Intelligent non negative pressure water supply equipment

The intelligent non negative pressure water supply equipment relies on the pressure of municipal tap water during operation, superimposes the required pressure difference on the existing pipeline network pressure, and makes full use of the residual pressure in the pipeline network. The system automatically adjusts the number of running water pumps or adjusts the pump speed to achieve continuous high-efficiency operation. When the inlet pressure can meet the design pressure, the water pump enters a dormant energy-saving state. Therefore, it greatly saves operating costs and meets the requirements of national energy conservation.
