斜轴泵肘型进水流道型线设计浅析

Design and Primary Analysis of Elbow type water-in flow path for skew axial flow pump

针对某泵站工程实例，拟定肘型进水流道剖面基本尺寸，分别运用流速曲线递增法和流速直线递增法进行平面轮廓设计，通过对设计流道的特征断面尺寸数据进行分析，校核设计流道的合理性，并对两种设计方法的流道设计结果进行了比较。

Aim at a actual example of a pump station engineering, the basic section size of elbow type water-in flow-path is drew up, and the plane contour line was designed separately applying the method of incremental velocity curve and incremental approach to linear velocity, according to the characteristic section data, the author analyze the rationality of the designed flow-path, and compare the designed results of the two design methods.
