The principle of it is: When the upper level is reached, the rotary valve and bin gate will start in turn to discharge. 其控制原理为:当上料位信号出现时,卸灰电机、闸板阀开始工作,进行排灰。
And when the time is up, it will stop the rotary valve and bin gate to finish the discharging process. 定时时间到,停止闸板阀和卸灰电机,排灰停止。定时控制是程序自动通过定时进行排灰。
