摘要： The present invention provides, in one embodiment, an annular turbine seal for disposition in a turbine between a rotatable component having an axis of rotation and a turbine housing about the same axis of rotation. The turbine seal has a plurality of arcuate seal carrier segments that have an abradable portion secured to the seal carrier segments. In addition, at least one spring is disposed on the seal carrier segment to exert a force and maintain the seal carrier segment adjacent to the rotatable component.

摘要： A brush seal segment is mounted within a pressure vessel and against an arcuate surface of an element to provide a seal between regions on opposite sides of the seal at different pressures. By vibrating the vessel through a range of frequencies, natural frequencies of the brush seal under pressure loading can be ascertained. Additionally, by adjusting interference between the arcuate surface and the bristle tips, natural frequencies of the brush seal under various interference loadings can likewise be ascertained. The pressure vessel has mounts for attaching the vessel to a shaker table to facilitate vibrating the vessel through the range of frequencies.

摘要： A rotary machine includes a rotatable rotor, blades radially mounted on and spaced apart about the rotor, a stationary casing disposed about and radially outward from the rotor and blades defining an annular gap between the casing and tips of the blades, and a flexible abradable seal assembly attached on the casing and disposed within the annular gap such that during differential growth of the rotor and blades relative to the casing the seal assembly flexes and abrades in response to contact by the blade tips and thereby clearance between the casing and blade tips is controlled as to avoid contact by the moving blade tips with the casing.

摘要： In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner rail of the nozzle segment on a lower pressure side of the chordal hinge seal. The supplemental seal comprises a segmented annular composite tubular woven compliant seal disposed in a cavity along a sealing surface of the inner rail of the segment. The seal bears against the annular sealing surface of the nozzle support ring, which compresses the seal. Because of the compliant nature of the seal, a supplemental seal is formed on the low pressure side of the chordal hinge seal.

摘要： In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner band of the nozzle segment on a high pressure side of the chordal hinge seal. The supplemental seal includes a pair of sheet metal shims overlaid by a woven metallic cloth supported by a bracket secured to the inner margin of the inner rail. The radially inner end of the cloth seal bears against the annular sealing surface of the nozzle support ring. The shims of the legs of the supplemental seal are slit along their distal margin and staggered circumferentially relative to one another to provide flexibility and effective sealing engagement with the nozzle support ring.

摘要： In a gas turbine having a chordal hinge seal between an inner rail of each nozzle segment and an annular axially facing sealing surface of a nozzle support ring, a supplemental seal is disposed between the support ring and inner band of the nozzle segment on a lower pressure side of the chordal hinge seal. The supplemental seal includes a flexible sheet metal seal having a margin secured in a groove of the inner rail of the nozzle segments with a bent-over edge to form a seal therewith. The opposite margin has an edge which bears against the axially opposed sealing surface of the nozzle support ring. Leakage flow past the chordal hinge seal exerts sealing pressure against the preloaded flexible seal to maintain the seal between the sealing surfaces of the support ring and segments. The supplemental seal extends circumferentially and spans the joint between adjacent nozzle segments.

摘要： A flexible magnetic brush seal is employed as a low flow fluid film seal and/or a diffusion and mass transfer prevention seal in a hydrogen generator to seal between a hydrogen atmosphere and a fluid on an opposite side of the seal. The brush seal is formed of a magnetic rubber flexible material, enabling the seal to be flexed and altered in dimension to fit a number of different sealing environments of different dimensions. The magnetic properties of the brush seal enable temporary securement of the brush seal to a brush seal holder prior to final securement.

摘要： Upper and lower halves of the inner barrel of a compressor for a turbine are bolted to one another along a horizontal midline joint with metal-to-metal surface contact. Elongated grooves are provided in the margin of one of the barrel halves. Elongated composite tubular woven seals are provided in the grooves, the seals having a diameter in excess of the depth of the grooves. The seals comprise an inner woven metal core surrounded by an annular silica fiber layer, in turn surrounded by a metal foil with an outer protective covering of a braided stainless steel. Upon joining the upper and lower halves, the compliant seal is crushed within the groove, maintaining a seal between the barrel halves in the event of warpage of the compressor casing during turbine operation.
