摘要

改变叶轮外缘与尾水管之间的间隙，获得良好的性能，通过CFD的商业软件CFX进行了仿真。本文对冲压焊接多级离心泵的流动进行了数值计算，对其性能进行了预测，研究了冲压焊接多级离心泵在空间中的变化对其性能的影响，得到了冲压焊接多级离心泵的合理空间范围。为冲压和焊接多级离心泵的设计提供了理论依据，在实际应用中提高了离心泵的性能，提高了泵的运行效率

The Effect of the Clearance Value of Impeller and Draft-tube for the Performance of Stamping Multistage Centrifugal Pumps

Change the clearance between the outer edge of the impeller and the draft tube to get a good performance, simulated by the commercial software CFX of CFD. The paper numerically calculates the flow of stamping and welding multistage centrifugal pumps, forecasts its properties, studies the changes which impact its performance in space, gets the reasonable scope of space for stamping and welding multistage centrifugal pumps. It provides a theoretical basis for the design of stamping and welding multistage centrifugal pumps, improves the performance of the centrifugal pump in practical application, increases the operating efficiency of the pump
