Definitions

  • the magnets are placed in recesses on the impeller face and the control disc.
  • the depressions can be designed as axially continuous openings or blind hole-like recesses.
  • the magnets can be fixed by a hardening mass that withstands the gases and liquids during operation.
  • the arrangement of the magnetic poles must be chosen so that Locking torque-like "torque profiles of the impeller must be avoided.
  • the force ratios must be such that the magnetic forces are greater than or equal to the sum of the axially parallel hydrodynamic forces during operation of the liquid ring compressor in the direction of the control disk.
  • This embodiment of the invention is particularly manufacturing technology easy to manufacture and avoids just like the one above described solution a touch of the impeller face and Control disc.
