Abstract: This method can be used for refurbishing a facility for converting hydraulic energy into electrical or mechanical energy, and vice versa. The facility includes a Francis type pump-turbine. The pump-turbine includes a runner movable about an axis, a pre-distributor, including stay vanes defining between each pair of two adjacent stay vanes a first water passage channel and a distributor, including guide vanes arranged downstream of the stay vanes in the direction of water flow feeding the pump-turbine operating in turbine mode. The guide vanes define between each pair of two adjacent guide vanes a second water passage channel. This method includes steps of reducing the height, taken parallel to the axis of rotation of the runner, of the first water passage channels and reducing the height, taken parallel to the axis of rotation of the runner, of the second water passage channels.

Abstract: The invention relates to an adjustable system for guiding the rotation of a shaft about a vertical axis, including skids, each of which is provided with a surface for forming a bearing with the shaft. For each skid, a shim is provided with a cam surface, the outline of which, in a plane that is radial relative to the vertical axis of rotation, is inclined relative to said axis. Each skid directly engages, via a portion of the outer radial surface thereof, with the cam surface of the shim. Equipment for converting hydraulic power into electrical power according to the invention includes a wheel that is rotatably secured to a shaft guided by such an adjustable system.
