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

the main engine of the air compressor is unbalanced. Check whether the power supply and wiring ports are loose, loose and tighten, check whether the voltage is balanced, check whether the wiring is tightened or pressed well, and tighten and press well.

Methods/Steps

loosening and tightening

check whether the power supply and wiring port are loose, and if the wires are not pressed tightly, the main engine of the air compressor will be unbalanced;

machine failure

screw air compressor host imbalance caused by current transformer or controller failure, troubleshooting method: can be judged by checking the three-phase voltage and motor current;

whether the three-phase voltage is balanced

check whether the three-phase voltage is balanced. If the voltage is unbalanced, the current will also be affected, which is easy to cause equipment failure;

check if the current is stable

check whether the current is stable. If the voltage is stable and the current is unbalanced, it is usually caused by motor failure.
