The non-negative pressure intelligent frequency conversion water supply equipment is a water supply equipment composed of a non-negative pressure device, a pump group and a control cabinet. The flow stabilizing device is a closed structure, and the closed flow regulator is a tank pipe network superposition (non-negative pressure equipment, the system equipment is connected in series to the place where the pressure of the municipal tap water pipe network is insufficient. The equipment detects the outlet pressure through a pressure sensor, compares the detected value with the set value and calculates the pressure value to increase value, determine the number of pumps put into operation and the output frequency of the frequency converter (reflecting the rotating speed of the motor and the pump) to conform to the water consumption curve to realize constant pressure. The non-negative pressure frequency conversion water supply equipment makes full use of the original pressure of the municipal tap water pipe network, does not generate negative pressure on the municipal tap water pipe network, replaces the old pool with a steady flow tank, reduces water pollution, and is a new generation of energy-saving products in the water supply field.
