摘要： A unique low cost and efficient submersible, hermetically sealed, variable speed system intended to drive submersible boosting units. The system includes a unique combination of a liquid filled electrical motor connected to a hydraulic coupling and a magnetic coupling driver section, in a hermetically sealed container, with a magnetic coupling follower driving a booster unit. The system further includes integrated cooling, lubrication and control functionality. The drive unit has an actuating system connected to internal guide vanes which controls the liquid flow between the pump impeller and turbine wheel of the hydrodynamic coupling and hence the torque and speed. The combined system is a sealed seal-less and topside-less submersible drive unit that can operate in harsh subsea environments. The drive unit opens up for use of thin walled pressure casings and low pressure electrical penetrators.

摘要： The invention provides a magnetic coupling assembly (1), comprising: a rotatable male coupling member (2) comprising magnets (3); a rotatable female coupling member (4) comprising magnets (5); a static separation member (6) arranged between the male and female coupling members, a first channel (7) in a gap between the male coupling member and the separation member, a second channel (8) in a gap between the female coupling member and the separation member, an axial internal channel (9) in the male coupling member, a magnetic coupling section (10) of the static separation member, wherein said magnetic coupling section is the section of the static separation member between the magnets of the male coupling member and the magnets of the female coupling member, wherein the female and male coupling members are rotatable coupled by the magnets through the magnetic coupling section of the static separation member. The magnetic coupling assembly is distinguished in that: the first channel, the second channel and the axial internal channel contains fluid (11) forced to flow through said channels for cooling and rotodynamic stabilization, and the magnetic coupling section of the static separation member has a length to diameter ratio larger than one.
