摘要
针对煤矿井下排水主水泵,为了实现吸入式离心泵的无底阀排水,分析了射流泵和真空泵的工作原理,在同煤集团的两个矿分别应用了不同的引水方式,通过降低系统吸上真空高度,从而实现了高效节能。
Focusing on the main pump in coal mines and to realize the drainage of suction centrifugal pumps without the bottom valve,the paper analyzes the working principles of jet pumps and vacuum pumps.Two water diversions are used in two cola mines of Datong Coal Group and high efficiency and energy saving are achieved by reducing the vacuum level of the system.
