subject: Significance Of Vibration Testing And Analysis [print this page] Vibration is a mechanical phenomenon whereby oscillations occur about an equilibrium point. In the world of motorized maintenance, vibration remains one of the earliest indicators of a machine's health. It is an undistinguished characteristic of practically all industrial machines.
When vibration accelerates beyond permissible levels, there are two possibilities
a)It may signify only a temporary normal disturbance or
b)It may be a bottleneck and indicate the need for further evaluation of the causal reasons, or for immediate safeguarding action
Every company thus is in need of a simplified solution that helps them
"Instantly and dependably comprehend machine health and severity of condition, if any
"Increase competence by working against a prioritized problem list
"Take control of downtime costs by forecasting problems proactively and identifying causes of chronic failures
"Bridge the gaps pertinent in the skill set of the maintenance team
Understanding why vibration occurs and how it makes itself evident is the primary step towards preventing vibration from creating hiccups in the production workflow. Vibration testing and analysis is thus one of the very popular techniques employed to detect and analyze the early signs of machine malfunction and failure, allowing them to be fixed or substituted before a costly failure occurs.
Vibration analysis provides the following timely, accurate and necessary information which can be immediately action upon, if needed.
1)Early detection of mechanical fatigue and breakdown
All rotary equipments vibrate to some extent, but as older parts begin to get closer to the end of their product life they begin to vibrate more radically, and in distinctive ways. Ongoing check on equipment allows these signs of wear and tear to be recognized and evaluated well before the actual disaster happens
2)Accurately monitor the health of plant machinery
Software and vibration analyzers are used for monitoring processes. They record vibrations using sensors like tachometers and accelerometers and help the plant maintenance expert distinguish between permissible and normal vibration, and the type of vibration that calls for immediate service attention or substituting of troubled equipment
3)Reduced downtime and increased savings
Being a proactive approach, vibration analysis can lead to huge savings in cost for the firm when compared to traditional methods of maintenance that are either preventive or reactive.
4)Prognosis of remaining service life
The analysis also helps a company know the functional and operative life of machinery and help it plan its finances accordingly, to fund the machinery"s replacement
With increased pressure on companies to engage in cost cutting measures, vibration testing and analysis is for sure a cost-conserving one.
