    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.

    摘要: A compression system may include a compressor having first and second sides separated by a division wall, first and second shafts, and first and second radial bearings. The first and second shafts may be axially connected to each other at respective first ends via a rotor portion of an intermediate radial bearing. The rotor portion may include a plurality of laminations stacked between first and second plates fastened to each other. The first radial bearing may be disposed on a first side of the intermediate radial bearing and may be proximate a second end of the first shaft. The first radial bearing may be configured to support the first shaft. The second radial bearing may be disposed on a second side of the intermediate radial bearing and may be proximate a second end of the second shaft. The second radial bearing may be configured to support the second shaft.

    摘要: A turbomachine system and method, with the system including a slug detector coupled to a main line to detect a slug flow in a multiphase fluid in the main line. The system also includes a compressor fluidly coupled to the main line and disposed downstream of the slug detector, and a bypass line fluidly coupled to the main line upstream of the compressor and downstream of the compressor. The system further includes at least an upstream control valve fluidly coupled to the main line upstream of the compressor and communicably coupled to the slug detector. The upstream control valve is configured to actuate between a normal position, in which the upstream control valve directs fluid to the compressor, and a bypass position, in which the upstream control valve directs fluid to the bypass line, according to when the slug detector detects a slug flow.

    摘要: A seal assembly for a dual-flow compressor is provided. The seal assembly may include an annular body disposed about a rotary shaft between a first compression assembly and a second compression assembly of the dual-flow compressor. An inner radial surface of the annular body and an outer radial surface of the rotary shaft may at least partially define a radial clearance therebetween. The annular body may have a first seal section and a second seal section at a first axial end portion and a second axial end portion thereof, respectively. The first and second seal sections may at least partially define a cavity therebetween. The seal assembly may also include a reference line communicably coupling the cavity with an inlet of the first compression assembly and configured to at least partially generate a pressure differential between the cavity and an outlet of the first compression assembly.

    摘要: 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.
