Friction sound, impact sound, soft sound, harsh sound, continuous sound, intermittent sound.
The owner needs to focus on the sound of the bearing during inspection. Generally, if there is metal friction or impact sound, accompanied by vibration, you need to pay attention. More practice is needed on site. However, large units still need to rely on various parameter curves for analysis. Many units also have portable spectrum vibration measuring instruments for general machines and pumps. It is more intuitive and accurate to judge the operating status of bearings through spectrum curves.
Vibration, impact, friction, and at the same time, there are phenomena such as high bearing temperature and no pressure at the outlet.
