水喷射器的引射系数分析

The Ejecting Coefficient Analysis of Water Eiector

影响水喷射器引射系数的因素很多,包括面积比、工作压力、引射压力及出口压力等,本文运用变量全微分的方法推出了这些影响因素改变时对于引射系数影响的具体表达式,井通过计算数据,分析了这些因素的影响次序.这对于设计及运行喷射器具有十分重要的意义.

There are many affecting aspects of ejecting coefficient of water ejector, including area ratio, working pressure, ejecting pressure and outlet pressure with the method of variable total differential, the expres-sions of ejecting coefficient are obtained in this paper. The affecting sequences are also analysed. It is very impor-tant to design and operate water ejectors.
