Introduction:
VFD Variable Frequency Drive Electric Pump Motor Controller use today's advanced AC frequency control technology and microcomputer control technology, is made up of frequency converter (speed ), programmable controller or intelligent frequency control constant pressure water supply controller and introduction low voltage electrical apparatus , is the new energy saving water supply equipment positioning on the pump flow range.
Control cabinet take the pressure of system network transient changes as the stable parameter (Comparative positioning ),control the output frequency of converter by microcomputer. Automatic tracking and adjusting the pump speed; to achieve the closed loop regulation of system pressure PID, thus ensuring the pressure of end network is constant, so that the entire water supply system sustainable and efficient operation. When the water consumption increases, the inverter output frequency will be larger, the pump speed accelerate, the water supply increase; when the water consumption is reduced, the inverter output frequency is smaller, pump speed slow down, the water supply reduce, to ensure users' the water pressure and flow need. Using variable frequency constant pressure water supply type, do not need to build a high level water tank, water tower, the water quality corresponding not easy to get the second pollution.
Performance parameter:
Power of Control Motor: 15-110KW
Control Voltage: 380V
Number of Control Pumps: 1-5
