浅析二级泵站中水泵的调速节能

Analysis on speed adjustment and energy-saving of pump in secondary pumping station

对二级泵站的几种运行方式,即定速运行、变速恒压运行、变速变压运行,从能量消耗的角度上进行了分析,并指出了各运行方式的适用场合,同时探讨了二级泵站中水泵的一些节能运行方式。

The operation modes of pumps in secondary pumping station are analyzed from energy-consumption aspect, which contain operation modes with constant velocity, constant pressure variable speed and variable pressure and speed. The application soope of those operation modes are pointed out. In the end .some energy saving modes of pumps in secondary pumping station are discussed.
