Vibration Analysis is a key condition monitoring technique given its versatility detecting a wide range of failure modes.
Within ALS’s condition monitoring services, we offer a cost-effective vibration analysis and monitoring service which closely aligns with the principles of ISO 13373. Vibration analysis can be performed on both rotating and static equipment, and used to monitor for three key considerations:
- Surprise-free asset performance - detecting vibration anomalies, providing diagnosis and prognosis;
- Cost effective maintenance planning evaluation of the overall health condition of the asset, which allows sufficient time for remedial action; and,
- Reduced production cost - maintaining the assets at their optimum level.
Utilising industry leading equipment, ALS technicians are certified to ISO 18436 standards and are extensively experienced with equipment reliability, failure modes and symptoms of failure. Our technicians gather vibration data directly from machines and analyse this information both on-site, for rapid interpretation turnaround, and at our ALS facilities.
Through their extensive experience, ALS technicians and engineers can accurately interpret the vibration data, make informed assessments of the condition of an asset and offer practical recommendations for remedial action.
Defects detected through vibration analysis include, but are not limited to:
- Rotating equipment bearing defects including cracking, spalling, race and cage defects.
- Gearing defects including cracking, broken tooth, gear misalignment, gear wear and spalling.
- Lubrication problems.
- Misalignment of assembled rotating equipment, including gear and shaft misalignment.
- Unbalanced components including impellers, gears, couplings and shafts.
- Motor defects.
Abnormalities detected through structures, pipes or vessels experiencing vibration include:
- Presence and effect of excessive vibration in structures and piping.
- If excessive vibration is occurring, an engineering assessment of how such vibration may lead to structural fatigue and damage.
Rotating equipment including, but not limited to:
- Reciprocating engines
- Vibrating screens
Static structures experiencing all forms of vibration, including:
- Environmental background vibration
- Process induced vibrations
- Transmitted vibration from rotating and reciprocating equipment
Vibration analysis plays a key function in monitoring and diagnosing faults in rotating and static machinery. Through vibration analysis, the loss of equipment due to critical failure is replaced with focused maintenance, and the cost of replacing entire assets is decreased to repair work. Overall, the analysis brings increased safety, revenue and employee efficiency.
