导电滑环磨损快的原因
2022-07-05 07:50:00 【xiaohouzi007】
根据滑环的工作方式,我们可以知道滑环属于滑动接触,滑环在滑动过程中与其他物体的接触面是最先磨损的。滑环的磨损速度对其使用寿命起着决定性的作用。经过大量试验,得出滑环磨损程度越低,使用寿命越长的结论。从大量数据中我们可以知道,不同原材料生产的滑环耐磨性是不同的。制造滑环的原材料的强度、摩擦系数和电流密度对滑环运行时的磨损有很大影响。
当滑环与其他物体接触时,压力越大,就会产生相同的摩擦力,导致滑环磨损很大。但滑环上的接触压力太小,滑环接触接触面时阻力会瞬间增大,严重时会出现火花,也会造成滑环磨损,因此,滑环的磨损速度由制造材料的性质决定。滑环的生产材料和生产工艺通过标准才能生产滑环,可以减少工作时磨损的影响。
默孚龙科技滑环磨损如何修复:
1、表面烤油:用乙炔火焰在磨损的轴颈表面烤油;
2、修复键槽:支撑键槽内的焊点,现场修复,尽量用平键安装;
3、表面处理:用砂轮机打磨磨损部位,用样品冲圆周环,使点蚀点均匀凸起;
4、清洗:用无水乙醇清洗抛光后的轴承室;
5、共混SD7101H材料后,采用Sore工业现场修复工艺修复;
6、将滑环定子组装到位,并在现场锁紧螺母。
