摘要
针对目前实验研究中出现对真空预冷和减压冷藏2种技术的混淆,文中从真空预冷和减压贮藏的基本原理和运行时系统负荷差异产生的根本原因上对2种技术予以区分。结合不同类型真空泵的使用特点和不足,对减压冷藏系统的真空部分进行了详细的设计校核。本文提供的设计和校核方法可为减压冷藏装置真空系统的选型设计提供参考。
Basic principle and primary cause of system loading difference were analyzed to distinguish vacuum pre- cooling from hypobaric storage. With use features and shortcomings of different vacuum pumps, detailed design verification was carried out to vacuum part of hypobaric storage system. The design and verification method given can provide a reference to the design of hypobaric storage vacuum system.
