【摘要】 通过对三个叶轮含沙量从０～８８ｋｇ／ｍ３的大量浑水试验，分析其水力性能曲线的变化规律，讨论了离心泵抽送含沙水流时的扬程、效率和流量之间的变化关系；分析了含沙量对离心泵能量特性的影响．为抽送含沙水流离心泵的设计和工作性能的预测提供了依据．更多还原

【Abstract】 After three centrifugal pump impeller being tested within the silt laden flow with sand content of 0 to 88 kg/m3, the variation pattern of hydraulic characteristics chart are alalyzed, the relstionship of the head, efficiency and discharge is discussed the effect of silt content on energy characteristics of centrifugal pumps is alalyzed. All of these have provide a basis for pump design and prediction of the characteristics of centrifugal pump operated in silt-laden water flow.更多还原
