1、压缩量机械防泄漏设计机械密封的泄漏是由于多种原因引起，我们要具体问题具体处理。为了最大限度的减少泄漏量，安装机械密封时一定要严格按照技术要求进行装配，如果是动静环与密封腔的间隙太小，就要增大密封腔内径或减小转动外径，至少保证0.75mm的间隙。如果是摩擦副配对不当，就要更改动静环材料，使其耐温，耐腐蚀。这样就会减少机械密封的振动和发热。Mechanicalsealleakagewascausedbyavarietyofreasons,wewanttospecificprocessing.Inordert

4、机械密封的零部件、工器具、润滑油、揩拭材料要十分干净。动静环的密封端面要用柔软的纱布揩拭。（2）修整倒角倒圆。轴、密封端盖等倒角要修整光滑，轴和端盖的有关圆角要砂光擦亮。（3）装配辅助密封圈时，橡胶辅助密封圈不能用汽油、煤油浸泡洗涤，以免胀大变形，过早老化。动静环组装完后，用手按动补偿环，检查是否到位，是否灵活;弹性开口环是否定位可靠。动环安装后，必须保证它在轴上轴向移动灵活。机械密封介质泄漏的故障原因机械密封振动偏大。机械密封振动偏大，最终导致失去密封效果。但机械密封振动偏大的原因往往不仅仅是机械密封
5、本身的原因，泵的其它零部件也是产生振动的根源，如泵轴设计不合理、加工的原因、轴承精度不够、联轴器的平行度差、径向力大等原因。(1)assemblytoclean,brightandclean.Mechanicalsealofspareparts,instruments,lubricatingoil,wipingmaterialsbeveryclean.Forstaticringsealstowipingwithsoftgauze.(2)finishingchamferinground.Shaft,sea
