Liquid ring compressor

Abstract

Liquid ring compressor, characterized by an eccentric inner rotor ( 6 ) is supported in axles ( 8, 9 ) to an outer co-rotor ( 3 ) for the liquid ring, where the bearing of the co-rotors ( 11 ) is outside the same axles on each side is enclosed in an enclousure where it on each sides of the bearing ( 11 ) is arranged a rotating lip seal ( 82 ) which lip ( 83 ) abut the axles ( 8, 9 ) at low speed, and which at high speed is projected due to centrifugal forces out and lifts itself from the axles, where through holes ( 81 ) through the co-rotor's sidewalls and bearing enclosure, its volume within the liquid ring is aired to the surrounding enclosure ( 1 ), and ensures that it is not created a differential pressure across the bearings and the seals of the bearings.

1 . Liquid ring compressor, characterized by an eccentric inner rotor ( 6 ) is supported in axles ( 8 ,  9 ) to an outer co-rotor ( 3 ) for the liquid ring, where the bearing of the co-rotors ( 11 ) is outside the same axles on each side is enclosed in an enclosure where it on each sides of the bearing ( 11 ) is arranged a rotating lip seal ( 82 ) which lip ( 83 ) abut the axles ( 8 ,  9 ) at low speed, and which at high speed is projected due to centrifugal forces out and lifts itself from the axles, where through holes ( 81 ) through the co-rotor's sidewalls and bearing enclosure, its volume within the liquid ring is aired to the surrounding enclosure ( 1 ), and ensures that it is not created a differential pressure across the bearings and the seals of the bearings.  
   
   
       2 . Compressor according to  claim 1 , characterized by that the rotor ( 6 ) in the periphery has a number of cells ( 61 ) with half cylindrical shape where the arc is turned towards the centre.  
   
   
       3 . Compressor according to  claim 1 , characterized by the cells ( 61 ) of the rotor ( 6 ) has radial canal openings ( 62 ) on each side surrounded of a circular smooth section ( 63 ) for sealing against a stationary commutator ( 7 ) placed in the centre of the rotor.  
   
   
       4 . Compressor according to  claim 1 , characterized by that it from hole ( 75 ) in the commutator ( 7 ) in the compression sector is injected liquid where liquid beams crush of the rims of the canal opening ( 62 ) to the cells ( 61 ) of the rotor.  
   
   
       5 . Compressor according to  claim 1 , characterized by that the commutator ( 7 ) on each side has peripheral grooves ( 71 ), where injection liquid exist under pressure and inhibit gas leaks.  
   
   
       6 . Compressor according to  claim 1 , characterized by that the periphery of the commutator ( 7 ) is outside the co-rotors bearing seals so that leaking water from the gap between the commutator and the rotor is projected out in the liquid ring without passing the bearing seals.  
   
   
       7 . Compressor according to  claim 1 , characterized by that the bearings ( 11 ) for the co-rotor are of ball or roller bearings types.  
   
   
       8 . Compressor according to  claim 1 , characterized by that bearings ( 11 ) are slide bearings, including hydrodynamic types.  
   
   
       9 . Use of a compressor according to  claim 1  as an air compressor and water compatible gasses where water is used as injection liquid.  
   
   
       10 . Use of a compressor according to  claim 1  as a compressor in a gas turbine plant.
