Features of frequency conversion pump control cabinet:

According to the water level in the water tank (tank), the electromagnetic valve (or electric valve) is automatically controlled to control the water inflow of the water tank (tank), so as to ensure that the water tank (tank) is automatic.

Hold a certain amount of water for users to use.

3. Description of selection of variable frequency pump control cabinet.

The control cabinet of variable frequency pump is mainly composed of variable frequency control cabinet, pressure sensor and water pump. The frequency conversion control cabinet consists of circuit breaker, frequency converter, contactor, intermediate relay and PLC.

Selection principle of control cabinet system of variable frequency pump

(1) The pump head should be greater than the actual water supply height.

(2) The sum of pump flow should be greater than the actual maximum water supply.

③ Selection of control cabinet for variable frequency pump: The user can determine the model and quantity of the pump according to the water supply quantity and water supply height, and then select the control cabinet.

Frequency conversion of water pump is to adjust the speed of water pump motor, and the frequency is displayed on the controller. Therefore, in normal use, the water pressure of the water pump basically swings from side to side, while the frequency changes.
