超导磁共振氦压缩机结构功能与故障案例分析OACSTPCD

Helium compressor is the core component of the refrigeration system of superconducting magnetic resonance imaging(MRI)equipment,and timely resolution of helium compressor failures is crucial to ensure the stability of the superconducting magnet cryogenic system.Taking the Sumitomo F-70 helium compressor manufactured by Sumitomo Heavy Industries as an example,the structural composition and functional principle of the helium compressor for superconducting MRI were analyzed,and the maintenance ideas and solutions for common helium compressor faults were proposed.By developing standardized fault maintenance strategies,reference was provided for failures of other types of helium compressor,so as to improve the quality of clinical technical support.
