离心泵几何参数对扬程综合影响的灰色理论分析

离心泵几何参数对扬程的影响,应当侧重于综合影响的研究。采用灰色理论分析了离心泵几何参数对扬程的综合影响,通过大量计算提出了这些参数对泵扬程的影响排序结果。计算结果表明,在这些几何参数中,叶轮出口直径对扬程影响最大,叶轮出口宽度影响最小,进口直径、叶片出口角和叶片数依次地位于它们之间。这种方法对其它工程项目方案的研究具有重要的实际意义。

Grey Theory Analysis of Synthetic Influence of Geometrical Parameters of Centrifugal Pump on Delivery Lift

In the research of the influences of geometrical parameters of centrifugal pump on the delivery lift,particular attention should be paid on the research of synthetic influence.Grey theory is adopted to analyse the synthetic influence of geometrical parameters of centrifugal pump on the delivery lift,and the order of these parameters is also offered after a lot of calculation in this paper.The calculating result shows that impeller outlet diameter exerts more influence on the delivery lift in these parameters,outlet width exerts less,inlet diameter,vane outlet angle and vane number are between them successively.This method has practical significance for the research of other project programs.
