Centrifugal air compressors have vibration protection systems to ensure that the air compressor rotor will not be seriously worn. The main factors affecting the vibration of centrifugal air compressors are:
1. The dynamic balance of the rotor is not good, mainly the wear and tear that occurs during the operation, including dust, rust and moisture;
2. Bearing and bearing pad wear;
3. The wear and corrosion of the rotor vibration detection area is particularly obvious when there is external sealing air;
4. Other peripheral factors that affect vibration:
4.1 is not good for alignment;
4.2 The main motor vibration is too large;
4.3 The influence of external high-power heaters, this situation occurs during air separation;
