摘要： An apparatus and method for protecting an inner radial surface of a housing of a turbomachine from corrosion. The method includes tapering the inner radial surface of the housing and a corresponding outer radial surface of a corrosion-resistant liner, and heating the housing to increase a diameter of the inner radial surface of the housing. The method also includes inserting the corrosion-resistant liner at least partially into the housing, and attaching the corrosion-resistant liner to the inner radial surface of the housing using a solid-state bonding process.

摘要： A method for fabricating a turbomachine component including a metal alloy with a layering device is provided. The method for fabricating the turbomachine component may include combining two or more elemental powders to form a powdered material. The method for fabricating the turbomachine component may also include forming a first metal alloy layer of the turbomachine component on a substrate. Forming the first metal alloy layer on the substrate may include melting a first portion of the powdered material to a first molten material with a heat source, mixing the first molten material with the heat source, and cooling the first molten material. The method for fabricating the turbomachine component may further include forming a second metal alloy layer of the turbomachine component on the first metal alloy layer, and binding the first metal alloy layer with the second metal alloy layer.

摘要： A casing assembly for a compressor where traditional inlet and discharge nozzles are replaced with a mounting surface created from weld filler material applied to the outside surface of a casing. The weld filler material, and a portion of the outside surface of the casing, are cooperatively milled to create a generally planar or flat surface having a casing conduit centrally-disposed therein. A flange may then be coupled to the flat surface for the inlet or discharge of a process gas.

摘要： An impeller may include a hub section, a plurality of blades, and a shroud. The hub section may be mounted on a rotatable shaft. The hub section may define a central opening for the rotatable shaft to extend therethrough and may define a plurality of holes disposed in a circular manner about the central opening. The plurality of blades may be connected to or integral with the hub section. The shroud may be connected to or integral with the hub section and the plurality of blades. The plurality of holes may be either through holes or partially drilled holes. A bottom of some or all of the partially drilled holes may be flat, conical, or rounded. Some or all of the partially drilled holes may have one or more bleed holes that may permit quenching material to flow therethrough and prevent the quenching material from stagnating therein.

摘要： An acoustic attenuator for a turbomachine and methodology for additively manufacturing the acoustic attenuator are provided. The acoustic attenuator includes an annular body (202) having an outer surface (204) and an inner surface (206). The inner surface of the annular body may define a bore (208) extending along a longitudinal axis (209) of the acoustic attenuator between a first end and a second end of the acoustic attenuator. The annular body may be formed by a plurality of axially-successive cross-sectional layers (e.g., 632, 634, 636) unitized between the first end and the second end of the acoustic attenuator. The plurality of axially-successive cross-sectional layers may be transversely disposed relative to the longitudinal axis of the acoustic attenuator. At least some axially-successive cross-sectional layers of the plurality of axially-successive cross-sectional layers (e.g., 632, 634, 636) defining a pocket (214) disposed between the outer surface and the inner surface of the annular body. At least a segment of a periphery of the pocket comprises two sides (2, 3) arranged to join at a common end point to form an apex (5) of the pocket.

摘要： A bearing and/or seal assembly (10) where pressurized gas (e.g., air) may be arranged to produce a contact-free bearing and/or seal is provided. The assembly includes a permeable body (12) including structural features (13) selectively engineered to convey a pressurized gas (Ps) from an inlet side (20) side of the permeable body to an outlet side (22) of the permeable body to form an annular film of the pressurized gas relative to the rotatable shaft. Disclosed embodiments may be produced by way of three-dimensional (3D) Printing/Additive Manufacturing (AM) technologies with practically no manufacturing variability; and may also cost-effectively and reliably benefit from the relatively complex geometries and the features and/or conduits that may be involved to, for example, form the desired distribution pattern or impart a desired directionality to the pressurized gas conveyed through the permeable body of the bearing and/or seal assembly.

摘要： A centrifugal compressor (20), with a shaftless impeller (50), is rotatively mounted on a journal. The journal is incorporated within a stationary journal shaft (40) that spans the impeller hub (52), or in a journal stub (80) that projects into at least one of the axial ends of the impeller hub, or in a pair of opposed, first and second journal stubs (142, 146). A magnetic bearing (60) is interposed between the journal and a hollow hub of the impeller. The journal and magnetic bearing support and position the impeller hub within an impeller cavity of the compressor casing (22). An independent impeller drive (151) rotates the impeller. A drive shaft (150), which is independent of the journal, is coupled to the impeller. Respective drive motor (300), rotor and stator permanent magnets, and/or electromagnetic coils are embedded within the respective, opposing journal and hub.
