Challenge:

A Midwest HDPE pipe manufacturer needed an end-to-end condition monitoring system to monitor the health of their machine assets, prevent persisting unplanned downtime and increase productivity.


The manufacturer selected a risk-free trial of Vero and in July 2020, Nikola Labs installed 57 monitoring points on 13 critical assets. Four days after installation, the dedicated Vero Condition Monitoring Engineer (CME) observed harmonics of 126 Hz with 30 Hz sidebands on the drive end of the facility’s primary Extruder Motor. The bearings on this motor had been replaced just five months prior and route-based monitoring had failed to find any issues in April.


Solution:

After analyzing the data, the Vero CME quickly issued a Prescriptive Asset Alert (PAA), recommending immediate replacement of the motor bearings at the next available opportunity and, until then, ensure bearings are greased without over greasing.
