Variable frequency constant voltagepumpIt refers to a water supply method in which the outlet pressure remains constant when the water consumption in the water supply network changes. The outlet pressure value of the water supply network is determined based on user demand. The traditional constant pressure water supply method is achieved through facilities such as water towers, high water level tanks, and pressure tanks.

Water supply principle

Variable frequency constant pressure water supply system based on pipe network water pressure(Or user water flow rate)To set parameters, the output frequency of the frequency converter is controlled by a microcomputer to automatically adjust the speed of the water pump motor, achieving closed-loop regulation of water pressure in the pipeline network(PID)To automatically stabilize the water supply system at the set pressure value: that is, when the water consumption increases, the frequency increases, the pump speed increases, and the water supply volume increases accordingly; When the water consumption decreases, the frequency decreases, the pump speed slows down, and the water supply also decreases accordingly. This ensures the water supply efficiency. Users' requirements for water pressure and quantity are met, while achieving the goal of improving water supply quality and efficiency,“How much water to use, how much water to supply”The use of this equipment does not require the construction of high-level water tanks or towers, and the water quality is free of secondary pollution, making it an ideal modern building water supply equipment.
