【摘要】 介绍了与机械密封面积比有关的几种主要失效模式，并提出考虑主要失效现象的临界面积比。根据临界面积比的大小，可以判断所选用的机械密封面积比是否合理，并进一步来确定该机械密封的合适面积比。更多还原

【Abstract】 Some important failure modes relatedto the area ratio (balance ratio) of mechanical face seals are introduced, and also thecritical area ratio considering main failuresof mechanical face seals are presented. According to the critical area ratio the selectedarea ratio can be distinguished between thereasonable and unreasonable, and the suitablebalance ratio of mechanical face seals canbe further determined.更多还原
