采油平台中开式高压多级泵机封频繁泄漏的排除案例分析

Case Study on Frequent Leakage of Mechanical Seal of Open High Pressure Multistage Pump in Oil Production Platform

采油平台中开式多级离心泵使用一定周期后高压端机械密封泄漏,多次更换后并未解决问题,最短在更换2h后开始泄漏,设备不能正常使用,通过对离心泵的内部结构及故障现象的分析判断并经过一系列的改进改造,排除了高压端机械密封频繁泄漏的现象。

The mechanical seal at the high-pressure end of the open multi-stage centrifugal pump on the oil production platform leaks after a certain period of use,and the problem is not solved after repeated replacement.The leakage starts two hours after the replacement,and the equipment can not be used normally.Through the analysis and judgment of the internal structure and fault phenomenon of the centrifugal pump,and after a series of improvement and transformation,the frequent leakage of the mechanical seal at the high-pressure end is eliminated Phenomenon.
