摘　　要：介绍了水锤现象、水锤的分类和各类型的特点以及水锤压力的计算,并得出关阀直接水锤的最大压力。结合已有的研究成果分析了影响水锤效应的主要因素:管材、管道布置方式、介质流速、切断阀门、泵后止回阀等附加的水锤防护设施以及水泵的转动惯量。针对影响水锤效应的因素,从设备管路选型、管道布置、附加水锤消除装置以及系统操作和控制4个方面提出了相应的防护措施。The water hammer effect and the definition, classification, characteristics of each type and pressure calculation of water hammer are introduced and the maximum pressure for valve direct water hammer is obtained. The main factors affecting the water hammer effect are analyzed based on existing research achievements, including pipe material, pipe arrangement, medium flowrate, cut-off valve, check valve after the pump as well as other additional water hammer protection facilities and the rotational inertia of the pump. In view of these factors, corresponding protective measures are put forward from the aspects of equipment and pipe selection, pipeline layout, additional water hammer eliminator and system operation and control.
