Causes and Treatment Methods of Main Engine Unbalance of Screw Air Compressor

What is the reason for the imbalance of the main engine of the screw air compressor and how to deal with it?

1, first check whether the three-phase voltage balance, if the voltage imbalance will directly lead to the current imbalance fault.

2. Check whether the motor current is balanced? If the three-phase voltage is balanced and the motor current is unbalanced, it is the problem of the motor.

If there is no problem in checking the three-phase voltage and motor current, it may be the current transformer or controller.

4. Check whether the wiring is tightened or pressed properly. If the wire is not pressed tightly, it will also cause current failure.

5. How to deal with this situation? The first is to use the jaw of the clamp-type ammeter to clamp any phase of the motor into the clamp, and then the current can be displayed. In this way, all the current can be measured to see what the reason is. If it is really impossible, we can only wait for our professionals to come to see the scene before processing.
