Project Introduction


Product Overview:

Non negative pressure water supply equipment is a water supply equipment composed of a non negative pressure tank, a pump group, a control cabinet, a stabilizing tank, and pipe valve accessories. The equipment is connected in series to the area where the pressure of the municipal tap water pipe is insufficient. The equipment detects the outlet pressure through a pressure sensor, compares the detection value with the set value, calculates the pressure value that needs to be added on the basis of the original pressure of the municipal tap water pipe, determines the number of water pumps to be pushed into operation, and the output frequency of the frequency converter (reflected in the motor and water pump speed) to achieve constant pressure according to the water use curve. The non negative pressure frequency conversion water supply equipment utilizes 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 water tank with a non negative pressure tank, reduces secondary pollution of water use, and is a new generation of.
