介绍了ZBM750型轴流泵水力模型的设计及试验研究,通过取稍大的轮毂比dh,增加轮毂侧的叶栅稠密度l/t和外缘翼型安放角,达到了良好的效果。结果表明:该模型具有效率高、高效范围宽、过流量大、抗汽蚀性能好、工艺性好等特点,可以推广应用。 This paper introduces the design and experimental research on the hydraulic model of ZBM750 axial-flow pump, and achieves good results by taking a slightly larger hub ratio dh, increasing the hub density l / t at the hub side and the mounting angle of the outer edge airfoil. The results show that the model has the advantages of high efficiency, wide range of high efficiency, large over flow, good anti-cavitation performance and good processability, which can be applied widely.
