瓦楞机轴承磨损快积碳多,是换轴承?还是换润滑脂?

XX纸箱包装厂,瓦楞机纸箱生产线,存在严重的润滑脂问题,多次解决无果。到厂实际勘察时发现瓦楞机轴承侧面,满地都是黑色的油脂污渍,询问后得知由于润滑脂流失很快,工厂设备维护人员不得不每运行两天,就必须停机加脂一次,有的短期内就大拆进行清洗,然后重新加脂,一个流程下来,光是拆装的就长达1天,如果轴承坏了而且没有备用轴承的话,那就不是一两天能够解决的,即便是这样在生产中设备运行仍然会出现各种故障和意外。尤其是进口设备,更换一个轴承多则需要3-5千元,除生产受到影响外,成本必然增加了不少。

故障分析:

瓦楞辊是纸箱生产中最核心的部位,除了其本身对金属材质的硬度、耐磨性都有着非常高的要求外,配套部件瓦楞机轴承的维护和保养也尤为重要。由于工艺需要,瓦楞辊经常采用电加热或过饱和蒸汽加热的方式,温度一般为180℃~230℃之间,瞬时温度可达250℃。很多润滑脂由于高温性能不良、粘附性不够、抗氧化性能不好,出现滴、流、发干、积碳,有的出现轴承干磨,还有的甚至抱死轴承、严重积碳。

存在问题:

①长时间运行后,轴承温度升高,选择的油脂不合适会出现、滴、冒、跑、漏现象。

②积碳、抱死轴承。

负面影响:质量事故增加、停产风险加大、维修成本很高。

解决方案:

根据现场工况勘查和询问分析,最终推荐使用瓦楞机专用轴承润滑脂,采用全氟聚醚合成油,并加入抗氧、防锈等多种高效添加剂,极佳的高温稳定性、低挥发性、低温流动泵送性;优良的氧化安定性和抗水淋性,适宜潮湿环境下的轴承润滑;优良的材料相容性,绝缘性好,耐水、耐油、耐真空、耐粉尘、耐绝大多数有机溶剂及强酸碱;优良的润滑性和极压性,抗磨损、抗擦伤、抗燃烧、抗辐射、抗腐蚀,保证轴承极长的使用寿命;完全符合工厂瓦楞机要求。

工厂回馈:

瓦楞机专用轴承润滑脂切实解决了工厂瓦楞机存在的润滑问题,大大降低了维护成本,延长了机器寿命,提高了生产效率。
