在爪型泵型线研究［１］的基础上，本文推导出该泵的理论抽速计算式，为了对爪形 转子的动平衡进行分析与计算，本文又给出了该转子的质心计算式。
Based on the study of claw-type pump profile [1], this paper deduces the theoretical pumping speed formula of this pump. In order to analyze and calculate the dynamic balance of claw rotor, this paper gives the calculation formula .
