摘要(Abstract):

将泄漏介质视为不可压缩流体,对其进行力学分析,得出了泄漏介质的流量和压力降等表达式。根据泄漏介质的密封条件,分析了软填料密封行为的两个典型状态,给出了软填料可靠密封的静态准则和动态准则。
Leaking medium is regarded as liquid of non compression,its flux and pressure drop are derived by mechanical analysis.According to sealing condition of leaking medium,static criterion and dynamic criterion are given by analysis of two typical sealing behaviors.
