【摘要】：為了快速、高效地設(shè)計(jì)性能優(yōu)越的軸流泵,結(jié)合計(jì)算流體力學(xué)方法和基于環(huán)量的三元設(shè)計(jì)方法,研究了葉輪環(huán)量中心位置、葉輪出口邊環(huán)量斜率以及導(dǎo)葉進(jìn)口邊環(huán)量與葉輪出口邊環(huán)量比值對軸流泵性能的影響,并設(shè)計(jì)了一型水力效率超過90%的軸流泵。研究表明:葉輪環(huán)量中心從0.3倍葉片弦長移動(dòng)到0.7倍弦長,葉輪效率降低了1%,但是葉片低壓區(qū)面積大幅減小;葉輪出口邊葉頂環(huán)量與葉根環(huán)量的比值K從0.9增大到1.1,葉輪效率逐漸提高;導(dǎo)葉進(jìn)口邊環(huán)量與葉輪出口邊環(huán)量比值R從0.9增大到1.1,軸流泵效率逐漸降低。
[Abstract]:In order to design the axial flow pump with superior performance quickly and efficiently, the center position of impeller annulus is studied by combining the computational fluid dynamics method and the three-component design method based on the annular volume. The influence of the slope of the impeller outlet ring and the ratio of the inlet ring of the guide vane to the outlet ring of the impeller on the performance of the axial flow pump has been studied. A type of axial flow pump with hydraulic efficiency of more than 90% has been designed. The results show that the impeller ring volume center moves from 0.3 times blade chord length to 0.7 times chord length, and the impeller efficiency decreases by 1%, but the area of blade low pressure region decreases significantly. The ratio K of the impeller outlet tip and the impeller root ring increases from 0.9 to 1.1, and the impeller efficiency increases gradually, while the ratio R of the guide vane inlet and the impeller outlet edge increases from 0.9 to 1.1, and the axial flow pump efficiency decreases gradually.
