大家好,一台屏蔽泵加装变频器后轴监器指针红区,想请教下变频器对轴监器怎么形成的干扰,谢谢!

估计是速度下降过多后,油膜减薄,转子明显下降,据此轴监器检测到下降数据偏离设置数据,指针偏转指到红线区。而红线区按出厂要求就是轴承磨损了。

有部分原因,但是额定转速运转时也是红区

那实际情况是否泵已经进入磨损状态了?变频切掉后呢?
Reply #52019-12-15
轴承磨损跑偏后产生的感生电流变小使得轴承检测表指针在红区。

请问哪个厂的。不同厂出的轴监器不同,同一厂出的轴监器也有几种(机械的、电子的等等)

大连帝国,大连环友等帝国系列的轴承监测器,是通过模块输出电压显示在监测器上(TRG表) ;模块如果是设计使用在工频下的,变频工况就一定会误指示,因此有两个办法修正:1.将电源去掉 2, 更改为可以在变频工况下使用的模块

红区时泵运行有何异常吗,振动?异响?发热?
Reply #92019-12-30
没有异常 只是监测表指针在红区。 问题是制造厂红区为危险区域,是不允许继续使用的,尤其巡检必须要排除的隐患---正常使用状态下轴承磨损到极限了显示为红区,因此必须尽快消除

没有异常,厂家答复需要更换适应变频器的轴监器模块

泵有没反转,泵反转,也会到红区
