大中型卧式机组泵房特点及选择探讨

Discussion on characteristics and selection of large and medium sized horizontal unit pump station

卧式泵机组的结构形式较多,主要分为轴伸式和贯流式机组。贯流式机组又分灯泡式、竖井式和潜水贯流式(含全贯流式)三种结构形式。本文结合江苏省内已建的大中型卧式泵站,根据卧式泵分类的不同,分别归纳其特点和型式,并列举其应用实例。最后,从扬程和流量两个角度,研究如何选择卧式泵房型式。研究成果可为类似工程设计提供参考依据。

The structure of the horizontal pump unit can mainly divided into axial extension type and cross flow type. And the cross flow type contains bulb type, vertical shaft type, and submerged flow type. In this paper, combined with the large and medium-sized pump stations built in Jiangsu Province, the characteristics and types are summarized according to the different classification of horizontal pumps. Their application examples are listed. Finally, the selection of the horizontal pump is studied from the two aspects of head and flow. The research results can provide reference for similar engineering design.
