Common failure and analysis of centrifugal air compressor

Common failure and analysis of centrifugal air compressor 1. Abnormal vibration and noise: ① Misalignment ② The compressor rotor is unbalanced ③ The impeller is damaged ④ The bearing is abnormal ⑤ The coupling is faulty or unbalanced ⑥ The sealing ring is bad ⑦ The oil pressure and oil temperature are abnormal ⑧ There is dirt in the oil Clean, wear out the bearing ⑨ Surge ⑩ The stress of the gas pipeline is transmitted to the casing, which causes misalignment ⑪ There is a machine working near the compressor<img src="{{media url=&quot;Common_failure_and_analysis_of_centrifugal_air_compressor.jpg&quot;}}" alt="" />
