What is the principle of non negative pressure water supply equipment


    Non negative pressure water supply equipment is a direct connection, with the municipal water supply network in municipal pipe network residual pressure based on a series of pressure superposed water supply and ensure that the pressure of the municipal pipe network is not less than the set pressure protection (set pressure must be higher than the residential direct supply pressure requirements, generally not less than 1.2Kg) water supply equipment.


    Non negative pressure water supply equipment put into use, tap water pipe network water entering the water tank, the air in the tank from the vacuum eliminator out, until the water is filled, vacuum breaker automatically shut down. When the pressure of tap water pipe network can meet the water requirement, the system by the bypass check valve to the water supply pipe network directly; when the pressure of tap water pipe network can not meet the demand for water, the system pressure signal by a remote pressure gauge feedback to the inverter controller, pump operation, and adjust the speed of the constant pressure water supply automatically according to the amount of water, if the water pump to run frequency speed, frequency conversion start another pump operation. The water pump, if the tap water pipe network is greater than the amount of water pump flow, maintain the normal water supply system; water peak, if the tap water pipe network of water less than the pump flow, water tank water as supplement water to normal water supply, the air into the water tank by a vacuum breaker, vacuum tank is destroyed, ensure tap water pipe network does not produce negative pressure, peak water after returning to the normal state of water supply system. When the tap water pipe network of water, causing water tank level falling, liquid level detector signal feedback to the frequency conversion controller, automatic shutdown pump, in order to protect the water pump, water tank can store and release energy, to avoid the frequent start the pump.
