摘要
结合上海市长江引水三期工程取水泵站虹吸式出水管水力模型试验,分析了城市取水泵站虹吸式出水管的类型及特点,研究了影响虹吸式出水管虹吸形成的因素,提出了虹吸形成时间短的出水管布置修改方案。研究结果表明,修改方案有效地改善了虹吸式出水管的水力特性,提高了水泵运行的可靠性。
Experiments on hydraulic model of siphon-type water outflow pipe （SP） of water intake pumping station for the project of Yangtze River water diverting engineering, 3rd phase, were conducted. By this way the type and property of SP for municipal water intake was investigated, the factors influencing the formation of siphon inside the SP were researched and a corrected program of SP layout for tubes with shorter siphon formation time was proposed. The experimental results showed that the hydraulic characteristics of the SP improved evidently and so the operating reliability of the pumping assemblies increased.
