Causes of big abnormal noise of screw air compressor vibration

In the previous advantages and disadvantages of the screw air compressor, it was said that compared with the piston air compressor, its stability is better and the vibration is relatively small, but in special cases, there will be large vibration. So what are the reasons for this?

1. The machine bolts are loose;

2. The oil filter is blocked without replacement for a long time;

3. The gap between the yin and yang rotors does not meet the requirements;

4. Large deviation of wheel center;

5. The bearing is worn;

6. Air compressor oil is insufficient.

Processing methods in turn are:

1. Tighten the loose bolts;

2. Replace the new oil filter;

3. Check whether the rotor is worn, and if it is necessary to repair it again, do dynamic balance check, etc;

4. Re-adjust the wheel center;

5. Replace the bearing;

6. Add lubricating oil;

the noise of the air compressor is also one of the common faults. The main reasons for the metal impact sound, friction whistling sound, etc. are mainly in the following aspects:

1. The intake valve is not completely closed or the large intake volume causes the check valve to vibrate;

2. Loose gear bolts;

3. Lack of oil during the operation of the air compressor;

4. The belt of the belt drive air compressor is loose and caused by slipping;

processing methods in turn are:

1. Adjust the intake valve;

2. Tighten the loose bolts;

3. Add lubricating oil;

4. Replace the three drive belts.
