摘要： Disclosed is a snubber bearing assembly for protecting a rotor and accompanying bearings from radial and axial rotor transient overload events. The bearing assembly includes a snubber journal mounted on the rotor and a snubber housing having a radial snubber bearing mounted on its inside surface, the radial snubber bearing being radially-offset from an outer radial surface of the snubber journal. Lubricating plugs are disposed within a plurality of holes defined in the radial snubber bearing, the lubricating plugs being configured to provide lubrication between the radial contact surface and the outer radial surface during a radial rotor transient overload event. The snubber housing can also include opposing axial snubber bearings that have lubricating plugs disposed within holes defined therein also. The opposing axial snubber bearings are configured to be axially-offset from inner axial surfaces defined by the rotor journal and provide lubrication therebetween during an axial rotor transient overload event.

摘要： A cooling system for a rotating machine, such as a centrifugal compressor. Specifically, the cooling system may be configured to cool radial and axial magnetic bearings in the rotating machine and the bearing control system that controls said bearings. The cooling system includes canned magnetic radial bearings on each end of the rotor and a canned bearing control system. The canned bearings and canned bearing control system may be filled with a dielectric cooling fluid and in fluid communication with each other via sealed conduits. Accordingly, the radial magnetic bearings and the bearing control system may be entirely immersed in the dielectric cooling fluid to regulate heat generation. An axial magnetic bearing may also be canned and fluidly coupled to the cooling system to immerse the axial magnetic bearing in the dielectric cooling fluid.

摘要： A diaphragm for a steam turbine is disclosed that has at least one arc of admission. The arc of admission has a plurality of nozzles arranged about the circumference of the diaphragm and are configured to eject a working fluid at succeeding rotor blades axially-spaced from the diaphragm. The flow area of the first few nozzle vanes in the arc of admission is gradually increased along the arcuate length of the diaphragm, thereby mitigating the load impulse absorbed by each rotor blade as it enters the arc of admission. The flow area of the last few nozzle vanes in the arc of admission is gradually decreased so that each rotor blade does not suddenly go from full load impulse to zero and thereby contribute to the fatigue of the rotor blade and create unwanted noise.
