皮带运输机是当代最为得力的输送设备之一,在整个输送机范畴中,它是应用最为广泛的一种设备,它的产生已有上百年的历史了,现以成为冶金、矿山、水泥、码头、化工、粮食等行业最主要的运输工具。早期皮带运输机由于其功率小、运距短、速度低,应用受到一定限制。现针对皮带运输机控制系统中存在的问题,把可编程序控制器和变频器应用于皮带运输机控制系统上,利用可编程控制器取代继电器进行控制皮带运输机的起动和停止。提高了系统的可靠性,系统的调速控制采用变频器进行变频调速,使调速性能更加稳定,提高了系统的稳定性
Belt conveyor is one of the most powerful transportation equipment in the contemporary era. It is the most widely used equipment in the entire conveyor area. It has been produced for hundreds of years. Now it has become a world leader in metallurgy, mining, cement and wharf , Chemical industry, food and other industries the most important means of transport. Early belt conveyor because of its small power, short distance, low speed, the application subject to certain restrictions. Now for the belt conveyor control system problems, the programmable logic controller and inverter used in belt conveyor control system, the use of programmable logic controllers instead of relays to control belt conveyor start and stop. Improve the reliability of the system, the system of speed control using frequency converter for speed control, speed control performance more stable and improve the stability of the system
