1事故现象我公司一台Φ3.2m×13m球磨机所配套的MBY1000减速器突发故障,事发时中控操作员从视频监控中发现该减速器的上部排气孔中有大量黑烟冒出,当即果断停机。查看当时中控微机所显示减速器油站数据没有报警信息。油温、油压及高压电动机电流等均正常。经过机修工初步检查发现该减速器靠近副传侧轴承温升很高,后经拆机细查发现一侧轴承已经严重烧毁。
An accident phenomenon My company a Φ3.2m × 13m ball mill supporting the MBY1000 reducer sudden failure, the incident when the operator from the video surveillance control found that the reducer in the upper exhaust holes in a large number of smoke pops up , Immediately decisively shut down. Check the central control computer at the time showed that there is no alarm information on the gear unit data. Oil temperature, oil pressure and high-voltage motor current are normal. After a preliminary inspection mechanic found that the reducer near the Vice side bearing temperature rise is high, after the disassemble scrutinized side bearing has been severely burned.
