摘要(Abstract):

对双螺杆制冷压缩机的转子啮合间隙、内容积比、注油量以及吸气流速等进行试验研究,得出了性能随间隙、内容积比、注油量、流速等变化的关系。研究结果表明,在一定运行范围内,啮合间隙增加0.01~0.02mm,性能下降1.5%~3%;制冷工况下内容积比选在2.6、吸气流速在9m/s时,压缩机能够获得较好的综合性能;回油量达到吸气质量流量的3%时性能最佳。
An experimental test rig of oil injected twin screw compressor is built in order to investigate key influencing factors such as the mesh clearance,Vi,oil-injection quality and inspiration speed on the performance of twin Screw Compressor. Experiment results show that within certain working conditions,the performance decreases by 1. 5 ~ 3% as the mesh clearance increases by 0. 01 ~ 0. 02 mm. Performance in cooling is desirable when the Vi is set at 2. 6 and the suction flow rate at 9m / s. And when the oil-injection quality is equal to3% of the refrigerant quality,the compressor could reach its optimism performance.
