扬州市现有排灌设施大都采用混流泵、轴流泵和圬工泵,但圬工泵效率低,原混流泵和轴流泵的扬程一般在4米以上,缺乏更低扬程的泵型,致使泵站的装置效率很低。针对这种情况,闸门式贯流泵应运而生。本文叙述了三种贯流泵的安装形式和前置式贯流泵的性能,强调了贯流泵在安装中的注意事项。
Most existing irrigation and drainage facilities in Yangzhou use mixed flow pump, axial flow pump and hydraulic pump, but the pump efficiency is low, the original mixed flow pump and axial flow pump head is generally more than 4 meters, the lack of lower head pump, resulting in Pumping station equipment is inefficient. In response to this situation, gate-type tubular pump came into being. This article describes the installation of the three kinds of cross-flow pump and the front-type tubular pump performance, emphasizing the attention of the installation of the cross-flow pump.
