摘要:
A fluid processing machine that includes a stator capable of generating an electromagnetic field and a first rotor section having at least one impeller and at least one permanent magnet. The stator is configured to electromagnetically engage with the first rotor section so as to rotate the first rotor section about a central axis in a first rotational direction. Further rotor sections can also be included that are induced to rotate in the first rotational direction. Other rotator sections with impellers and permanent magnets can also be included that are driven in a second, contra-rotating, direction by a second stator. Several of the fluid processing machine can be distributed within a surface system or subsea system that transports produced fluid from wells to a surface facility.

System and methods are configured to adjust fluid pressure within a barrier fluid system (200) on a subsea fluid processing machine. More specifically, a barrier fluid pressure system (200) is located at the subsea location and includes a barrier fluid pressure regulator module (210) having one input communicating or being pressure matched with a process fluid flowline (230) and a second input communicating with the barrier fluid pressure system. The pressure regulator module (210) is configured to locally adjust the barrier fluid pressure (P BF ) depending upon the fluid process pressure (P process ).
摘要:
A technique facilitates movement of fluids with reduced component loading by utilizing opposed axial forces. The system for moving fluid may be in the form of a gas compressor, liquid pump, or other device able to pump or otherwise move fluid from one location to another. According to an embodiment, the system comprises rotor sections which are combined with pumping features. The rotor sections are disposed radially between corresponding inner and outer stator sections which may be powered to cause relative rotation of inner and outer rotor sections in opposite directions. The rotors and corresponding pumping features are configured to move fluid in opposed axial directions toward an outlet section so as to balance axial forces and thus reduce component loading, e.g. thrust bearing loading.
摘要:
A fluid processing machine (36) that operates on a process fluid (44) includes a frame (54) that structurally supports at least a portion of the fluid processing machine (36) and a shaft (42) that operatively rotates about an axis (66) and relative to the frame (54). The shaft (42) includes a projection (62) in a radial direction relative to the axis (66) that is operationally contacted by a sealing armature (64) that has an axial degree of freedom relative to the axis (66). Additionally, the fluid processing machine (36) includes a dynamic rotational seal (72) between the projection (62) and the sealing armature (64) and a dynamic axial seal (78) between the sealing armature (64) and the frame (54). The dynamic axial seal (78) includes one or more metallic seals (80) that seal between the sealing armature (64) and the frame (54) circumferentially about the axis (66).
