为了获得良好的抗汽蚀性能，对磁力泵叶轮采取低汽蚀余量设计措施，同时配置变螺距诱导轮。
In order to get a good performance on preventing cavitation, the impeller of magnetic driving pump is designed in low-NPSHR method and variable-pitch inducer is installed.
但是，对诱导轮与首级叶轮之间的流动问题的深入探讨进行的不多。
A finite volume based software, FLUENT, to simulate the flow field in an inducer and the first stage impeller in the boiler feed pump under three different flow .
