摘要
惠南庄泵站是南水北调中线工程总干渠唯一的一座大型加压泵站,是北京段实现管涵加压输水的关键控制性工程,也是中线工程的标志性建筑。泵站为大(Ⅰ)型Ⅰ等工程,单机容量大,特征参数变幅大,机组采用变频调速运行,调速范围大,运行工况复杂,技术难度高,国内外没有可参照的工程实例。现结合工程特点着重对大型、高扬程水泵机组的选型及运行匹配等主要技术问题进行分析研究。
Hui-Nan-Zhuang Pump Station is the only large-scale pressurized pump station along the main canal of the Middle Line Project of Southto-North Water Diversion and the key control project for water transfer by pressurized pipe culvert of Beijing section, and it is also the typical building of the Middle Line Project. The pump station is the 1st class project of big Ⅰ type with big unit capacity and wide range of various characteristic parameters, the frequency converter and speed regulation with broad range applied, complicated operating conditions, high difficulty of technology and no example can be referred to both domestic and overseas. This article combining the project characteristics study and analysis the key technical issues about the type selection and operating match of the large-scale pump unit with high head.
