摘　　要：依据三要素设计方法及相关经验公式,对大流量无堵塞旋流泵主要结构参数的尺寸进行初步确定,用ANSYS CFX软件对初始设计的旋流泵进行外特性预测后发现,工况点处扬程仅达到设计扬程的77.1%,效率高出设计效率的24.2%。对主要部件叶轮外径D 2、宽度b 2和包角ψ等进行逐步优化,得到较优化的旋流泵模型,该泵工况点处扬程高出设计扬程3.2%,效率高出设计效率30.5%。为了验证模拟计算的准确性,对实体旋流泵进行了清水输送实验,工况点处实验扬程高出模拟扬程0.7%,实验效率高出模拟效率6.4%。In this paper,based on the three-element design method and related empirical formulas,the main structural parameters of the large flow non-clogging vortex pump are preliminarily determined.After predicting the external characteristics of the initial designed vortex pump with ANSYS CFX software,it is found that the head at the working point only reaches 77.1%of the design head,and the efficiency is 24.2%higher than the design efficiency.Then,the outer diameter D 2,width b 2 and wrap angleψof the main components of the impeller are gradually optimized to obtain a more optimized vortex pump model.The head at the pump operating point is 3.2%higher than the design head,and the efficiency is 30.5%higher than the design efficiency.In order to verify the accuracy of the simulation calculation,the water transportation experiment of the vortex pump was carried out.The experimental head at the working point is 0.7%higher than the simulated head,and the experimental efficiency is 6.4%higher than the simulation efficiency.
