摘　　要：依据我国村镇供水现状,分析了平坦的较小管径村镇供水管道中水锤发生的危害及水锤计算方法。重点讨论了水泵全特性曲线对小管径长距离平坦管道水力过渡过程的影响,并以我国南方某村镇泵站水锤计算为实例,得出相应的结论供同类工程水锤分析计算参考。According to the present situation of water supply in villages and towns,the harm of water hammer and its calculation method for small-diameter and long-distance delivery pipe in flat area were analyzed. The effect of the compete characteristic curve of the pump on the hydraulic transition process of the pipeline was discussed,and the water hammer calculation of one village pump station in south of China was verified,which provided a reference for the analysis and calculation of the water hammer in similar projects.

关 键 词：水锤 水泵全特性曲线 等扬程曲线 等转矩曲线
