PID控制回路虽然理论上完全适用于窑尾喂料流量的控制,但是实际应用中,许多生产线在PID自动模式下,还不如手动模式下稳定。因此,许多PID回路都处于手动状态,形同虚设。为此,笔者结合多年调试经验,以国内某3 000t/d生产线项目为例,介绍PID各项参数快速整定的方法和经验。1窑尾喂料工艺流程简介窑尾喂料主要工艺流程包括从均化库底设备一直到窑尾入窑提升机。其中对喂料量有影响的部分如 Although the PID control loop is theoretically suitable for the control of kiln tail feed flow, in practice, many production lines are not as stable under manual mode as PID auto mode. As a result, many PID loops are manual and useless. To this end, the author combined with many years of commissioning experience to a domestic 3 000 t / d production line project, for example, describes the PID parameters of the rapid tuning method and experience. A Kiln Feeding Process Introduction Kiln Feeding The main process from the bottom of the homogenization equipment until the kiln into the kiln hoist. Which affect the amount of feed part of the
