Non negative pressure water supply equipment is connected with the water inlet pipe and water pipe network directly, the water in the water supply pipe network residual pressure driven press equipment inlet pipe, pressure pump equipment continue to pressure in the water on the basis of residual pressure, the water pressure is increased to the user when the required pressure to supply water to the water pipe network; when the user uses more water than the water supply pipe network when the quantity of water inlet pipe, pressure drop, when the equipment inlet pressure reduced to absolute pressure is less than 0 (or set of network protection pressure), automatic start working pressure prevention and control device, the equipment running status adjusted until the equipment shutdown standby, ensure that the water inlet pipe network pressure no longer and reduce the adverse impact on the water network; when to restore the water supply capacity of tap water pipe network, water inlet pipe pressure back to protect the pressure above, equipment automatic startup, normal water supply; when the water pipe network residual pressure to meet user requirements for water supply, equipment automatically enter the sleep state, by the water pipe network directly to the user equipment supply, automatic recovery operation of water supply is insufficient; when the user does not need water or water is very small, automatic shutdown device enters dormancy The state, by the small flow regulator in equipment outlet side of the pressure tank to maintain the number of users of water and pipe network Water Leakage, users of water stabilized pressure tank can not maintain the water supply pipe network pressure required, Automatic wake-up, restore the normal operation of. Make full use of the residual pressure of tap water pipe network in the process of equipment operation, always does not adversely affect the water pipe network and the maximum to meet customer needs, reduce water consumption, to achieve the optimal operation of water supply system.
