摘　　要：结合某宇航产品试验用自复叠制冷系统项目案例,针对此系统因回温问题导致机组发生故障进行分析,并对原系统回油管路进行优化设计,通过具体实验测试,通过观察油回路视镜及回油量,结果表明优化后的回油管路设计合理,性能可靠,整个系统能实现顺利回油,延长了压缩机运行寿命,同时,使整个系统的试验可靠及稳定性得到极大的提升。Combined with the project of auto-cascade refrigeration system used in one aerospace product test, to analyzing the failure caused by the oil return problem, and optimized the oil return pipeline of the original system. Through the experimental tests,by observing the oil mirror and oil return amount, the results show that the optimized oil return pipeline is reasonable and reliable,and the whole system can achieve smooth oil return. The life of the compressor is extended, and the reliability and stability of the whole system are greatly improved.
