“It’s not only assets such as motors, pumps, and fans that Motion Amplification can be used on. It’s great for larger structures and machines too. By filtering the MA videos to different frequencies, we can gain a much deeper understanding of the machine’s motion.
Nice example here of a paper machine suffering from raised vibration levels on the wet end section, with levels up to 8 mm/sec on some rolls. Testing with our Emerson AMS 2140 Analyser and IRIS M Motion Amplification Camera determined a resonance issue at higher machine speeds, excited by the wire rolls (1XRPM). Over the years, increased machine speed for production had taken it further into the resonance range.
One common result of running in these resonant ranges is the loosening of holding down bolts, amplifying the problem further. In this case, we recommended checking all base bolts for tightness after reviewing the MA footage, which showed a rocking motion of the machine. Although not a long-term fix, the levels reduced to 3mm/sec RMS, which the site was happy to run with. A new maintenance inspection has also been added to check base bolt tightness routinely.” — Stuart Walker
