摘　　要：在长距离、多起伏、大流量的压力管道输水系统中,中下游通常涉及到多条配水管线,各种配水特性必然存在差异性,用水量、用水时间、地理空间等差异性因素先天存在。各支管在配水时的过渡过程显著影响着主管与其他支管的流量变化和压力变化,这些变化可能引发管线水锤现象。本文从理论研究与实验研究等方面分析瞬态特征与管线压力波动的关系,提出一种多阀联控技术。研究表明,该技术能够解决管线压力波动现象,并消除管线弥合水锤问题。In the long-distance,multi-fluctuation and large-flow pressure pipeline water delivery system,the middle and lower reaches usually involve multiple water distribution pipelines.There must be differences in various water distribution characteristics,and differences in water consumption,water use time,geographical space and other factors are inherent.The transition process of each branch pipe during water distribution significantly affects the flow and pressure changes of the main pipe and other branches,which may lead to the phenomenon of pipeline water hammer.In this paper,the relationship between transient characteristics and pipeline pressure fluctuation is analyzed from theoretical research and experimental research,and a multi-valve joint control technology is proposed.The research shows that this technology can solve the phenomenon of pipeline pressure fluctuation and eliminate the problem of pipeline bridging water hammer.
