电机轴承运转过程的检测

电机轴承的滚动声:采用测声器对运转中的电机轴承的滚动声的大小及音质进行检查,即使电机轴承有很轻微的划伤,也会发出异常音和不规则音,测音器就能很好的解决这个问题。如果润滑、安装部合适,则电机轴承温都会急骤上升,温度就会不正常的升高,这时必须停止运转,采取必要的防范措施。
轴承的振动:轴承振动对轴承的损伤还是反应比较明显的,比如这些常见的问题压痕、锈蚀、裂纹、剥落、磨损等在测试的时候能够明显的感觉到,所以,通过采用特殊的轴承振动测量器(频率分析器等)可测量出振动的大小,通过频率分不可推断出异常的具体情况。测得的数值因轴承的使用条件或传感器安装位置等而不同,因此需要事先对每台机器的测量值进行进行一定的操作来确定Z后的数据。
电机轴承的温度:电机轴承的温度,有的电机轴承温度是可以测量出来的,如果利用油孔能直接测量电机轴承外圈温度,则更位合适。通常,电机轴承的温度随着运转开始慢慢上升,几个小时后达到就比较稳定了。电机轴承的正常温度因机器的热容量,散热量,转速和转动的方式也会不一样。使用热感器可以随时监测电机轴承的工作温度,能够在事故发生前就有准备和提醒。
