一般机泵的口环是怎么测量的，测量方法是什么，

Reply #22018-09-01

外径用游标卡尺、内径用内径百分表或使用内卡钳跟卡尺或带表内卡钳等。多测几个位置，判断是否椭圆了。

泵壳或者导叶上的口环测量内径，叶轮上的口环测量外径，看内径和外径的差值，再除以2就是单边间隙，具体数值可以泵的维修手册上肯定会有的，也可参照API610，小泵、使用温度不高的泵、单边间隙0.15~0.3mm；稍大的泵、使用温度较高的泵、要求不精密的泵可以在0.3~0.5mm，再大的泵有的可以达到1mm以上。至于测量方法，看具体情况，游标卡尺，卡钳，内径千分尺等都可以，只要能测出数据来。

一般用游标卡尺，千分棍

游标卡尺和内卡结合:)
