后湾水库灌区总干二级泵站机组选型分析

Selection of pump unit types of a two-stage pumping station of the Main Houwan Reservoir irrigation district

灌区运行要求泵站既能满足正常情况供水 ,又能满足向调节水库储水和从调节水库提水灌溉 .设计中应用系统功能理论对泵站的基本功能进行了定义、整理 ,分析了实现泵站功能的多种途径 ,选择了合理的机组方案 .

Irrigation district operation requires that pumping station not only satisfy normal water supply, but ensure the water reserves of adjustment reservoir and water lifting irrigation form the reservoir. By using system function methodology during designing, basic functions of pumping stations are defined and arranged. The several ways of realizing the functions of pumping stations are explored and discussed too. At the same time, applying system engineering theory, main specific property targets of all kinds of pumping unit scheme are explained and analyzed. After considering some factors, such as least expense, easy management, a reasonable scheme is selected at last.
