摘要
在核工业领域,真空技术被广泛应用。在处理含有放射性的有毒有害物质时,真空装置安装在热室内,操作与维修需尤为谨慎。为了实现真空装置的有效运行、便捷维护以及提高真空装置的可靠性,对其进行适应性设计显得尤为重要。本文基于热室的基础背景,介绍了可以远程操作的真空装置自动平移门、在热室外远距离布置的真空系统、金属真空密封技术、可远程更换的电机结构和耐辐照材料选型等关键要素的设计要点,为同类真空装置的设计提供科学依据与实践指导。
Vacuum technology is widely used in the field of nuclear industry.When dealing with vacuum devices containing radioactive and toxic and hazardous substances,it is particularly prudent to operate and maintain them,which usually need to be placed in a hot cell.In order to realize the effective operation and easy maintenance of the vacuum device,and improve the reliability of the vacuum device,it is particularly important to carry out adaptive design.Based on the basic background of the hot cell,this paper introduces the design points of the key elements such as the automatic sliding door of the vacuum equipment that can be operated remotely,the vacuum system arranged remotely outside the hot cell,the metal vacuum sealing,the motor structure that can be replaced remotely,and the selection of radiation-resistant materials,which provides scientific basis and practical guidance for the design of similar vacuum devices.
