锅炉一次风机电机轴炉振动大
Reply #42018-12-06
锅炉一次风机运转一年后开始出现振动大,轴承温度高。更换轴承后用了半个月又出现振动大,后来换了个大厂家进行维修,用一两个月后又出现振动大。后来换个新电机调试完运行了几天振动又开始上升。主要是轴向振动大。风机的振动还算平稳。请问是什么原因?有什么好的解决办法吗?

这类问题通常上上个片子,整体的包括设备基础础的二次灌浆部分。导致这个问题的大都是原始安装遗留下的问题,就是二次灌浆的质量有问题。另外,后天出现的这类问题有转子的动平衡,安装的水平度、地脚螺栓的紧固、及工艺上的吸的压力排气压力及相对应的温度等。最好对着这些做一次彻底检查。二次灌浆部分要做重点检查,是否采用灌浆料,是否用普通砂浆堆放不捣固,用钎子找个地方戳一下看看强度如何。要是强度不好就得从新的二次灌浆。

五. 往往这类设备底座为焊接的,刚性差,容易变形出现应力,天长日久地脚松了,也有可能!再就是混凝土关注整个底座内部,看看有无好转!
