摘要
概述了机械密封端面泄漏、端面偏磨、密封环碎裂、密封圈泄漏等常见早期失效现象,并分析了产生这些现象的原因,主要是设计制造问题造成的。同时介绍了延长泵轴机械密封使用寿命的一些有效措施,如选用密封可靠、寿命较长的摩擦付材料及静密封圈材料。
The paper summarizes the early failure phenomena such as mechanical seal face leakage, terminal face lopsided wearing, sealing ring disintegration and seal ring leakage and analyzes the reasons for these phenomena, which are mainly due to the design and manufacture problems. Several effective measures for extending the service life of pump shaft.Mechanical seal are recommended such as selecting reliably sealed and longer-lived friction materials and static seal ring materials.
