协调调速系统在工作面刮板输送机中的应用

Application of Coordinated Speed Control System in Working Face Scraper Conveyor

针对晋北煤矿405工作面回采时发现采煤机与刮板输送机存在速度调节滞后、能耗高以及设备联锁控制效果差等问题,通过技术研究决定对刮板输送机与采煤机之间安装一套以变频器为控制器的协调调速系统。实际应用效果表明,该系统投入使用后大大提高了设备开机率,增加单班原煤量达650t,取得了显著应用成效。

For the Jinbei Coal Mine 405 face back mining found that the coal mining machine and scraper conveyor speed regulation lag,high energy consumption,as well as equipment interlocking control effect is poor and other technical difficulties,through technical research decided to install a set of scraper conveyor and the coal mining machine between the coordinated speed control system to the inverter as the controller,the actual application results show that the system is put into operation by greatly improving the equipment start-up rate.The amount of raw coal reaches 650 t,which has achieved remarkable results.
