摘要
针对大唐塔山矿所用刮板输送机存在启动、停机冲击大,无法长期在低速下工作,严重影响井下物料输送效率的现状,提出了利用变频控制器对刮板输送机的运行过程进行控制的方案。应用表明,采用变频控制技术能够通过对刮板输送机驱动电机工作电流的检测,实现对刮板输送机功率平衡的控制,提升刮板输送机工作时的稳定性。
The scraper conveyor used in Datang Tashan Mine can’t work at low speed for a long time because there is a great impact when it starts and stops, which seriously affects the efficiency of underground material transportation. Due to this, a scheme of using frequency conversion controller to control the operation process of the scraper conveyor is proposed. The application shows that the frequency conversion control technology can control the power balance of the scraper conveyor and improve its stability by detecting the working current of the drive motor.
