Method for assembling a pelton turbine wheel |
摘要 |
The invention concerns a method which consists in: pre-positioning, in a housing (7) of a flange (5), a bucket (2) supported by part (23c) of its outer surface (23) against an edge (71) of the housing (7) providing a space (E') betwen the convex surface (23B) of the outer radial part (2B) of the bucket (2) and said edge (71); producing an articulated linkage (15) of the bucket (2) on the rim (1) and/or the flange (5) on the inside (2A) of the bucket (2); exerting on the outer radial part (2B) of the bucket (2) a first calibrated force to bring it closer to the edge (71); determining the distance (e) between said outer radial part (2B) and said edge (71) under said force; slackening said force; arranging, between said outer radial part (2B) and said edge (71), a wedge (53) having a thickness substantially equal to said distance (e); and exerting on the outer radial part (2B) of the bucket a second force (F2) to bringing it closer to the edge and maintaining said second force (F2) which has an intensity not less than that of the first force.
