黄河小北干流上应用大型潜水电泵泵站设计的特点

Design Characteristics of Large Submerged Pumping Station in Xiaobeiganliu Main Stream of the Yellow River

泵站作为提水工程在我国的农田灌溉、平原排涝、城市供排水等方面发挥着巨大的工程作用，产生了良好的社会效益和经济效益．目前多数泵站的设计按规范要求进行，厂房分为地上部分及地下部分，机组多为离心式水泵和常规轴流泉．随着科学技术的发展，直径大于900mm的大型潜水电泵正逐步应用于生产．因此，对泵站工程的设计也提出了一些新的要求．本文结合实际工程，在泵站布置、泵站的防泥沙、潜水电泵支撑、泵站厂房设计方面，提出应用大型潜水电泵泵站设计的一些特点．

Pumping station, as water-lifting structure, play a signicant role in farm irrigation, plain flood draining, and city water supply and drainage in our country. Currently, large submerged pumps greater than 900mm in diameter are applied in practice. In this paper,through an example,adesign charateristics of large submerged pumping station are presented.
