PLANT MANAGEMENT
Abhishek Jadhav lists five things conditioning monitoring can reveal about your equipment
much more than simply sending alerts to warn of imminent failure, however. Properly executed, continuous condition monitoring can be used to support predictive maintenance, improve maintenance procedures, diagnose the root causes of problems and increase overall asset reliability in the long term. Traditional equipment monitoring
MONITORING C
ontinuous condition monitoring systems, typically remotely accessible, provide continuous updates on asset health. Te technology accomplishes
approaches such as manual route-based readings can warn maintenance and operations management of existing defects. Te problem is that manual readings only provide an instantaneous snapshot of asset health. Te defect could worsen immediately after the reading or a new issue could emerge, neither one of which would be detected before the next reading or the asset undergoes catastrophic failure, whichever happens first. Continuous condition monitoring systems provide the solution for these problems. Key condition-monitoring modalities include vibration analysis, temperature analysis and current monitoring. When properly analysed, this data can provide surprisingly granular insights about the asset, enabling the team to make strategic decisions about operations and repairs.

CATCH BEARING DEFECTS IN ADVANCE
Bearing defects are among the most common causes of failure in rotating assets. Root causes include lack of or improper lubrication, electrical damage, improper installation and brinelling. Vibration data, in particular, can provide detailed information about bearing issues, making it easy to distinguish between bearing-cage defects, lubricant breakdown and cracks in the races. [For rotating assets, catch common defects such as misalignment,
imbalance, looseness and bearing defects by continually monitoring vibration data.]
RUN TROUBLED ASSETS WITH CONFIDENCE Unscheduled downtime, whether invoked in response to an early fault or a catastrophic failure, can have similar effects on productivity. Tis is where continuous condition monitoring can really make a difference. Te monitoring system can be configured to take readings on the troubled asset 24/7, sending email alerts any time
Vibration spectrum shows a 1x peak (red dot at left), with a high 2x and 3x harmonics of the running speed. The appearance of additional harmonics indicates a looseness in the bearing
