Water/Waste Processing Magazine • February 2011 A southeastern US water company has been developing a condition monitoring program with LUDECA as their partner, to monitor their on-surface equipment with VIBSCANNER® and VIBCODE® systems. The current program has provided significant benefits and cost savings by preventing expensive pump and motor failures, as well as optimizing their current [...]

I recently used an audible recording of a time domain waveform acquired with the VibXpert to help demonstrate the value of the actual “audible” sound of a bearing fault during a recent condition monitoring survey (baseline measurements) of a multistage circulation pump. As we know, the time domain waveform signal is truly the “raw” data [...]

WaterWorld Magazine • February 2011 A Florida water treatment plant recently discovered that having full-flex (double engagement) gear couplings at either end of a spacer shaft connecting a Lufkin gearbox to a 13,000 gpm Worthington water pump caused self-exacerbating vibration that eventually destroyed the gearbox twice within 3 months, requiring a full rebuild each time.After [...]

If, based upon your vibration data, you suspect that a motor has an electrical defect, then you can perform a quick verification check using your vibration data collector. Place your vibration data collector in a live mode or continuous measurement mode. Turn off the electric power to the motor. Any electrically induced vibration should cease [...]

MYTH: “Coupling alignment tolerances provided by the coupling manufacturer are good enough for shaft alignment.” Or “There’s no need to align your machines tighter than the tolerances allowed by your flexible coupling” TRUTH: This is wrong because a good quality flexible couplings may be built to withstand much more misalignment than what is good for [...]
