Flexible Disc Coupling
Problem: In the past the customer used a hydraulic wrench to tension the coupling nuts. They experienced many problems with this method. It was considered expensive, time consuming and unsafe. Broken lines and broken sockets were a cause of problems, and the threads often galled when removing the nuts. Using the hydraulic wrench required three men and eight hours to torque 32 nuts. It was also difficult to torque the intermediate coupling because of clearance restrictions.
New Method: Superbolt Tensioners, 2 men / 5 man hours Product:
Superbolt CY-162-12/w
*Superbolt tensioners have also been used on 11,000 hp applications |
6000
hp Synchronous Motor driving a Centrifugal Compressor
Solution: Using
Superbolt Multi-Jackbolt Tensioners it took two men 2-1/2 hours
to install. This allowed the compressor to get back on line much
sooner and start producing product. The Superbolt Tensioners were
easy
to remove with no thread galling. The tensioners could then be
cleaned and reused.
