Apparatus for modifying geometry of at least one part of a turbine, hydraulic turbine and method of modifying a geometry of a part.

摘要

It is an apparatus for modifying the geometry of at least one part of a turbine which may include a housing assembly (3) including an outer housing which is shaped to modify the shape of a pre-existing element of a turbine. the outer shell (8) of the shell assembly (3) may be composed of a fiber reinforced polymeric material and may at least partially define an inner cavity. the outer casing (8) may be attached to a structure to modify the geometric shape of that structure. thereafter, a polymer molding (12) may be injected into the inner cavity by means of at least one injection port attached to the housing assembly. In some embodiments, one or more hardeners (9) and / or a core (10) may be positioned within the inner cavity to assist in enhancing the bonding of the polymer molding (12) to the housing (2) and / or in improving the molding. a structural property of the apparatus.
