Sensemore Case Study - Centrifugal Fan

Implementation on Critical Centrifugal Fan Motor

A condition monitoring system has been integrated on the centrifugal fan motor, which is one of the most critical pieces of tobacco drying equipment in a facility that performs tobacco manufacturing. The fan must operate continuously in order to perform drying operations. A failure and downtime in the fan will cause disruption of the entire production line. The fan is driven by an induction motor and the movement is transmitted by a coupling.

What's inside

12 pages · 4 sections · PDF

  • Sensemore Infinity sensors on the drive-end and non-drive-end bearings of the motor driving a tobacco drying fan.
  • A potential bearing failure was predicted while broadband vibration was still within the acceptable zones of ISO 10816-3 and no standing alarm existed: high-frequency bearing faults do not show in a broadband trend.
  • The motor was replaced with a spare; on the new motor the system immediately flagged misalignment, the coupling was realigned and vibration levels dropped.
  • Unplanned downtime was prevented and equipment lifetime increased by up to 9%, on a machine fresh from maintenance, which is the bathtub curve in practice.
