摘要
在对现有单流道叶轮水力模型进行归纳总结的基础上 ,给出了用速度系数法设计轴面图时的各系数值。借鉴双流道叶轮平面图水力设计的方法 ,提出了改进的单流道叶轮平面图水力设计方法 ,改进方法较原方法简单 ,尤其便于编制 CAD软件。文中还介绍了新的流道断面面积变化规律和平面图流道中线方程 ,同时还给出了编程方法和设计实例。
An improved way of single channel impeller hydraulic design is discussed in this paper, it is more simple than the former design method, which is especially fit to program CAD software. Based on summing up many excellent hydraulic models of single channel impeller, it gives various kinds of coefficient values of axial section. Inspect the design way of plan hydraulic design of double channel impeller, it provides the new design way of plan hydraulic of single channel impeller. It introduces a new change ruler of section area and an equation of plan channel midline. At last, a programming way and an example of design are given.
