The IIot Motor Diagnostic System – Unbalance and Misalignment
Faults going undetected in an industrial plant can have serious negative implications on production and often safety. It is of the utmost importance for the Maintenance Department to always be alert and aware of any technical issues no matter how big or small, that can result in unplanned downtime.
The IIot Motor Diagnostic System installed at a major international manufacturer in the automotive industry did just this. The IIot Motor Diagnostic System unit first gave a warning of a problem on 16 October 2015 and diagnosed a looseness problem. Due to pressure to meet production targets a decision was made by the maintenance team to wait for further indications.
On 19 November 2015, a new alert reflected, which initiated an inspection, resulting in the discovery of a loose attachment bolt on a Cooling Tower Fan, responsible for cooling the water circulated in the tower.
Next follows the sequence of alerts by the IIot Motor Diagnostic System unit at the time, as an example of the operation of the unit.
The system indicates looseness, and then the problem disappeared. Numerous alarms flagged in the software that related to foundation issues, including unbalance as well as misalignment alerts.
Continuous monitoring of foundation problem followed.
The IIot Motor Diagnostic unit continuously reported a unbalance, and misalignment problem.
Scheduled maintenance took place in February 2016, where the foundation problem was corrected.
RESULT: The IIot Motor Diagnostic System unit detected an Unbalance and Misalignment concern well in advance. Due to the early warnings provided by the IIot Motor Diagnostic unit an informed decision was made by the maintenance team to run and monitor the fans for any drastic changes that could affect production until the problem could be resolved during scheduled downtime.
Making the correct maintenance decisions can be an easy task if you have access to accurate information to base your decision making on.
Can you afford unscheduled downtime?
