摘　　要：屏蔽泵因其独特的结构组成,在工业领域的应用越来越广泛,并发挥着重要作用,因此屏蔽泵的故障处理也日显重要。为了解决某石化厂苯乙烯车间SGM系列屏蔽泵振动大、现场噪声大、压力偏低等问题,现场对泵进行振动检测。通过频谱分析,发现屏蔽泵工作过程中存在着1倍频不平衡力影响,从而造成泵的异常故障,据此对泵转子进行不平衡校正,校正后的泵恢复正常运行。通过对屏蔽泵的故障进行分析,提出了合理的处理措施,为屏蔽泵的安全稳定运行提供了保障。Because of its unique structural composition,canned pumps are more and more widely used in the industrial field and play an important role,the troubleshooting of canned pumps is becoming increasingly important.In order to solve the problems of large vibration,large noise and low pressure on the SGM series shielded pump in the styrene workshop of a petrochemical plant,the pump was subjected to vibration detection on site.Through spectrum analysis,it was found that there was a 1 frequency unbalance force during the operation of the shielded pump,which caused abnormal pump failure.According to this,the pump rotor was corrected for unbalance,and the corrected pump returned to normal operation.Through the analysis of the failure of the canned pump,reasonable treatment measures were proposed to provide a guarantee for the safe and stable operation of the canned pump.
