| 中文摘要: |
| 介绍密炼机上辅机智能控制系统（PLC），探讨如何通过PLC程序对密炼机注油过程中的注油压力过低、注油管路堵塞、料位计异常、注油电动机故障等注油故障进行判断报警和防错。通过在PLC程序中设定“注油最长时间”复位功能和“注油超时阻料”功能，可以降低因注油故障导致胶料散料或过炼超温的风险，并可预防故障延续、批量胶料质量事故的发生。 |
| 英文摘要: |
| This paper introduced the intelligent control system of the auxiliary machine of internal mixer（PLC），and discussed how to use the PLC program to judge alarm and prevent oil injection faults such as low oil injection pressure，blockage of the oil injection pipeline，abnormal level gauge and oil injection motor failure during the oil injection process of internal mixer.By setting the “maximum oil injection time”reset function and “oil injection overtime blocking” functions in the PLC program，the risk of compound bulk material or overheating due to oil injection faults could be reduced，and the continuation of failures and the occurrence of batch of compound quality accidents could be prevented. |
