Vibration Analysis PdM Services
Vibration Analysis is used for diagnosing mechanical faults in rotating machines.
Taking the time to insure proper set-up will eliminate confusion and errors downstream in the vibration data collection and analysis process.
ATS standard start-up procedures include: review of machine safety and accessibility for data collection, machine database set-up, digital pictures and report template set-up, route determination, data collection intervals, and applicable machine research. This start-up does not include the first collection of vibration data or vibration analysis report.
*One individual from your facility will accompany an ATS technician to review the supplied equipment list.
VIBRATION DATA COLLECTION
Consistent and accurate vibration data collection is the foundation of a successful vibration data collection program. Minimizing variances in collection is critical for accurate data analysis to occur.
ATS vibration data is collected completely from each machine comprising of driving components and driven components. A complete set of data from ATS consists of 3 measurement directions from each bearing location (2 in radial and 1 in axial direction). Based on bearing specific measurements and machine design, multiple measurements are incorporated including but not limited to: Acceleration & Velocity. Data is downloaded and briefly reviewed to ensure data integrity and imminent failures.
VIBRATION DATA ANALYSIS
Accurate vibration data analysis will provide a measure of asset health. This in turn will lead to increased reliability through early detection of machine faults. Trending of the vibration amplitudes allows for the development of a rate of progression, which facilitates the convenient scheduling of repairs prior to failure. Overall maintenance costs and energy consumption are reduced as a result. Vibration analysis will often eliminate reoccurring problems by detecting the conditions that lead to premature failure, such as misalignment or looseness.
Appropriate vibration measurement specifications are paramount in the ATS data analysis process, which are based on expertise in data acquisition and machine design. ATS vibration analysis utilizes all data collection points without the assistance of alarm levels. The final assessment is based on multiple measurements per direction and at each collected location. Severity of the final recommendation will be based not only on the vibration signature, but also on the rate of change observed with respect to historical trending.
Each machine is allotted an entire page consisting of supporting plots, digital image, abbreviated explanation of the analysis, severity assessment and recommended corrective action. Enclosed with each report is a summary which ranks each piece of equipment based on the assessed severity.
