Sealing devices for Kaplan and Francis hydropower turbines are critical components that assure reliable operation and environmental compliance. Those working with these turbines in the hydropower industry are discovering that using mechanical split seals for main shaft sealing can make significant advances in their operations. In today’s post, we interview John Sousa, a Chesterton expert […]
Combating Corrosion in Hydropower Facilities with Protective Coatings
If you are operating a hydroelectric facility, you are most likely in an isolated region where the reliability of plant systems is paramount. The lack of easy access to spare parts, heavy equipment, and skilled maintenance staff requires careful planning and advanced preparation. Since plant up-time is especially critical you need to be able to […]
Kaplan Turbine Sealing: Troubleshooting Leakage
About Kaplan Turbines The Kaplan turbine is one of the most commonly used turbines types in hydropower facilities around the globe. This “reaction type” propeller turbine is an evolution of the Francis turbine. It has adjustable blades and/or wicket gates (single- or double-regulation systems) to obtain optimal efficiency in different pressure/head conditions. It operates at efficiencies up to […]
