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

Abstract:

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.
