9. A compressor unit for underwater operation, comprising:
a compressor and an electric motor, having
a housing with an inlet and an outlet for a pumping medium, and
a rotation axis around which a rotor rotates;
a cooling system that cools electromagnetic bearings of the compressor unit to an operating temperature,
wherein the cooling system provides a tap in an overflow of the compressor and a portion of the pumping medium is conveyed from the tap via pipelines through a filter, and then passed through two separate pipelines to the bearings,
wherein the rotation axis is aligned vertically during operation and the housing has a drain at an axial end located at the bottom.
10. The compressor unit as claimed in claim 9, wherein only interior surfaces of the compressor unit are constructed and arranged such that, when aligned vertically for operation, liquids located in the interior of the housing flow away due to the force of gravity and reach the drain.
11. The compressor unit as claimed in claim 10, wherein surfaces which continue from the drain are inclined in the interior of the compressor unit such that these wetting liquids flow away from the surfaces in the direction of the drain, when aligned vertically for operation.
12. The compressor unit as claimed in claim 11, wherein a condensation pump is connected to the drain and carries liquid away.
13. The compressor unit as claimed in claim 12, wherein the housing is mounted in a frame via supporting elements provided on the housing such that the housing is rotatable about a horizontal axis such that the drain changes from a low point to a high point.
14. The compressor unit as claimed in claim 12, wherein the horizontal axis around which the housing rotates runs in the area of the rotor center of gravity.
15. A method of assembly for an underwater compressor unit, having a compressor and an electric motor, the compressor unit having a housing with an inlet and an outlet for a pumping medium, and a rotation axis around which a rotor rotates, a cooling system that cools electromagnetic bearings of the compressor unit to an operating temperature, comprising:
filling the compressor unit with an incompressible fluid while the unit is above water;
transported the unit to an operating location under water;
connecting connections to the inlet and to the outlet of the unit; and
pumping the fluid out of the compressor unit through the drain,
wherein the cooling system provides a tap in an overflow of the compressor and a portion of the pumping medium is conveyed from the tap via pipelines through a filter, and then passed through two separate pipelines to the bearings,
wherein the rotation axis is aligned vertically during operation and the housing has a drain at an axial end located at the bottom.
16. The method as claimed in claim 15, wherein the fluid is distilled or demineralized water.
17. The method as claimed in claim 15, wherein only interior surfaces of the compressor unit are constructed and arranged such that, when aligned vertically for operation, liquids located in the interior of the housing flow away due to the force of gravity and reach the drain.
18. The method as claimed in claim 17, wherein surfaces which continue from the drain are inclined in the interior of the compressor unit such that these wetting liquids flow away from the surfaces in the direction of the drain, when aligned vertically for operation.
19. The method as claimed in claim 18, wherein a condensation pump is connected to the drain and carries liquid away.
20. The method as claimed in claim 19, wherein the housing is mounted in a frame via supporting elements provided on the housing such that the housing is rotatable about a horizontal axis and such that the drain changes from a low point to a high point.
21. The method as claimed in claim 19, wherein the horizontal axis around which the housing rotates is arranged in an area of the rotor center of gravity.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A disk loading apparatus adapted to hold a disk inserted through an insertion slot between a flap rotatable in a seesaw manner and a roller formed in an approximately drum-like shape and to carry said disk to a turntable by the rotation of said roller while performing centering,
said apparatus having a disk stopper positioned at the back of said turntable and being arranged in such a manner that when said disk is fitted between bosses provided at the respective left and right ends of said disk stopper, the center hole of said disk is positioned over said turntable, wherein
there is provided an anti-sinking rib protruding from the outer peripheral surface in the lower end portion of said each boss toward said insertion slot, said anti-sinking rib being adapted to receive said disk and having a slope inclined downward toward said insertion slot, said slope being adapted to scoop the leading end of said disk up to bring said disk into contact with the outer peripheral surface of said each boss.
2. A disk loading apparatus adapted to hold a disk inserted through an insertion slot between a flap and a roller and to carry said disk by the rotation of said roller,
said apparatus having a disk stopper and being arranged in such a manner that when said disk is fitted between bosses provided at the respective left and right ends of said disk stopper, the center hole of said disk is positioned over a turntable, wherein
there is provided an anti-sinking rib protruding from the lower end portion of said each boss toward said insertion slot, said anti-sinking rib being adapted to receive said disk.
3. The disk loading apparatus according to claim 2, wherein said anti-sinking rib has a slope inclined downward toward said insertion slot, said slope being adapted to scoop the leading end of said disk up to bring said disk into contact with said each boss.
