Vibration analysis can often pinpoint a failing element of a rotating machine in time to avoid catastrophic failure and costly replacement of machinery as well as lengthy production …

Frequency is the number of times an event occurs in a given time period (the event being one vibration cycle). The frequency at which the vibration occurs indicates the type of fault. That is, …

m natural frequency causing high vibration. High BPF can be generated if impeller wear ring soizes on shaft or it welds fastening diffuser vanes fail. Also, high BPF can be caused by …

Hopefully at this juncture the effectiveness of the Vibration Analysis Periodic Table as a screening tool is becoming obvious. To this point we have used the frequency and directional response …

The signal is subject to analysis but whereas vibration analysis monitors signals at low frequencies, which have to be ‘treated’ to eliminate background noise, AE uses higher …

This chart applies to the overall rms vibration velocity level with specific limitations: For machines running at speeds above 600 RPM a low frequency cut-off = 10 Hz applies and a maximum …
