摘要
建立了以效率和工作范围为主线的小流量旋涡泵的理论设计方法，并对ＸＷＢ－３／１３０和ＸＷＢ－１／１１０两台旋涡泵进行了试验研究．理论分析和试验结果表明：较大的流道面积Ｆ可以拓宽泵的工作范围，较大的径向间隙△ｐ和轴向单边间隙δα会降低泵的扬程和效率。
The theoretical design method of small-flow high-head vortex pumps is presented with objectives of efficiency and operating range, and the experimental study is also carried out on two vortex pumps XWB-3/130 and XWB-1/110. The theoretical analysis and experimental results show that larger flow area F can increase operating range, and larger radial clearance △ｐ and exial clearance δα can decrease head and efficiency of vortex pumps.
