摘　　要：研究了双涡旋齿涡旋压缩机排气口的开设,完善了排气口的开设原则,确定了双涡旋齿全啮合齿形和非全啮合齿形的排气口理论开设区域和可用开设形状,分析了双涡旋齿涡旋压缩机排气过程中排气腔容积、排气口开启面积和排气口气速等参数的变化规律。结果表明:与单涡旋齿相比,双涡旋齿排气口形状更为复杂但呈中心对称,而且在排气过程中排气口气速波动变化小。The design of discharge port for twin-wrap scroll compressor is studied, the principle of designing discharge port is improved,the theoretical regions and the usable shape of discharge port for whole meshing wrap and part meshing wrap of twin-wrap are determined, and the variation law of discharge chamber volume, discharge port＇ s working area as well as gas velocity in discharging process for twin-wrap scroll compressor are an- alyzed. The study results show that the shape of twin-wrap＇ s discharge port is complicated and symmetrical, and the gas velocity in discharging process for twin-wrap is steadier than the single wrap＇ s discharge port.
