Abstract
The ventilation assembly designed to cool a stator ring (1) of a turbine machine, finishes on gas blower manifolds (3) composed of symmetric half-shells (7 and 8) attached by welding at their opposite edges and joined together by distributors (4) composed mainly of cylindrical coils acting as spacers placed between the manifolds (3) and welded to them. Finally, the flexible support means comprise rules (6) to complete the assembly of the manifolds to the ring (1).
Claims7
Stator ring (1) ventilation assembly (2) composed of branched pipes comprising feed pipes (5), distributors (4) and manifolds (3) adjacent to the ring and provided with drillings (12) through which gas is blown towards the ring, characterized in that the manifolds are composed of pairs of half-shells (7, 8) comprising an end plate (9) and a rim (10) surrounding the end plate, the pairs of half-shells being attached by the rims, the distributors comprise coils (15) forming spacers between the manifolds and provided with ends (16) arranged to be adjusted to openings (13) in the side parts (14) of the end plates.
