VIBRATION ANALYSIS
Recording vibration readings, by vibration consultants, for rotating machinery is like monitoring the human heartbeat. And only highly skilled and experienced people can relate a person’s heart beat to their health. In the same way, in the world of machinery maintenance, only highly skilled and experienced vibration consultants can interpret the vibration signature of a machine and use that data to analyze its condition. All rotating equipment has a vibration signature. Understanding how that signature relates to machine condition and performance is critical to any worthwhile vibration analysis service and that’s why Engineering Dynamics’ skilled vibration analysis consultants lead the field. It takes condition monitoring one critical step beyond analysis to diagnosis and prognosis.
VIBRATION ANALYSIS SERVICES HELP YOU TO:
- Reduce downtime losses by identifying problems before they lead to catastrophic failure.
- Increase time between equipment overhauls.
- Monitor the success of corrective action.
- Quickly identify installation errors before costly damage can occur.
A COMPREHENSIVE SERVICE
For vibration analysis services, knowing what to look for and where to find it is only valuable when coupled with strict processes that guarantee quality and repeatability.
The process is managed by experienced vibration analysis consultants of the highest caliber and backed by an investment in the latest technology. This is why you will find that Engineering Dynamics Vibration Analysis Services can become a valuable addition to your operation. Reporting for this service includes at-a-glance exception reporting. Reports are color coded for quick and easy reference and provide a description of the fault, severity, trend, additional recommended testing, alternative actions and prognoses.
Diagnosis and prognosis incorporates site specific and machine specific information. For example, at machine level, we consider whether problems are developing at a rapid or gradual rate. At a site level, we consider factors such as the effect of recommended maintenance on production outputs, the availability of spares and whether successful corrective action is realistic. We also consider the effect that ‘no action’ might have on production outputs and maintenance budgets.
MUCH MORE THAN DETECTION OF MISALIGNMENT AND UNBALANCE
Misalignment – Investigate and correct problems associated with misalignment. Including hot alignment.
Unbalance – Investigate and correct unbalance where static, coupled or dynamic unbalance problems exist for individual parts and fully assembled units in situ.
Soft Foot – Misalignment is often blamed in cases where ‘soft foot’ is the true problem. We test for and eliminate soft foot problems.
Gear Mesh Abnormalities – Identification of which gear is problematic and why.
Journal Bearing Faults – Identification of wear and clearance problems, oil whirl and oil whip.
Belt Drive Faults – Identification of worn, loose or mismatched belts, eccentric pulleys and belt resonance.
Mechanical Looseness – Identification of base/frame problems, loose hold down bolts, loose bearings or loose rotors.
AC Induction Motor Faults – Identification of various faults including stator and rotor eccentricity and phasing problems.
Pump Faults – Blade/vane pass and cavitation.
Resonance – When machinery upgrades or structural modifications lead to structural resonance, we can identify which machine or machine element is problematic.
Beat Frequencies – When analysis is complicated by the superposition of two vibration signatures, we will isolate one machine to enable review of the other.
