation of the device

First of all, if a modification without measuring instruments is purchased, you should purchase a pressure gauge and install it on the side panel. The mechanism is necessary to control and manage the block.
The automatic device itself crashes into the water supply line in the area between the water consumption point (faucet) and the pumping device. The unit is installed exclusively in a vertical position, with the blue metal cover up. In this case, the inlet of the device (indicated in the instructions) should be located on the side of the pump outlet. The outlet port conducts the water further into the supply line.
After the control apparatus is mounted in line, it is necessary to carefully inspect all joints and connections for tightness. If errors are found during installation, they should be sealed with sealant or connecting elements.
The unit is connected to the network strictly according to the scheme specified in the instructions. Moreover, if the device is equipped with a pump with a current of more than 10 amperes, a magnetic starter is additionally installed. The main requirement for the electrical cable used with the device is increased resistance to high temperatures.

If necessary, the supply line is supplemented with filters for water purification and a receiver for equalizing pressure in the system.

After the device is turned off, it is necessary to open one of the taps (if there are multilevel ones, then preferably the top one). There are two options for this:

In the first case, water will flow from the tap in a continuous, uninterrupted flow. The unit turns on, and the pumping device works throughout the entire period of use of the crane. In this case, the installation of the device is correct.
If the water flow is not stable or does not exist at all, you can try to restart the device with the "Restart" button. The button is pressed and held until the pumping device works. If nothing has changed in this case, a thorough inspection of the device and the entire line is carried out, and if necessary, dismantling and adjustment.

3 Pump units compatible with the unit

The device works most effectively in combination with pumping devices that meet the following characteristics:

current strength in the range of 6-10 A;
device productivity up to 100 l/min;
voltage not higher than 250 V;
the maximum temperature limit of the pumped liquid is 75 degrees;
connection to a pipe with a section of 1 inch.

4 Other options for automation Gileks

Gilex Crab consists of the following components:

polymer hydraulic distributor;
tank receiver with a volume of 24 or 50 liters, covered with anti-corrosion enamel;
electric pressure switch;
a filter with a replaceable cartridge, which is responsible for cleaning the water stream from impurities;
manometer;
two electrical cables;
special bracket for fixing the unit to the wall.

The device and principle of operation of the water pressure switch

Structurally, the relay is made in the form of a compact unit with maximum and minimum pressure springs, the tension of which is regulated by nuts. The membrane connected to the springs reacts to changes in the pressure force. Upon reaching the minimum value, the spring weakens, at the maximum level, it is compressed more strongly. The force exerted on the springs causes the opening (closing) of the relay contacts, turning the pump off or on.

The presence of a relay in the water supply system allows you to provide a constant pressure in the system and the necessary water pressure. The pump is controlled automatically. Properly set levels of minimum and maximum pressure ensure its periodic shutdown, which contributes to a significant increase in the period of trouble-free service.

The sequence of operation of the pumping station under the control of the relay is as follows:

The pump pumps water into the tank.
The water pressure is constantly increasing, which can be tracked on the pressure gauge.
When the set upper pressure limit is reached, the relay is activated and turns off the pump.
As the water pumped into the tank is used up, the pressure decreases. When it reaches the lower level, the pump will turn on again and the cycle will repeat.

The main parameters of the relay operation:

Lower pressure (switch-on level). The relay contacts that turn on the pump are closed, and water enters the tank.
Upper pressure (off level). The relay contacts open, the pump turns off.
Pressure range - the difference between the two previous indicators.
The value of the maximum allowable shutdown pressure.

Setting the pressure switch

During the assembly process of the pumping station, special attention is paid to setting the pressure switch. The ease of operation of the water supply system, as well as the terms of the trouble-free service of all components of the device, depend on how correctly its limiting levels are set.

At the first stage, you need to check the pressure that was created in the tank during the manufacture of the pumping station. Usually, at the factory, the on-off level is set to 1.5 atmospheres, and the off level is 2.5 atmospheres. This is checked with an empty tank and the pumping station disconnected from the mains. It is recommended to check with an automotive mechanical pressure gauge. It is placed in a metal case, so the measurements are more accurate than using electronic or plastic pressure gauges. Their readings can be affected by both the air temperature in the room and the level of battery charge. It is desirable that the scale limit of the pressure gauge be as small as possible. Because on a scale of, for example, 50 atmospheres, it will be very difficult to accurately measure one atmosphere.

To check the pressure in the tank, you need to unscrew the cap that closes the spool, connect a pressure gauge and take a reading on its scale. The air pressure should continue to be checked periodically, for example once a month. In this case, water must be completely removed from the tank by turning off the pump and opening all taps.

Another option is also possible - carefully monitor the shutdown pressure of the pump. If it has increased, this will mean a decrease in air pressure in the tank. The lower the air pressure, the more water can be created. However, the pressure spread from a completely filled to a practically empty tank is large, and all this will depend on the preferences of the consumer.

Having chosen the desired mode of operation, you need to set it by bleeding excess air for this, or pump it up additionally. It must be borne in mind that one should not reduce the pressure to a value of less than one atmosphere, and also pump it too much. Due to the small amount of air, the rubber container filled with water inside the tank will touch its walls and be wiped. And excess air will not make it possible to pump in a lot of water, since a significant part of the tank volume will be occupied by air.

Setting the pump on and off pressure levels

In pumping stations that are delivered assembled, the pressure switch is pre-configured according to the best option. But when it is installed from various elements at the place of operation, the relay must be configured. This is due to the need to ensure an effective relationship between the relay settings and the volume of the tank and the pump head. In addition, it may be necessary to change the initial setting of the pressure switch. The procedure for this should be as follows:

In practice, the power of the pumps is chosen such that it does not allow pumping the tank to the extreme limit. Typically, the cut-off pressure is set a couple of atmospheres above the turn-on threshold.

It is also possible to set pressure limits that differ from the recommended values. In this way, you can set your own version of the operating mode of the pumping station. Moreover, when setting the pressure difference with a small nut, one must proceed from the fact that the starting point of reference should be the lower level set by the large nut. You can set the upper level only within the limits for which the system is designed. In addition, rubber hoses and other plumbing also withstand pressure, not higher than the calculated one. All this must be taken into account when installing the pumping station. In addition, the excessive pressure of water from the tap is often completely unnecessary and uncomfortable.

Back to content

Pressure switch adjustment

Adjustment of the pressure switch is practiced in cases where it is necessary to set the levels of upper and lower pressures to the specified values. For example, you want to set the upper pressure to 3 atmospheres, the lower - 1.7 atmospheres. The adjustment process is as follows:

Turn on the pump and pump water into the tank to the pressure on the pressure gauge of 3 atmospheres.
Switch off the pump.
Open the relay cover and slowly turn the small nut until the relay operates. Turning the nut clockwise means an increase in pressure, in the opposite direction - a decrease. The upper level is set - 3 atmospheres.
Open the tap and drain the water from the tank to the pressure value on the pressure gauge of 1.7 atmospheres.
Shut off valve.
Open the relay cover and slowly turn the large nut until the contacts actuate. The lower level is set - 1.7 atmospheres. It should be slightly higher than the air pressure in the tank.

If high pressure is set to turn off and low to turn on, the tank fills with more water and it is not necessary to turn on the pump frequently. The inconvenience arises only because of the large pressure difference when the tank is full or almost empty. In other cases, when the pressure range is small, and the pump often has to be pumped up, the water pressure in the system is uniform and quite comfortable.

In the next article, you will learn about connecting a hydraulic accumulator to a water supply system - the most common connection schemes.

How does a pressure switch on a hydraulic accumulator work?

A hydraulic accumulator, together with a pressure switch and a pump, are the most important parts of the water supply for a summer residence, a farm and other buildings. A properly configured and installed sensor allows you to save the owner from most of the problems associated with water.

Connecting a pressure switch and installing additional equipment is not an easy process, it requires attention and specific knowledge in electronics and the operation of a pumping station with a hydraulic accumulator.

1 Description of sensor and pumping system

The water pressure sensor is an electrical device that regulates the pressure in the accumulator for a pumping station. It also monitors the pressure of the liquid in the pipeline and turns on or off the water supply to the accumulator tank.

This happens due to the short circuit of the wires. Exceeding the allowable threshold opens the contacts and the relay turns off the pump. A drop below the set level closes the contact of the device, including the water supply. You can manually adjust both the upper and lower thresholds.

Scheme of operation of the pressure switch

Basic concepts of a pressure switch for a system with a hydraulic accumulator:

Rvkl - lower pressure threshold, power on, in standard settings it is 1.5 bar. The contacts are connected, and the pump connected to the relay begins to pump water;
Roff - the upper pressure threshold, switching off the power supply of the relay, it is better to set it to 2.5-3 bar. The circuit is disconnected and an automatic signal stops the pumps;
delta P (DR) - an indicator of the pressure difference between the lower and upper thresholds;
maximum pressure - as a rule, does not exceed 5 bar. This value is displayed in the characteristics of the control device for water supply systems and does not change. Excess leads to damage to the equipment or a reduction in the warranty period.

The main element of the pressure switch for the accumulator is a membrane that responds to water pressure. It bends depending on the pressure and tells the mechanism how much the water pressure in the pumping station rises or falls. The bend switches the contacts inside the relay. A special spring counteracts the onslaught of water (which is tightened for adjustment). The smaller spring determines the differential, that is, the difference between the lower and upper pressure thresholds.

Relays can be of two types. The first, power, directly acts on the contacts of the pump. The control type interacts with the automation of the station and through it affects the operation of the pump.

A hydraulic accumulator and a pressure switch form a reliable system for providing water supply to any premises, outbuildings, fields and more. Automation for the pump is also a necessary part - thanks to it, it becomes as simple as possible to control the collection of water and quickly pump liquid into the tank and into the pipes.

1.1 Adjusting the pressure switch for the accumulator

Before connecting the equipment to the tank, you should check the operation of the relay and adjust it. It is recommended to take readings with a mechanical pressure gauge. It is more points and less prone to internal breakdowns, due to which its readings may not correspond to reality.

The following will be instructions on how to properly set up the pressure switch. First of all, you need to familiarize yourself with the passport of the device, the pump and the accumulator tank in order to find out the pressure limits for these elements of the pumping station. Best when buying familiarize yourself with these parameters in advance and adjust them to each other.

Open the water intake (faucet, hose, valve) so that, thanks to the pressure gauge, you can see the pressure at which the relay trips and the pump turns on. Usually it is 1.5-1 bar.
Water consumption is turned off to increase the pressure in the system (in the accumulator tank). The pressure gauge fixes the limit at which the relay turns off the pump. Usually it is 2.5-3 bars.
Adjust the nut attached to the large spring. It defines the value at which the pump is switched on. To increase the switching threshold, tighten the nut clockwise; to decrease it, loosen it (counterclockwise). Repeat the previous points until the switch-on pressure does not correspond to the desired one.
The switch-off sensor is adjusted with a nut on a small spring. She is responsible for the difference between the two thresholds and the setting principle is the same: to increase the difference (and increase the shutdown pressure) - tighten the nut, to reduce - loosen.
It is not recommended to turn the nut more than 360 degrees at a time, as they are very sensitive.

1.2 How to set up a pressure switch at a pumping station? (video)

2 Accumulator pump

Since the sensor also determines the air pressure in the accumulator of the pumping station, you should also know the description of this equipment. This will ensure proper connection of the accumulator. If you seriously think about how to choose a hydraulic accumulator, then you should pay attention to the following items.

The device is a metal tank of 19, 24, 50 liters or more, up to 1000. Tanks of 50 and 24 liters are the most common for summer cottages and small country houses. However keep in mind that the total volume of the tank is not the volume of water. which it may contain. Inside the accumulator tank, the air pressure should be approximately 0.2-0.3 bar less than in the pipeline.

It is necessary to choose taking into account the settings of the pressure switch, the higher the settings and the more durable the device, the more water can be loaded into the tank. So in a pumping station with a tank of 24 liters, at a pressure Рoff equal to 2.5, and Рon equal to 1.0, the volume of stored water will be 9 liters with a little. Special tables will allow you to correctly select the volume of the tank and the power of the pressure switch. Which one is better depends on the depth of the well, the length of the pipeline and the frequency and purpose of use.

Pumping stations with a hydraulic accumulator are pear and membrane. The first type has an internal rubber container, a “pear”, into which air is pumped by a pump. The pear expands and presses on the water inside the tank, ensuring its flow through the pipes. How to pump air into the "pear"?

Accumulator pump

To do this, use a conventional air pump and a car nipple. In the membrane, it is arranged a little differently: water is pumped into the rubber container (from butyl), while air presses from the outside of the container. Air is located between the metal walls of the tank and the membrane with water.

The hydraulic accumulator is connected to the submersible pump through a system consisting of the following elements:

pressure switch;
dry running sensor;
pipeline circuit;
water purification filters;
automation unit and additional equipment.

2.1 Checking the accumulator pressure

Before being connected to the network and the pumping system, the accumulator must pass a pressure test. Since the principle of operation of the pumping station is to pressurize the pipes using relays, pumps and a hydraulic accumulator, checking is an extremely important operation. Monitoring the level of air pressure, which will change over time due to wear, breakdowns, clogging, is the most difficult part of pumping station prevention.

Indicators are taken with a manometer. It is necessary to remove the decorative cap and connect the pressure gauge to the accumulator tank nipple. A figure of 1.5 bar is usually considered acceptable.. however, less is also suitable - up to 0.8, depending on the type of tank. Thus, the accumulator for the pumping station is configured.

Accumulator connection tool kit

Adjusting the air pressure inside the tank will allow you to change the water pressure. The higher the water pressure, the faster the wear of the system. Low water pressure will not allow you to use a hydromassage shower or jacuzzi, but will significantly save money on repair and replacement of parts of the hydropump system.

2.2 How to connect the accumulator to the relay?

The relay is connected to the mains with two pairs of contacts. The connection to the pipeline is made using a threaded hole, the standard diameter of which is 0.25 inches (6 millimeters). In order to independently provide a pressure switch pumping station, the following tools are required:

coupling with a union nut (popularly "American"), as a rule, a diameter of 1 ”is used;
coupling with collet clamp;
MRN clutch;
brass adapter;
hermetic sealing tape (preferably FUM, it ensures a stable connection of the pump to the accumulator);
pipes, fittings, pressure switch, hydraulic accumulator.

Scheme of connecting the accumulator to the water supply

The scheme for connecting a hydraulic accumulator to a pumping station with your own hands is as follows:

The threads of the accumulator tank need to be sealed with tape to avoid water leaks, air infiltration into the system, facilitate maintenance, and also for easier subsequent repair and replacement of pipes.
The pressure switch is not connected directly, but using a coupling with a union nut. This is also done for ease of further repair of equipment and tighter insulation of the pipeline. This coupling, among other things, facilitates both connection and subsequent adjustment of automation.
The relay is connected at the required angle so that when the equipment is installed, you can easily monitor the indicators. Here they take into account that sometimes all automation is placed in hard-to-reach places - in narrow nooks and crannies, small technical rooms, even lowered inside a closed well or well. Therefore, it is very important to determine the required angle of the relay and it is possible to connect it to other works, and not directly to the tank.
Just in case, the pressure gauge can also be glued with sealed tape, although a gasket is used there.
From plastic pipes and fittings, it is required to solder an elbow for the consumer line.
The regulator is connected to the knee thanks to the MPH coupling soldered to the pipe and using a brass adapter.
For deep, submersible pumps, polyethylene pipes are more often used. To hermetically connect them to the relay, a collet coupling is required.
The preparatory part is completed and then it is required to connect the accumulator and pressure switch to the rest of the pumping station.
After connecting to the pipeline, it is necessary to connect the electricity.
The fastening of the regulator cover is unscrewed with a conventional screwdriver. Inside there are inlet holes to which power wires are connected. and pump cable. Contacts are signed, or they are indicated in the instructions.

In this way, the pressure switch and the hydraulic accumulator are connected to the pumping station.

Setting the pressure switch and adjusting the air pressure in the accumulator.

Pressure switch- an element that controls the operation of the pumping station (for example AQUAJET or AQUAJET-INOX) and which makes it possible to work in automatic mode. The pressure switch has several characteristics:

Switching pressure (P on) is the pressure (bar) at which the pumping station is turned on by closing the contacts in the pressure switch. Sometimes the switch-on pressure is also referred to as the “lower” pressure.
Shutdown pressure (P off) is the pressure (bar) at which the pumping station is turned off by opening the contacts in the pressure switch. Sometimes the cut-off pressure is also referred to as the "top" pressure.
Pressure drop (∆P) is the absolute difference between the switch-off pressure and the switch-on pressure (bar).
Maximum shutdown pressure- this is the maximum pressure (bar) at which the pumping station can be turned off.

Any pressure switch has factory settings and, as a rule, they are as follows:
Switching pressure: 1.5-1.8 bar
Cut-off pressure: 2.5-3 bar
Maximum shutdown pressure: 5 bar

How it all works:
Suppose the pumping station is connected (more on this in the article “Preparing the DAB pumping station for operation”), and the entire system is filled with water. After opening any faucet (shower, sink, etc.) and the start of water intake, the pressure in the system will begin to drop smoothly (thanks to the membrane hydraulic tank), which is easy to track on the pressure gauge. All this time, water is supplied to the consumer from the hydraulic tank. When the “lower” switch-on pressure is reached (it can also be monitored on the pressure gauge at the moment the pump is turned on), the contacts inside the pressure switch will close and the pump will start. The rest of the time the pump continues to work, supplying water directly to the consumer. After the completion of the water intake (all taps are closed), the pump still continues to work, only now the water is not supplied to the consumer, but is pumped into the hydraulic tank (because there is nowhere else for it to go) and the pressure gradually increases. When the cut-off pressure is reached (can be easily tracked on the pressure gauge at the moment the pump stops), the contacts inside the pressure switch open and the pump stops. At the next drawdown, the cycle repeats. Everything is pretty simple.

But what if the factory settings of the pressure switch are not very comfortable? For example:on the upper floors, the pressure drops very noticeably, or the water treatment system requires at least 2.5 bar at the inlet, while the pump turns on only at 1.5-1.8 bar.

You can also set up the pressure switch yourself:

We record the on and off pressure on the pressure gauge with the pump running. We disconnect the power from the pump and remove the top cover of the pressure switch (usually by unscrewing one screw). You will see two screws, one larger one at the top of the relay and a slightly smaller one underneath it. The top screw is responsible for the shutdown pressure and, as a rule, next to it is the letter "P" and an arrow with the signs "+" and "-". Then we turn the screw in the desired direction (if the shut-off pressure needs to be raised, then we turn it in the direction of the “+” sign, if we lower it, then in the direction of the “-” sign). How much to rotate? Make a turn (half a turn, one and a half - as much as you want). After that, we start the pump and see at what pressure it will turn off now. We remember, turn off the power to the pump, and turn the screw further, start the pump again and record a new value, thus approaching the desired value.

The bottom screw is responsible for the difference between the cut-off pressure and the turn-on pressure. As a rule, “ΔP” is written next to it and there is an arrow with “+” and “-” signs. Setting the differential pressure is similar to setting the switch-off pressure. There is only one question left, what should it be? The difference between the on and off pressure is usually 1.0-1.5 bar. Moreover, the higher the shutdown pressure, the greater this difference can be. For example, at factory settings P on = 1.6 bar, P off = 2.6 bar, the difference is 1 bar, this is just the standard value. If we want to change the factory settings and raise P off to 4 bar, then the difference can be made to 1.5 bar, i.e. P on must be set at 2.5 bar. It must be understood that the greater this difference, the higher the pressure drop in the system, which is not always comfortable. But at the same time, the pump will turn on less often, and more water will come from the hydraulic tank until the pump is turned on.

This is only true if the pump can supply the required pressure (see pump specification). Those. if the pump can only deliver 3.5 bar according to the passport (taking into account all types of losses), then setting the pressure switch to turn off 4 bar will not work. The pump simply will not be able to provide the required pressure and in this case will work without stopping. And if you still need exactly 4 bar, then you will have to change the pump to a more powerful one.

What should be the air pressure in the air cavity of the hydraulic tank?

A lot of people do not think, or simply do not know that they also need to monitor this. Unfortunately, yes, it is necessary, the service life of the hydraulic tank membrane, and ultimately the pump, directly depends on this.

We measure the air pressure in the air cavity of the hydraulic tank. Doing it only on a hydraulic tank disconnected from the system- turn off the power to the pump, open any tap behind the pump and wait until the water comes out of the hydraulic tank. Or we measure at the installation not yet connected to the water supply system. To do this, remove the decorative cap from the air nipple of the hydraulic tank and connect a regular car pressure gauge to it (to check the pressure in the car's tires). Remember this pressure. (As a rule, on small hydraulic tanks, with a capacity of up to 50 liters, this pressure will be equal to 1.5 bar). Now the most important rule : the air pressure in the hydraulic tank must be less than the switching pressure of the pump by about 10%. Those. if the pump start pressure is 1.6 bar, then the air pressure should be 1.4-1.5 bar. In most cases, these are the factory settings mentioned above. Those. when buying a ready-made pumping station, you already have a fully configured system. But once you have made changes to the factory settings of the pressure switch, you must always change the air pressure in the hydraulic tank. For example, if you set P on = 2.5 bar, P off = 3.5 bar, then you need to raise the air pressure to a value of 2.2-2.3 bar.

By the way, even if you did not change anything in the factory settings, you must regularly monitor the air pressure, or at least control it once a year at the beginning of the summer season. It is important that this pressure is constant, but if it decreases slightly over the winter, it can always be raised with a conventional car pump to the required level.

All these simple operations will not take much time, it is enough to pay attention to them once a year, especially since everything will pay off with a long and uninterrupted operation of the entire water supply system as a whole.

Pressure switch for accumulator: installation and configuration information

When providing the building with water from a well or a well, a hydraulic accumulator is installed without fail, which is a container of a suitable volume. It is usually used in conjunction with a special pressure switch. For a hydraulic accumulator, it is a control device that allows you to reduce the number of pump cycles.

The main components of a pumping unit with a hydraulic accumulator

Working elements of the device and functioning

From the point of view of design features, the relay is a small unit equipped with special springs. The first of them defines the limit of maximum pressure, and the second defines the minimum. Adjustment is made by means of the auxiliary nuts placed in the case.

Familiarization with the internal structure of the device

The working springs are connected to the membrane, which reacts to pressure surges in one way or another. Exceeding the maximum values leads to compression of the metal spiral, and a decrease leads to stretching. Thanks to such a device, in the contact group, contacts are closed and opened at a certain moment.

The location of the device in the general scheme

The principle of operation of the pressure switch for the accumulator is as follows. Water enters the membrane tank until it is completely filled, which leads to an increase in pressure. When the maximum allowable level is reached, the pump stops pumping liquid.

As water flows, the pressure in the system drops. When the lower level is overcome, the equipment will turn on again. The cycles of switching on and off are repeated over and over again until the elements of the system are in working condition.

Connection diagram with a drain valve in the system

Typically, a relay consists of the following elements:

plastic cases;
rubber membrane;
brass piston;
membrane cover;
threaded studs;
metal plate;
couplings for cable fastening;
blocks for terminals;
articulated platform;
adjusting springs;
contact node.

A manometer can be used to visually determine the pressure

Addition! When working on the moving part of the platform, adjusting springs press against the force created by the piston. Turning the pump on and off depends on the degree of their compression.

Optimal pressure inside the hydraulic tank

Any accumulator inside has a rubber membrane that divides the space into two chambers. One contains water and the other contains compressed air. Thanks to this structure, it is possible to create the necessary pressure when filling and emptying the rubber container.

The device of the hydraulic accumulator is clearly shown

To extend the life of the device, you need to know what pressure should be in the accumulator. It largely depends on the indicators set to turn on the pump. The pressure inside the tank should be about 10 percent less.

Tank pressure check

For example, if the switch-on is set to 2.5 bar and the switch-off is set to 3.5 bar, then the air pressure inside the tank should be set to 2.3 bar. Ready-made pumping stations usually do not require additional adjustment.

Carrying out work on connecting and setting up a pressure switch for a hydraulic accumulator

Although many people find the process of mounting and adjusting the instrument difficult to understand, in fact it is not. Each owner of a country house with a well or a well can independently connect and configure a device to provide the building with water.

One of the schemes for connecting the accumulator to the system

Standard scheme for connecting a pressure switch to a hydraulic accumulator

The finished product interacts with both the plumbing and electrical systems of the building. When closing and opening contacts, liquid is supplied or blocked. The pressure device is installed permanently, since there is no need to move it from place to place.

The purpose of the contact groups of the device is indicated

For connection, it is recommended to allocate a separate power line. Directly from the shield should be a cable with a copper core section of 2.5 square meters. mm. It is not recommended to connect wires without grounding, because the combination of water and electricity is fraught with hidden danger.

Visual diagram for independent connection of the relay

Cables should be passed through the holes located on the plastic case, and then connected to the terminal block. It contains terminals for phase and zero, ground. wires for the pump.

Note! Electrical work must be carried out in a disconnected state from the network. When installing, you must not neglect the observance of the general rules of technical safety.

Correct setting of the accumulator pressure switch

To adjust the device, an accurate pressure gauge is required to determine the pressure without errors. Focusing on its readings, you can make a relatively quick adjustment. By turning the nuts located on the springs, you can reduce or increase the pressure. During setup, you must follow a certain sequence of actions.

Work is underway to set up the device

So, the adjustment of the pressure switch for the accumulator is carried out as follows.

The system turns on, after which, using a pressure gauge, the indicators are monitored at which the device is turned on and off;
First, the lower level spring, which is large, is adjusted. For adjustment, a regular wrench is used.
The set threshold is being tested. If necessary, the previous paragraph is repeated.
Next, the nut is turned for the spring, which allows you to set the upper pressure level. It has a smaller size.
The operation of the system is fully tested. If for some reason the results are not satisfactory, then a reconfiguration is performed.

The adjusting nuts of the device are shown

Note! Before you set up the accumulator pressure switch, you need to remember a simple truth. The minimum allowable difference between the maximum and minimum value should not be less than 1 atmosphere.

The cost of relays and accumulators of some manufacturers

Relay models can be purchased relatively inexpensively. Usually the cost of products does not exceed one thousand rubles. However, electronic counterparts may have a higher price, as they allow for more precise tuning. The table shows the models of some manufacturers and their cost.

Presented pressure switch Gileks RDM-5

Note! On average, for a family of 4-8 people, as a rule, a hydraulic accumulator with a capacity of 50 liters is enough. With a smaller number of people living, a capacity of 24 liters is purchased, and with a larger number - 100 liters.

Hydraulic accumulator Gileks, containing 24 liters

Summarizing

Since the hydraulic accumulator is not capable of functioning without a pressure switch, which is a control device, special attention was paid to the installation and configuration of this particular device. With proper adjustment of the product, it is quite possible to extend the operational period of the main equipment.

We offer for sale modern automation units for pumps manufactured by Gileks. Before you buy an automatic device, we suggest that you familiarize yourself with its characteristics.

The automation unit (automatic device) allows you to automate the operation of the electric pump, start it when the pressure drops (when the tap is opened) and stop it when the water flow in the water supply system stops (when the tap is closed). In addition, the automation unit provides protection for the pump from running without water (“dry running”).

The automation unit is designed for pumping clean water that does not contain solid particles. In the presence of solid particles, it is necessary to install a filter at the inlet to the automation unit. The presence of a pressure gauge provides visual control of the pressure in the water supply system.

Operating principle

The automation unit starts the electric pump within 20-25 seconds after connecting to the mains. Subsequent starts of the electric pump occur when the starting pressure is reached, under the influence of opening the valve. In contrast to systems with a pressure-tank switch, the condition for stopping the electric pump is not dictated by the achievement of a certain pressure in the system, but is determined by a decrease in flow to minimum values. As soon as the automation unit detects this condition, it stops the electric pump with a delay of 7 + 15 seconds, the timing logic is aimed at reducing the frequency of operation of the electric pump in low flow conditions.

The automation unit can be used in conjunction with the pressure switch RDM-5

Mounting

1. The pressure gauge can be mounted on one of the two sides of the automation unit, using an O-ring and two mounting screws. Having chosen a convenient position for the pressure gauge, plug the hole on the opposite side with a screw without using any seal. Install the automation unit in a strictly vertical position at any point located between the pump supply and the first tap (faucet) in such a way that the inlet (male thread 1 ″) is connected to the direction of the water flow from the pump, and the side outlet (male thread 1″) corresponded to the direction of flow in the pipeline. Make sure the hydraulic connections are completely tight. In case of using an electric pump with a maximum pressure of more than 10 bar, it is necessary to install a pressure reducer at the inlet to the automation unit.

2. Follow the wiring diagram on the circuit board cover for the electrical connection. When using an automation unit with three-phase or single-phase electric pumps with a switching current of more than 10 A, use an electromagnetic starter. It is necessary to use an electrical cable with a thermal resistance of at least 99°C.

3. Starting set pressure is set to 1.5 bar, which is the optimum value for most applications. This value can be changed using the adjusting screw located on the top of the automation unit marked "+" and "-".

Starting the automation unit

ATTENTION: If the level of water to be filled is lower than the level at which the pump is installed, it is mandatory to use a foot check valve on the suction pipe.

1. Before commissioning, completely fill the suction pipe and the electric pump with water and start the latter, thereby supplying power to the “NETWORK” automation unit. After stopping the electric pump, open the valve located at the highest point.

2. The installation is correct if the electric pump runs continuously and there is a regular flow of water at the outlet of the faucet. If there is no water flow, it is possible to extend the operation of the electric pump by holding down the "RESET" button for a period longer than the timing of the automation unit. If, in this case, there is no flow, turn off the power to the electric pump and repeat the procedure starting from point 1.

Dry code protection

The red indicator "PROTECTION" lights up when the electric pump is turned off, signaling the danger of dry running. After making sure that the suction line is filled with water, start the electric pump by pressing the "RESET" button.

The device and principle of operation of automation for the pump

There are various means of automation for pumps, among which there are dry-running blockers, water pressure switches, electronic components, sensors, etc. As a rule, electronics operate in conjunction with additional equipment (hydraulic accumulator, float switch, etc.). In this case, the adjustment of the operation of the pumping group can be performed both in terms of pressure and flow. An important constituent element is a pressure gauge that provides visual control of the parameters of the water supply network.

Today, there are several generations of automation for pumps. The latest electronic devices are considered the most efficient due to high-tech equipment, advanced functionality and finer settings.

General working principle:

when the pressure drops, the unit independently starts the pumping unit (in particular, this happens when the valves are opened);
in the absence of water flow, the electric pump is turned off (all taps are closed);
automatic shutdown of the pump group can also occur if the liquid flow is not high enough (protection against "dry running").

What functions does the device perform?

In private houses where there is no running water, the issue of providing drinking quality water is solved in 2 ways:

installation of a tank or arrangement of a pool filled with imported water;
drilling a well to an aquifer.

Water is supplied to the house using a pump of the required power. But the magnitude of the water pressure during its operation is too high to connect the pump unit to the internal water supply networks directly. Therefore, an intermediate tank with a membrane is installed in the house - a hydraulic accumulator, and the required pressure in the network is maintained by the RDM 5 pressure switch. The device allows you to automate the process of water supply in autonomous water supply systems.

Operating principle

The device consists of a brass body with fittings for connecting to the water supply network, spring valves and an electric relay. Outside, the elements are covered with a plastic cover. The scheme of operation of the pressure switch RDM 5 is as follows:

The manufacturer sets the device to the lowest pressure limit of 1.4 bar, the highest - 2.8 bar. When the pressure in the accumulator is less than the lower limit, the relay contacts are closed, and the pump pumps water into the intermediate membrane tank.
When the pressure has risen to the upper limit (2.8 bar), the spring valve is activated and opens the relay contacts. The water supply is stopped.
When a water intake appears in the house, the accumulator starts to empty, the pressure decreases, and when the lower threshold of 1.4 bar is reached, the relay contacts close again and the pump resumes its operation.

As a rule, the RDM 5 device is equipped with ready-made pumping stations, consisting of a pump, a water accumulator tank and the control relay itself. The station is set up at the factory and is completely ready for operation, all that remains is to connect it to the pipe and the mains. But finished products are not suitable for everyone for the following reasons:

the capacity of the accumulator is insufficient;
the pressure of the standard pump is small to ensure the supply of water to the required height;
a downhole pump is used, lowered into the well.

In these cases, the automatic water supply system will have to be assembled from separate elements, and the pressure switch will have to be adjusted accordingly, coordinating its operation with the storage tank. Before purchasing and connecting the device, it is recommended to study its technical characteristics:

pressure control range in the water supply system - from 1 to 4.6 bar;
ambient temperature range — from 0 to +40 °С;
minimum pressure drop - 1 bar;
supply voltage - 220 V;
fitting diameter - DN 15, connection - G ¼''.

If for some of the technical characteristics of the RDM 5 relay does not suit you, then you will have to look for another regulator. But practice shows that the parameters of this device meet the requirements of the vast majority of autonomous water supply systems.

How to adjust the device?

The pressure switch is set up after the installation of the internal and external water supply network of the house and connection to the electrical network.

Connections of external and internal pipelines must be checked by tests so that subsequent leaks do not interfere with the adjustment process. Due to leaky joints, the pressure before or after the pump will spontaneously decrease, which will also affect the operation of the relay.

Before setting, determine the required head pressure. To supply water to all points of water intake located on different floors, it is necessary to provide the necessary pressure in the accumulator. The efforts of the tank membrane should be enough to push the entire volume of water to the required height and overcome all local resistances. At home, this pressure value is most often determined experimentally.

The calculation is simple: 1 m of lifting height is equal to 10 m of horizontal section and corresponds to a pressure of 0.1 bar. The farthest branch of the water supply is taken into account. Having roughly determined the required pressure, it is necessary to create such pressure from the air chamber of the accumulator. To do this, remove the plastic cap from the spool (usually located at the end of the tank) and pump up the air chamber with a conventional automobile pump, controlling the pressure with a pressure gauge.

Without connecting the branch pipe of the internal water supply network, check how the relay works in conjunction with the pump at the factory settings. At the same time, check the tightness of the outer pipeline.
Remove the plastic relay cover covering the adjusting screws.
The large screw regulates the upper limit (pump shutdown), the small screw regulates the pressure drop. Adjust the lower limit so that its value is 0.2 bar more than you pumped into the accumulator.
To reach the exact values, you will have to adjust several times by opening the taps of the mixers and releasing water from the battery. At the same time, record the pressure gauge readings when the pump is turned off and on and correct them with adjusting screws.

As a result of the settings, the difference between the lower and upper limits should not be less than 1 bar. Practice shows that the optimal pressure drop is about 1.5 bar, then the pump will not turn on too often. At the end of the adjustment, do not rush to put the cover back in place, follow the operation of the system for 1 day. It may need a little adjustment.

Principle of operation

Despite the fact that the relay regulates the pressure of the water pressure, its mechanisms include electrical components. Under water pressure, two contacts are closed, so the connection to the mains is carried out:

when the pressure is below the set upper pressure limit, the relay contacts remain closed, the pump continues to pump water;
when the pressure exceeds the upper pressure limit, the contacts open, the pump stops working.

The principle of operation is not complicated, but consumers have some difficulties when adjusting the pressure switch, setting the lower and upper limits.

Adjustment Method

The setting of the pressure switch by the manufacturers in the factories is not always accurate or not suitable for local operating conditions. But the design is made in such a way that each owner adjusts the necessary parameters without any problems. In private houses, pumps at the water supply point in front of the accumulator must create a head pressure of at least 1.4 atmospheres. Otherwise, the adjustment does not make sense, the contacts will not close and the pump will not turn on. There must be a pressure gauge at the connection point, according to its readings, the pressure value is judged:

We connect the pressure switch to the receiving point, as required by the instructions, the accumulator is not connected, a plug is installed instead. The pump is connected to the network - this way the operation of the relay is checked at the factory settings and the tightness of the network to the relay.
Record the pressure gauge readings (3 atmospheres).
Remove the housing cover from the relay.

Screws for adjusting the pressure limits under the housing cover

Under the housing cover there are large and small nuts with springs, when the large nut is rotated clockwise, the fixing spring is compressed, the upper limit increases. The upper limit is reduced by turning the large nut counterclockwise.

Adjust the pump shutdown moment with a large nut, the best option is 2.5–3 atmospheres, take 2.8.

Check the pressure in the accumulator, it should have a separate pressure gauge, let's assume that it is 1.5 atm. Connect the expansion tank to the relay.

Open the tap at the highest point of the water supply, if the pressure is not enough, pump up the bicycle pump in the expansion tank to the desired pressure.
Having opened the water, observe at what value of the pressure gauge the relay will turn on the pump. Record the lower limit reading when the pump turns on with a drop in head. Let's assume that this value will be 1 atmosphere.
2.8–1 - the difference between the lower and upper limits will be 1.8 atm., This is 0.3 atmospheres more than the pressure in the expansion tank.

The operating manual specifies that the pressure of the lower limit should ideally be 0.2 atmospheres higher than the pressure in the expansion tank. With this installation ratio, the number of starts for the electric pump is optimal, which significantly extends the service life of the pump and relay. The difference can be corrected with a small bolt with a spring or by changing the pressure in the accumulator, pump or bleed air. Properly installed pressure switches RDM 5 "Dzhileks" will make the pump mode more economical, reduce power consumption and last a long time.

/ Automation unit for the pump

We offer for sale modern automation units for pumps manufactured by Gileks. Before you buy an automatic device, we suggest that you familiarize yourself with its characteristics.

Operating principle

The automation unit can be used in conjunction with

Mounting

1. The pressure gauge can be mounted on one of the two sides of the automation unit, using an O-ring and two mounting screws. Having chosen a convenient position for the pressure gauge, plug the hole on the opposite side with a screw without using any seal. Install the automation unit in a strictly vertical position at any point located between the pump supply and the first point of water intake (faucet) so that the inlet (male thread 1") is connected to the direction of the water flow from the pump, and the side outlet (male thread 1") corresponded to the direction of flow in the pipeline. Make sure the hydraulic connections are completely tight. In case of using an electric pump with a maximum pressure of more than 10 bar, it is necessary to install a pressure reducer at the inlet to the automation unit.

Starting the automation unit

ATTENTION: If the level of water to be filled is lower than the level at which the pump is installed, it is mandatory to use a foot check valve on the suction pipe.

Correct installation of the device

First of all, if a modification without measuring instruments is purchased, you should purchase a pressure gauge and install it on the side panel. The mechanism is necessary to control and manage the block.
The automatic device itself crashes into the water supply line in the area between the water consumption point (faucet) and the pumping device. The unit is installed exclusively in a vertical position, with the blue metal cover up. In this case, the inlet of the device (indicated in the instructions) should be located on the side of the pump outlet. The outlet port conducts the water further into the supply line.
After the control apparatus is mounted in line, it is necessary to carefully inspect all joints and connections for tightness. If errors are found during installation, they should be sealed with sealant or connecting elements.
The unit is connected to the network strictly according to the scheme specified in the instructions. Moreover, if the device is equipped with a pump with a current of more than 10 amperes, a magnetic starter is additionally installed. The main requirement for the electrical cable used with the device is increased resistance to high temperatures.

If necessary, the supply line is supplemented with filters for water purification and a receiver for equalizing pressure in the system.

After the device is turned off, it is necessary to open one of the taps (if there are multilevel ones, then preferably the top one). There are two options for this:

In the first case, water will flow from the tap in a continuous, uninterrupted flow. The unit turns on, and the pumping device works throughout the entire period of use of the crane. In this case, the installation of the device is correct.
If the water flow is not stable or does not exist at all, you can try to restart the device with the "Restart" button. The button is pressed and held until the pumping device works. If nothing has changed in this case, a thorough inspection of the device and the entire line is carried out, and if necessary, dismantling and adjustment.

Pump units compatible with the unit

The device works most effectively in combination with pumping devices that meet the following characteristics:

current strength in the range of 6-10 A;
device productivity up to 100 l/min;
voltage not higher than 250 V;
the maximum temperature limit of the pumped liquid is 75 degrees;
connection to a pipe with a section of 1 inch.

Gileks automation is multifunctional, easy to set up and install, and affordable. It can work with both native pumps and pumps from other manufacturers to automate the water supply.

The company offers reliable and modern options for automation for the pump, which have a long service life and good performance. Let's take a closer look.

Total pump automation

How it works?

As soon as the pressure level drops to the minimum allowable rate, the control element of the automation will turn off the pump. So the safety and performance of the device is significantly extended.

Installation

To automate the control of the pump, you need to purchase the appropriate additional components for it (depending on your needs), and connect them in the following sequence:

The pressure gauge is attached to the automatic unit from the side using the fasteners included in the kit. Which side to mount - "a matter of discretion." But, it is important to carefully fix the device on the panel, without using sealing elements.
The automation unit is mounted exclusively in a vertical position. It can also be fixed in any convenient place, but on the segment between the tap (the first water intake point) and the pump supply system. Moreover, it must be done in such a way that the outer inlet of the system is adjacent to the water outlet channel from the pump, and the side outlet is adjacent to the water flow in the pipe.
All connections must be tightly fixed. It is worth making sure that they are tight and double-check the correct connection of all connecting elements.
If automatic equipment is used for electric pumping systems with a maximum pressure threshold of 15 bar, then a pressure reducer is mounted at the input of the automation.
The body of the device (or circuit board) contains the electrical circuit for connecting the automation. Strictly follow it when connecting! If a single or three-phase pump with an operating current of more than 10 amperes is used, the automation must be connected through an electromagnetic starter. The cable used to connect the device must be resistant to elevated temperatures (above 100 degrees) and non-flammable.
Automatic adjustment and operation of systems (minimum pressure) is designed for a pressure of 2 atm. This option is the most common and optimal for most systems. But, this parameter can be easily adjusted if necessary. This is done by rotating the crane, which is located on top of the automatic system, and has plus and minus markers.

Starting the automatic system

Important! When the level of incoming water is lower than the level at which the pumping system is mounted, it is imperative to install a bottom check valve on the inlet pipe.

We start the automation as follows:

Immediately before turning on the device, we completely fill the inlet pipe of the pump with water and start it (the "Network" LED should light up). This manipulation will turn on the automation unit. As soon as the pump starts to work and, after a while, stops, you need to open the outlet valve, which is located at the highest point.
If the pump runs all the time with the tap open, and provides a continuous flow of water, the installation is considered correct. The lack of water flow indicates that you need to hold down the "Restart" button and keep it for the duration of the automatic system. If the flow is still missing during such manipulation, you need to repeat the launch.

Idle protection

When the “Protection” LED lights up on the automation unit, and the pump itself is turned off, this may indicate the danger of idle operation of the system. This is how press control works.

Recheck all systems again. If everything is in order - let the water out of the incoming system, and fill it again. Then press the "Reboot" button.to the menu

Optimal characteristics of automation for pumps

Vibrating or any other type of pump can be additionally equipped with automation systems. But, they have different parameters, properties, etc. Which ones are worth buying?

Technical indicators (optimal):

Operating voltage = 210-250 V;
Frequency = 40/70 Hz;
Minimum working pressure = 1-4 atm.;
Load current = 6-10 A;
Water flow rate = 70-100 l/min;
Upper pressure threshold = 15 atm.;
Maximum water temperature = 75 degrees;
Inlet pipe diameter = 1 inch;
Degree of protection = 1P65.

What do you need to know?

Important! The valve located on the pipe section between the automatic / pumping systems, and the valve running on the outlet pipe of the automatic unit, are the culprits in equipment malfunctions.

The maximum working pressure is not regulated by automation. It corresponds to the indicator of the electric pump.

Features of the operation of hydraulic accumulators Gileks - Click!

In the modern world, not a single water supply system for private houses is designed without a hydraulic tank - a hydraulic accumulator or an expansion tank.

Functions

The main functions that an expansion or hydraulic tank performs are:

Increasing the working life of the electromechanisms of the pumping station. During operation, the need for very frequent switching on and off of the pump is reduced, which significantly extends its service life.
Elimination of possible hydraulic shocks in an autonomous water supply system. An increase or decrease in the pressure (pressure) of water in the system negatively affects all the nodes and details of an individual water supply system. The hydraulic accumulator successfully stabilizes the pressure in the water supply and prevents the formation of gaps and leaks.
Accumulation (or accumulation) of water under a certain pressure. This feature is very useful in case of frequent power outages or low water pressure.

Please note: horizontal accumulators are used mainly for surface pumps, and small devices with a capacity of up to 24 liters are ideal for low-power pumping equipment (no more than 1 kW).

Device

Gileks hydraulic accumulators - both horizontal and vertical in their structure have:

steel welded vessel on special legs;
flange made of galvanized steel with a threaded fitting;
butyl rubber replaceable membrane located inside the container;
air valve with cap and plastic cap;
counterflange.

The horizontal model is additionally equipped with a special platform with fasteners for installing the pump.

Specialist note: the pressure in the tank must be at least 1.5 atmospheres, and the higher this figure, the greater the water pressure in the system.

Connection options

There are several schemes for connecting the Gileks accumulator:

Connection to the deep pump. The expansion tank is located after the pump, which makes it possible to reduce the frequency of switching on and off the unit. After all, this figure is about 5 - 20 inclusions per minute, which accelerates the process of wear of the rubbing parts of the pump.
With storage water heater. In this scheme, the hydraulic tank is placed before the water heater, compensating for the thermal expansion of water in the boiler. At the same time, the higher the temperature and pressure of water, the larger the volume of the expansion tank should be.
With pressure booster pump. The hydraulic accumulator is mounted at the pump inlet, compensating for the drop in water pressure in the system at the time of its start.

It is important to know: the first filling of the hydraulic tank tank should be done with a small pressure of water so as not to damage the walls compressed by internal pressure.

At the first start, you should act slowly and deliberately - this will avoid the appearance of leaks and equipment failure.

When choosing a hydraulic accumulator Gileks, first of all, you should calculate the required volume of the tank.

To do this, you need to know the approximate amount of water that is consumed during the day by the family.

It is imperative to take into account the materials from which the main components and the structure itself are made, since the service life of the hydraulic tank directly depends on this.

It should be noted that Gileks accumulators are rapidly gaining popularity among consumers. This is evidenced by numerous reviews, which talk not only about the reliability, durability and functionality of these models.

Attractive appearance, ease of installation and ease of operation also play a significant role when choosing Gileks hydraulic tanks.

To cope with the variable water pressure, which causes a lot of trouble for the inhabitants of a private house, a hydraulic accumulator for water supply systems is called upon.

A hydraulic accumulator is a special device, without which the hot and cold water supply scheme of a private house has flaws.

It is possible that you have not come across this word before, but the term "expansion tank" is familiar to almost everyone.

The principle of its installation and the connection process in heating for a private dwelling is best considered separately, but we will focus on the hot and cold water supply system.

The use of batteries in the water supply of the private sector is always relevant - whether water is used from a personal well or a pumping station is responsible for its supply.

History reference

The prototype of a hydraulic accumulator is a water tower.

Of course, it cannot eliminate water hammer, but as an auxiliary station that optimizes the pressure in the water supply system, it is still used in some cases to this day.

During low drawdown hours, the station fills the volume of the tower with water using pumps, and during peak hours, this reserve reduces the load experienced by the station.

The same principle is now working in a hydraulic accumulator, which is very necessary in the automatic water supply system of private houses.

Purpose, types and design of hydraulic accumulators

The answer to the question: "Why do we need a hydraulic accumulator?" - very simple. A detailed lecture on this is presented to you in the video.

Hydraulic accumulators, which are used to supply water to a private house, perform three tasks:

Create the necessary pressure in the internal water supply networks of the house;
They play the role of storage of water reserves, which is very useful in case of failure of the power supply system, or if the pumping station stops supplying;
Due to their design, they significantly reduce the likelihood of water hammer in the networks of a private house.

A hydraulic accumulator is a device in the form of a metal tank, supplemented by a mechanism that creates water pressure inside it.

Subject to all connection conditions, installation of the battery and its maintenance can be done by hand.

The most common device that uses the principle of operation on the energy of compressed air. It is equipped with a partition - a rubber pear or a rubber membrane.
