埕北B平台锅炉控制系统是由程控器作为定时控制核心,利用步进马达实现时序的控制,同时通过中间继电器、定时器、温度开关和压力开关、行程开关和热保护继电器等元件构成系统逻辑控制,经常出现无法正常启动、无故障自动停机、程控器走时不准和停机后无法热启动等一系列问题。将锅炉控制系统改造成PLC控制后,原系统存在的问题均已彻底解决。 埕 North B platform boiler control system is programmed as the core of the timing control, the use of stepper motor timing control, while through the middle relay, timer, temperature switch and pressure switch, switch and thermal protection relay and other components constitute the system logic Control, often appear unable to start normally, trouble-free automatic stop, program-controlled walking time is not allowed and can not stop after the hot start and a series of problems. The boiler control system into PLC control, the original system problems have been completely resolved.
