Analysis and Research on Water Hammer Protection for Long-distance Pressure Water Conveyance Pipeline with Multi Branch

文章针对南水北调供水配套工程长距离多支线供水工程压力输水管道水锤防护问题,以某市长距离多支线供水工程为示例,使用水锤分析软件数值模拟方法,采用运动方程,连续性方程和能量方程,根据管道的布置原则,对水锤发生的各种条件,计算不同条件下的可能出现管道中的水锤压力,分析了水锤压力沿输水线路的变化,确定最大水锤压力及其位置,为长距离多支线压力输水管道水锤防护提供理论支撑和实践探索。

In the paper,water hammer analysis software numerical simulation method is used in discussion about water hammer protection for long distance pressure water conveyance pipeline with multi branch of the South to North Water Diversion Project water supply system.According to the layout principle of pipeline,the equation of motion,continuity equation,and energy equation are used to calculate the water hammer pressure in pipeline under different conditions.The variation of water hammer pressure along the water conveyance pipeline is analyzed to determine the maximum water hammer pressure and its position,that could provide theoretical support and practical exploration for water hammer protection in long distance pressure water conveyance pipeline with multi branch.
