变频器固定频率控制在超长链条输送线中的应用

XX公司为了降低从车间1到车间2输送物料的运输成本,在车间1和车间2之间建设了一条总长650米的链条输送线,用于物料的连续输送。由于原控制系统存在诸多缺陷,并缺乏及时的售后服务,特组织公司内外技术力量对该输送系统进行了技术研究,制定了"变频器多段固定频率控制"方案。本文主要介绍了该输送系统的功能、系统改造方案的具体设计及改造后系统的运行调试,实践证明该方案大大降低了故障率,提高了系统的稳定性。

Application of Fixed-frequency Control of Inverter in the Long Chain of Transmission Lines

To reduce the transportation costs of materials from workshop 1 to workshop 2,a company constructs a 650 meters chain conveyor line from workshop 1 to workshop 2 for the continuous delivery of materials.Since the original control system has many defects,and lacks of timely service,the company especially organizes inside and outside technical force to study the transport system,and formulates program of fixed-frequency inverter control.The article mainly presents its function,reform design and debugging.The ...
