射流泵由于它具有结构简单、成本低廉、容易维护等优点,在矿山得到比较广泛的应用,如处理平巷、斜井掘进工作面的积水,清理井底水仓的泥浆等等。本文对以水为动力的射流泵的计算原理加以整理,并以梅山铁矿使用的周边吸水形式的射流泵作为应用实例。
Because of its advantages of simple structure, low cost and easy maintenance, jet pump has been widely used in mines, such as water treatment of roadways and inclined shafts, cleaning mud in the bottom silos and so on. In this paper, the calculation principle of water-powered jet pump is sorted out, and the jet pump with surrounding water absorption used by Meishan Iron Mine is used as an example.
