Abstract
A sealing assembly, which is mounted at a rear end of an impeller, and a turbo machine including the sealing assembly is provided, the sealing assembly includes a rotation body having a ring shape that surrounds a shaft coupled with the impeller at the rear end of the impeller; and an extension portion extending from the rotation body to the rear end of the impeller, such that an inner space is formed between the rotation body and the rear end of the impeller, wherein the extension portion is sealingly coupled with the rear end of the impeller
Claims20
A sealing assembly, which is mounted at a rear end of an impeller, the sealing assembly comprising:
- a rotation body having a ring shape that surrounds a shaft coupled with the impeller at the rear end of the impeller;
- and
- an extension portion extending from the rotation body to the rear end of the impeller, such that an inner space is formed between the rotation body and the rear end of the impeller,
- wherein the extension portion is sealingly coupled with the rear end of the impeller.
A turbomachine, comprising:
- an impeller configured to rotate at a high speed to suck a fluid;
- a shaft coupled with the impeller at a rear end of the impeller and configured to integrally rotate together with the impeller;
- and
- a sealing assembly provided at the rear end of the impeller to reduce a thrust applied to the impeller,
- wherein the sealing assembly includes:
- a rotation body having a ring shape that surrounds the shaft;
- and
- an extension portion extending from the rotation body to the rear end of the impeller such that an inner space is formed between the rotation body and the rear end of the impeller, and
- wherein the extension portion is sealingly coupled with the rear end of the impeller.
A sealing assembly, which is mountable at a rear end of an impeller, the sealing assembly comprising:
- a rotation body having a ring shape that is configured to surround a shaft coupled with the impeller at the rear end of the impeller;
- and
- an extension portion extending from the rotation body in a direction corresponding to a rear end of the impeller when the ring shape of the rotation body surrounds the shaft, such that the extension portion is configured to form an inner space between the rotation body and the rear end of the impeller,
- wherein the extension portion is configured to be sealingly coupled with the rear end of the impeller.
