Water-cooling system development and its high precision water temperature control for Anhui University Free Electron Laser & High Magnetic Field device

  • 摘要: 介绍了安徽大学正在建设的强光磁试验装置的整体布局,详细分析了装置的稳定运行对水冷系统的设计要求及难点,根据需求完成了整个装置的水冷系统设计研制,装置的水冷系统一共包含了两路独立的水冷机组系统,设计温度分别为(42±0.1)℃与(25±0.5)℃,并且可在一定范围内调节。装置水冷控制系统基于EPICS 框架开发,温度调节及控制功能通过PLC程序实现,PID参数配置通过PID调节器实现。控制系统的软件开发主要是在EPICS环境下实现对设备参数的设定和状态数据的回读,并将历史数据存入Archiver Appliances数据库中。试运行期间水冷控制系统的温度控制精度达到了(42±0.03)℃和(25±0.08)℃,符合设计要求,运行期间该系统稳定可靠,可以很好地保障装置安全稳定运行。
