Automation unit dzhileks pressure adjustment instruction. Dzhileks the block of automatic equipment does not include the pump. Dzhileks automation unit pressure adjustment setting. Possible causes of failure

Automation mechanisms for the pump are used to ensure battery life devices with the appropriate mode setting. In addition, high-quality automation protects the pumps from dry running and saves energy consumption. This approach allows you to extend the life of an 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.

1 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 for the operation of the device in side surface block has a built-in pressure gauge.

The device is designed to operate on the basis of 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.

1.1 How the instrument works

Gileks automation operates independently from the usual 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.

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.

2 Correct installation of the device

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

1. 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.
2. 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.
3. 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.
4. 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 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:

1. In the first case, water will flow from the tap in a continuous, uninterrupted flow. The block turns on and pumping device works throughout the entire period of use of the crane. In this case, the installation of the device is correct.
2. 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

Automation from Gileks 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 pressure equalization mechanism is installed on a vibration, centrifugal, vortex, screw pump.

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

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:

• 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 operates on the basis of a standard 220 V electrical network. Suitable for connecting 2-3 water intake points at the same time. The adjustable relay allows you to set the pressure level that the device will maintain before starting work. Like the previous type of devices, Crab 50 is a universal device and is suitable for connection to borehole pumps any manufacturer.

4.1 Pressure switch RDM-5

More simple option automation of a pumping station is the installation of a special relay RDM-5 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, the 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.

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 the pipeline with a section of ¼ inch. A prerequisite when using RDM-5 is a high-quality grounding.

4.2 Float switch Gileks

For drainage, fecal and surface pumps for water, 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.

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.

The device and principle of operation of the water pressure switch

Structurally, the relay is made in the form of a compact block with springs for maximum and minimum pressure, 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 own version mode of operation 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 pressure is set to turn on, the tank is filled large quantity water, and there is no need to frequently turn on the pump. 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. 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.

The accumulator and pressure switch form reliable system to ensure water supply of any premises, outbuildings, fields and others. 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.

You can always connect an additional accumulator, as well as relays, automation, sensors and pumps.

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.

1. 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.
2. 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.
3. 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.
4. 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.
5. 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 competent connection hydraulic 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 against outside containers. 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:

1. The accumulator tank threads need to be sealed with tape to avoid water leaks, air intrusion into the system, facilitate maintenance, and also for easier subsequent repair and replacement of pipes.
2. 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.
3. 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 they put all the automation in hard-to-reach places- in narrow back streets, 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.
4. Just in case, the pressure gauge can also be glued with sealed tape, although a gasket is used there.
5. From plastic pipes and fittings, it is required to solder an elbow for the consumer line.
6. The regulator is connected to the knee thanks to the MPH coupling soldered to the pipe and using a brass adapter.
7. For deep, submersible pumps, polyethylene pipes are more often used. To hermetically connect them to the relay, a collet coupling is required.
8. The preparatory part is completed and then it is required to connect the accumulator and pressure switch to the rest of the pumping station.
9. After connecting to the pipeline, it is necessary to connect the electricity.
10. 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:
Let's say the pumping station is connected (more on this in the article "Preparing the pumping station DAB stations to work"), 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 exactly 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 need to regularly monitor the air pressure, or at least control it once a year at the beginning holiday 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 point of view 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. AT membrane tank water enters until it is completely filled, which leads to an increase in pressure. With the achievement of the maximum acceptable level the pump stops pumping fluid.

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.

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! Electric installation 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 is adjusted, which has big sizes. 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 more high price, as they allow to produce more fine 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 automatic device We invite you to 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 stop condition of 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. Choosing a convenient location for the pressure gauge, with opposite side plug the hole 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 draw-off point (faucet) so that the inlet ( external thread 1″) was 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. You must use an electrical cable with thermal resistance not lower than 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

Exist different means automation for pumps, among which 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. Newest 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 supply to the house is carried out using a pump 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 container with a membrane is installed in the house - a hydraulic accumulator, and required pressure the network supports 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 connection to water supply network, spring valves and electrical relay. Outside, the elements are covered with a plastic cover. The scheme of operation of the pressure switch RDM 5 is as follows:

1. 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.
2. When the pressure has risen to the upper limit (2.8 bar), the spring valve and opens the relay contacts. The water supply is stopped.
3. 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 regular pump is small to ensure the supply of water to 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 individual elements, and set the pressure switch 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 any of specifications relay RDM 5 does not suit you, 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 for outdoor and internal pipelines must be checked by tests so that subsequent leakage does 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 resistance. 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.

1. 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.
2. Remove the plastic relay cover covering the adjusting screws.
3. 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.
4. 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 limit 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:

Scheme of connecting the relay to the expansion tank

• 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.

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 large nut to turn off the pump, best option- 2.5–3 atmospheres, let's 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 with a bicycle pump to expansion tank to the required 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 determines 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. Correctly installed relays pressure RDM 5 "Dzhileks" will make the pump mode more economical, reduce power consumption and last a long time.

It is not always possible to repair the Gilex pump on your own, but there are a number of minor malfunctions, for the elimination of which it is not necessary to contact a service center. Homeowners who operate pumping units of this brand at home will not hurt to know how to proceed in the event of a particular breakdown. After all, it is extremely uncomfortable to do without water supply for a long time, it is better to try to disassemble and repair the Gileks device with your own hands. If that fails, you can always take it to the experts.

Possible causes of failure

The main thing is not to cause even more damage to the unit when trying to repair, so you need to act carefully and start by finding out the causes of the malfunction. To provide water supply to private households, 2 types of pumping devices are used:

• submersible pumps Dzhileks of the Vodomet series;
• surface pumping stations Dzhileks Jumbo.

The former are used to raise water from deep wells or wells with a depth of 20 m and supply water inside the dwelling. They are constantly under water, being submerged to the bottom of the well. Surface stations are located outside, in a technical room or a caisson, and are set to pump water from wells or tanks, the depth of which does not exceed 20 m.

Before thinking that the Gilex submersible pump itself is faulty, it is advisable to make sure that the well supplies enough water. If its performance has decreased due to different reasons(for example, silting), then when the level drops, the automation of the unit will not allow it to turn on “dry”. Therefore, periodic failures household appliance most likely, they speak of a lack of water resources.

The second point: it is impossible to determine the breakdown and its cause when the unit is immersed in the well, in any case it will have to be raised to the surface. Exception - failure circuit breaker, through which electricity is supplied to power the Water Jet pump. In this situation, it will not be necessary to extract it.

Possible reasons downhole unit failures look like this:

• insulation failure or mechanical damage power cable;
• break in the electrical circuit inside the pump;
• wear of impeller parts;
• engine bearing wear;
• abrasion of contact brushes;
• short circuit in the winding and, as a result, its burnout.

The first 3 causes can be detected and eliminated on your own. If the unit emits a hum when turned on, but does not pump, and when touched, an electric shock follows, then the capacitor has burned out or dried up. As for replacing bearings, brushes or rewinding the motor, you will have to contact a service center for this.

Malfunctions of pumping stations

These complex devices are quite reliable in operation. The first problems may arise 4-5 years after the start of work, provided that there were no emergency situations in which the pump had to rotate the impeller without water. And then these malfunctions rarely occur in the engine of the unit, but appear in other elements of the station:

• membrane hydraulic accumulator;
• pressure switch;
• check valve.

The most common problem leading to the complete failure of the pump motor is a malfunction check valve. It begins to let water through due to wear or clogging, the supply pipe is emptied, and the impeller rotates “dry”. Also, the rubber "pear" (membrane) installed in the reservoir of the accumulator may lose its tightness. There are also problems with the pressure switch, then the unit does not turn on when there is a drawdown in the house.

Troubleshooting

Malfunctions associated with the interruption of the supply of electricity to the pump are characterized by the absence of signs of "life" when the power is turned on.

To check the integrity of the electrical circuit, you must use a continuity tester or a multimeter included in the resistance measurement mode. If the power cable is intact, then you need to go to the inside of the unit, for which it will have to be disassembled.

For disassembly, you will need a standard set of locksmith tools that is available in every home and includes:

• screwdrivers;
• pliers;
• keys of different sizes;
• wire cutters.

As an example, consider the process of disassembling a borehole pump Gileks model Vodomet 60/52. The sequence of work is as follows:

1. Disconnect the unit from the mains and disconnect the suspension device.
2. Place the household appliance in a vise, laying thick rubber gaskets between the jaws and the body. Unscrew the screws of the cover, in which the holes for the water intake are made, and remove it.
3. Access to the shaft with impellers mounted on it, intermediate washers and glasses will open. They must be unscrewed and removed, laid out in the prepared place in order of priority, so as not to be confused during assembly.
4. Place the housing in a vertical position with the shaft pointing downwards. To do this, you need a surface with a hole or a suitable stand.
5. With a light blow of a hammer on the top cover through a wooden adapter, move the plastic retaining ring a few turns of thread. Then pry it off with a screwdriver, turn it 90° and pull it out with pliers. If necessary, a screwdriver can be used as a guide to hit to turn the ring.
6. Following the plastic locking ring, pull out the engine of the unit. Handle it with care as the engine is filled with oil. It can be drained if necessary.
7. Remove the cover of the compartment where the wires are connected. It is mounted on rubber seals and is knocked out with a flat screwdriver.

Now that the pump has been disassembled, it is possible to check all electrical circuits, up to the motor windings. In a situation where the case of a household appliance is energized, it is necessary to replace the capacitor. Carefully examine the condition of the plastic impellers, cups and intermediate washers. When worn, they must be replaced, for which you will have to buy or order the appropriate repair kit. It is pointless to put worn parts back, because when the shaft rotates, they still cannot create the necessary pressure in the water supply network.

Unlike submersible pumping devices, in the Gileks Jumbo pumping station, the accumulator and pressure switch most often fail. Motor brushes may also wear out, but it is better to contact specialists to replace them. service department. The smell of melted insulation and plastic indicates the burnout of the windings; the problem is most likely solved only by replacing the motor.

The rubber bulb in the reservoir of the hydraulic accumulator cannot be replaced, and in case of loss of tightness, it is necessary to change the entire reservoir. To check, it is enough to remove the accumulator by disconnecting it from the station, unscrew the side plug and spool, and then fill it with water from the injection side. If water runs through the spool, the battery should be replaced. They do the same with a pressure switch that cannot be adjusted - they change the entire element.

• extend the life of the pump;

General working principle:

When choosing automation for a pump, consider the following specifications:

• connecting dimensions in inches;
• power consumption;
• network voltage;
• degree of protection;
• the highest water flow rate (liters per minute);
• maximum withstand pressure;
• temperature range of the working environment.

Specifications Description

Without pumping units not a single network of autonomous water supply is bypassed. They create the required pressure, providing fluid supply to the points of water intake. However, the use of water will become really convenient only if there is automation for the pump. This function block will output the water management quality to new level. As a result, the operation of the equipment will be optimized.

High-tech and functional automation:

• extend the life of the pump;
• will start and turn it off depending on the pressure of the liquid in the pipeline;
• protect the pumping group from "dry running";
• minimize the number of emergencies;
• provide automatic maintenance required technological parameters;
• will increase the comfort of system management (the user will no longer have to constantly monitor the operation of the equipment).

The device and principle of operation of automation for the pump

There are various means of automation for pumps, among which 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").

The specifics of the choice and installation of automation for the pump

Installation of the automation unit is carried out in a vertical position in any place located between the pump and the first water distribution point (faucet). In this case, the outlet pipe is connected to the pipeline, and the inlet pipe is connected to the outlet fitting of the electric pump.

• all hydraulic connections must be tight, the pressure gauge is fastened through the sealing ring;
• if a pump with a working pressure exceeding the maximum allowable values ​​is used, a pressure reducer is installed at the inlet to the unit;
• with a high current strength, a magnetic starter is additionally mounted;
• for electrical connection, the circuit shown on the casing of the circuit board is activated;
• before the first start, the suction pipe and the electric pump are filled with water, and only then is it connected to the network;
• strictly follow the safety requirements provided by the manufacturer - this will ensure stable operation of the system, protect against injuries and emergencies, and retain the right to warranty service.

When choosing automation for a pump, consider the following specifications.

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.

1 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.

The device is designed to work on the basis of a pumping station or other surface pump that pumps 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.

1.1 How the instrument works

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.

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.

2 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:

1. 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.
2. 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.
3. 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.
4. 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 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:

1. 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.
2. 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

Automation from Gileks is a universal device. With it, the operation of pumping devices from various manufacturers can be regulated. Regarding the principle of operation, such a pressure equalization mechanism is installed on a vibration, centrifugal, vortex, screw pump.

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

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:

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

4.1 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, the 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.

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 the pipeline with a section of ¼ inch. A prerequisite for using RDM-5 is high-quality grounding.

4.2 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.

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.

One of the solutions for managing autonomous water supply is to connect an RDM 5 pressure switch to the pump, an adjustment whose instructions are not always clear to the user. At the same time, this type of device from the Gileks brand is considered to be quite reliable and affordable. The problem of setting, if desired, can be solved if you spend a little time studying the operation of the device.

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 necessary 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:

1. 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.
2. 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.
3. 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:

• control range for pressure 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.

1. 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.
2. Remove the plastic relay cover covering the adjusting screws.
3. A large screw regulates the upper limit (pump shutdown), a 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.
4. 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.

And the installation is 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 automation for the pump, having a long service life and good performance. Let's take a closer look.

1 Total pump automation

1.1 How does it work?

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 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 allows you to extend the life of the system.

1.3 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:

1. 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.
2. 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.
3. 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.
4. If a 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.
5. 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, it 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.
6. 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. automatic system, and has plus and minus markers.

1.4 Starting the automatic system

Important! When the incoming water level is below the level at which the pumping system, must be mounted on the inlet pipe.

We start the automation as follows:

1. 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.
2. 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.

1.5 No-load protection

When the “Protection” LED lights up on the automation unit, and the pump itself is turned off, this may indicate a danger idle work systems. 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 click the "Reboot" button.

2 Optimum 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 operating pressure= 1-4 atm.;
• Load current = 6-10 A;
• Water flow rate = 70-100 l/min;
• Upper pressure threshold = 15 atm.;

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.
