Specialist Bespoke Machining Solution for Largest Pumped Storage Power Station

To repair a 5.5-meter diameter pump-turbine regulating ring bearing and top cover journal face, in-situ, in one of Europe's largest pumped storage power stations while avoiding the need for a several week shutdown and lost generating time was the challenge for Furmanite. The phosphor bronze regulating ring bearing was found to be worn, and there was damage caused to the top cover vertical and horizontal journal faces by the bearing's retainer screws having worked loose. Furmanite developed its circular self-leveling milling technology to re-machine the top cover journal faces, and fit stainless steel liners as a counter face for the self-lubricating bearing.
