    Abstract: A method for protecting a turbomachine from corrosion may include creating a first sand mold in a drag of a casting flask, coupling a cope of the casting flask to the drag, removing the runner pin and the at least one riser pin from the cope to expose a runner and at least one riser, respectively, and pouring a molten first material in the runner to cast a first component of the turbomachine. The method may further include removing the first sand mold, creating a second sand mold utilizing the first component in the drag, coupling the cope to the drag, removing the runner pin and the at least one riser pin from the cope to expose a runner and at least one riser, respectively, and pouring a molten second material in the runner to cast a second component of the turbomachine integral with the first component.

    Abstract: A rotor system for a rotating machine, including a rotating shaft, an auxiliary bearing, and a primary bearing configured to provide a bearing and seal combination. The auxiliary bearing may include a support structure extending around a circumference of the rotating shaft, such that an annular gap is defined between the support structure and the rotating shaft when the primary bearing supports the rotating shaft. The auxiliary bearing may also include a first pedestal extending radially-inward from the support structure, and first and second beams extending from opposite sides of the first pedestal in a plane perpendicular to an axis of the shaft. The auxiliary bearing may further include a first roller operatively coupled to the first beam, and a second roller operatively coupled to the second beam, such that the first and second rollers are configured to engage the shaft.

    Abstract: A sealing system for process gas leakage from a turbomachine casing is provided. The sealing system may include a seal assembly housing coupled to or integral with the turbomachine casing. The seal assembly housing defines a bore configured to receive a rotary shaft and a sealing assembly. The sealing assembly includes a plurality of carbon rings mounted circumferentially about the rotary shaft. The plurality of carbon rings may include an inboard carbon ring configured to prevent flow of a separation gas inboard of the barrier seal, an outboard carbon ring configured to prevent flow of contaminates into the seal assembly housing, and an intermediate carbon ring interposed between the inboard carbon ring and outboard carbon ring. A pressure differential is maintained across the inboard carbon ring, such that the separation gas is prevented from flowing inboard across the inboard carbon ring by a residual portion of a seal gas.

    Abstract: A reciprocating compressor includes a compressor cylinder defining a cylinder wall, a valve bore formed in the cylinder wall, and a compressor valve assembly arranged in the compressor cylinder. The compressor valve assembly includes a valve liner having a liner body and a liner flange disposed at an end of the liner body. The liner body is disposed in the valve bore. The liner flange is positioned in contact with the compressor cylinder. A valve seat is coupled to an inner surface of the liner body. The valve seat has a seating surface formed at an end of the valve seat. A compressor valve is positioned on the seating surface of the valve seat. A valve cage is positioned on the compressor valve. A valve cover is coupled to the valve cage to apply a bias force to retain the compressor valve on the seating surface of the valve seat.

    Abstract: A platform seal and damper assembly for turbomachinery (100), such as fluidized catalytic cracking (FCC) expanders or gas turbine engines; and methodologies for forming such assembly are provided. An axially-extending groove (160) is arranged on a side (162) of a respective platform. Groove (160) is defined by a radially-outward surface (168) at an underside of the platform and a surface (170) extending with a tangential component (T) toward radially-outward surface (168). A seal and damper member (152) is disposed in groove (160), where the body of seal and damper member has adjoining surfaces (190, 188) configured to respectively engage, in response to a camming action, with the surfaces (168, 170) that define the axially-extending groove. The camming action being effective to produce an interference fit of the seal and damper member (152) with the side of the respective platform (162) and an opposed side (163) of an adjacent platform.
