Hydroaccumulator for water supply systems: hydraulic tanks and a device for cold, pressure 100 liters

storage for water supply systems is considered a very important acquisition Often it is necessary to deal with the frequent turning on and off the water supply pump at a makeshift water supply, as well as require an additional stabilizer, avoiding problems with hammer and power outages. It is the accumulator accumulator that avoids all of the above.

What is the hydraulic reservoir towater supply systems

It is arranged the hydraulic storage tank is easy enough. Outside, it resembles the most common tank, in which there is a horizontal or vertical variation of the layout, installed in a specially designated place. This capacity is connected to a water pump, as well as a relay that regulates the pressure inside the pipeline.

Options:

1. Work tank with a specific volume.
2. Elastic internal container for the production of which high-strength butyl rubber is used. It is located inside the tank and must be securely sealed. On
3. elastic container mounted pneumatic valve, due to which the control for changing the pressure of water that is pumped inside.
4. It is mandatory to have a safety valve that controls the level of the air pressure limit value.
5. The threaded connection pipe is responsible for the flow of water into the accumulator tank.
6. No less important is the presence of a mounting bracket, through which the product is mounted.

Hydraulic storage tank is installed in a dedicated location

A typical battery is installed in a private house, which is ideal for functioning in a drinking supply network, in which a number of specific elements are present. The hydraulic accumulator tank can be additionally equipped with a pressure gauge, connecting pipes and a valve to carry out manual pressure relief.

Important!It is strictly forbidden to use the same water tank for pressure regulation in cold and hot water supply pipes.

Including it has a significant difference from the expansion tank. The level of pressure and temperature is completely different, which can affect such operational characteristics as service life, reliability, serviceability, product integrity, as in some cases the tank is simply torn. To be more precise, it is possible to damage the elastic membrane.

Accumulator unit and its components

To start the device, it is required to immerse the pump( it can be submersible or surface type) into water, while maintaining a specific level of pressure supplied to the elastic membrane tank.

hydraulic tanks have a certain principle of operation, but the design will function properly in the event that:

• installed using an instruction;
• Everything is carefully sealed;
• The product fully complies with GOST standard in its quality.

Accumulator unit

Capacity expansion and air pressure increase located in the space between the membrane cavity and the inside of the tank housing. Increasing the pressure helps to disable the relay, through which the pump operates, and at this time, water enters the distribution points installed in the house.

By how quickly the flow of liquid will be carried out, it decreases in the cavity of the membrane.

This means that the air pressure decreases, and the relay is switched on again for dialing, but this occurs at a certain level set by the manufacturer. After switching on, the cycle is repeated a second time until the next blocking of the pump.

Hydraulic storage tank for cold water supply: classification

The cold water supply control unit, the operation of which is considered quite simple, can differ by some criteria, so when buying, you need to pay attention to a number of features.

The capacity of the container can be( l):

• 40;
• 50;
• 100;
• 120;
• 150;
• even at 400.

Large-sized tank is needed exclusively for the industry, and it is quite rare to meet it in domestic conditions. The complete set of the pump station can be different, depending on what type of installation will be, in particular, horizontal or installed vertically. There are no special differences and advantages between them, since both versions are compact in size, but there is a difference in the laboriousness of the installation process and no more.

Hydraulic accumulator tank for cold water supply can be of different volumes

The housing material may differ, as there are stainless steel tanks, but the cost is much higher than the cheaper models made from the most common steel sheet and coatedEnamel.

The tanks differ in the manner in which air is vented with periodic monitoring of the pressure in the cavity of the body of the device. For this, a conventional valve or a common valve may be installed. The latter option is most often installed in a hydroaccumulator designed for a large amount of water. If you want to install a pressure pump, you need to be as precise as possible to the process of selecting it, since the device must be certified and have the necessary documentation to comply with GOST standard.

Optimum pressure in the accumulator for 100 and 200 liters

It is worth noting that the air pressure in the accumulator will affect how it works qualitatively, however, before installing the hydropneumatic tank for the water pipe, it is desirable to choose a device according to the size and other nuances.

When selecting, it is necessary to take into account again a number of features:

1. How much water is consumed per day, as this will affect the capabilities of the pump for water supply, and the selection of each part must be carried out at the same time, eliminating the discrepancies in the connectors.
2. What pressure will the energy storage in the water supply network support?This will be affected by the power of the equipment, as well as the strength of the enclosure. For example, cheap pressure stations do not exceed the pressure of 2 atm, which in some moments may lead to a malfunction.
3. Whether the pump is submersible or surface is also dependent on the size. For example, with a submersible version, the location of the hydraulic pump at the outlet is necessary, which will prevent additional and unauthorized switching on and off. If the pump is of surface type, then the installation of the accumulator must be carried out in close proximity to it. The higher it is located, the smaller one can choose the design by volume. The surface pump is installed on a tank much smaller than that for a submersible pump.

When choosing a hydraulic accumulator, pay attention to its technical features.

Whether or not there is a check valve in the interior of the house is dependent on pressure. For example, in the absence of such a valve, the tank is installed in front of the place where the tee is installed in the water supply circuit, and a manometer is required. For technical safety it is permissible to switch the pump on and off at an hour not more than 25 times, which will prevent the occurrence of breakage and repairs.

Principle of operation of the accumulator in the water supply system and its capacity

When supplying the water supply system with automation, it is necessary to check it for leaks and malfunctions, and if so, establish the causes of their occurrence, which will allow for more competent service. It is worth noting that some prefer to install a self-made hydro-pneumatic receiver.

However, assembling it with your own hands requires:

• Strict compliance with the technology;
• Compliance with recommendations from specialists;
• Use only high-quality materials.

In this case, do not pay attention to such moments as, for example, what color the tank, blue or red. After the collection, you need to conduct a complete overview of the structure for troubleshooting, which directly affects its validity. As for the capacity of the tank in the hydroaccumulator, it directly depends on how many points water enters the house.

How the hydraulic accumulator works

For example, for a family of 2 people, 50 liters is enough, but for 3 or more - 150 or 200 liters.

Choosing the types of tank capacity, you must immediately determine the location. When mounting a vertical view, it is necessary to add a third of the volume to the design pressure value, which will make the pump run much less frequently. However, it should be taken into account that the room where the equipment will be installed should be warm and without sudden changes in temperature, which can lead to a breakdown of the device.

Water accumulator for water: installation

As already mentioned, for the heating and hot water supply, the accumulators are not considered particularly suitable. In addition, it should be taken into account that with improper installation of even the highest quality equipment, problems can arise.

Why and which tank has problems:

• It is impossible to drain the water, since the sink is airborne;
• After stopping the pump, the water flows back to the source;
• The tank fills a little;
• The nipple begins to leak;
• The pump does not hold the pressure, and it sharply, rather than gradually falls;
• Download is very slow and so on.

The hydraulic accumulator for water must be properly assembled.

All these faults are associated with an illiterate installation. In order to be sure after the assembly or purchase and subsequent installation that the entire system is working properly, it is worthwhile to test. It is necessary to check the integrity of the structure and connections. The pressure inside the tank is measured with the aid of an automobile pressure gauge. A connection is made to the outlet in the pump and a hole in the water supply system, with the additional installation of a safety valve.

Required to be pumped into the hydro-accumulator water, and then the relay must be set up.

The capacity of the accumulator is filled with water, and gradually, so that there is no rupture of the membrane. At this point, you need to carefully monitor the data on the manometer and monitor the correct installation and operation of the relay. The pump turns on and the pressure is monitored, which should decrease by no more than 10% at start-up. It is advisable, with the purpose of prevention, to check the general condition of the device once a month, which will help to find problem areas in the equipment as soon as possible and eliminate them at the initial stage of failure.
