Vibration Analysis

Comments Off on Vibration Analysis

By the time a mechanical problem becomes noticeable by normal human senses, it may have already become an expensive repair. Vibration analysis uses technology and equipment created specifically for plant-based mechanical defect detection. It can preemptively identify specific faults in rotating equipment, identifying the root cause of the problem and allowing you to do relevant maintenance on your schedule.

At Advantage Reliability Services, Inc., we understand the complexities of vibration analysis on various types of equipment.  Frequency ranges of defects depend on several variables such as rotation speed, bearing number and diameter, inner and outer race circumference; these cannot be accurately analyzed with a one-size-fits all approach.  Our predictive maintenance technology, combined with our knowledge and experience, take into account your specific requirements and helps determine your best course of action.

Outer race defectThis electrical fluting induced outer race defect of a bearing from a 600 HP motor (pictured to the left) was changed during a scheduled maintenance outage and was detected and the severity determined using PeakVue technology.

Instead of using demodulation techniques which subtract carrier frequencies and use low pass filters, PeakVue technology preserves the peak amplitude of stress waves emitted from a bearing or gear defect or abrasive wear.

The additional vibration data provided by this technology allows for earlier and more accurate defect prediction and analysis that routine vibration data collection techniques may overlook.
