浅谈多级离心泵机械密封故障原因分析与处理方法

Analysis and Treatment of Mechanical Seal Failure in Multi Stage Centrifugal Pump

针对某化工企业某台多级离心泵的故障原因进行了分析。从机械密封、装配精度以及实际运行情况等方面入手,对长期易损坏问题进行了多角度分析。通过分析对比,找出了影响机泵运行周期和机械密封使用寿命短的主要原因,制定了相应处理措施,提高了机械密封的使用寿命,间接提高了机泵运行的周期,达到了良好的效果。

In this paper, the failure causes of a multilevel centrifugal pump in a chemical enterprise are analyzed. An analysis of the problem of long term damage is conducted from the mechanical seal, assembly precision and the actual operation and so on. Through the analysis and comparison, the main factors affecting the operation cycle of the pump and the short service life of the mechanical seal are found out, and some corresponding measures are taken, thus the service life of the mechanical seal being improved, the cycle of the pump operation increased and the good effect achieved.
