Maintenance stop scheduled after indication of early failure The PROGNOST®-Predictor system showed increasing Confidence Factor values on the HFE spectrum for the Bearing Bottom Torsion Shaft on August 07th in 2016 first. Within the following months the confidence still kept on a high level till the beginning of November, when the amplitude showed the first higher peaks. On November 05th, the amplitudes violated all thresholds and the acceleration grew from 0.1 m/sec² to 2 m/sec². After the final maintenance work at the end of November the amplitude and Confidence Factor values returned to good condtion. Finally, you see on the last analysis picture the early recognition of HFE 10-20 kHz in relation to the HFE 5-10 kHz and the acceleration [...]

If best scenario had played out there would have been additional cost savings of $ 2.8 Million This case study illustrates how PROGNOST®-Predictor detected impacting in the time waveform of the gear pump along with a ticking sound coming from the gearbox. Sequence of Events 3/22/2018 at 9:30:00 am: PROGNOST Systems received message from customer who was concerned that they heard a ticking coming from Gear Pump gearbox. Customer was asked to look at the time waveform on one of the sensors near the ticking and we found a very strong impacting happening that was very concerning. 9:38:00 am – Customer sent a screenshot of time waveform which showed a large amount of impacting that he had found. This impacting [...]

Detected misalignment in the input shaft bearing – Successful shutdown of MAAG gearbox

PROGNOST®-Predictor successfully detected misalignment in the input shaft bearing that progresses to imbalance within 15 minutes, allowing the extruder line to be successfully shutdown before additional damage occurred. The MAAG gearbox in service since 2013. Pic 1: Gearbox showing oil residue on the side of the housing   Pic 2: PROGNOST®-Predictor trend before event   Pic 3: Trend just before shutdown   Immediate actions taken Operations brought extruder to a safe state Proper people were called to review all information and data to assist with a path forward Vibration group checked the input shaft It was determined that input shaft axial movement was out of tolerance Machine was kept down until spare gearbox and motor could be installed Root Cause Pic 4: Input [...]
