摘要
现有的两类一元理论离心泵叶轮水力设计方法存在试凑性工作量大或盖板形状不为简单曲线的缺陷。本文提出了符合一元理论的离心泵叶轮轴面流道过流断面的一种新的分布规律,并给出了按照此分布规律计算叶轮轴面流道过流面积的计算方法和公式。将其与传统的两类设计方法做了比较。
The existing two kinds of 1-dimensional centrifugal pump impeller hydraulic design methods have short comes of either large calculation or complicated boundary lines. This paper presented a new presumption about the formulation of the flow cross section forming line complying with the 1-dimensionl theory. It also gave the solution to locate the flow cross section and formulas to calculate the flow cross section area which is important to determine the boundary stream line. Comparison between it and the old methods was made at the end of the paper.
