ABSTRACT:
An earth and sand wear resisting hydraulic machine disposed in pressurized water and having movable guide vanes, has a wear resisting material against earth and sand applied by spraying or welding to the front end of a vane body of each guide vane, to the surface of a vane body portion located below the center of a water flowing portion of the vane body and to upper and lower end faces of the vane body. Consequently, the guide vanes and end faces are protected against wear caused by earth and sand.
