基于几何与载荷参数耦合的轴流泵优化设计
Optimal design of axial flow pump based on coupling of geometric and loading parameters
摘要
Abstract
In order to improve the comprehensive performance of axial flow pump,on the basis of ex-perimental verification of the accuracy of numerical calculations,the inverse problem design method was adopted.Taking the efficiency and head under the design condition as optimization objectives,combined with the orthogonal experimental design method,the multi-objective optimization of vertical axial flow pump with the specific speed of 1 321 was carried out.The research results show that the geometric parameters(the number of blades B,the leading edge flange position Ls of the blades,and the trailing edge flange position Ts of the blades),and the loading parameters(the leading edge load value LEs of the blades at the flange,the leading edge load value LEh of the blades at the hub,and the slope Kh of the middle straight line at the hub),all have a significant influence on the energy charac-teristics of the axial flow pump.The hydraulic efficiency and head of the optimized axial flow pump model are 85.58％and 4.356 m,respectively,which are 1.36 percentage points and 0.877 m higher than that of the original model.The more uniform flow field in the optimized model impeller is the fun-damental reason for its performance improvement.This study can provide guidance for the design opti-mization of similar type of axial flow pump.关键词
