①Motor bearing eccentricity; ② Mismatch between the inner and outer rings of the bearing; ③ Lack of lubrication; ④ Incorrect concentricity
The motor bearing is eccentric, the inner and outer rings of the bearing do not match, there is a lack of lubricant, and the concentricity is incorrect.

1 Liquid present in the circulating hydrogen 2 Severe surge in the compressor 3 Mechanical impurities carried by the circulating hydrogen 4 Failure of the compressor’s support bearings leading to rotor wear
Group owner, is your answer that it’s a plunger compressor?
