长距离高扬程多起伏输水管道水锤防护的研究

Research on water hammer prevention in high-lift,hilly and long distance water transmission pipeline

长距离有压输水管道易发生水柱分离水锤危害,尤以高扬程多起伏管道水锤防护难度最大,发生水锤的可能性最大。根据长距离高扬程多起伏输水管道系统的特点和多年实践经验,提出此种管道水锤防护的重点是消除断流弥合水锤,并结合北方某市供水工程实例进行水锤防护优化和计算,提出有效的水锤防护措施。

The phenomenon of water column separation may occur easily and cause the water hammer in closed long distance water transmission pipeline, especially in high-lift, hilly pipeline. According to the characteristics of high-lift, hilly and long distance water transmission pipeline system and many years experiences, the reasonable and effective water hammer prevention measure was put forward. The calculation and optimization of this measure were carried out with practical engineering example of a municipal water supply project in one north city.
