Water Pump VSD Variable Speed Drive 3AC 380V 4KW 5.5KW 7.5KW
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 frequency converter. After the microcomputer judges the calculation and compares with the set pressure, the device controls 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 water consumption of the peaks and valleys, and ensuring that the pressure of the water supply pipe network is constant to meet the water demand of the user.
