Assembly of the hydroaccumulator and pressure relay. Installation of the hydroaccumulator for water supply systems with their own hands: Connecting to the submersible pump, the well scheme. Purpose of modern hydroaccumulator

Today it is unthinkable to imagine a house without water supply system. But sometimes there are cases that water can not always get to a particular water treatment point. Then the hydroaccumulator comes to the rescue, which regulates the pressure on the network. Then we are talking about which scheme for connecting the hydroaccumulator to the water supply system is effective.

Device hydroaccumulator

For normal operation of the water supply system in the house in some cases, a hydroaccumulator is installed on the network site, which is a container with a metal case. Inside the tank is a rubber "pear", which plays the role of the membrane. The hydroaccumulator, which is the link in the water supply system, accumulates a certain amount of water under pressure. When operating plumbing devices, dishwasher or washing machines, the hydroaccumulator supplies a network with water.

The rubber membrane is fixed to the container body with a flange, which includes an inlet pipe. Inside the hydroaccumulator is designed in such a way that there is air between the internal walls of the cylinder and rubber "pear", which is compressed after it is injected into the tank with a pump - cycling or automotive. When downloading to the water tank, the volume of which is limited to pear, the compressed air counteracts the further expansion of the elastic rubber, thereby protecting it from the rupture. At the same time, compressed air provides the necessary pressure on the network.

If you take into account the design of the sample development hydroaccumulator, then the following components can be distinguished:

• the housing, which is a hermetically made tank, which is designed for the working pressure in the range of 1.5-6 atmospheres. This value can be increased to 10 atmospheres, subject to a short-term load;
• "Pear", which is an elastic membrane. It is attached to the front of the tank and is located inside the cylinder. The flow of water takes through the flowing flange, which is equipped with the valve and is fixed to the neck of the hydroaccumulator tank.
• nipple, which is arranged on the other side of the case - the opposite arrangement of the flow flange. The nipple is designed to be downloaded through it through it into the battery space, which is formed between the outer surface of the "pear" and the walls of the housing from the inside.

In addition to the main elements, the legs located below the stability for stability, and the support bracket for installing the surface type pump unit, which is located in the upper part of the cylinder.

Depending on the site of use, hydroaccumulators are divided into:

• products for working in the cold water supply system;
• devices for functioning in a hot water supply network;
• expansion tanks for heating systems.

The hydroaccumulator for the supply of cold water is designed in such a way that it accumulates and supplies fluid, and also has the ability to avoid hydrowards on the network and protect the pump unit from unnecessary inclusions. Analogue, which supplies hot water consumers, has the same characteristics as the above-mentioned product. The difference lies only in the properties of the membrane, which can withstand high temperatures. The purpose of the expansion tank in heating systems is compensatory capabilities in cases of water expansion.

Principle of operation of the hydroaccumulator

Water supply system, in the circuit of which there is a hydroaccumulator, works according to a specific scheme.

• Stripping from the water intake, which can be a water supply, well, or well, water in the pipeline is fed to the battery, namely into the rubber "pear."
• In the rubber membrane, using an adjusting relay, which defines the lower and upper threshold of the required parameter, the pump is created by pressure, for example, 1-3 atmosphere.
• After reaching the specified value in the pressure instrument, the pump automatically turns off.
• After the consumer opens the crane on the sink or includes a dishwasher, the membrane begins to push water from the hydroaccumulator and serve it on the network to the water treatment point.
• When the pressure in the device drops to a critical low mark, the relay is triggered and the pump automatically starts its work. But first you need to connect the pump to the hydroaccumulator.

The number of pump inclusions per unit of time directly depends on the volume of the cylinder. The smaller the tank, the higher the pump will be turned on with a high frequency. With this version, the pump and the flange with the valve will end the work resources faster. Since the external loads do not affect the balloon, it is not necessary to fix it to the floor. To ensure the stability of the hydroaccumulator, there is enough its own legs.

Options with a selection of a hydroaccumulator

The hydroaccumulators are different designs and volumes - from compact devices by 24 liters to overall products for 1000 liters. When choosing a drive, you need to take into account the volume of water, which is used by consumers in the house. If no more than two people live in the house and the minimum of sanitary devices and household items are established, then it is enough to purchase a capacity of 24 liters. If, on the basis of different factors, the water consumption is large, then the hydroaccumulator must be installed larger and volume. It is necessary to calculate how much water separation points can work at the same time and, repulscing from the calculated flow, select the appropriate capacity. If the water supply system is already equipped, and the situation has changed in the house - the number of tenants has increased or added, for example, a washing machine, then you need to change the battery for more or deliver another tank.

Connection diagram with an embodiment with a surface pump

Before connecting the hydroaccumulator for water supply, it is necessary to check the air pressure check in the container. It should be less than the pump pressure when turning on, which is displayed on the relay, to the value of up to 1 bar. To connect the tank to the pump, you need to purchase a fitting with outputs in the amount of 5 pieces, the relay that adjusts the pressure, pressure gauge and sealant in the form of a pacle or a fuma ribbon.

• One of the important details when installing the hydroaccumulator is a fitting on 5 outputs. Through this item to the tank joins the pump, relay and pressure gauge. Another 1 fitting output is intended for connecting the water supply, which branches down to the water intake points. At the initial stage, the fitting is connected to the tank through the hard hose or directly through the bandwidth flange with the valve. Then the adjustable relay and pressure gauge is screwed to the separation part, as well as a pipe that traceses further from the pump.
• Special attention should be paid to the connection of the relay controlling the pressure. The tower machine has the top cover that you want to remove. Under it there will be 4 contacts with the inscriptions "Network" and "Pump". Thanks to their presence, confuse the wire connection is hard. According to the labels, the wires connected from the pump and the network running to the network are connected.

Not all manufacturers on the relay put inscriptions, counting on the awareness of the Monter. If a person engaged in connecting the relay does not know which contact to connect one or another wire, it is better to turn to the professional electrician.

All compounds on the thread need to be thoroughly seal. For this work, you are suitable palable or fuma ribbon. In conclusion, you need to include a pump unit, after which it is visually and to the touch it is necessary to check the place of installation for the leakage.

Connection diagram with submersible pump

Already by the title, it can be understood that the submersible pump is placed in an aquatic well or well, where water comes directly to the hydroaccumulator. The water supply system with such a pump must be equipped with a check valve. This item does not allow water after the membrane to return to an in-depth water intake. As a rule, the check valve is mounted immediately to the pump, while the other end is connected to the pressure pipeline. There are varieties of pumps in which the fitting on the lid has an internal thread. Then, when installing, you need to use the item on which 2-outer threads are sliced. Following the check valve there is a pipe that is paved to the hydroaccumulator.

When installing the pump, it is necessary to consider that the unit must not reach the bottom of the well or the well for approximately 30 cm.

Video

On the provided video, it shows how the pump is connected to the hydroaccumulator.

To organize the normal operation of water supply in a rustic house from a well or a similar source, it is necessary to establish a number of special equipment. The package includes a pump, automation, hydroaccumulator and other equipment. In this article we will tell you about how the process of connecting and installing the hydroaccumulator for water supply systems is your own hands. We will offer you some working connection schemes. But first find out what is the equipment.

Hydroaccumulator - why he

There are several basic goals that serves a hydroaccumulator in the water supply system. First of all, its installation allows you to create the necessary pressure on the network. Also in the hydroaccumulator is stored for a small stock of water. For example, if for some reason the pump can not swing water, then you can use it. The volume of water determines the internal volume of the hydroaccumulator. Well, the most important, its presence in the water supply system of a private house prevents the formation of hydrowards.

Under the hydroaccumulator is meant a special metal tank. So that stable pressure inside it is maintained, it is equipped with special equipment. The water supply circuit with a hydroaccumulator is relatively simple and if you follow all regulations in this article, the connection can be performed with your own hands.

In most cases, the water supply system uses the principle of operation of compressed air. It consists of partition, for example, it can be a rubber membrane or rubber pear. So, the essence of the entire water supply system with a hydroaccumulator comes down to the following. Pumping equipment pumps water into the tank. As the tank fills, the pressure is formed inside it, as water presses the pear. All this process is controlled by a pressure sensor. It is important that the pump can be turned off. As soon as the crane is opening with water, the water is pushed by the energy of the rubber pear or the membrane.

As soon as the pressure in the hydroaccumulator drops, the sensor is triggered, which gives a signal to the pump, and it turns on. Thus, the hydroaccumulator is filled with water. Podka is carried out until the signal trigs off.

As can be seen, in addition to connecting the hydroaccumulator, it is important to correctly calculate the pressure in the water supply hydroaccumulator. For this purpose, you can use the recommendations of the manufacturer, which are indicated in the passport.

Today two types of hydroaccumulator are distinguished:

1. Open type.
2. Closed type.

As for an open type, it is extremely rare. And it is not surprising, because it has a number of negative sides, including:

• High coefficient of water evaporation. As a result, it is necessary to constantly pump water.
• Moreover, the installation of the hydroaccumulator for water supply systems with their own open-type hands will cost much more costly. This is explained by the fact that it is necessary to take measures that will exclude the likelihood of water freezing. Moreover, it is necessary to establish additional automation that will eliminate the likelihood of water overflow.
• An important minus is reduced to the fact that when the water with oxygen is in contact, its aggressiveness increases with respect to metallic parts. As a result, this leads to the formation of corrosion on metal, and this significantly reduces the service life.

Among other things, models are distinguished that are placed in a vertical or horizontal position. If the area of \u200b\u200bthe caisson or another room, where the installation and connecting the hydroaccumulator to the water supply system is minimal, then the vertical direction is selected. For horizontal, a special platform is necessary. The tank itself has special fasteners for mounting.

Important! You can find a hydroaccumulator for the water supply system of blue and red. Blue color for cold water pipes. From the red, it is characterized by the fact that the tank itself is able to work in a much greater pressure. Plus, food rubber is used inside the design.

Method of accommodation

Before connecting, it is necessary to understand the installation method, and, rather, the location. The choice of place will depend on the power of the unit. To create the highest possible pressure, it is recommended to select the highest point in the house, for example, insulated attic.

The selected place should be dry and not have air humidity. Otherwise, condensate will appear on the surface of the hydroaccumulator for the water supply system, which can provoke corrosion formation. And although the tank is covered with paint and varnish material, sooner or later rust will take its own. Plus, the selected surface must be durable and smooth.

Connection schemes

We now read in detail in what scheme it is possible to install a hydroaccumulator for water supply systems with your own hands. Consider two schemes with a submersible and surface pump.

Connecting the hydroaccumulator with a surface pump

First of all, checking the level of pressure in the container. As a rule, it must be less than that of the pump, which is set on the relay to 1 bar. To connect, a special fitting is needed, in which 5 different outputs. Each output is intended for certain purposes. Plus, you should buy a pressure switch.

As for the special fitting for five outputs, the following elements are connected through it:

1. To connect the pump.
2. Pressure switch.
3. Manometer.
4. To connect the water supply.

To start, the connection can be performed through a hard hose. After that, the pressure and pressure gauge, indicating the pressure level, is screwed to the fittings. You should also connect the pipe that will be directed to the pump.

When the pressure relay is connected, the following points are extremely important. On the device itself there is a top cover. It should be accurately removed. Under it you will find four contacts. Each contact will have an inscription pump and network. This greatly simplifies when the device is connected to the wire network, which comes from the pump. Connection runs strictly by specified tags.

However, not all manufacturers on the relays put signatures of such a plan. This is done from that calculation that the installer is completely disassembled. If you are new to this case, then definitely consider this factor. For example, when buying, make sure the inscriptions are available. In this case, you will not need to call a specialist in this profile.

Important! Absolutely, each connection on the device should be performed using a sealant. It is necessary that each junction is sealed. Usually it is used for this purpose a fum-tape or package.

Upon completion of these manipulations, you remains to include a pump on the network and adjust the pressure level in the hydroaccumulator. Plus to all, you should make sure that there is no leak on all the joints.

Connecting the hydroaccumulator with the submersible pump

In this case, the pumping equipment falls into the water. All water coming from the well will be pushed out of the vertical pipeline with the pump. With this execution, the water supply scheme of the well with a hydroaccumulator should include the check valve. As a result, water will not leave the membrane to the pump. In most cases, the check valve is installed immediately after the pump. Next is the pressure pipe on the surface.

Some pumps may have a fitting with internal thread. In this case, it is necessary to purchase a special adapter on which there will be two external threads of the corresponding diameter. This is important, because on the reverse valve also inner thread. The rest of the connection is the same as in the previous case. A special adapter is used for five outputs.

Determine and exhibit pressure in the hydroaccumulator

Regardless of the method and variant of the installation scheme of the hydroaccumulator for the water supply system, the correct adjustment of the pressure in the entire system also plays an important role and in the tank itself. So, in one part there is a compressed air, in the second water. When buying, at the factory, the manufacturer in the air chamber is given a pressure of 1.5 atmospheres. It is important to notice that this is a base unit regardless of the type of model and the cost of the hydroaccumulator.

Check and pressure correction

So, immediately before connecting it is recommended to check the pressure level in the hydroaccumulator itself. Due to this information, you will manage to make the correct pressure relay setting. Moreover, the future control of the pressure level is also extremely important. For this purpose, a pressure gauge is intended. Some home masters temporarily use a car pressure gauge. Its error is minimal, so quite normal.

If necessary, the pressure level can be reduced or added. For this purpose, it has nipple on the top of the hydroaccumulator. A car or cycling pump is connected to it. Due to this, pressure rises. If the air pressure, on the contrary, must be reduced, then there is a special valve in the nippele. You should take a sharp and subtle object and click on it.

What pressure should be

So it is important to determine how the pressure should be in the hydroaccumulator. If there will be home appliances in a private house, the pressure range must be located around 1.4 to 2.8 atmospheres. To eliminate the likelihood of the membrane breakthrough, then the system should be a slightly higher pressure than in the tank itself, at least 0.1 atmospheres. That is, if in the hydroaccumulator for the water supply system installed 1.8 atmospheres, then the system should be about 1.9 atmospheres. To set this, a special device is used, known as a pressure relay.

When determining the level of pressure, it is important to take into account the floors of the building. If you have a one-storey house, then the pressure will be lower than if you had to lift the water to the second floor. Another fact is also taken into account how many points of the water intake is in the house, how many people live and what is the probability that several cranes will be opened at the same time.

If all these nuances do not take into account, then the next picture can occur. You take a shower, while someone decided to wash the dishes or uses water for other purposes. As a result, the level of pressure and pressure of the water in the crane will sharply decrease. Agree, not quite a pleasant situation. So that this does not happen, it is important to properly set pressure on the hydroaccumulator and other equipment. And this will be possible if you consider all the listed parts and not only.

Conclusion

So, here we also reviewed the features of the use of the hydroaccumulator in the water supply system. We also led you simple hydroaccumulator connection schemes. As can be seen, there is nothing complicated in this matter. The most important thing is to correctly calculate the level of pressure and pick up the tank itself for the needs of the house. We hope that this article will help you figure it out in this difficult business. We are confident that you can cope with this work yourself. To secure the entire theory, we offer you to watch prepared video. It will help you visually see everything, how is the process of connecting the hydroaccumulator to the water supply system. If you already have a personal experience in this matter, you must share them by leaving comments on this article.

The hydraulic battery is called an installation that is used to maintain pressure and create a water reserve for domestic purposes during the pump is disconnected. This device is represented as a water tank with a rubber elastic membrane located inside her. The membrane itself has a hermetic compound with a metal body of the tank, which is carried out using a flange. The space located between the metal case and the membrane is filled with compressed air.

Without the use of this unit, it is quite difficult to imagine the efficient functioning of the whole. Accordingly, the selection of this device is as acute as much as possible. Subject to the absence of certain knowledge in this area it is rather difficult to choose the most suitable device. In this context, it is advisable to make a decision on the involvement of a third-party specialist in order to obtain advisory instructions.

Principle of operation of the hydroaccumulator

The hydroaccumulator consists of a metal case and membrane. Also in the device there is a flange with a bandwidth and nipple, intended for water injection. The principle of functioning the device is quite simple.

At the initial stage, the pump begins to pump water, which subsequently enters the rubber membrane inside the hydraulic battery. Capacity is filled to the moment until the pressure becomes maximum. The level of this indicator can be pre-set on the relay regulator. Subject to the maximum pressure, the pump is turned off automatically. It should be noted that the frequency of the inclusion of and disconnecting the pump directly depends on the volume of the hydroaccumulator - than it will be more, the less this procedure will be carried out.

Thanks to the installed hydraulic battery, the pressure inside the water supply system is able to hold out another period of time. This will allow a little to support the efficiency of the entire system.

Types of hydroaccumulators

First of all, when choosing hydraulic batteries, you should pay attention to the volume of the device, which can vary from 24 to 1000 liters. To do this, it is necessary to previously analyze the amount of water that is regularly consumed for household purposes. If we talk about the minimum needs in the form of a toilet, a shower, a kitchen, watering the beds on the adjacent area, it is quite possible to do with a battery with a volume of 24 liters. If we are talking about more global purposes, then you should take advantage of a more significant device. In extreme cases, if necessary, in an increase in the volume of water consumed, you can additionally set the second hydraulic minimum battery.

Classification by installation method

Under this feature, hydraulic batteries can be horizontal or vertical. The differences of such devices lies not only in the method of placement, but also in different removal of excessive air.

• In hydroaccumulators vertical type The installation of fitting with a valve, through which the air is designed. In horizontal hydraulic batteries, it is necessary to use an additional section of the water supply system, which consists of their ball valve, plum and air outlet nipple. Here it should also be noted the fact of lack of valve in the horizontal hydroaccumulators of the minimum volume.
• Hydraulic batteries horizontal type Used for subsequent installation on them outdoor pumps. Vertical applied while working with submersible type pumps.

Classification by appointment

Here it should be noted that there are three types of hydraulic batteries. Each of them has its own design features and various operating conditions.

• The first of them are intended for cold water. They are used to feed and accumulate fluid. In addition, such devices are capable of performing a protective function, minimizing possible harm from mechanical exposure, resulting from hydrowards at jumps of pressure indicators.
• The second type of hydroaccumulators is used for hot water. The peculiarity of this instrument is that it is capable of functioning at the highest temperature indicators of the fluid.
• The third type of hydraulic batteries is applied for heating systems And it is its very important element. Such batteries have the type of expansion tanks.

Features of connecting to the surface pump

The hydraulic battery can be connected to a surface or submersible pump. Technology of work in different cases will be somewhat different. When connected to the surface pump, it is pre-given attention to the inspection of air pressure in the tank. To carry out the procedure, you may need a fitting with five outputs, pressure gauge, palable and sealant.

The sequence of action will look like this:

1. Pressure check in the tank.
2. Connecting the fitting to Baku.
3. Relay connection.
4. Connecting a pressure gauge.
5. Connecting a pipe leading to the pump.
6. Testing and starting the system.

The fitting here is necessary for high-quality compound of pump, hydroaccumulator, pressure gauge and relay. The fifth output may be needed to connect the plumbing pipe leading to the house.

At the initial stage, connect the fitting to the Baku by using a hard hose or flange. After that, a pressure gauge, a regulator and a pipe that comes from the pump is screwed to it.

Important! At the end of the work, it is necessary to take very high qualityly all threaded connections through the use of packle and special sealant. Run the pump is necessary only after a thorough study of all sections on the fact of the presence of leaks.

Features of connecting to the submersible pump

Submersible pump, unlike superficial, is located directly or well. From there, water goes straight into the hydraulic battery. When connecting the device in this case, it is very important to focus on the installation of the check valve, which is necessary to prevent the disassembling of water membrane.

The hydraulic battery in this case is installed on the pump before water supply. In some cases, a thread is cut on the cover of a water pumping device. This is necessary in order to facilitate the installation procedure.

It should be very careful to install the check valve. This solution will help prevent the water extrusion of the membrane back to the well. This directly affects the quality of functioning.

After the installation of the check valve was successfully carried out, it can be proceeded to resolve the next question, which consists in connecting the pipe for water supply. Pre-measure the length of the pipe. To do this, you can use a simple rope with a cargo at the end. Measure the data is necessary from the edge of the well to the pump. It is advisable to make it so that subsequently calculating the length of the pump was able to hang over the bottom surface of the well approximately at a height of 20 or 30 cm.

Hydroaccumulator - the device is extremely useful, both for the organization of autonomous water supply and to improve the characteristics of the system connected to the central water supply.

A master who has at least a minimal experience of plumbing work, without any problems install a hydroaccumulator with its own hands and connect it to the water supply system.

Agree, the key to successful work is an understanding of the device and the principle of functioning of equipment. We will help you to deal with these questions, as well as we describe and illustrate the step-by-step technology of the installation of the hydroaccumulator.

Information about connecting, configuring and conducting current repairs of the cumulative tank is useful in the process of its operation.

From this device for the day of the day, water fence and its swap is made. As a result, the unit is constantly under the influence of the workflow, during which it is noise and vibrates. This moment should be considered by choosing a place to install it.

Schematically connecting the pump station can be submitted in the form of the following steps:

1. Prepare a solid base in a suitable place.
2. Install a pumping station for the base.
3. Measure and adjust the air pressure in the empty hydroaccumulator.
4. Install on the outlet of the hydroaccumulator fitting with five outputs.
5. Connect to the outlet of the fitting the pipe of the surface pump.
6. To another output, connect the plumbing pipe.
7. Fill with water hydroaccumulator.
8. Check availability / lack of leaks in the places of threaded connections.
9. Configure pressure switch.

The surface pump is used in the system of autonomous water supply of the private house far from always. Deep Well Owners have to use special submersible pumps.

The process of connecting the hydroaccumulator to the water supply system C is performed according to the following scheme:

1. Lower the submersible pump prepared for the work in the water source (well, well, etc.)
2. Connect the pressure hose or the pumping pipe of the pump to five connectors.
3. Connect the hydroaccumulator pipe with one of the fittings.
4. Install a pressure gauge and pressure switch.
5. Connect the hydroaccumulator to the housewater system at home.

When connecting a hydraulic pump with a submersible pump, an installation should be provided, which will prevent the water outflow in the well when the pump is turned off.

Several important nuances

Special flexible adapters are used to connect the hydroaccumulator. This helps reduce the effect of vibrations on the water supply system.

It should be borne in mind that in this area, between the water supply line and the hydroaccumulator, it is unacceptable a decrease in the lumen of the connecting structures, since it will worsen the hydrotechnical characteristics of the system.

To reduce the influence of vibration, which occurs when the hydraulicock occurs, it is recommended to use special flexible coupling. Their dimensions should not be less than the output diameter to which connectivity

Primary filling of the tank with water must be performed very slowly. The fact is that with long-term storage, the rubber membrane, made in the form of a pear, could simply stick together.

A sharp stream of water can break the gasket, and with a weak pressure, it gently plays. Another really important point - before the water supply to the hydroaccumulator, you should completely remove the air from the part to which water will be injected.

Immediately after unpacking the purchased battery, and / or immediately before it is connected it is necessary to measure the pressure of the air, which is injected inside. This indicator should be 1.5 atm, which is so pumped by hydroaccumulators in the manufacture. However, during storage in a warehouse before selling a leakage of this air, the phenomenon is completely natural.

The most reliable option for such measurements is an ordinary car pressure gauge with a suitable gradation scale that allows you to measure with an accuracy of 0.1 atmosphere. As practice has shown, to use cheap Chinese models from plastic for these purposes should not be, their accuracy is very dubious.

Electronic models are sensitive to the state of the environment, and this is too expensive for a conventional hydroaccumulator.

What is obliged to be air pressure in water filled with water? It all depends on the situation.

The pressure of 1.5 atmospheres will provide quite a decent water pressure in the plumbing system. But it should be remembered that the higher the pressure, the less the volume of water stored in the tank. If a solid water supply is also needed, and a good pressure, it makes sense to look for a large volume tank.

To control the air pressure in the hydraulic tank, it is recommended to use a conventional car pressure gauge, which allows measurements with an accuracy of 0.1 atmosphere.

It is recommended that in the hydroaccumulator, the operating parameters of air pressure were less than the minimum pressure indicators that causes the inclusion of the pump, about 0.5-1.0 atmosphere. Sometimes come differently.

The air pressure in the hydroaccumulator is left at 1.5 atmospheres, as they are installed at the factory, and the value of the minimum pressure or pressure pressure is calculated as 2.0-2.5 atmosphere. Thus, the air pressure in the empty tank is 1.5 atmosphere - add this difference in 0.5-1.0 atmosphere.

Excessive pressure is not too well reflected on the integrity of the elements of the hydraulician, but also low air pressure in it is not useful. If this indicator is reduced to a level of less than one atmosphere, the membrane will touch the walls of the tank. This will lead to its deformation and quick breakage.

Two springs are designed to regulate the pressure relay. Using the first exhibit the pressure of the pump, and with the help of the second - the difference between the maximum and minimum pressure

After the system is installed and connected, you must configure the pressure relay. To do this, under the case there are two adjusting nuts with springs. The procedure for adjusting the pressure relay is usually described in detail in the instructions that are attached to the device.

Rules of operation and repair

Connect and configure the hydroaccumulator correctly - this is only half of the case. In order for the device to work for a long time, it is necessary to competently operate, periodically perform a prophylactic inspection and maintenance.

Instructions are prescribed to carry out the professional expectation twice a year, but practice shows that this is not enough. Check the condition of the hydroaccumulator follows every three months. With the same periodicity, it is desirable to observe the settings for the pressure relay to correct them if necessary.

Incorrect operation of the relay creates additional loads on the entire system, which can also affect the state of the hydroaccumulator.

If during the inspection on the case of the device detected dents or traces of corrosion, these damage must be eliminated. It is best to do this as early as possible, otherwise the corrosion processes will develop, which can lead to a violation of the integrity of the body of the hydroaccumulator.

An important prevention measure is to test the pressure in the hydrobian itself using a pressure gauge. If necessary, the device should be screwed up the desired amount of air or to express its excess.

If this does not help and new testimony of the pressure gauge does not correspond to the expected, it means that the integrity of the hydroaccumulator body is impaired, or its membrane is damaged.

If the membrane installed in the hydroaccumulator was worn out, you can try to replace it with a new one. For this, the device will have to dismantle and disassemble

Some craftsmen can detect and close the places of damage to the housing, but not always such a repair is durable and reliable. Rubber liner or membrane is a weak place of the hydroaccumulator. Over time, she wear out.

It is possible to replace the membrane with a new element at home, but for this you will have to completely disassemble and re-assemble the hydroaccumulator.

Choosing a suitable place to install a hydroaccumulator, it should be remembered that it should be spacious enough to carry out maintenance of the device

If the homemade sample doubts his abilities in this area or does not have sufficient experience, it can apply even more harm to the device than the former breakdown. In such a situation, it is better to contact the service center.

Conclusions and useful video on the topic

Overview of the operation of the hydroaccumulator by 50 liters is presented in the following video:

This video material clearly demonstrated the procedure for adjusting the pressure in the hydraulic and pressure relay settings:

The advantages of using the hydroaccumulator are obvious, therefore, this device is increasingly used in private homes outside the city, and in the apartments of the metropolis. If the unit is installed and connected correctly, it will work for many years without breakdowns and interruptions, providing a seven quality water supply.

Do you have experience in self-installing and connecting the hydroaccumulator? Please share information with our readers, tell us about the features of the configuration and operation of the hydraulician. You can leave comments in the form below.

The most important element of the pumping station is a hydroaccumulator.

The circuit of connecting it to the well depends on the degree of autonomy of water supply and the absence or presence of a water heater in the plumbing network.

Consider possible installation options, as well as the device and types of hydroaccumulators.

In the simplest performance, the hydroaccumulator (GA) is a container installed at a certain height (above any of the consumers) and equipped with level sensors.

An example of such a device is the water tower that feeds the water supply network in some rural settlement.

In autonomous water supply systems of private houses, such a hectare is usually installed in the attic.

The pressure in the cranes is ensured by the weight of the fluid column, the level sensors or the float switch control the operation of the pump.

In modern pumping stations, more advanced has, which can be installed at any level - even below the water displacement points. The volume of such a device is divided into two parts: water from the water supply pipe is poured into one, the air contains air with some excess pressure (pumped through the pump through a conventional spool).

Both parts are separated by an elastic element, so when filling in one of them, the volume of the second decreases, respectively, the pressure of the air in it increases. It is the pressure of the air that performs the same function in such a war as gravity in the water tower, - provides pressure in the system.

Constructively ha are divided into two varieties:

1. Membrane: Volumes for water and air in such tanks are separated by a rubber membrane. There are membrane tanks intended for use in closed heating systems. They are designed for less pressure than ha for water supply, moreover, they use technical, rather than food rubber. To avoid confusion, heating is taken to be painted in red, and for water supply - in blue.
2. Balloon: The rubber bag with a flange is inserted into the inside of such a drive, which is connected to the water supply. Thus, in balloon hectares, water with metal walls of the case does not inactit. In addition, the replacement of the cylinder does not represent any difficulty and can easily be implemented by the user, while to replace the membrane in some models you have to contact the service center.

Water in the balloon hectares when you first start, it should be served very carefully. The walls of the rubber bag may slide a little, then the strong head will break it.

By volume hectares can be very different - from 24 to 1000 liters and more. It should be borne in mind that the passport provides a total volume of the tank including the air chamber.

As for the volume of water, which can accommodate the tank, it will depend on the settings for the pressure of the amount of injected air.

So, when settings for a relay 1 atm / 2 atm (pressure / off pressure) and air pressure of 0.8 atm (checked with an empty cylinder) 30 liters of water will fit 100 liters.

If the disconnection pressure lift up to 2.5 atm, the capacity of the drive will increase to 38.5 liters.

In the gene volume of over 100 liters in the upper part of the water chamber, an air reset valve is established, which is released from the liquid during operation and gradually accumulates. Tanks with a smaller volume of such valve do not have and to get rid of the accumulated air, they are periodically emptied.

Ha may have a horizontal and vertical execution. The device and principle of operation in both varieties is completely identical, the choice of a particular model depends solely on the convenience of installation.

The hydroaccumulator has an extremely simple device, the connection can also be connected independently. - Recommendations for choosing and installing, read carefully.

Place in the water supply system

If the work of household water supply was provided by the pump alone, it would have to turn on each time, as soon as any of the users opened a crane.

Such a mode would lead to the emergency development of the electric motor resource, since the start of the start is the hardest for it.

In the passport of the pump, it even indicates such a parameter as the maximum permissible inclusion frequency.

Even for the most endless electric motors, it is no more than 15 launches for an hour, for all other - 10 or less.

This is what the use of hectares is due. It accumulates not only water, but also the pressure necessary for a comfortable use of the water supply. At the same time, the pump operation mode looks completely different: it works longer, but is the most important thing - less often turns on.

Along the way, the membrane or balloon drive performs another important function: it acts as a damper smoothing the hydrowarders.

However, in the water supply systems, he is not always needed. So in what cases without it you can do:

1. If the water is spent by durable cycles: a typical example - watering the garden. Here he is not just not needed - he is contraindicated. The water supply in it will be spent very quickly and the pump will have to be frequently turned on to replenish it. In the absence of hea, the unit will safely work in stable mode.
2. If the pump is equipped with the latest automation, in which the function of the smooth start of the engine and the adjustment of its power depending on the pressure in the system.

For the service life of such a pump, the inclusion frequency does not have any influence. It is believed that the station on the basis of such an aggregate of hectares can not be equipped.

Connection Scheme Hydroaccumulator for Water Supply Systems

The method of connecting the hectare will depend on the features and purpose of the pumping station. Consider three options.

Option 1

The pump serves water from the well, well or storage tank, while only cold water supply is organized.

In this case, the ha is installed inside the house at any convenient location.

Usually it, the pressure relay and pressure gauge are connected using a posterior fitting - cut pipe with three taps, which is crashed into a plumbing.

To secure hectares of vibrations, it is attached to the stacker with a flexible adapter. To check the pressure in the air chamber, as well as to remove air, accumulated in the water chamber, the hectare must be emptied periodically. Water can be drained through any water tap, but for the convenience of the drain valve, it is possible to cut into the supply pipe somewhere near the reservoir somewhere.

Option 2.

The house is connected to the centralized water supply, and the pumping station is used to increase pressure. With this method, the use of the hectation station is connected before the pump.

In this case, it is designed to compensate for the pressure reduction in the external highway at the time of running the electric motor. With this connection scheme, the amount of hectares is determined by the power of the pump and the magnitude of the pressure jumps in the external network.

Installation of the hydroaccumulator - scheme

Option 3.

A storage water heater is connected to the water supply. Ha should be connected to a boiler. In this embodiment, it can be used to compensate for an increase in water volume in the heater due to temperature expansion.

Connection diagram of the hydroaccumulator to the submersible pump

In the event that the pressure characteristic of the submersible pump allows you to maintain an acceptable pressure on watershed points in combination with sufficient performance, ha connects along a conventional scheme using a five-water or three-water fitting.

However, wells are very deep, while their dimensions often do not allow to establish a pump of sufficient power (for example, 3-inch wells).

Connecting the hydroaccumulator with your own hands

In such cases, apply the following scheme:

1. The submersible unit is installed in the well, the power of which is enough for the rise of water to the surface.
2. Next to the well on the surface or in the ground is installed in the form of a simple container equipped with level sensors. These sensors control the operation of the submersible pump.
3. Self-priming type pump is installed near the cumulative capacity (if it is burned in the soil) or normal suction (if ha was installed on the surface), which gives water directly into the home water supply. At the same time, the house establishes a membrane or balloon hectare, and the pump control is carried out by means of pressure switch.

The volume of ha, installed immediately after the submersible pump, should not be done too large, otherwise the water in it will be stamped.

Electrical Pressure Relay Connection Scheme for Hydroaccumulator

Usually, there are two groups of contacts in the pressure relay of household pumping stations, but sometimes there are models with one.

Each group consists of two pairs, and both pairs are closed or opened at the same time. Contacts in each pair have designations, such as "Line / Load" or "Line / Motor".

In principle, not necessarily follow these designations. You can even, for example, the wires of the wires from the network to join the "line" contact of one pair and the "Load" contact.

The main thing is that both veins are not connected to the contacts of one pair - this will lead to a short circuit. For the remaining two contacts, connect the veins of the wire leading to the pump motor. It is desirable that the colors of braids lived, connected to one pair, coincided. Before connecting the network wire, make sure that it is not enabled in the outlet.

To connect grounding core (usually it has a yellow-green braid) on the relay housing there is a screw marked with the corresponding sign.

When connecting the wire from the relay to the pump electric motor, the living in the blue braid should be connected to the "zero" contact, and in red or black - to the "phase" contact.

Often, for reliable, the contacts of grounding pump and relays are connected to each other, but it is not necessary to do this.

Pressure switch in the water supply system with the deep pump

The cross-sectional area of \u200b\u200bthe wire wire must correspond to the power of the electric motor. For a copper wire, the cross section is selected at the rate of 1 square. Mm for every 8 A current. To determine the strength of the current in a single-phase network, the power of the electric motor is divided into 220. So, for example, in the circuit of an electric motor with a capacity of 1.5 kW will leak current by force 1500/220 \u003d 6.8 A.

It is important not to confuse the values \u200b\u200bof the diameter of the wires of the wire and the area of \u200b\u200bits cross section, since these values \u200b\u200bcan be commensurate. So, for example, the cross-sectional area of \u200b\u200bthe vein with a diameter of 1.5 mm is 1.76 square meters. mm.

It should be noted that the connection of the electrical part only needs to be performed only after the pressure relay is attached to the water supply.

Nowadays, the lack of centralized water supply is no longer such a big problem. A wide variety of pumping equipment allows you to arrange an autonomous water supply system without much difficulty. , Installation and repair, read further.
