摘要(Abstract)：

对应用喷水推进混流泵可控速度矩设计法设计的重负荷混流泵进行了试验研究,目的是探索并完善可控速度矩设计方法。试验结果表明,运用可控速度矩法设计的混流泵具有较高的效率及优良的汽蚀性能,不足之处在于工况点把握不准,这是下一步完善的主要方向。
A mixed-flow pump designed based on controllable velocity moment design method is researched by testing.The test purpose is to explore and consummate the design method.The test result shows that the mixed-flow pump designed by this method has high efficiency and cavitation performance.The shortage is that the design point is not held and it will be perfected by the next step.
