Abstract
A rotational equipment assembly includes a brush seal and a clip. The brush seal extends axially along an axis from a base end to a tip end. The brush seal extends circumferentially about the axis. The brush seal includes an inner plate, an outer plate and a bristle pack disposed radially between the inner plate and the outer plate. The bristle pack is bonded to the inner plate and the outer plate at the base end. The bristle pack projects axially along the axis away from the inner plate and the outer plate to the tip end. The clip includes a base, an inner leg and an outer leg. The base wraps around the brush seal at the base end. The inner leg projects radially outward from the base to the outer leg. The outer leg projects axially along the axis out from the inner leg towards the tip end.
Claims19
An assembly for rotational equipment, comprising:
- a brush seal extending axially along an axis from a base end to a tip end, the brush seal extending circumferentially about the axis, the brush seal including an inner plate, an outer plate and a bristle pack disposed radially between the inner plate and the outer plate, the bristle pack bonded to the inner plate and the outer plate at the base end, and the bristle pack projecting axially along the axis away from the inner plate and the outer plate to the tip end;
- and
- a clip including a base, an inner leg and an outer leg, the base wrapping around the brush seal at the base end, the inner leg projecting radially outward from the base to the outer leg, and the outer leg projecting axially along the axis out from the inner leg towards the tip end;
- wherein the outer leg projects axially along the axis out from the inner leg to a distal end;
- and
- wherein the distal end is axially recessed from the tip end.
An assembly for rotational equipment, comprising:
- a brush seal extending axially along an axis from a base end to a tip end, the brush seal extending circumferentially about the axis, the brush seal including an inner plate, an outer plate and a bristle pack disposed radially between the inner plate and the outer plate, the bristle pack bonded to the inner plate and the outer plate at the base end, and the bristle pack projecting axially along the axis away from the inner plate and the outer plate to the tip end;
- and
- a sheet metal clip including a channel, a radial leg and an axial leg, the brush seal seated in the channel at the base end, the radial leg projecting radially outward away from the brush seal to the axial leg, and the axial leg projecting out from the radial leg, in an axial direction towards the tip end, to a distal end that is axially recessed from the tip end.
An assembly for rotational equipment, comprising:
- a brush seal extending axially along an axis from a base end to a tip end, the brush seal extending circumferentially about the axis, the brush seal including an inner plate, an outer plate and a bristle pack disposed radially between the inner plate and the outer plate, the bristle pack bonded to the inner plate and the outer plate at the base end, and the bristle pack projecting axially along the axis away from the inner plate and the outer plate to the tip end;
- and
- a clip comprising sheet metal configured with an inner wall, an outer wall, an endwall, an offset flange and a locator flange, the inner wall projecting axially out from an inner end of the endwall along the inner plate to a first edge of the sheet metal, the outer wall projecting axially out from an outer end of the endwall along the outer plate, the endwall axially engaging the brush seal at the base end, the offset flange projecting radially outward from the outer wall to the locator flange, and the locator flange projecting axially out from the offset flange to a second edge of the sheet metal;
- wherein the brush seal extends at least three-hundred and forty degrees circumferentially about the axis between opposing circumferential ends of the brush seal with a brush seal gap formed by and extending circumferentially between the opposing circumferential ends of the brush seal;
- wherein the clip extends at least three-hundred and forty degrees circumferentially about the axis between opposing circumferential ends of the clip with a clip gap formed by and extending circumferentially between the opposing circumferential ends of the clip;
- and
- wherein the clip gap is circumferentially offset from the brush seal gap.
