Measures critical jet velocity, velocity field distribution and effective limits of this suction-airflow under different conditions.
测量了该吸气流动在不同工况下的临界射流速度、速度场分布、有效作用范围。
The results indicated that in the two-blade impeller, the fluid mainly flowed along the suction side, the velocity is very small on the pressure side, and a typical jet-wake flow has been observed.
由测量结果可知：在双叶片叶轮内，流体基本沿叶片吸力面流动，叶片压力面上的相对速度较低，在压力面出口出现了速度很低的回流区，有明显“射流-尾迹”特征。
A new type of high efficient liquid-gas jet pump with ring-shape noozle and two-side suction gas is presented.
本文提出了环形双侧吸气新型高效液气射流泵。
Because the utility model is provided with the compressed air inlet and the jet nozzle, the energy consumption is low and the silk suction effect is favorable.
与现有技术相比，本实用新型由于设置了压缩空气进口和喷嘴，它能量消耗低、 吸丝效果好。
