Water Pump VFD Variable Frequency Drive 3AC 380V 11KW ~ 18.5KW

KD386 series constant pressure water supply

When the pressure of the pressure transmitter is the largest, the frequency of the inverter is the lowest, and the speed of the pump motor is the lowest. When the pressure of the pressure transmitter is the smallest, the frequency of the inverter is the highest, and the speed of the pump motor is the highest. The frequency of the inverter changes with the change of water consumption. After the PID adjustment parameters are modified, the pipeline pressure is always kept constant; even if the water consumption is a variable, the final pressure is constant.
