摘　　要：介绍了离心式涡轮冷压缩机的国外应用情况。根据中国科学院等离子体物理研究所EAST超导托卡马克氦低温系统当中过冷槽的设计制冷量,进行冷压机的整体结构设计,叶轮分析加工,轴承电机选择,并进行试验性加工。通过室温下测试,符合转速和稳定性要求。The application of centrifugal turbo cold compressor of the world was described. According the capacity of the helium refrigerator for the EAST superconducting Tokamak, centrifugal impeller of cold compressor was analyzed and manufactured, the bearing motor selection for cold compressor and experimen- tal machining were conducted. According to the test at room temperature, the rotational speed and stability to meet the requirements.
