The research results show that the steam inlet pressure and water inlet temperature are the main factors which affect the lifting-pressure performance; the steam injector have the characteristics of self-adaptive outlet pressure and constant outlet flow rate; the theoretical maximum lifting-pressure coefficient calculated could be high as 14 and the experimental value is 3.0, which could be high as 1.5 even if the water inlet temperature is high as 95℃. The noise of steam injector could be induced from 80db to 50db.
