Monitoring of fans and blowers

The protection, monitoring and predictive diagnostics of fans and blowers for industrial applications is recommended for the most critical equipment in the plant.

Failure modes

Industrial fans are rotating machines where vibration analysis provides valuable diagnostic information. The most common types of faults diagnosed in industrial fans are:

• Imbalance
• Coupling misalignment
• Bank failures, resonance
• Bearing failures
• Pulley and belt problems
• Drive related failures

Monitoring systems

The recommended monitoring systems for this type of machine are:
Offline vibration:
Monitoring of failure mode parameters by periodic vibration paths with portable equipment.
Online vibration:
Continuous vibration and bearing condition monitoring with options for:

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