汇总了低比速离心泵优秀水力模型资料,通过回归分析和大量的计算,提出了低比速离心泵规范化设计方法和几何参数计算公式。对4种不同低比速实型离心泵进行了计算。计算结果表明,在这些几何参数中。叶轮出口直径D2 计算相对误差为0．64％,进口直径D0误差为1．63％,叶轮出口宽度b2误差为3．2％。这种方对低比速离心泵设计和研究具有实际意义。
Summarized the low-speed centrifugal pump excellent hydraulic model data, through regression analysis and a large number of calculations, proposed low-speed centrifugal pump standardization of design methods and geometric parameters of the formula. Four different low specific speed centrifugal pumps were calculated. The calculation results show that among these geometric parameters. Impeller exit diameter D2 calculated relative error of 0.64%, inlet diameter D0 error of 1.63%, the impeller exit width b2 error of 3.2%. Such a square on the low specific speed centrifugal pump design and research of practical significance.
