Abstract: A magnetic bearing is disclosed that includes a sensing wire wrapped around one or more of the bearing coils and configured to measure the resistance to ground of each bearing coil. With the presence of contaminants such as liquids, a protective coating disposed about the bearing coils degrades over time, thereby reducing the resistance to ground of the bearing coils. The sensing wire transmits the detected resistance to ground of the bearing coils to an adjacent sensing device, which can provide an output that informs a user whether corrective action is required to prevent damage or failure of the magnetic bearing.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A compressor is disclosed having a shaft seal assembly and system that allows a high-pressure compressor to settle-out at a lower pressure level during shutdown. The seal assembly may be disposed about a portion of the shaft and define a blow-down seal chamber, the seal assembly including one or more gas seals in fluid communication with the blow-down seal chamber. A blow-down line is communicably coupled to the blow-down seal chamber to reference the blow-down seal chamber to a low pressure reference, such as a separate centrifugal compressor, or the like. Referencing the blow-down seal chamber to the low pressure reference reduces the required sealing pressure of the one or more gas seals. A valve may be disposed in the blow-down line and configured to regulate a flow of process gas leakage through the blow-down line.
