A nuclear power plant had changed bus duct cooling fan bearings approximately five times in two years. The plant wanted to find the root cause of the failures so they could address the main problem instead of changing out bearings more frequently. The increased replacement frequency brought increased cost and unscheduled maintenance.
A major pump OEM called on MSI to help resolve multiple pump driveshaft failures for an ore mining company in East Africa.
To identify potential opportunities for early bearing failure, MSI performed experimental modal analysis (EMA) and operational deflection shape (ODS) tests on a prototype unit for the manufacturer.
