摘要
气压机组是重催装置的重要组成部分,在装置正常运行时对来自装置反应器的富气进行压缩,机组运行转速高,对转速控制的精度和可靠性都要求很高。介绍了利用Triconex的ESD对重催气压机组进行转速控制,对程序进行了详细的逻辑分析并给出了具体的实现方法。
The compressor set is a very important equipment in catalysis unit. With high rotational speed the rotational speed control system must have high dependability and precision. The program that uses ESD to control compressor rotational speed is introduced and detail logic analysis and realization method are presented.
