尊村引黄一级泵站技术改造研究

Study on Technical Transformation of the Zuncun Yellow River Diversion First Stage Pumping Station

为适应黄河水含沙量大,淤积与冲刷变化引起的泵站实际净扬程变化大的特点,对尊村引黄一级泵站的水泵、流道、流检门、技术供水进行改造。文中介绍了技术改造方案的拟订、参数确定并对技术改造后的效果进行了测试分析。

In order to adapt the Yellow River＇s flow characteristics including large sediment charge and large change of the actual net pumping head caused by silting and scouring, the technical transformation on pump, flow passage, flow inspection door and technical water supply was conducted for the Zuncun Yellow River Diversion First Stage Pumping Station. The paper introduces the process of drawing up the technical transformation scheme and determining the pump parameters and analyzes the testing results of the transformation effect after finishing the technical transformation of this pumping station.
