Claims20
An assembly for rotational equipment, comprising:
- a metal seal carrier comprising a receptacle and a cylindrical carrier surface forming an outer peripheral boundary of the receptacle;
- and
- a carbon seal element seated in the receptacle, the carbon seal element comprising a cylindrical element surface that is brazed to the cylindrical carrier surface with a braze material, and the braze material disposed radially between the cylindrical element surface and the cylindrical carrier surface.
An assembly for rotational equipment, comprising:
- a metal seal carrier comprising a receptacle, an axial carrier surface and a radial carrier surface, the receptacle extending circumferentially within the metal seal carrier about an axis, the receptacle extending axially along the axis into the metal seal carrier to the radial carrier surface, and the receptacle extending radially within the metal seal carrier to the axial carrier surface;
- and
- a carbon seal element extending circumferentially about the axis and seated in the receptacle, the carbon seal element brazed to the metal seal carrier by a braze material disposed radially between the carbon seal element and the metal seal carrier.
An assembly for rotational equipment, comprising:
- a metal seal carrier comprising a receptacle and a cylindrical carrier surface forming a peripheral boundary of the receptacle within the seal carrier;
- a carbon seal element seated in the receptacle, the carbon seal element comprising a cylindrical element surface, and a gap formed radially between the cylindrical carrier surface and the cylindrical element surface;
- and
- bonding material disposed, in the gap, radially between the cylindrical carrier surface and the cylindrical element surface, and the bonding material bonding the carbon seal element to the metal seal carrier.
