Condition monitoring prevents machines from causing costly fires

By Published on April 29, 2022


Condition monitoring prevents many machine issues. Recently a North American refinery has been facing costly fires. The refinery identified the solvent booster pump as the cause of the fires. The monitoring schedule for the pump was once a week and was performed using a hand-held vibration instrument. Monitoring once a week seemed like enough given the typical 6-month lead-time from fault detection to failure. Yet, some faults only had a 6-hour lead time, making the current monitoring system impractical.

The refinery needed a protective monitoring solution that could detect and distinguish fast and slow faults so the refinery could shut the pumps down in time. Brüel & Kjær Vibro recommended the VC-8000/SETPOINT monitoring system. The system helps monitor the two faults causing the fires. The first is a loss of lubrication to the pump. The second is an axial displacement of the pump bearing. The VC-8000/SETPOINT has advantages for handling the refinery’s pump problems.
