摘要
本文以赞比亚卡夫拉夫塔供水工程为例,阐述了长距离输水管线中二次增压泵站选址的要点,着重研究了地形对水泵扬程和系统方案的影响。结合非洲实际情况,对系统进行水锤模拟,综合比选了防水锤型复合排气阀,水锤预作用阀与内胆式水锤消除罐的水锤防护效果。随着“一带一路”项目的日益增多,本文对于非洲地区类似原水输水工程具有借鉴意义。
This paper took Zambia Kafulafuta Water Supply Project in Africa as an example,expounded the key points of the site selection of the secondary booster pump station in the long-distance water transmission project,and studied the influence of topography on the pump head and system scheme.This paper considered the actual situation in Africa,and conducted the water hammer simulation.Water hammer compound exhaust valve,water hammer preaction valve,water hammer elimination tank were compared.With the increasing number of"The Belt and Road"projects,this paper is of reference significance for similar raw water transmission projects in Africa.
