摘要
二氧化碳压缩机组运行过程中出现的问题多是旋转失速故障，其危害是使机组很容易发展为严重的喘振，引起能量损失增大，整机效率下降。如果长时间旋转失速，将会使机组内部件因交变载荷产生疲劳断裂或因振动大发生磨损，给装置的长周期安稳运行带来隐患。分析二氧化碳压缩机的几次旋转失速故障，从机理上认识旋转失速问题，运用在线监测和离线监测手段诊断此类问题。
During the operation of the CO2 compressor train in the
chemical fertilizer plant of ZRCC,rotating stall happens most often,which may result in
destructive surgingAnd causes the loss of energy and decreases the efficiency of the
trainAlso if the rotating stall takes place for a relative long time,it will lead to either the
fatigue fracture of the inside parts of the train for alternating load or severe friction
from violent vibrationSo it has a bad influence on the longtime running of the plantHere
we collect the several cases of the rotating stall of the CO2 compressor trainBy
analysing and understanding the mechanism of this failure and using online and offline
monitoring,we can diagnoze such problems and put forward troubleshooting solutions
