求计算这个口环间隙

Reply #42019-03-08

一台冷油泵，口环直径d=115mm，则壳体口环与叶轮口环之间的更换间隙应为答案是 1.5mm，求怎么计算的？

Reply #52019-03-08

先查标准（API611）等标准，之后在标准间隙的基础上，根据实际情况（介质含颗粒情况，动静口环材质、泵悬臂长度、工况温度、叶轮径向力、转子跳动以及加工同轴度精度等因素）稍做调整

标准上面有多最小间隙的要求

API规定在于 115mm至 1.49.99mm旋转直径下的最小直径间隙为 1.43mm，至于更换间隙，要看间隙对效率的影响，好像是磨损 1.5倍就要换。不知道你这个 1.1mm怎么来的。

1.45mm，帮你算了，你这个 8.5mm怎么来的？是不是不同心车大了
