Monitoring of Fans and Blowers

Protection, monitoring, and predictive diagnostics for industrial fans and blowers are recommended for the plant’s most critical equipment.

Failure Modes

Industrial fans are rotating machines in which vibration analysis provides valuable information for their diagnosis. The most common types of failures diagnosed in industrial fans are:

• Imbalance
• Coupling Misalignment
• Bench failures, resonance
• Bearing Failures
• Problems with pulleys and belts
• Errors related to propulsion

Monitoring Systems

The recommended monitoring systems for this type of machine are:
Offline vibration monitoring:
Monitoring of failure mode parameters through periodic vibration inspections using portable equipment.
Online vibration:
Continuous monitoring of vibration and bearing condition, with the following options:

• Integration of fault mode monitoring data into the Distributed Control System (DCS, SCADA, PI…)
• Automatic activation when vibration levels reach levels that are dangerous for the machine.
• Alerts regarding maintenance needs, e.g., balancing, relubrication, bearing replacement…
• Automatic measurement of diagnostic graphs.
• Remote access to data for external diagnostic services.
