Large vibration of screw air compressor

Screw air compressor vibration reasons may be the following:

the deviation of the wheel center is large, which may be caused by the installation error, thermal expansion under the working state, deformation after bearing and uneven settlement of the unit foundation.

The bottom angle bolt is loose, if the bolt is not tight, it will also cause the air compressor to vibrate.

The rotor clearance does not meet the standard, which may be caused by rotor deformation or wear.

Insufficient supply of lubricating oil for the air compressor, or the oil filter has not been replaced for a long time, the poor working environment leads to blockage, and insufficient lubrication causes bearing wear and vibration.

The influence of condensed water, the condensed water with corrosive gas in the air will cause serious corrosion of the rotor, gas seal, diffuser and carbon steel air pipe, etc., resulting in the vibration of the air vortex.

Screw air compressor 2. four impeller welding parts cracking or impeller surface scaling will also lead to vibration. Cracking may be caused by improper welding process or material fatigue; scaling is caused by impurities such as dust or soot in the air entering the compressor and mixing with lubricating oil.

For the above reasons, you can try the following solutions:

find a professional air compressor maintenance engineer to readjust the wheel center to ensure that the deviation of the wheel center is within the allowable range.

Adjust and fasten the anchor bolts to ensure that the bottom angle bolts are fastened reliably.

Check the rotor for deformation or wear and repair or replace if necessary.

Check whether the oil supply regulating valve is fully open and increase the amount of lubricating oil; replace the new oil filter or clean the old oil filter to ensure smooth oil flow.

For the impact of condensed water, air filtration and drying can be strengthened to reduce the entry of corrosive gases and condensed water; at the same time, the rotor, gas seal, diffuser and carbon steel air pipes are regularly inspected and maintained.

For the problem of cracking or scaling of the impeller, it can be repaired by welding or replaced with a new impeller; at the same time, air filtration and fume treatment are strengthened to reduce impurities entering the compressor.
