摘要
针对山西省农村超深井提水困难及泵行业的现状,研究基于机械串接和绕组电气串接的方法,采用潜水泵单吸对置式多级离心式的方法与多级泵差压活塞式轴向力平衡装置技术,成功解决了小井径超深水位提水的技术难题。
Considering the difficulty of drawing water from extra-deep well and the status of pump industry in Shanxi rural area,the method basing on mechanical series connection and winding electric series connection was studied.Taking the water pump single suction opposed multistage centrifugal methods,through impeller opposed arrangement,the technical difficulties of drawing water was solved successfully.
