Power | Northeastern Power Company

Problem:

This municipal utility lost an l.D. Fan due to bearing failure during the month of January, one of the most demanding periods as far as power generation goes. After a Robinson inspection, it was determined that the thrust ring had spun in the shaft groove, destroying both the ring and the shaft groove.

Solution:

Robinson Fans Service, with specialized field machining equipment, arrived on the job site and machined the shaft groove to accept a specially designed thrust ring (which was also designed by our on-site technician). After modification and installation, the unit was reassembled and put back into service.

Result:

The generation plant was down only a mini mum of time and repaired at a fraction of the cost compared to the alternative of removing the entire fan wheel assembly and sending out for repairs.
