The auxiliary bearing receiver housing may include an axial inner surface, a first radially extending surface, and a first arcuate surface extending therebetween. The inertia ring may include an axial outer surface, a second radially extending surface, and a second arcuate surface extending therebetween. The second arcuate surface may have a radial outer end adjacent the second radially extending surface and a radial inner end adjacent the axial outer surface. The inertia ring may define a first angle between the axis of rotation of the shaft and a first tangent at a first point on the second arcuate surface adjacent the radial outer end, and a second angle between the axis of rotation of the shaft and a second tangent at a second point on the second arcuate surface adjacent the radial inner end. | 10-30-2014 |
20140360189 | INTEGRATED SEPARATOR TURBINE - A fluid processing system and method are provided for separating a liquid portion from a multiphase fluid. The system and method may include a steam turbine assembly coupled with a rotary shaft, and a separator coupled with the rotary shaft and positioned upstream of the steam turbine assembly. The separator may include an inlet end configured to receive a multiphase fluid, an outlet end fluidly coupled with the steam turbine assembly, and a separation chamber extending from the inlet end to the outlet end. The separation chamber may be configured to separate a liquid portion from the multiphase fluid to thereby provide a substantially gaseous fluid to the steam turbine assembly. | 12-11-2014 |
20150061432 | INTERFACE FOR THE TRANSMISSION OF ELECTRICAL POWER TO A MOTOR-COMPRESSOR - An interface for transmitting electrical power to a motor of a motor-compressor is provided. The interface may include a receptacle having a first end portion coupled with a stator of the motor and a second end portion defining a hole at least partially extending therethrough. The interface may also include a plug configured to be detachably coupled with the receptacle. The plug may include a rigid, conductive rod having a first end portion configured to be coupled with a penetrator of the motor-compressor, and a second end portion configured to be at least partially disposed in the hole of the receptacle and detachably coupled therewith. The rigid, conductive rod may be configured to electrically couple the penetrator with the receptacle, and the receptacle may be configured to transmit the electrical power to the stator. | 03-05-2015 |
20150064026 | MOTOR COOLING SYSTEM MANIFOLD - 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. | 03-05-2015 |
20150078880 | SUPPORT ASSEMBLY FOR A TURBOMACHINE - A support assembly and method for supporting an internal assembly in a casing of a turbomachine are provided. The support assembly may include a support member that may be slidably disposed in a recess formed in the internal assembly and configured to engage an inner surface of the casing. A biasing member may be disposed in a pocket extending radially inward from the recess. The biasing member may at least partially extend into the recess and may be configured to apply a biasing force to the support member disposed therein. | 03-19-2015 |
