山西省中部引黄工程水泵泵型优化研究

Research on Optimizing Pump Selection in Yellow River Diversion Projectin in Central Shanxi Province

首先阐明泵站工程作为一种提水排水或补给水源的水利工程,在水资源调配、跨流域引水、城市及工农业供水等方面举足轻重,是解决水资源分布地域差异的有效工程措施。其次指出水泵选型是高扬程泵站设计中的重要环节,并以山西省中部引黄工程为背景,通过调研及理论分析,提出了该工程水泵运行特点、结构类型,并对各方案进行了比较分析,以期对类似的长距离、高扬程及大流量供水系统的设计及水泵的选择提供新的思路。

As a common method adopted in water supply and drainage project and recharge sources project, pump station plays an critical part in water resources allocation, interbasin water diversion and water supply projects in city, industrial and agriculture： it is an effective measure in solving the problem of imbalanced distribution of water source in different regions; furthermore the selection of the pumps in high-lift pump stations is the key section. On the basis of the Yellow River diversion project in central Shanxi province, this paper studied the feature of the project and its operational mode, analyzed and compared different engineering proposals,so as to eventually open up a new thinking method to analogous projects with high-lift, long distance and high flow.
