摘　　要：结合新滩口泵站技术改造 ,利用前置导轮消除或减轻轴流泵汽蚀以及因进口流态不良引起的水力振动 .装置模型试验结果表明 :装上前置导轮后 ,叶轮进口断面的压力变均匀 ,振动减小 。The effect of inducer installed in the entrance of the axial flow pump is tested in model stand. The result shows that with the installation of inducer the pressure distribution in the cross section of the inlet is uniformed, the vibration and cavitation are minimized and the hydraulic characteristics of the pump are improved as well.
