文章从理论推导为基础 ,同时以 2 0Sh -6型水泵为例做了实际的推导计算。作者在其它型水泵做过多次推导和计算 ,误差精度都得到比较满意的结果。证明该种计算方法完全可以用于工程计算
The article derives from the theory as the foundation, and at the same time makes a practical deduction calculation with 20Sh-6 type pump. The author made many derivations and calculations in other types of pumps, the error accuracy has been more satisfactory results. Prove this kind of calculation method can be used in engineering calculation completely
