摘　　要：压缩过程中油喷入压缩腔,随着转子的不断旋转增加了油气混合气的压力,混合气通过空气端的排气口进入油气分离器,进行油、气分离。分离出来的油聚集于分离器的底部,通过分离器滤芯的压缩空气,经最小压力阀流到后冷却器,压缩空气经后冷却器的冷却后,再经压缩空气出口流到用气管网。Liquid is injected into the compression chamber in the compression process,as the rotor rotatescontinuously,it increases the pressure of liquid gas mixture,gas mixture goes into liquid gas separatorthrough the air vent in the end of air,liquid and gas are separated,the separated liquid gathered at thebottom of the separator,the compressed air after separator filter flow to chiller through the minimum pressure,after the cooling of cooler,the compressed air then flow to trachea net through the outlet.
