The Importance of Vibration Analysis

February 20, 2018

In today’s fast-paced competitive business world, manufacturers are seeking every competitive advantage they possibly can to increase their production and minimize costs while maintaining product quality. The identification of defects within a machine, reducing equipment failures and unscheduled downtime is increasingly demanded of condition monitoring technologies. Vibration analysis has proven to be one of the […]

Could’a – Would’a – Should’a in Facility Maintenance Industry

February 13, 2018

How many facilities only collect vibration data when it doesn’t interfere with other activities? So often collecting and analyzing data is only one part of a given person’s responsibilities and workloads dictate that the collection and/or analysis take a back seat. When this happens, machine problems are not detected and therefore not reported for corrective […]

My Spectrum Does Not Indicate Misalignment so my Machine is Aligned, Right?

January 30, 2018

Condition Monitoring Expert Tip #9 by Mobius Institute No, sadly, that may not be correct. If the spectrum (and phase readings) indicate misalignment, then the machine will be misaligned. But if there is no indication of misalignment, the machine may still be misaligned. I know that may not make sense, but unfortunately it is true. […]

Why Do I Need to Use Time Waveform Analysis?

January 16, 2018

Condition Monitoring Expert Tip #7 by Mobius Institute Spectrum analysis provides a great deal of information about the health of rotating machinery. But you should consider the spectrum as a summary of the vibration within the machine. The Fast Fourier Transform takes the time waveform and computes how much of each frequency is present and […]

Why Do I Need to Use Phase Analysis?

December 19, 2017

Condition Monitoring Expert Tip #6 by Mobius Institute The vibration spectrum can provide clear indication of certain fault conditions, but when you see a large peak at the running speed (1X) what will your diagnosis be? What if you also see peaks at 2X and 3X? Now, if you are monitoring a large fan with […]
