摘要： One method empirically determines a stiffness value for each of two or more different subsets of the bristles of a brush seal, then calculates a variation in stiffness, and then identifies the brush seal as defective if the calculated variation in stiffness exceeds a predetermined stiffness variation criteria. One apparatus includes a load transducer having a contact head sized to contact less than twenty percent of the bristles, a displacement transducer which measures the displacement of the free ends of the contacted bristles, and a clamp for securing the brush seal and presenting the bristles for contact.

摘要： A seal assembly and a rotary machine, such as a steam turbine, containing the seal assembly. A casing circumferentially surrounds a rotor and includes a circumferential channel open to the rotor. Seal segments are circumferentially arrayed in the channel and are movable between radially inward and outward positions. Circumferentially adjacent seal segments have circumferentially opposing surface grooves. A resilient and imperforate member is engaged in the grooves of circumferentially-adjacent seal segments circumferentially urging apart such segments and providing sealing between such segments.

摘要： A brush seal is provided between a first stationary component and a second rotating component. A cooling medium is provided through a plurality of jet nozzles for flow along an upstream surface portion of the brush seal bristles and along the rotating component surface adjoining the tips of the bristles. The cooling medium cools the brush seal bristles to a temperature below the temperature of the working fluid passing through the turbine. The jet nozzles may be arranged in the shroud or in the upstream backing plate of the brush seal to direct the cooling medium toward the juncture of the brush seal and the sealing surface.

摘要： A number of sealing segments 20 mounts a brush seal about a rotor. The tips of the brush seal 46 are maintained out of contact with the rotor surface throughout the entire operating range of the turbomachinery. Thus, the increase in temperature resultant from rubs between the bristle tips and the rotor 12 which effectively increase vibrations of the turbomachinery are eliminated. Brush seals are therefore maintained out of contact with the rotor throughout the entire operating range of the turbomachinery and thus do not affect the dynamic behavior of the rotor.

摘要： Circumferentially extending sealing segments (45) are disposed about a rotary component (16) and have seal face (34) carrying a plurality of labyrinth seal teeth (36) and a brush seal (37). The segments are movable between large and small clearance positions relative to the rotor at start-up and steady-state operating conditions, respectively. In one form, springs (31) bias the segments radially outwardly at start-up and steam pressure displaces the segments to the small clearance positions at steady-state operations. In a further embodiment, springs bias the segment for movement to the small clearance position, the extent of movement being determined by thermal expansion of centering rings mounting the segments to the stationary components.

摘要： A self-centering brush seal is disposed in an annular groove formed in a stationary component about a rotatable component, the stationary and rotatable components having a common axis. The brush seal includes a plurality of bristles projecting into sealing engagement with the rotating component. The brush seal has a radial clearance in the groove enabling the brush seal for free-floating radial excursions within the groove to maintain concentricity with the rotary component notwithstanding deviation of the axis of rotation of the rotating component relative to the axis of the fixed component. In another form, the brush seal comprises a plurality of arcuate segments having a helical coil spring biasing the segments for radial movement enabling the tips of the bristles to seal against the rotatable component. In a further embodiment, leaf springs bias each segment to maintain its bristles in engagement with the rotatable component. In a still further embodiment, the seal segments are pressure balanced in a radial direction with an O-ring seal sealing high and low pressure regions on opposite sides of the segments.

摘要： A brush seal segment useful, when circumferentially arrayed with other such segments, to seal the gap between a rotor and a surrounding casing of a rotary machine such as a steam turbine. An annular backing plate has a rim radially-inwardly bounding together upstream-facing and downstream-facing surfaces. Canted bristles abut the upstream-facing surface. The rim is designed to allow the bristles to recover from a rotor rub. In one design, the rim acts as a labyrinth-seal tooth and is shaped to deform, under a radial force, longitudinally away from the upstream-facing surface. In another design, the rim has a more-inwardly projecting second portion near a radially-aligned edge, and only this second portion acts as a labyrinth-seal tooth.

摘要： A brush seal which, among other applications, may be used for sealing a steam leakage gap between a steam turbine rotor and a steam turbine casing. A brush seal backing plate has a surface which includes adjacent first and second areas. First and second bristle packets contact and generally cover, respectively, the first and second areas. A first anti-hysteresis plate is positioned between and contacts the first and second bristle packets, is aligned generally perpendicular to the backing plate, and is proximate and generally spaced apart from the backing plate. The anti-hysteresis plate restores the bristles which would otherwise become set in a non-sealing position against the backing plate because of transient events such as thermal differential growth or relative movement of the rotor and casing.
