BESIII束流管冷却系统设计与实现

Design and implementation of cooling system for beam pipe of BESIII

根据BESIII束流管的结构特点、工作环境以及温度控制要求,设计了束流管冷却系统。系统关键部件冗余设计,并采用西门子可编程控制器,实现了系统的自动可靠运行,保证了束流管的连续长期工作。上位机监控软件通过OPC和可编程控制器进行数据传输,解决了复杂多主站通讯问题,并辅助可编程控制器进行控制。该系统结构合理,功能完善,控制精度高,能及时将束流管内部热量带走,严格控制束流管的内外壁温度。

Cooling system for beam pipe is designed, based on the properties of structure, the surrounding and the required temperature of beam pipe in BESIII. The main devices are double for spare parts, and siemens program logic control is used in the cooling system, which realize the reliability of the equipment and assure the system long time running. OPC is used to communicate between Upper computer and program logic control as the third-party communication protocol, which resolve the problem of communication for complex multi-station, the upper computer assist the program logic control to detect and control the equipment. The cooling system have reasonable structure , comprehensive function ,good precision; its can take away the heat from inner wall of beam pipe in time, and control the temperature on inner wall and outer wall in the required range.
