Discussion on Precaution Measures for Cavitation Erosion of Centrifugal Cryopump in Air Separation Unit
As an important component of the air separation unit,the stable and reliable operation of the centrifugal cryopump is of great significance for ensuring the continuous gas supply of the air separation unit.Among them,prevention of cavitation erosion is particularly important for the operation of the centrifugal cryopump.At present,literatures on precaution measures for cavitation erosion of centrifugal pump mainly focuse on structure optimization and operation maintenance.As the suppliers of air separation unit,we are familiar with the characteristics of cryogenic liquid.This article discusses precaution measures for cavitation erosion of centrifugal cryopump from four aspects:process organization,layout and piping;equipment procurement;control logic and operation,essentially avoiding the cavitation erosion of centrifugal cryopump.
