就单级离心泵来说平常点检中除了经验判断如何用便携式测振仪判断设备问题?(主要是振动大的原因,如不平衡、不对中、轴承损坏等)

正常点巡检的问题大都是密封漏水、轴承损坏,软连接漏水。其它的好像没啥问题。地脚螺栓松动的可能也会有的。

水平振动大(轴向和垂直较小)很可能是转子不平衡,轴向增大查对中,加速度高频模式振动很大查轴承

设备振动根据不同的设备电机功率,存在不同的振动允许范围,这个在网上可以查到,这样你就可以初步判断振动是否在合理范围内。就轴承振动的问题,出了轴承游隙变大之外,还有一种隐蔽的可能就是轴承座和轴承的配合间隙变大。这个需要注意。

你说的是轴承跑外圈吧。:P

主要是用测振仪中的速度测轴承水平和垂直方向,振动有个标准范围!其他的机封是否泄漏,油位是否正常是靠巡检观察!
