Case Studies

Case studies are important as they are the only way to compare the theoretical diagnostics to the actual physical condition of the component. Case studies provide evidence that the advice given is accurate and installs confidence and trust in the service being provided.

Case Study : Lost Production Prevented

A 600kW electric motor was being monitored by Howler’s online vibration monitoring system when rapid deterioration of the drive end bearing started to occur. The quick and accurate diagnosis by the Howler analyst allowed the client to plan a suitable time for both sourcing a replacement motor and production availability, all while averting a breakdown situation.

Case Study : Breakdown Prevented

When rapid deterioration started to occur to a client’s conveyor tail pulley bearing, the Howler online analyst recommended the bearing be replaced as soon as possible. It was found that the bearing housing had a cracked foot. Failure and production downtime would have been imminent if not for Howler’s online monitoring system.

Case Study : Collapsed Bearing

When collecting vibration data from a tail pulley bearing, it was noticed that the vibration levels had reduced significantly from the previous survey. However, the bearing was very hot. This raised alarm bells for the Howler reliability consultant and an immediate inspection revealed a collapsed bearing. 

Case Study : Damage Averted

Using thermography, a Howler reliability consultant detected a worn liner in a client’s SAG Mill discharge hopper. The liner was replaced at the next scheduled shutdown preventing damage to the hopper. 

Case Study : Failure Prevented

A routine vibration survey of a client’s jaw crusher motor revealed a significant increase in impacting within the motor drive end bearing. The root cause was a rapid deterioration of an outer race bearing defect. The motor was replaced at the next shutdown and the following survey shows levels were back to normal. 

Case Study : Quick Action

When vibration data was being collected from a snub pulley bearing at a customer’s site, significant vibration could be felt throughout the entire walkway and structure.

The data showed significant impacting related to rollers skidding and a broken cage. This would have certainly resulted in a seized bearing and lost production if the defect was not identified by the Howler reliability consultant and quickly acted upon by the client.
