What is the reason for the overload of the water pump indicator?
Hello friend, pump overload shows that the water pump current increases, the power supply phase and water pump load becomes larger.
In this case, first check the frequency of the pump in the acceleration and deceleration time, to see how many seconds, 7.5KW10 seconds or so, 11KW 10 to 15 seconds, to see whether the peak water supply, low voltage and so on! Hope to be of some help to you!
If the power is normal:1, the pump is indeed overloaded (at work to see how much the ammeter indicates).2 、 the motor is out of order.3 、 the thermal relay is not adjusted properly or aging.
