Membrane tanks for water supply as important elements of closed systems

An important element of the water supply system ishydroaccumulators or, in other words, membrane tanks. For water supply, they are of great importance. First, they act as water storage tanks and serve to maintain the necessary pressure and optimal functioning of the system. Secondly, the membrane expansion tank for water supply serves as a damper for hydraulic shocks, which often appear when the pump is turned on or when the cranes are opened. In addition, it is this equipment that creates the necessary pressure for the proper operation of the entire water supply system.

The principle of operation of such an installation is quite simple. The hydraulic accumulator is a container made of steel, inside of it there is a rubber membrane, where water enters. There is air between the tank wall and the rubber bulb. When the consumer opens the tap, water will begin to flow under the initially set pressure. When the tank is partially emptied and the pressure in it drops to a certain mark, the pressure switch will turn on the pump station. In the event that the crane overrides, the pump will still work for a while and pump water into the tank from the well or well, thereby increasing the pressure that was initially set. This scheme of operation helps to reduce the number of inclusions and shutdowns of the pump, which means it can increase its service life.

Membrane tanks for water supply are twotypes: vertical and horizontal. When the room allows the use of both these types, it is worth paying attention to the way of removing air from the rubber membrane. Vertical tanks collect air in the upper part, it can be easily vented by means of a nipple, which is available on any accumulator. Pressure tanks of horizontal type require the installation of an additional section, which includes a ball valve, an air nipple and a drain into the sewage system.

It is important to know how to properly mount a membrane tank for water supply. The installation instruction recommends following several important rules when installing the equipment:

1. The tanks must be installed in a place convenient for maintenance, where the accumulator is not subject to damage, vibration or atmospheric influences.

2. A safety group consisting of a safety valve, an air vent and a manometer should be installed on the outlet pipe from the tank.

3. The pipe connection to the tank must be made from the bottom.

4. Before putting the system into operation, it must be subjected to a hydraulic test. All membrane tanks for water supply pass through the factory pressure test, which is several times higher than the working one.

5. Before mounting the tank, check the membrane pressure with a pressure gauge.

Undoubtedly, the presence of a hydro accumulator is notrequired condition. In open systems, this equipment is unnecessary. However, for country houses with a closed system, membrane tanks for water supply are very relevant, because they protect their owners from many problems.
