摘　　要：低温装卸臂是实现超低温环境下液化气体装卸的关键设备,广泛用于液氨和二氧化碳等低温液体输送。本文以二氧化碳和液氨类装车装卸臂项目为背景,对二氧化碳、低温装卸臂的工作环境、设计要求及关键零部件设计进行了探讨。研究表明,通过合理的材料选择与结构设计,尤其是旋转接头、密封结构的优化,使得装卸臂能够在低温、高压环境中稳定工作,满足传输安全可靠的要求。Low temperature loading and unloading arm is a key equipment for liquefied gas loading and unloading in ultra-low temperature environments,widely used for the transportation of low-temperature liquids such as liquid ammonia and carbon dioxide.This article discusses the working environment,design requirements,and key component design of carbon dioxide and liquid ammonia loading and unloading arms projects.Research has shown that through reasonable material selection and structural design,especially optimization of rotating joints and sealing structures,the loading and unloading arm can work stably in low temperature and high pressure environments,meeting the requirements of safe and reliable transmission.
