Ⅰ.Working principle:

Constant pressure water supply equipment adopts pneumatic water supply, and uses high-pressure gas and water pressure in the tank to achieve the purpose of water supply. It is mainly composed of three parts: pressure tank, water pump and electric control system. The specific working sequence is that the water pump presses the water into the tank through the check valve, so that the gas in the tank is compressed and the pressure gradually increases. When the pressure reaches the specified upper limit, the electric contact pressure gauge automatically stops the pump through the control cabinet. The water pressure in the device is higher than the external pipe network pressure, and the water is automatically sent to the water supply pipe network. When the water level in the tank drops and the gas expansion pressure in the tank decreases to the specified lower limit position, the electric contact pressure gauge makes the pump restart through the control cabinet. This is repeated so that the equipment does not stop supplying water. When the gas in the tank is insufficient, the filling valve can automatically fill the gas.

Ⅱ.Advantages:

Its outstanding advantages are that it does not need to build a water tower, small investment, less land, flexible layout, and fast completion and production. It adopts automatic water gas regulation, automatic operation, energy saving and automatic grid connection of tap water, can still supply water after power failure, and does not need to be cared for after commissioning.

Ⅲ.Scope of application:

Widely used in enterprise units, residential areas, schools, hotels, machine heads, rural areas, factories and other dense places of production, living, office water supply.
