Synchronous Control System of Transporting Tube Sheet Chain in Pipeline Anticorrosion Production Line

近年来,随着工业技术水平的不断发展,多台异步电动机共同驱动方式在轧钢、传动、纺织、动车牵引等领域得到了广泛的应用。因此,研究并改善多台异步电动机同步控制系统的性能以及提高同步控制精度对于满足各种制造设备以及产品质量需求具有十分重要的理论和现实意义。本文介绍了管道防腐生产线运管板链同步控制的一种方法,建立了以PLC为主站,变频器为从站,以两台异步电机的转速同步为研究对象的控制系统。对其在实际应用中出现的问题进行了分析,提出改进措施。

In recent years,with the development of industrial technology,multi-induction motor drive is widely used in steel rolling,transmission,textile,traction and other fields.Therefore,it is of great theoretical and practical significance to study and improve the performance of multi-asynchronous motor synchronous control system and to improve the precision of synchronous control.This paper introduces a method of synchronous control of transport tube plate chain in pipeline anticorrosion production line,and sets up a control system which takes PLC as the main station,frequency converter as the subordinate station,and two motors’rotational speed synchronization as the research object.The problems in practical application are analyzed,and the improvement measures are put forward.
