刮板输送机是采煤设备中不可分割的一部分,它能否正常运转,将直接影响工作面的正常生产。1常见故障及原因分析1.1电动机(1)电动机启动不起来或启动之后又缓慢停下来负荷太大;运行部件有严重卡阻;采煤工作面不直,凸凹严重;供电电压太低;变压器容量不足,启动压降太大;开关工作不正常;机头、机尾电动机间的延时太长,造成单机拖动;电动机本身的故障。(2)电动机发热电动机风扇吸入口和散热片不清洁,散热状况不好;超负荷运转时间太长;轴承缺
Scraper conveyor is an integral part of coal mining equipment, it can operate normally, will directly affect the normal production of face. 1 common faults and causes analysis 1.1 motor (1) the motor does not start up or stop slowly after starting to load too much; running parts have serious jamming; coal mining face is not straight, convex serious; supply voltage is too low; transformer capacity Insufficient to start the pressure drop is too large; switch work is not normal; nose, tail between the motor delay is too long, resulting in single drag; motor itself fault. (2) motor heating motor fan suction inlet and heat sink is not clean, heat dissipation is not good; overload operation time is too long; lack of bearings
