No negative pressure water control points: no vacuum technology. Systems and municipal water pipe network directly connected pressurized water for municipal water pipe network is not a negative pressure. When the municipal pipe network pressure to reduce or even without water, the pump unit can still work until the steady flow of water out of the time-varying amount of compensation in the emergence of a negative or a simple low-level control mode when the water pressure drops to the set of electrical contacts Automatic shutdown no negative steady flow of water supply equipment purchases after the lower pressure given automatically after boot runoff. When a power outage, water pump stopped working, water can enter the user network via straight lines. When an incoming call automatically turn the unit back to normal water supply. No negative pressure water control points: Pressure automatic compensation. The system resistance characteristics no negative steady flow water devices much money, the greater the flow when the larger non-negative steady flow of water supply equipment when the resistance price system. Can be automatically adjusted according to changes in the system set pressure water system, small flow of water when running at low pressure, with an increase in water consumption, according to the hydraulic characteristics of the system, gradually increasing the operating pressure of the system. Thereby maximizing power savings. No negative steady flow water plant, Changzhi no negative steady flow of water supply equipment, energy saving is provided by Rui Teng Teng Rui energy-saving equipment Anyang City Limited.
