泵抽空时机械密封失效原因及防止失效方法

Losing Effects of Mechanical Seal and Its Preventive

泵在运转抽空时即产生各种力的作用。本文通过各种力的综合作用和计算,说明泵在抽空时密封失效原因,同时提出防止失效的改进意见。

The forces are acted on the mechanical seals as soon as pumps arestarted.Reasons for the losing effeets of seals are analyzed through calculationof the forces.Measures for proventing seal losing effective are advanced.
