波纹管机械密封一般O在高温介质O,的柔性石墨垫而非橡胶O型圈。

OO. API68O Type B 就是波纹管密封O的O型圈,介质--40O-76℃

O0. O手机上的,不方便查,印象中好像aO是一个温度,c是高温O柔性石墨。b是普通波纹管用型圈。明天上班以后查一下O有错误的再来改正

本帖最后由 asd6692569 于 2018-7-17 13:54 编辑 波纹管串联式双端面密封,PLAN54,泵外做的油站。 密封泄露的情况我也没有看到,是刚生产时候用了,之后一直闲置。 VIKING内啮合齿轮泵,设计温度300摄氏度,粘度30-100,介质沥青,转速180。后来现场介质改为有轻质油,粘度很低,存在介质气化可能,也已经发生,惰轮轴套磨损,月牙板存在点蚀,应该是气蚀。机械密封拆解检查密封面肉眼看着不错,摩擦副互吸能吸住,柔性石墨情况不好判断。基本情况就是这样

机械密封的泄漏点不仅仅是动静环结合面!!动环静环的O型圈也可能因选型或装不当造成泄漏!!!介质导致O型圈溶胀而泄漏的情况也是有的!!!
