长距离高扬程多级加压输水管道水锤防护工程实例

Water hammer control engineering case in high-lift,long-distance and multi-stage pressurized water transmission pipeline

长距离高扬程输水管道水锤防护难度大,极易造成运行事故。根据长距离高扬程输水管道系统的特点并结合西北地区某县长距离输水工程,采用多级加压、各级泵站之间独立计算的方法,讨论了此类工程水锤防护方法,可为同类工程提供参考。

The water hammer control was difficult in long-distance and high-lift water transmission pipeline, which caused operational accident easily. Combined the characteristics of long-distance and high-lift water transmission pipeline system with the long-distance water transmission project in a county in northwest area, the water hammer control method of this kind of project was discussed adopting multi- stage pressurization and independently calculation method between pump stations. It could provide reference for similar engineering project.
