环形多喷嘴射流泵结构参数的实验研究

The Experimental Study on Compositional Parameters of the Annular Multinozzle Jet Pump

环形多喷嘴射流泵的被吸流体在射流泵内沿直线流动,特别适合于抽吸含有大量固体颗粒的混合流体,在大口径反循环钻井和河道清淤等工程中具有广阔的前景。通过大量的实验,研究了环形多喷嘴射流泵各结构参数对射流泵性能的影响,为合理设计这种泵提供了理论依据。

The annular multinozzle jet pump is especially fit to pump the mix liquid containing large amount of solid particles because the drawn liquid flows in one direction in the pump. It may be widely used in reverse circulation drilling in large diameter well and in removing the river mud. Through a serious experiments, the effects of each structural parameters of the pump on pump characteristics were studied. The study provided scientific basis for designing annular multinozzle jet pump.
