Abstract:
At present,many circulating cooling water system of scientific instruments don't have automatic time delay closing system to close the circulating water cooler. A kind of universal time delay circuit,correlated with mainbody power supply,is designed. It can delay 20～30 minutes to shut off the power supply of the cooling water system automatically after the mainbody power is off. This improvement saves the working time and increases the working efficiency
Key words:
circulating cooling water,
time delay control,
circuit
摘要：
目前许多大型仪器的循环冷却水系统,都没有提供相应的自动化延时关闭装置,给工作带来不便。经过分析,将主机供电系统与循环冷却水供电系统进行关联,设计了联动电路。实现了正常关机,循环冷却水系统自动延时 2 0min后关闭。既节约了工作时间,又提高了工作效率.
