利用地下水资源,是靠水泵将水从深井内抽至地表面,流入预定场所作为生产、生活供水之用。然而深井泵叶轮级数的合理选择对节电有很大影响。因为深井水泵的动力,主要是消耗在每级叶轮的旋转抽水上,叶轮级数越多所耗动能就愈大,以保证有足够的扬程。深井泵叶轮全部浸在水中工作(要求水泵
The use of groundwater resources is based on the use of water pumps to pump water from deep wells to the surface of the ground and into the intended site for production and domestic water supply. However, reasonable selection of the number of deep well pump impellers has a great influence on energy saving. Because the power of the deep well pump is mainly consumed in the rotary pumping of each stage impeller, the greater the number of impeller stages, the greater the energy consumption, so as to ensure that there is sufficient head. Deep well pump impeller is fully immersed in water (required water pump
