This paper specified the fouling, corrosion, deformation of the impeller fracture occurred in assembly centrifugal compressors. Firstly, the impeller fouling, volute fouling and corrosion of flow channel was stated. Then its forming reasons were analyzed. Finally, the solving measures for relevant problems were pointed out. The improved measures extend the unit run cycle from 1500h to 8000h, which improves the reliability of unit operation and extends the using life of compressor.
