Screw air compressor failure host imbalance

Screw air compressor host imbalance failure may be caused by a variety of factors, the following are some possible reasons and the corresponding solutions:

power issue:

voltage imbalance or large fluctuations in the power supply may cause the host to be unbalanced. Check whether the three-phase voltage is balanced to ensure that the power supply is stable.

Loose connections or uncompressed wires can also cause this fault. Therefore, it is necessary to check whether the power supply and wiring port are firm.

Motor problem:

motor current imbalance may be caused by motor winding or rotor problems, excessive motor internal losses, bearing wear, etc. These problems need to be judged by checking whether the three-phase windings of the motor are normal, and repaired or replaced in time.

Controller or current transformer failure:

if the controller or current transformer fails, it may also cause the screw air compressor host to be unbalanced. At this time, the working status of the controller and current transformer should be checked, and if necessary, replaced or repaired.

Piping and compressor component problems:

imbalance of the main engine may also be caused by poor sealing, loose pipe connections or loose compressor parts. Therefore, it is necessary to check the tightness of pipe connections and compressor components, and deal with leakage or looseness in time.

Filter problems:

filter clogging or contamination may also affect the balance of the air compressor. Regular cleaning of the filter to ensure its unobstructed flow is a way to solve such problems.

For the above possible causes, you can take the following measures to troubleshoot:

use a multimeter to measure the input voltage to ensure that the error of the three-phase input voltage is within 10%. If the input voltage is unbalanced, contact the power supply department to solve it.

Check the actual current, use a clamp-on ammeter to measure the actual three-phase current to ensure that the three-phase current is within the normal range. If the current is unbalanced but the voltage is normal, the contactor may need to be replaced.

Relevant parameters are calibrated in the control panel to account for possible current transformer detection faults.

Regularly clean the filter, check and replace the defective pipe connections and compressor parts.

If the above methods cannot solve the problem, it is recommended to contact professional maintenance personnel for further maintenance and diagnosis.
