Abstract
The invention includes a compressor unit with a connected drive by a high-frequency motor for compressing gases and which is suitable for great ocean depths and for natural gas conveyance from the ocean floor where the low temperature obtaining in the water is effectively utilized. The compressor unit is supported by magnetic bearings in a housing. The compressor includes a plurality of compressor stages connected by pipe lines which form a surface cooler on the suction side arranged around the housing.
Claims15
A compressor comprising a housing having surfaces in contact with sea water, an electric drive motor in said housing, a shaft connected to said electric drive motor and extending on at least one side of said drive motor through said drive motor housing, a compressor arranged in said housing with said drive motor and having means defining at least one compressor stage on at least one side of said drive motor, an axial suction inlet for said compressor on one end of said housing and a radially pressure discharge connected to said stages, magnetic bearings supporting said shaft adjacent to said drive motor on each end thereof and a cooling coil connected to said compressor at said at least one stage and encircling said housing;
- said coil having surfaces for heat transfer with the sea water.
A compressor arrangement, comprising:
- a housing having an outer surface in contact with sea water;
- a high frequency motor positioned in said housing;
- a compressor shaft connected to said high frequency motor and extending through said high frequency motor and extending from said high frequency motor on at least one side;
- a compressor arranged in said housing with said drive motor and including a plurality of compressor stages connected to said shaft, said compressor stages having flow channels positioned adjacent said housing for heat transfer with said sea water;
- a plurality of magnetic oil free bearings supporting said shaft;
- and, surface cooler means including a cooling pipeline connected between stages of said plurality of stages, said cooling pipeline extending around and spaced away from said housing and having an outer surface in contact with the sea water for transfer of heat from gas passing between compressor stages of said plurality of compressor stages and the sea water.
