1"热油泵温度271,运行运行驱动端径向震动超标6.8 水平3.2 非驱动端径向3.8 水平2.8 轴承都是新换的,转速155,会是什么原因造成的径向震动大?而且只有驱动端大,找正数据都检查了没问题,马架螺丝全部检查了没问题,求大神帮忙

除安装问题,是否还有流量问题。

我曾经碰到过双支撑泵驱动端机械密封损坏太快,非驱动端机封完好,轴串动太大,后来分析可能是喉部衬套磨损过大,平衡孔有堵塞等原因。

5"热油泵我们这里是磁力泵,不涉及找正问题,但电机在高温环境下,需要及时补油

你好,一般的径向振动大,从经验来看,有这样几种情况:设备底座或构架强度不够、较弱;地脚螺栓松动或是设备基础不实、出现裂纹等等情况,

地脚紧固不牢或者对中不好

问问厂家出厂时清水试验振动值多少,跟现在比较一下

99驱动端振动大且你安装间隙全部符合,检查电机侧和联轴器,还有电机是否为原配的电机。

10油泵的温度较高,建议热态找正看看有没有什么问题。

1"泵是否汽蚀了,把容器内液面升高一些看看。

1"建议查一下管道是否有应力,转子动平衡,包括联轴器的动平衡,电机是否有软脚,热态联轴器对中
