Abstract

Sealing device for providing seals between adjacent components, and turbomachines utilizing such sealing devices, are provided. A sealing device includes a seal plate insertable between the adjacent components, the seal plate comprising a first face and an opposing second face. The sealing device further includes a plurality of pins extending from one of the first face or the second face, the plurality of pins configured to space the one of the first face or the second face from contact surfaces of the adjacent components.

First claim

What is claimed is:

1. A sealing device for providing a seal between adjacent components, the sealing device comprising:
seal plate insertable between the adjacent components, the seal plate comprising a first face and an opposing second face and an edge defining a periphery of the seal plate, the seal plate defining a width and a length; and
a plurality of pins extending from one of the first face or the second face, the plurality of pins spaced apart from the edge of the seal plate and spaced apart from one another along the width and the length of the seal plate to define space for a cooling medium to flow between the plurality of pins, the plurality of pins configured to space the one of the first face or the second face from contact surfaces of the adjacent components,
wherein the plurality of pins and the seal plate are made as one continuous piece of material; and
wherein the plurality of pins are arranged in at least three rows of pins and at least three columns of pine.

2. The sealing device of claim 1 , wherein a channel is defined in the one of the first face or the second face, the plurality of pins disposed within the channel, and wherein the channel extends along the length of the seal plate.

3. The sealing device of claim 1 , wherein a channel is defined in the one of the first face or the second face, the plurality of pins disposed within the channel, and wherein the channel extends along the width of the seal plate.

4. The sealing device of claim 1 , further comprising an auxiliary seal member disposed on the plurality of pins and spaced from the seal plate, the auxiliary seal member configured to contact the contact surfaces of the adjacent components.

5. The sealing device of claim 4 , wherein the auxiliary seal member is a second seal plate.

6. The sealing device of claim 4 , wherein the auxiliary seal member comprises a cloth layer, the cloth layer comprising a cloth and a plurality of metallic strands embedded in the cloth.

7. The sealing device of claim 1 , wherein each of the plurality of pins has a maximum height of less than or equal to approximately 0.01 inches.

8. The sealing device of claim 1 , wherein each of the plurality of pins has a maximum width of less than or equal to approximately 0.02 inches.

9. The sealing device of claim 1 , wherein each of the plurality of pins is generally cylindrical.

10. The sealing device of claim 1 , wherein each of the plurality of pins is generally pyramidal.

11. The sealing device of claim 1 , further comprising an auxiliary seal member disposed on distal ends of the plurality of pins such that the auxiliary seal member is spaced from the one of the first face or the second face from which the plurality of pins extend.

12. A turbomachine, comprising:
a first component and a second adjacent component, the first and second components defining a gap therebetween, each of the first and second components defining a slot, the slot comprising a contact surface; and
a sealing device disposed in the gap and providing a seal between adjacent components, the sealing device comprising:
a seal plate disposed within the slots of the first and second components and extending across the gap, the seal plate comprising a first face and an opposing second face and an edge defining a periphery of the seal plate, the seal plate defining a width and a length; and
a plurality of pins extending from one of the first face or the second face, the plurality of pins spaced apart from the edge of the seal plate and spaced apart from one another along the width and the length of the seal plate to define a space for a cooling medium to flow between the plurality of pins, the plurality of pins spacing the one of the first face or the second face from the contact surfaces of the slots,

wherein the plurality of pins and the seal plate are made as one continuous piece of material; and
wherein each of the plurality of pins is generally cylindrical.

13. The turbomachine of claim 12 , further comprising an auxiliary seal member disposed on the plurality of pins and spaced from the seal plate, the auxiliary seal member configured to contact the contact surfaces of the adjacent components.

14. The turbomachine of claim 13 , wherein the auxiliary seal member is a second seal plate.

15. The turbomachine of claim 13 , wherein the auxiliary seal member comprises a cloth layer, the cloth layer comprising a cloth and a plurality of metallic strands embedded in the cloth.

16. The turbomachine of claim 12 , wherein each of the plurality of pins has a maximum height of less than or equal to approximately 0.01 inches.

17. The turbomachine of claim 12 , wherein each of the plurality of pins has a maximum width of less than or equal to approximately 0.02 inches.

18. A sealing device for providing a seal between adjacent components, the sealing device comprising:
seal plate insertable between the adjacent components, the seal plate comprising a first face and an opposing second face and an edge defining a periphery of the seal plate, the seal plate defining a width and a length; and
a plurality of pins extending from one of the first face or the second face, the plurality of pins spaced apart from the edge of the seal plate and spaced apart from one another along the width and the length of the seal plate to define space for a cooling medium to flow between the plurality of pins, the plurality of pins configured to space the one of the first face or the second face from contact surfaces of the adjacent components,
wherein the plurality of pins and the seal plate are made as one continuous piece of material; and
wherein a channel is defined in the one of the first face or the second face, the plurality of pins disposed within the channel.

19. The sealing device of claim 18 , wherein the channel extends along the length of the seal plate.

20. The sealing device of claim 18 , wherein the channel extends along the width of the seal plate.
