The Cavitation and Abrasion Damage Condition of Hydraulic Turbine and Countermeasures in China

Abstract

In this paper, on the basis of presenting the foreground of the hydroelectric develepment and the cavitation and abrasion damage condition of hydraulic turbine in China, proposes the proposal to prevent cavitation and abrasion of turbine, and presents the works made by Gansu Electric Power Company in recent many yesrs to elevate the repair ability for hydroelectric power station in the silt_laden river. The requirements brought up in the research of the robot to repair hydraulic turbines at present were introduced.
