Carbon seal covers
A compression tool for a seal assembly of a gas turbine engine includes a cover configured to be installed to a seal assembly. The seal assembly includes a seal carrier, a seal element installed to the seal carrier, the seal element configured as a ring, and one or more biasing elements configured to axially bias a position of the seal element. The cover includes a cover body, and a cover flange including a flange groove configured to cover the seal element of the seal assembly.
1. A compression tool for a seal assembly of a gas turbine engine, comprising:
a cover configured to be installed to a seal assembly, the seal assembly including:
a seal carrier;
a seal element installed to the seal carrier, the seal element configured as a ring, and extending in a first axial direction from the seal carrier; and
one or more biasing elements extending from the seal carrier in a second axial direction and configured to axially bias a position of the seal element toward the first axial direction;
the cover including:
a cover body; and
a cover flange including a flange groove configured to cover the seal element of the seal assembly and to urge the seal carrier in the second axial direction.
2. The compression tool of claim 1 , wherein the flange groove has a cross-sectional shape to match a cross-sectional shape of the seal element.
3. The compression tool of claim 1 , wherein the cover includes a cover rim disposed radially outboard of the flange groove and configured to interface with the seal carrier radially outboard of the seal element.
4. The compression tool of claim 1 , further comprising:
a threaded rod extending through the cover via a cover opening;
a knob installed to the threaded rod and configured to be tightened to the cover.
5. The compression tool of claim 4 , wherein tightening of the knob is configured to overcome a biasing force of the one or more biasing elements.
6. The compression tool of claim 1 , wherein the one or more biasing elements are one or more springs.
7. The compression tool of claim 1 , wherein the cover body is configured to be disposed radially inboard of the seal element.
8. A seal assembly and compression tool arrangement of a gas turbine engine, comprising:
a seal assembly, including:
a seal carrier;
a seal element installed to the seal carrier, the seal element configured as a ring, and extending in a first axial direction from the seal carrier; and
one or more biasing elements extending from the seal carrier in a second axial direction and configured to axially bias a position of the seal element toward the first axial direction; and
a cover assembly installed to the seal assembly, including:
a cover body; and
a cover flange including a flange groove configured to cover the seal element of the seal assembly and to urge the seal carrier in the second axial direction.
9. The arrangement of claim 8 , wherein the cover assembly is installed to the seal assembly in an axial direction.
10. The arrangement of claim 8 , wherein the flange groove has a cross-sectional shape to match a cross-sectional shape of the seal element.
11. The arrangement of claim 8 , wherein the cover includes a cover rim disposed radially outboard of the flange groove and configured to interface with the seal carrier radially outboard of the seal element.
12. The arrangement of claim 8 , further comprising:
a threaded rod extending through the cover via a cover opening;
a knob installed to the threaded rod and configured to be tightened to the cover.
13. The arrangement of claim 12 , wherein tightening of the knob is configured to overcome a biasing force of the one or more biasing elements.
14. The arrangement of claim 8 , wherein the one or more biasing elements are one or more springs.
15. The arrangement of claim 8 , wherein the cover body is configured to be disposed radially inboard of the seal element.
16. A method of disassembling a seal assembly of a gas turbine engine, the seal assembly including a seal carrier and a seal element installed to the seal carrier, the seal element configured as a ring, and extending in a first axial direction from the seal carrier, the method comprising:
installing a cover over the seal element of the seal assembly, the cover including:
a cover body; and
a cover flange including a flange groove configured to cover the seal element of the seal assembly; and
applying an axial force to the cover to overcome a biasing force of one or more biasing elements of the seal assembly and urge the seal carrier in a second axial direction opposite the first axial direction.
17. The method of claim 16 , further comprising:
installing the cover over a threaded rod via a cover opening in the cover;
installing a knob onto the threaded rod and tightening the knob to the cover.
18. The method of claim 17 , further comprising compressing the one or more biasing elements via the tightening of the knob.
19. The method of claim 16 , wherein the one or more biasing elements bias a position of the seal element in an axial direction.
20. The method of claim 16 , wherein the one or more biasing elements are one or more springs.
