Process for assembling a pelton-type turbine wheel, wheel vane, and, pelton-type turbine wheel

摘要

"PROCESS FOR ASSEMBLY OF A PELTON TYPE TURBINE WHEEL, WHEEL REED, AND, PELTON TYPE TURBINE WHEEL". This process consists of: pre-positioning, in a housing (7) of a flange (5), a reed (2) in support by a part (23C) of its external surface (23) against an edge (71) of the housing (7), providing a space (E ') between the convex surface (23B) of the outer radial part (2B) of the reed (2) and this edge (71); producing an articulated connection (15) of the reed (2) on the rim (1) and / or the flange (5) on the inner side (2A) of the reed; exert, on the outer radial part (2B) of the reed (2), a first calibrated approaching effort in relation to the edge (71); determining the distance e) between this external radial part (2B) and this edge (71) under said effort; release that effort; disposing, between this external radial part (2B) and this edge (71), a wedge (53) of thickness approximately equal to the said distance (UM and MV); and exert a second effort (F ~ 2 ~) on the outer radial part (2B) of the approach to the edge (71), and maintain this second effort (F ~ 2 ~) having an intensity greater than or equal to that of the first effort.
