摘要：
The guide vanes comprise two kinds of guide vanes which are alternatively placed around the angular direction. One kind of the guide vanes have longer length than the other kinds of the guide vanes at the region which is close to the surface of hub but have substantially same lengths the other kind of the guide vanes at the region which is close to the shroud. The leading edges of the second kind of guide vane locate in the further downstream of the pump axial direction than the fist kind of guide vanes.
