    摘要： A radial magnetic bearing may include an annular housing including a radial outer wall disposed between radially outer ends of two annular axial end plates and an isolation sleeve which may include a helical arrangement of a plurality of ferromagnetic wires. The isolation sleeve may be an annular structure extending axially between the two annular axial end plates, and the isolation sleeve and the annular housing may define an isolation cavity therebetween. The radial magnetic bearing may also include an isolation sleeve retainer configured to maintain a position of the isolation sleeve between the two annular axial end plates. The radial magnetic bearing may further include a plurality of laminations disposed adjacent the isolation sleeve and about a shaft of the rotating machine. A gap may be defined between the plurality of laminations and the isolation sleeve.

    摘要： An auxiliary bearing including a support structure extending at least partially around a circumference of a shaft. A first pedestal may extend in a radially-inward direction from the support structure. First and second beams may extend from opposite sides of the first pedestal in a plane perpendicular to an axis of the shaft. First and second rollers may be operatively coupled to the first and second beams, and the first and second rollers may be configured to engage the shaft.

    摘要： A cooling system for a motor-compressor and a method for cooling the motor-compressor are provided. The cooling system may include a discharge assembly having a hub portion disposed radially outward of a rotary shaft of the motor-compressor. A plurality of arms may be fluidly coupled with and may extend generally tangential from the hub portion of the discharge assembly. The hub portion may define an annular volume fluidly coupled with the plurality of arms. The cooling system may also include a blower impeller disposed in the annular volume and coupled with the rotary shaft. The blower impeller may be configured to rotate with the rotary shaft and draw a cooling fluid into the discharge assembly.

    摘要： Apparatus and method for separating a fluid. The apparatus includes an inlet duct having an inlet flow entrance and an inlet flow exit, the inlet duct defining an inlet width that decreases between the inlet flow entrance and the inlet flow exit, and an inlet radius that increases between the inlet flow entrance and the inlet flow exit. The apparatus also includes a separating turn fluidly connected to the inlet flow exit of the inlet duct and including an outer surface defining an opening. The apparatus further includes a liquid outlet fluidly connected to the opening of the separating turn to allow a higher-density component of the flow to exit the separating turn, and an outlet duct having an outlet flow entrance connected to the separating turn, to allow a lower-density component of the flow to exit the separating turn.

    摘要： A fluid compression system is disclosed having a hermetically-sealed housing with at least a motor and a compressor arranged therein. The motor may drive both the compressor and a blower configured to circulate a cooling gas throughout the housing and thereby cool the motor and accompanying radial bearings. The cooling gas may be cooled in a gas-to-gas heat exchanger fluidly coupled to the blower and configured to receive a flow of process gas to cool the cooling gas. The process gas may be the suction process gas for the compressor, or the compressed process gas as discharged from the compressor.

    摘要： A fluid takeoff assembly for a motor-compressor is provided and includes an outer pipe having an inlet and an outlet, and an inner pipe defining a fluid passage extending from an open axial end toward a closed axial end thereof and a radial opening fluidly coupled with the fluid passage. The inner pipe may be disposed in the outer pipe such that the open axial end and the closed axial end are oriented toward the outlet and the inlet, respectively, and the inner and outer pipes define an annular space therebetween. A cross-flow member may be coupled with the inner pipe and may define a flowpath fluidly coupled with the fluid passage via the radial opening. A vane and the cross-flow member may be disposed in the annular space and configured to at least partially induce a swirling flow in a process fluid flowing through the annular space.
