摘　　要：为进一步提高某一型号输送易汽化介质高速离心泵的抗汽蚀性能,提出了带分流叶片的变螺距诱导轮的设计方案。入口叶片设计为具有较小液流角、叶片数为2的等螺距结构;出口叶片设计为具有较大液流角、叶片数为4的等螺距结构;前后叶片组合成一变螺距诱导轮。实验结果证明带分流叶片的变螺距诱导轮高速泵具有优越的汽蚀性能。In order to further improve the anti-cavitation performance of a high speed centrifugal pump transporting easily vaporized medium,a variable-pitch inducer with splitter blades is designed. The blade at inducer inlet is designed as an equal-pitch structure with small flow angle and 2 blades,while the blade at inducer outlet is designed as an equal-pitchstructure with large flow angle and 4 blades. These 6 blades are fit together as a variable-pitch inducer with splitter blades.The experimental results show that the high speed centrifugal pump installing a variable-pitch inducer with splitter blades has good anti-cavitation performance.
