Causes of large vibration of screw compressor

There may be many reasons for the large vibration of screw compressors, including the following common situations:

the anchor bolts of the unit are loose or the rigidity of the frame is poor.

Poor alignment between compressor and prime mover.

Unbalanced compressor rotor or worn bearing.

There is friction inside the compressor or the gap between the rotors does not meet industry standards.

The unit pipeline produces resonance.

Excessive liquid or lubricating oil is sucked into the cylinder, which may be caused by insufficient oil supply or clogging of the oil filter.

The gap between the male and female rotors does not meet the requirements, or the rotor is deformed.

The clogging of the precision filter affects the normal passage of compressed air.

Intake valve not fully closed, check valve vibration, loose gear bolts or belt drive compressor belt slip, etc. may also cause vibration.

In order to solve the problem of large vibration of screw compressors, the above reasons can be investigated one by one, and corresponding solutions can be taken, such as tightening loose bolts, replacing worn bearings, adjusting rotor clearance, cleaning or replacing filters, adjusting intake valves, etc. In the maintenance process, it is recommended to consult a professional technician or contact the mechanic for adjustment and repair.
