国家同步辐射实验室储存环磁铁与电源系统冷却水系统的恒温改造

Reformation of constant temperature cooling water system for magnets and power supply system of electron storage ring in National Synchrotron Radiation Laboratory

针对国家同步辐射实验室储存环磁铁与电源系统冷却水系统的恒温工艺要求和连续运行特点进行了恒温改造:采用冷水机组和冷却塔间接供冷技术,运用PID控制流程理论,并采取一定的节能措施。通过调节电动三通阀可将冷却水温度控制在(20～25)℃±1℃。

Aiming at the constant temperature technology requirements and continuous operating characteristics of the system, executes the constant temperature reformation, adopting water chiller units and cooling tower indirect cooling technology, PID control theory and some energy conservation measures. After reformation, the cooling water temperature can be controlled within （20-25）℃±1℃ by adjusting electric three-way valves.
