Water Pump Vector Frequency Inverter 3AC 380V 45KW ~ 75KW

When the water supply automatic control system works, the equipment detects the pressure change of the water supply pipe network when the water consumption changes through the high-sensitivity pressure sensor installed on the water supply pipe network, and continuously transmits the changed signal to the inverter, and judges the operation and setting by the microcomputer. After the pressure is compared, the controller sends a command to change the frequency. The controller changes the speed of the water pump motor and the number of enabled pumps by changing the frequency, automatically adjusting the peak and valley water consumption, and ensuring the water supply pipe network pressure is constant to meet the user's water demand.
