摘要
一般在设计往复泵时，计算行程容积Ｖｈ和最大指示功率Ｎｉ时都取相对余隙容积系数λｖ＝１。为什么取λｖ＝１，什么情况下取λｖ＝１，是否合理，都未说清楚。本文针对此问题进行了讨论，并提出了在极限真空度下计算λｖ的方法和行程容积的方法。
When designing the reciprocating vacuum pump, calculating the stroke volume Vh and the max. indication power Ni,the co - efficient of the relative space volumeλv=1. As λv=1, what are the reasons and conditions, is that reasonable. In this paper,these questions are discussed, the methods calculating λv=1 and stroke volume in the ultimate pressure are given.
