The Researching Actuality and Developing Trend of Inspection and Repair Equipments on Water Turbine Runners

The water turbine is the great machine that translates the kinetic energy and potential energy into electricity.When it is running in high speed,the blades are wrecked by abrasion and cavitation.The examination and repair equipments of water turbine runners,and its present application and research condition at home and abroad were introduced completely and systematically in this article ,and the trend of its development was also predicted from practicality.
