双端面机械密封泄漏原因及改进措施

Leakage reasons of double-face mechanical seal and improvement measures

介绍了某型反应釜用带轴套整装式双端面机械密封的结构及工作原理,结合实际工况,分析了其失效原因(如O形圈材质选用不合理,搅拌同轴度偏大,密封面变形),提出了改进措施及使用中的注意事项。

The structure and working principle of self-contained double mechanical seal with a shaft sleeve for a reactor are introduced. The failure reasons are analyzed in combination with the actual work- ing condition. The is bigger, and the failure reasons include that O-ring material is selected unreasonably, stirring coaxiality sealing surface is deformed. The improvement measures and the matters needing atten- in use are proposed.
