液-液气射流泵的实验研究

摘要

Liquid-liquid & gas jet pump is a kind of li quid jet pump which can pump two-phase liquid and gas fluid.First,the principal s of liquid-liquid & gas jet pump and the deduction of the fundamental characte r istic equations are described in the thesis.The ratio of the gas in the jet-eli citing medium β (gas ratio)is used as a parameter.The fundamental character istic equations of liquid-liquid & gas jet pump are got through the characteris tic experiments.This equation can be applied to the liquid-liquid or liquid-ga s jet pump.The fields it is fit in are extensive and it can be used as the refer ence for engineering design.%液-液气射流泵是一种能同时抽吸液、气两相介质的液体喷射泵。本文首先对液-液气射流泵的工作原则以及基本性能方程的推导过程进行了论述，引入了表征引射介质中气相的体积流量比的参数β(含气比)，最后通过性能试验得到了液-液气射泵的基本性能方程。该方程还能够描述液-液和液-气两种射流泵的基本性能，适用范围广泛，可作为工程设计的参考。
