Non-negative pressure water supply equipment is a system composed of a non-negative pressure tank, pump set, control cabinet, pressure stabilizing tank, and pipe valve accessories. It is connected in series where the pressure of the municipal water supply pipe is insufficient. The equipment detects the outlet pressure via a pressure sensor, compares the detection value with the set value, calculates the required pressure increase based on the original pressure of the municipal water supply, and determines the necessary pressure. The system then controls the number of pumps in operation and adjusts the output frequency of the variable frequency drive (which regulates motor and pump speed) to achieve constant pressure in line with the water curve. The non-negative pressure variable frequency water supply equipment utilizes the original pressure from the municipal water supply, preventing negative pressure in the municipal water network, replacing old water pools with a non-negative pressure tank, reducing secondary water pollution, and serving as a new generation of energy-saving products in the water supply sector.
