摘要
氦压缩机是超导磁共振成像(MRI)设备制冷系统核心部件,及时解决氦压缩机故障对保障超导磁体低温系统的稳定性至关重要.以Sumitomo F-70型氦压缩机为例,分析超导MRI氦压缩机的结构组成及功能原理,并对常见的氦压缩机故障提出维修思路及解决方法,通过制定规范化的故障维修策略,为其他型号氦压缩机故障提供参考,以提高临床技术保障质量.
Abstract
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.
