一、前言
风机设备铭牌参数如:
电机型号M2QA112M4A、功率4KW、额定转速1435r/min(变频器调速)、前轴承型号skf6207、后轴承型号skf6206、轴承箱前后轴承6312。
2016年2月18在给排风机2#做振动检测时发现皮带轮侧频谱有异常变化,在皮带轮侧水平向速度谱出现较大转频及谐频,对比上次检测2016年1月14日明显增多增大,可以确定有旋转松动现象,结合现场给出的故障报告为轴承跑套。
二、故障分析
风机F3水平向振动趋势检测趋势,趋势持续上升,振动数值如下:
图3、4是风机F3测点水平向速度与加速度频谱,速度频谱中出现转频及2-16倍的谐频,这些谐频是机械响应中的脉冲和截断的结果。加速度频谱同样出现转频及谐频,说明F3测点有松动现象(旋转松动),这种情况轴与轴承过盈不足有关,轴承可能存在跑圈导致轴承档磨损。
三、结论
1.轴承有跑圈现象,轴承档可能磨损。
