What is vibration monitoring?
Vibration monitoring is used to identify changes in the general vibration levels of rotating machinery including fans, pumps, turbines and motors to monitor condition and performance.
These vibrations can be categorised into different levels of intensity, frequency, and amplitude, and used to identify if the vibration is damaging to the machine and its components as well as creating harmful noise emissions. From this, the cause of vibration can be identified and necessary repair works can be carried out to remedy the fault and extend the lifetime of the machine.
What can vibration monitoring detect?
- Gear issues
- Electrical faults
What can vibration monitoring do for you?
- Improve the reliability
- Increase machine lifetime
- Predict future failures
- Minimise downtime
- Maximise productivity
What causes mechanical vibration?
If left undetected, imbalance can cause major damage and failure to rotating machinery. A centrifugal force is created when a ‘heavy spot’ in rotating equipment revolves around the machine’s axis. This imbalance becomes greater as the rotational speed increases therefore increasing machine vibration reducing bearing life and causing structural damage in severe cases.
Wear and looseness
As components such as roller bearings, drive belts or gears become worn, they can cause vibration. In addition to this, loose bearings can cause serious damage including wear and fatigue to bearings and bearing mounts as well as shaft and the surrounding structure.
Vibration is often the most effective indicator of alignment issues. Misalignment may be a result of incorrect assembly after maintenance, thermal expansion or the shifting of components.
Detecting the problem before it’s too late
Effective vibration analysis is essential to maximising machinery uptime, and regular monitoring can ensure this by detecting issues in good time before they potentially have catastrophic consequences. The reduction of vibration through proper dynamic balancing will help ensure the machine operates smoothly and reliably.
