Stator ring ventilation assembly
View Patent ↗An assembly for ventilating a stator ring having branched pipes that include feed pipes, distributors, and a plurality of manifolds adjacent to the stator ring and provided with drilled holes. The distributors connect the feed pipes to the plurality of manifolds, and the plurality of manifolds include pairs of half-shells, each of the half-shells including an end plate having an opening and a rim surrounding the end plate, and the half-shells in each of the pairs being joined to each other at the rims. The distributors include ducts mounted between adjacent ones of the plurality of manifolds and have open ends fitted into openings of the end plates and have abutment portions to the end plates.
1. An assembly for ventilating a stator ring, comprising:
branched pipes comprising:
feed pipes,
distributors, and
a plurality of manifolds configured to be provided adjacent to the stator ring and provided with drilled holes, wherein the distributors connect the feed pipes to the plurality of manifolds;
the plurality of manifolds further comprising pairs of half-shells, each of the half-shells including an end plate having an opening and a rim surrounding the end plate, and the half-shells in each of the pairs being joined to each other at the rims; and
the distributors including at least one duct mounted between adjacent manifolds of the plurality of manifolds, said at least one duct having open ends fitted into openings of end plates of said adjacent manifolds and said at least one duct having collars that separate said adjacent manifolds.
2. The assembly according to claim 1 wherein a width of at least one rim of a pair of half-shells of said pairs of half-shells is different than a width of a rim of another pair of half-shells of said pairs of half-shells.
3. The assembly according to claim 1 , further comprising:
ribs configured to be provided on the stator ring; and
V-notches that support the ducts.
4. The assembly according to claim 1 , further comprising:
rods configured to be mounted on the stator ring, and the rods covering and crossing the plurality of manifolds.
5. The assembly according to claim 4 , wherein the rods are configured to be mounted to the stator ring by elastic connections.
6. The assembly according to claim 5 , wherein the elastic connections are configured to slide in an axial direction.
7. The assembly according to claim 1 , wherein the feed pipes are respectively connected to the plurality of manifolds such that said feed pipes penetrate into the open ends of said plurality of manifolds and seals are disposed between said feed pipes and said open ends of said plurality of manifolds.
8. The assembly according to claim 1 , wherein the drilled holes of the plurality of manifolds are configured to be located adjacent to said stator ring.
9. The assembly according to claim 1 , wherein the drilled holes are configured to blow gas out towards the stator ring.
10. An assembly comprising:
at least one distributor;
a plurality of manifolds provided with drilled holes, wherein the at least one distributor connects the plurality of manifolds;
the plurality of manifolds further comprising pairs of half-shells, each of the half-shells including an end plate and a rim, the end plate having an opening connected to the at least one distributor, and pairs of half-shells being joined to each other at corresponding rims to form the plurality of manifolds; and
the at least one distributor including ducts mounted between adjacent ones manifolds of the plurality of manifolds, at least a duct of said ducts having open ends fitted into openings of end plates of said adjacent manifolds and said at least one duct having collars that separate said adjacent manifolds.
11. The assembly of claim 10 , wherein at least a width of a rim of a pair of half-shells of said pairs of half-shells is different than a width of a rim of another pair of half-shells of said pairs of half-shells.
12. The assembly of claim 10 , further comprising:
V-notches that support the ducts.
13. The assembly of claim 10 , further comprising:
rods configured to be mounted on a stator ring, and the rods covering and crossing the plurality of manifolds.
14. The assembly of claim 13 , wherein the rods are configured to be mounted on the stator ring by elastic connections.
15. The assembly of claim 14 , wherein the elastic connections are configured to slide in an axial direction.
16. The assembly of claim 10 , wherein feed pipes are connected to the plurality of manifolds such that the feed pipes penetrate into the open ends of said plurality of manifolds and seals are disposed between the feed pipes and the open ends of the plurality of manifolds.
17. The assembly of claim 10 , wherein the drilled holes are configured to blow gas out towards a stator ring that is encircled by the plurality of manifolds.
