高压甲铵泵机封故障原因及改进措施

Causes and Improvement Measures of Mechanical Seal Fault of High Pressure Ammonium Methyl Pump

国产高压甲铵泵机封采用单端面集装式机械密封,密封冲洗水系统为API682 PLAN32。在甲铵泵单试过程中,主泵的驱动侧机械密封发生较大泄漏,通过对其泄漏故障原因进行分析,制定机械密封改造方案,成功解决了国产高压甲铵泵机封泄漏故障。

The domestic high pressure ammonium methyl pump adopts single end face packing type mechanical seal,and the sealing flushing water system is API682 PLAN32.In the solo run of ammonium methyl pump,the mechanical seal of the driving side of the main pump had a big leakage.Through analyzing the causes of the leakage,the mechanical seal remodeling plan was formulated,successfully solving the sealing leakage of the domestic high pressure ammonium methyl pump.
