Analysis of the application advantages and disadvantages of the five major refrigeration compressors

At present, semi-hermetic piston compressors are mostly used in the cold storage and freezing and refrigeration markets (commercial refrigeration and air conditioning are also useful, but they are relatively less used now). The semi-enclosed piston cold storage compressor is generally driven by a four-pole motor, and its rated power is generally between 60-600KW. The number of cylinders is 2-8, up to 12.

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="" />
