水平振动大的话首先考虑装配公差,锤子振动大的话考虑安装松紧

本帖最后由 3983596_FPPZ 于 2018-10-30 12:58 编辑 怎么都没有想到是联轴器不对中造成的呢?问题原因已发现,不对中0.3mm,故障已排除。装配人员杖三十

我们这边有一台层目前也是这个情况,振动达到了12mm/s,之前怀疑是设计余量给大了,最后经过切割叶轮,振动仍然达到了5.2mm/s,该查的都查过了,也不知道怎么回事。

我们校完中心也没用,情况还是一样。

最好的办法就是频谱分析法
Reply #102018-11-04
目前我们公司频谱用的不是很多,相关的技术也比较欠缺,不可否认频谱分析确实不错。
Reply #112018-11-04
泵要是质量失控,频谱之后 查找原因也很麻烦
Reply #122018-11-04
有可能是叶轮跑了,做个动平衡找找。

电机振动大不呢,电机单试没 进出口管线振动不
Reply #142018-11-05
电机振动倒是不大,当泵振动比较大的时候,也能感觉到出口管线的振动比较厉害。
