What is the top automatic constant pressure water supply equipment?

    Constant pressure water supply equipment using pneumatic water supply. The use of sealed tank, the use of high-pressure gas tank water pressure to achieve the purpose of water supply. The order of specific work is to pump water through the check valve into the tank, so that the gas tank is compressed, the pressure gradually increased. When the pressure reaches the specified limit, the electric contact pressure gauge stops the pump automatically through the control cabinet. The water pressure in the equipment is higher than that of the outside pipe network. When the water level in the tank drops and the expansion pressure of the gas in the tank is reduced to a specified lower limit position, the electric contact pressure gauge causes the pump to start again through the control cabinet. So repeatedly, so that the water supply equipment. When the gas tank is insufficient, the valve can automatically supply air.
