Non negative pressure variable frequency water supply equipment

Product Overview:
The non negative pressure intelligent variable frequency water supply equipment is a water supply equipment composed of a non negative pressure device, a pump group, and a control cabinet. The stable flow device is a closed structure, and the closed flow regulator is a tank type pipe network stacked pressure (no negative pressure equipment, the system equipment is connected in series in the city where the pressure of the municipal water supply network 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 water supply network, determines the number of water pumps put into operation and the frequency converter output frequency (reflected in the motor and water pump speed) to achieve constant pressure in accordance with the water use curve. The non negative pressure variable frequency water supply equipment maximizes the use of the original pressure of the municipal white water supply network, and does not produce negative pressure on the municipal water supply network. Stable flow tanks replace traditional water tanks, reducing secondary water pollution, It is a new generation of energy-saving products in the field of water supply
