噴射水泵是利用具有压力的液体(或气体)的流动来吸取或排出液体(或气体)。其作用原理是借助喷射水泵噴出速度很大的水流(或气流),使水泵中噴咀附近产生空气稀薄现象,造成低压,而將水吸入水泵中,并与工作水流混合排出泵外。最近502勘探队在某矿区勘探时,为了利用已被水淹沒的旧坑道进行地质调查,曾使用这种水泵进行坑內排水工作,获得了显著的效果。现將这一具体作法作一扼要介紹,并談談这种水泵在地质勘探工程中的进一步广泛应用问题。
Jet pumps utilize the flow of pressurized liquid (or gas) to draw or discharge liquid (or gas). Its principle of action is to eject the water (or air current) with a great speed by the jet pump so as to make the air thin near the nozzle of the water pump cause low pressure, and the water is sucked into the water pump and mixed with the working water to discharge the pump. In the recent exploration of a mining area by a 502-piece exploration team, it was used to carry out in-pit drainage work in order to use the old submerged tunnel for geological survey and achieved remarkable results. Now this specific approach to make a brief introduction, and talk about this pump in geological exploration project further widespread application.
