A diaphragm tank is needed to protect the engineering system from water hammer and fully ensure its quality work. After purchasing the equipment, you need to carefully consider , how to install the membrane tank so that it works without failures. The accumulator in the water supply performs several functions: it accumulates water supply, maintains the necessary pressure in the system, serves as a reserve for reducing the frequency of switching the pump on and off.
Without installing a membrane tank, the life of the pump is significantly reduced. In a system provided with a hydroaccumulator, water can be drawn even when the electricity is turned off. During the first start of the pump, the water chamber of the tank is filled with water. The greater the volume of water in the tank, the smaller the volume of air and the higher the pressure. Reaching a given indicator of pressure, which is necessary to turn off the pump, it is automatically shut off. As soon as the pressure in the system drops to an acceptable level, the water supply will immediately turn on. A pressure gauge is installed on the accumulator to check the pressure. It is also necessary to adjust the required range of equipment operation.
Before connecting the accumulator in The water supply system should:
Mounting on fasteners
The equipment must be measured and calculated by highly qualified specialist. From the accuracy of the calculations and measurements depends on the quality of the water supply system.
Years of experience using membrane tanks for water supply has shown that horizontal models are the best option. If you have a submersible pump connected, purchase and install vertical hydraulic accumulators.
Installation procedure for tank
Elements that affect the hydraulic resistance cannot be connected between the pump and the hydroaccumulator.
Install the membrane tank only at positive temperatures. For ease of pressure control, the air valve is installed in an accessible area. The same rule applies to the connection of the drain valve, the abutment and both types of fittings.
To avoid undesirable load on the unit, it is worthwhile to mount the pressure reducer after connecting the measuring meter. Mount the safety valve in front of the flow pipe.
Two shut-off valves installed in the system on both sides of the tank will help to avoid unforeseen situations. Install a drain valve in front of the accumulator.
Diagram of the operation of the membrane tank
When installation work is carried out according to the recommendations, it is necessary to adjust the operation of the mechanism:
If you purchased a tank with a removable membrane, after a while it can be replaced. To install a new membrane, first unscrew the bolts on the flange joint, and then remove the flange and the outdated membrane. Install a new one and re-tighten everything again.
If you took into account all our recommendations and installed the membrane tank in the water supply system at home, uninterrupted supply of water to the house is ensured for a long time.
