New Shaft Containment System Minimizes Turbine Vibrations

摘要

Two 2.5-MW twin horizontal Francis turbine units at the Twin Falls project near Manitouwadge, Ontario, Canada, experienced severe shaft vibration problems as soon as they were installed in January 2000. Engineers from Rapid-Eau Technologies of Cambridge, Ontario, which operates and maintains the plant, created a shaft containment system to solve the problem. Rapid-Eau Technologies' engineers have applied for a patent on the system.
