浅析云冈矿电机滑环碳刷组件改造

Analysis on Transformation of Electrical Slip Ring Carbon Brush Components in Yungang Mine

针对云冈煤矿主井北部电机滑环碳刷组件改造前存在事故及改造后效果和效益情况的比较,得出新型碳刷的有效接触面积和弹簧压力大为增高,产生的噪音量也大大降低,有效的解决了滑环打火甚至爆炸的安全隐患,保证了设备安全运转,减少了事故率,减少了因维修浪费的时间、人工,大大提高了提煤量。

Through the existing accidents of electrical slip ring carbon brush components in the main shaft of northern Yungang coal mine before modification and the comparison of effect and benefit after transformation, it is concluded that the effective contact area of the new type carbon brush and the spring pressure are increased, while the amount of noise is greatly reduced, thus effectively solve the potential risk of slip ring striking fire or even exploding, ensure the safety operation of equipments, decrease the accident rate, reduce the amount of time and manual work, and greatly improve the coal production.
