Automation Gileks (block) for the pump: adjustment

Content

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 pumps from dry running and saves energy consumption. This approach allows you to extend the life of expensive pumping equipment.

A special feature of automation from the Gilex 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 Gilex automation unit. Such a device is connected directly to the pumping apparatus and responds to the pressure level in the system.

The Gilex 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 decreases. For external monitoring of device operation in lateral surface There is a pressure gauge built into the unit.

The device is designed to operate on the basis of a pumping station or other surface pump pumping clean water. Use with a low content of abrasive impurities is also possible, but in this case the device is equipped with an additional filter.to menu

Operating principle of the device

Gileks automation operates autonomously from the regular electrical network. After 30 seconds have passed after installing and connecting the unit, it turns on and works within a few seconds. Then the device turns off and is activated only if the pressure in the line changes.

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 device pumps water until the pressure equalizes again (when the tap closes). After the tap is turned off, the device operates for another 5-20 seconds, continuing to pump water into the line. This measure is a precaution in case the pressure in the system drops below normal and the device is not able to monitor the pressure level.to menu

Correct installation of the device

Automation Gilex 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 automation unit Press control from Gilex is carried out in next order:

First of all, if you purchased a modification without measuring instruments, you should purchase a pressure gauge and install it on the side panel. The mechanism is necessary to monitor and control the unit.
Myself automatic device crashes into the water main in the area between the point of water consumption (tap) and the pumping device. The unit is installed exclusively in a vertical position, with the blue metal cover facing up. In this case, the inlet of the device (indicated in the instructions) should be located on the outlet side of the pump. The outlet conducts the water further into the supply line.
After the control device is installed in the line, it is necessary to carefully inspect all joints and connections for leaks. 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 diagram 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 to equalize the pressure in the system.

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

After the device is turned off, you need to open one of the taps (if there are multi-level taps, then preferably the top one). There are two options:

In the first case the water will flow from the tap in a continuous, uninterrupted flow. The unit turns on and the pumping device operates throughout the entire period of use of the tap. In this case, the device was installed correctly.
If the water flow is not stable or absent at all, you can try to restart the device using the “Restart” button. The button is pressed and held until the pumping device operates. If in this case nothing has changed, thorough examination device and the entire line, and, if necessary, dismantling and adjustment.

Pumping units compatible with the unit

Automation from Gilex is a universal device. With its help, the operation of pumping devices can be regulated from various manufacturers. Regarding the principle of operation, such a mechanism for equalizing pressure is installed on a vibration, centrifugal, vortex, or screw pump.

The device works most efficiently when combined 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 cross-section of 1 inch.

Other automatic options Gilex

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

Gilex Crab consists of the following components:

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

The device operates on the basis of a standard 220 V electrical network. Suitable for simultaneous connection of 2-3 water intake points. An adjustable relay allows you to set the pressure level that the device will maintain before starting work. Like the previous type of device, Krab 50 is a universal device and is suitable for connection to well pumps of any manufacturer.to menu

Pressure switch RDM-5

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

The operating principle of the device is as follows. The device responds to the pressure level 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 apparatus is interrupted and it turns off.

The minimum and maximum values at which the pumping device is activated are set by the user. They can be adjusted using two nuts that fix the degree of spring tension. The larger nut, when rotated counterclockwise, sets the maximum pressure reading; the smaller nut, when rotated, allows you to adjust the difference between the maximum and minimum readings.

RDM-5 is designed for use exclusively in water. The operating voltage for the device is 220-230 V. The temperature of the pumped liquid is 0-40 degrees. The relay is fixed to a ¼-inch pipeline. A prerequisite for using RDM-5 is high-quality grounding.to menu

Float switch Gilex

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

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 switch lever and a ball that changes the position of the lever. Based on 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.

Models with three wires support the ability to turn on the pick-up point in the extreme upper and extreme lower positions. 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 Gileks (pump control unit)

Content

Gilex automation is multifunctional, easy to configure and install, and affordable. It can work with both native pumps and pumps from other manufacturers to automate water supply.

The company offers reliable and modern options automation for pumps with a long service life and good characteristics. Let's take a closer look.

Total pump automation

Gilex Crab automation unit is a device that automates the operation of an electric pump. It turns on the system when the pressure decreases (the valve opens), and turns it off when the flow stops (the valve closes). Automation also consists of protecting the pumping station when it is “idle” - operating without water, on “dry running”.

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

How does this work?

The automatic unit Gilex 9001 turns on 30 seconds after connecting to the power supply. It then turns off and goes into sleep mode. Further activation of the device occurs when the pressure changes - the valve opens and closes.

As soon as the pressure level drops to the minimum permissible norm, the automation control element will turn off the pump. This significantly extends the safety and performance of the device.

After reducing the pressure to minimum permissible 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, when weak pressure water, it systematically did not turn off. This allows you to extend the life of the system.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 on the side using the fasteners included in the kit. Which side to mount on is “a matter of discretion.” But, it is important to carefully secure the device to 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 in the section between the tap (the first water intake point) and the pump supply system. Moreover, this must be done so that the external 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-checking that all connecting elements are connected correctly.
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 automation input.
The device body (or circuit board) contains an electrical circuit for connecting the automation. Follow it strictly when connecting! If a single or three-phase pump with an operating current of more than 10 Amps is used, the automatic mandatory connected via 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 the activation of the 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 tap located on top automatic system, and has plus and minus markers.

to menu

Starting the automatic system

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

We start the automation as follows:

Immediately before turning on the device, 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 working and stops after a while, 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 absence of water flow indicates that you need to hold down the “Restart” button and hold it for as long as the automatic system operates. If after such manipulation the flow is still missing, you need to repeat the launch.

Idling protection

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

Recheck all systems. If everything is in order, drain the water from the incoming system and refill it. Then click the “Reboot” button.to the menu

Optimal automation characteristics for pumps

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

Technical indicators (optimal):

Operating voltage = 210-250 V;
Frequency = 40/70 Hz;
Minimum operating pressure = 1-4 atm.;
Load current = 6-10 A;
Water flow speed = 70-100 l/min;
Upper pressure threshold = 15 atm;
Limit 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 section of pipe between the automatic/pumping systems and the valve running on the outlet pipe of the automatic unit are the culprits of equipment malfunctions.

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

The maximum operating pressure is not automatically regulated. It corresponds to the indicator of the electric pump.

Features of operation of Gilex hydraulic accumulators - 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. In this article we will talk about the purpose of Gilex hydraulic tanks, their design, installation features, types and secrets of the right choice.

Functions

The main functions performed by the expansion or hydraulic tank are:

Increasing the working life of the electric mechanisms 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 water hammer in autonomous water supply. An increase or decrease in water pressure (pressure) in the system negatively affects all components and parts of an individual water supply system. The hydraulic accumulator successfully stabilizes the pressure in the water supply and prevents the formation of ruptures and leaks.
Accumulation (or accumulation) of water under a certain pressure. This function is very useful when there are frequent power outages or low water pressure.

Please note: horizontal hydraulic 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

Hydraulic accumulators Gilex - both horizontal and vertical in their structure have:

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

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

Specialist's 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 connection diagrams for the Gilex hydraulic accumulator:

Connection to a deep-well 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 indicator is about 5 - 20 starts 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 the water, the larger the volume of the expansion tank.
With pump to increase pressure. The hydraulic accumulator is mounted at the pump inlet, compensating for the drop in water pressure in the system at the time of its startup.

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

When starting up for the first time, you should act slowly and deliberately - this will avoid leaks and equipment failure.

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

To do this you need to know approximate quantity water, which is consumed by the family during the day.

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 Gilex hydraulic 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 Gilex hydraulic tanks.

A hydraulic accumulator for water supply systems is designed to cope with variable water pressure, which causes a lot of trouble for residents of a private house.

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

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 residential space are 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.

There are a number of models of hydraulic accumulators on the Russian market, and buyers more often choose the domestic model “Dzhileks”, which combines reliable operation and convenient price segment, what can't be said about imported analogues.

Historical background

The prototype of a hydraulic accumulator is a water tower.

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

During low water withdrawal hours, the station fills the tower volume with water using pumps, and during peak hours, this supply reduces the loads experienced by the station.

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

Purpose, types and design of hydraulic accumulators

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

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

Create the necessary pressure in the internal water supply networks of the house;
They act as a storage facility for water reserves, which is very useful when the power supply system fails, or if the pumping station stops supplying;
Due to their design, they significantly reduce the likelihood of water hammer occurring in the networks of a private home.

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

If all connection conditions are met, battery installation and maintenance can be done with your own hands.

The most common device is one that uses compressed air energy. It is equipped with a partition - a rubber bulb or rubber membrane.

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

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

When water collection begins, the energy of compressed air, using pressure, pushes water out of the accumulator into internal networks Houses.

When the pressure decreases, the automation is activated, the pumps are turned on, and water is pumped into the tank until the stop signal from the first sensor.

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

Air pressure is regulated by a hand or automobile pump, this easy setup is another factor influencing the choice in favor of Gilex.

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

The spring device is distinguished by its low price and simplicity of design; its disadvantages include its small working volume.

Truck units are also considered simple, inexpensive units, but they have a longer list of disadvantages: difficulty in installing them yourself, large sizes, low operating pressure, significant energy consumption, and complex adjustment principles.

Depending on the type of design, batteries can be open or closed type.

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

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

Hydraulic accumulators "Dzhileks" are manufactured in horizontal and vertical options, the principle and installation scheme of which differ - vertical ones take up less space during installation, and horizontal ones require a special platform for installation and connection.

The coloring of batteries (red and blue) uses the generally accepted coloring of water supply system pipelines.

Blue (for cold water) differ from the Reds in that they rely on more high blood pressure, and they use food grade rubber.

If you are the owner of a country house, then doing your own calculations of the water supply system, you will probably have to think about buying a hydraulic accumulator. And this will entail a number of questions.

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

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

You should also calculate the tank volume before purchasing.

How to choose a size?

It has been experimentally 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 can perform the calculation yourself and select a battery for a private home that suits your needs.

The key points will be the performance of the pumps and the volume of peak water withdrawal.

The volume of water in the tank should ensure that the pump pumps water no more than 30 times per minute.

When determining the size of the hydraulic accumulator itself, you need to take into account that the water in it will occupy approximately one-third to one-half of the total volume of the installation.

The video below describes the structure of the hydraulic accumulator and why it is needed.

Tanks with a small volume are less effective at combating water hammer, however, too much water can lead to stagnation inside the tank.

Installation of a hydraulic accumulator large size must be done on a reliable foundation that can support the weight and volume of water stored in the tank.

You can choose which battery is right for you by yourself by performing the necessary calculations and reading the technical documentation, or by contacting specialists.

Secrets of installation and adjustment

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

The connection diagram using the example of a Gilex battery is shown in the figure below.

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

To carry out maintenance and repairs, it is necessary to discharge water from the tank; this point must also be provided for connecting the device to a 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 included with each product.

Do not refuse to study this important document in advance - this will allow you to avoid possible alterations after installation is completed and guarantee the service life promised by the factory.

Setting up a hydraulic accumulator installed in an automatic water supply system is quite simple. For example, let's take the Gilex membrane battery.

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

To correctly adjust the pressure, leave the water discharge open and pump air through the valve located on the tank.

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

Let's close the dump, fill the system with water and bleed air through the spool; if water appears from the spool, it means it's time to change the membrane.

You can replace the membrane yourself, just select original parts for this.

More and more people are making their choice using hydraulic accumulators to supply water to a private home.

A simple connection diagram and setup, the ability to do installation and repair yourself and the use of automatic control of the operation of an individual pump make this device simply irreplaceable.

And if you happen to choose the domestic hydraulic accumulator “Dzhileks”, then you will also receive optimal combination prices and high-quality equipment, which cannot be said about other imported analogues.

Portal about pumps. Automation unit for a submersible, deep-well pump

Content

Automation for a submersible pump is installed to regulate the flow of water and ensure uninterrupted operation in a well or well. Thanks to such a 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 operating principles 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. A deep pump for lowering into a well or deep well operates when immersed up to 50 m. Operation requires water pressure, therefore, depending on the type of model, there are recommendations for immersion.

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

The vibration pump system is popular among technically savvy people; it is more convenient to use and more productive. These pumps clean water and wells; they also work in polluted environments. Therefore, when choosing the equipment necessary for water supply, you should first pay attention to them.

The operating scheme is as follows - under the influence of current, a coil is magnetized, attracting the armature. Because of this, the rubber piston bends, reducing the pressure and 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. Water is pushed into the discharge chamber. When the water retreats from the coil, it is magnetized again and the rubber piston, bending, again creates a pressure difference that pushes water from the discharge chamber into the pipeline.to menu

Pumps with pressure sensor

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

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, acquiring a brass adapter. The thread must be sealed to avoid leakage and breakage.

Connects to the power grid in several stages:

two groups of contacts on the pressure sensor are determined, which open at maximum pressure;
when choosing a cable, be guided by the power of the pump;
the wire serving for grounding is connected to the relay through certain screws. The grounding symbol on the screws is indicated by an inverted T with two additional horizontal stripes;
The conductors of the power supply wire are connected to the contacts of each separate pair of contacts on the pressure sensor. They should not be combined under any circumstances;
The relay contacts are connected to the pump, observing the color of the wires. You can connect them to the ground wires, but this is not necessary.

Checking the operation of the relay: turn on the automatic well pump 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 you use up water (you can turn on the tap or hose), then the pressure drops and, again, at a certain point, the pressure switch turns the pump back on.

Setting up a submersible pump with automation

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

Disconnect the hydraulic system.
Drain the water until the pressure gauge reads zero.
Turn on the electricity in the hydro supply system.
Restart the pump and monitor the pressure increase.
At the moment when the relay turns off the pump, record the pressure on the pressure gauge.
After this, drain the water again until the automatic system turns on the pump.
Record the cut-in pressure.
Clean the filters.

Only after these manipulations do they begin to configure. The relay has two springs. The large one regulates the maximum value, while the small one regulates the difference between the maximum and minimum. To set the maximum pressure value, tighten the large relay spring. If it is necessary to adjust the minimum value, then tighten the nut on the small spring. To reduce the pressure value, the nuts are lowered.

Next, the manipulations are repeated point by point (excluding filter cleaning) to make sure that the system operates in the desired mode. Please note that the nuts are sensitive and must be twisted carefully.to menu

Dry running protection and float switches

Dry running is the name given to the operation of a submersible pump without sufficient water. This occurs due to clogging, leakage of the pipe and lack of water. Having picked up correct model and by calculating the dynamic change in water level, the last problem can be avoided.

Other damage can be avoided by regular inspection and cleaning. There are relays with an additional dry-running protection function. For this purpose, special floats and press controls are produced using automation.

Float switches are suitable for a well or large water tank. Some of them are designed to limit overflow, so you should carefully read 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 switched off (the motor does 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 tap is opened and turns off when the tap is closed. Depending on the settings, it turns off when the pressure drops to 1.5-2.5 bar.k menu

Operating principle of a hydraulic accumulator

This is a tank installed in the system to regulate pressure and store water. Purposes of the hydraulic accumulator:

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

Inside the accumulator tank there is a membrane dividing it into two parts. The first one stores water, the second one stores air or nitrogen. The membrane is made of butyl, rubber material, suitable for hygienic standards for storing water and withstanding significant pressure. Thanks to this material, water does not come into contact with the metal of the tank walls. Some models of hydraulic accumulators are equipped with a valve for bleeding air, while 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. When water is drawn from the tank, the pressure drops and the sensor turns on the automation. The pump with pressure sensor is adjustable. The hydraulic accumulator is connected to the submersible pump control unit.

Aquarobot pumps

Pumping systems and surface pumps Aquarobot are equipped with necessary devices. Therefore, there is no need to buy additional relays, flow sensors and hydraulic accumulators. The aqua robot is automated and configured for different frequency of use; just select a model.

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

Connecting the automation unit to the pump

Self-piping of the automation unit for deep and submersible pumps requires power calculations. Therefore, it is better to purchase equipment from the same company in advance, designed to be connected to 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. Divided:

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

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

The automation control unit for the submersible automation 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 electrical network and the automation unit using fastons. The minimum pressure is adjusted with a screw; as a rule, it is 1.5 bar. For sealing, it is recommended to use Teflon tape.

Operating principle of the device

When the tap at the point of water consumption opens, 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 device pumps water until the pressure equalizes again (when the tap closes). After the tap is turned off, the device operates for another 5-20 seconds, continuing to pump water into the line. This measure is a precaution in case the pressure in the system drops below normal and the device is not able to monitor the pressure level.

Correct installation of the device

Automation Gilex 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 automatic press control unit from Gilex is carried out in the following order:

First of all, if you purchased a modification without measuring instruments, you should purchase a pressure gauge and install it on the side panel. The mechanism is necessary to monitor and control the unit.
The automatic device itself crashes into the water main in the area between the point of water consumption (faucet) and the pumping device. The unit is installed exclusively in a vertical position, with the blue metal cover facing up. In this case, the inlet of the device (indicated in the instructions) should be located on the outlet side of the pump. The outlet conducts the water further into the supply line.
After the control device is installed in the line, it is necessary to carefully inspect all joints and connections for leaks. 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 diagram 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 to equalize the pressure in the system.

After the device is turned off, you need to open one of the taps (if there are multi-level taps, then preferably the top one). There are two options:

In the first case, water will flow from the tap in a continuous, uninterrupted flow. The unit turns on and the pumping device operates throughout the entire period of use of the tap. In this case, the device was installed correctly.
If the water flow is not stable or absent at all, you can try to restart the device using the “Restart” button. The button is pressed and held until the pumping device operates. If in this case nothing has changed, a thorough inspection of the device and the entire line is carried out, and, if necessary, dismantling and adjustment.

Pumping units compatible with the unit

The device works most efficiently when combined 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 cross-section of 1 inch.

Characteristics of the Gilex automation unit

How does this work?

As soon as the pressure level drops to the minimum permissible norm, the automation control element will turn off the pump. This significantly extends the safety and performance of the device.

After the pressure drops to the minimum permissible level, the system will not turn off immediately, but after several tens of seconds (usually from five to twenty, depending on the specific model). A delay in turning off the pumps is necessary so that, with low water pressure, it does not systematically turn off. This allows you to extend the life of the system.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 on the side using the fasteners included in the kit. Which side to mount on is “a matter of discretion.” But, it is important to carefully secure the device to 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 in the section between the tap (the first water intake point) and the pump supply system. Moreover, this must be done so that the external 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-checking that all connecting elements are connected correctly.
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 device body (or circuit board) contains an electrical circuit for connecting the automation. Follow it strictly when connecting! If a single or three-phase pump with an operating current of more than 10 Amps is used, the automation must be connected via 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 tap, which is located on top of the automatic system and has “plus” and “minus” markers.

Starting the automatic system

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

We start the automation as follows:

Immediately before turning on the device, 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 working and stops after a while, 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 absence of water flow indicates that you need to hold down the “Restart” button and hold it for as long as the automatic system operates. If after such manipulation the flow is still missing, you need to repeat the launch.

Idling protection

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

Recheck all systems. If everything is in order, drain the water from the incoming system and refill it. Then click the “Reboot” button.to the menu

Optimal automation characteristics for pumps

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

Automation Gileks in the water supply system

Technical indicators (optimal):

Operating voltage = 210-250 V;
Frequency = 40/70 Hz;
Minimum operating pressure = 1-4 atm.;
Load current = 6-10 A;
Water flow speed = 70-100 l/min;
Upper pressure threshold = 15 atm;
Limit 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 section of pipe between the automatic/pumping systems and the valve running on the outlet pipe of the automatic unit are the culprits of equipment malfunctions.

The minimum operating 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 operating pressure is not automatically regulated. It corresponds to the indicator of the electric pump.

Features of operation of Gilex hydraulic accumulators - 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 performed by the expansion or hydraulic tank are:

Increasing the working life of the electric mechanisms 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 water pressure (pressure) in the system negatively affects all components and parts of an individual water supply system. The hydraulic accumulator successfully stabilizes the pressure in the water supply and prevents the formation of ruptures and leaks.
Accumulation (or accumulation) of water under a certain pressure. This function is very useful when there are frequent power outages or low water pressure.

galvanized steel flange with threaded fitting;
butyl rubber replaceable membrane located inside the container;
air valve with cap and plastic cover;
counter flange.

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

Specialist's 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 connection diagrams for the Gilex hydraulic accumulator:

Connection to a deep-well 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 indicator is about 5 - 20 starts 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 the water, the larger the volume of the expansion tank.
With pump to increase pressure. The hydraulic accumulator is mounted at the pump inlet, compensating for the drop in water pressure in the system at the time of its startup.

A hydraulic accumulator for water supply systems is designed to cope with variable water pressure, which causes a lot of trouble for residents of a private house.

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

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 residential space are 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.

There are a number of models of hydraulic accumulators 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 analogues.

Historical background

The prototype of a hydraulic accumulator is a water tower.

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

During low water withdrawal hours, the station fills the tower volume with water using pumps, and during peak hours, this supply reduces the loads experienced by the station.

The same principle now works 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 you need a hydraulic accumulator?” - very simple. A detailed lecture about this is presented to you on video.

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

Create the necessary pressure in the internal water supply networks of the house;
They act as a storage facility for water reserves, which is very useful when the power supply system fails, or if the pumping station stops supplying;
Due to their design, they significantly reduce the likelihood of water hammer occurring in the networks of a private home.

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

If all connection conditions are met, battery installation and maintenance can be done with your own hands.

The most common device is one that uses compressed air energy. It is equipped with a partition - a rubber bulb or rubber membrane.

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

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

When the pressure decreases, the automation is activated, the pumps are turned on, and water is pumped into the tank until the stop signal from the first sensor.

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

The air pressure is regulated by a manual or automobile pump; this simple setting is another factor influencing the choice in favor of Gilex.

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

The spring device is distinguished by its low price and simplicity of design; its disadvantages include its small working volume.

Depending on the type of design, batteries are of open and closed type.

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

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

Gilex hydraulic accumulators are manufactured in horizontal and vertical versions, the principle and installation diagram of which are different - vertical ones occupy a smaller area during installation, and horizontal ones require a special platform for installation and connection.

The coloring of batteries (red and blue) uses the generally accepted coloring of water supply system pipelines.

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

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

You should also calculate the tank volume before purchasing.

How to choose a size?

It has been experimentally 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 can perform the calculation yourself and select a battery for a private home that suits your needs.

The key points will be the performance of the pumps and the volume of peak water withdrawal.

The volume of water in the tank should ensure that the pump pumps water no more than 30 times per minute.

The video below describes the structure of the hydraulic accumulator and why it is needed.

Tanks with a small volume are less effective at combating water hammer, however, too much water can lead to stagnation inside the tank.

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