Application of the EDS (Energy Dissipation System) The PRV valve is designed to rapidly divert the water flow away from the turbine into a turbine bypass system when the guide vane apparatus needs to perform a sudden manoeuvre (for [...]
Repair (in the process) of Francis turbine wicket gate (138MW HPP). Francis turbines are the most common water turbine used for electrical power production. Wicket gates around the outside of the turbine's rotating runner control the rate of water [...]
TURBINE RUNNER CAVITATION DAMAGE REPAIR Small bubbles can form at a pressure less than the vapor pressure of the water. If the vapor bubble collapses near the runner surface, highly localized pressure forces can remove runner material. This phenomenon, [...]
