机械密封失效原因

Reasons for mechanical seal being out-of-run

分析了机械密封失效的原因有:机械密封结构不合理,使用材料不正确,在应用中工艺条件不符合要求,安装不规范等。统计了机械密封损坏的各种情况,认为冷却水结垢是密封失效的主要形式。

The reasons why mechanical seal is out-of-run include that structure of mechanical seal is irrational,the material used is incorrect,the process conditions can not meet the requirements when it is applied and the installation is not standardized,etc.After all kinds of mechanical seal damaging are estimated,it is considered that the seal malfunction is mainly because of cooling-water scaling.
