摘　　要：在旋流泵流场计算及流场测试基础上 ,就旋流泵的结构参数对泵性能的影响进行了一系列试验研究 ,总结了以蜗壳无叶腔体积 V0 与叶轮体积 VI 之比 ZV 来设计旋流泵的方法 ,并由大量试验数据统计得到 ,当ZV=V0 /VI=3～ 5时可获得较好的水力性能。设计的几种旋流泵的效率比国内外同类产品提高了 3%～ 5 %On the basis of the measurement and calculation to the fluid field of vortex pump, the influence of pump structure on its performance was experimentally studied. A new method was developed in which the volumetric ratio of the vane less cavity to the impeller was used to design vortex pumps. According to the statistics of a number of experimental data, the authors believe that the pump can get a good performance in the ratioes between 3~5. The corresponding designs of several kinds of vortex pumps increase their efficiency by a factor of 3%~5% compared with the same kinds of pumps manufactured home and abroad.
