Definitions

  • Another purpose of the present invention is to disclose a high performance liquid ring compressor which allows to obtain working pressure values as high as ten times the value of the atmospheric pressure.
  • a further purpose of the invention is to provide a liquid ring compressor, wherein the technical characteristics are higher than those of the traditional liquid ring compressors.
  • Said tapering used in rotors of liquid ring machines having a gas distribution through a central stator with a frusto conical shape, allows to obtain higher performances than in the known art at working pressures of about 300-400 KPa.
  • the blades 14 are radial and curved towards the periphery of the rotor 12A, 12B and are one another equally spaced in order to allow the passage of the same amount of gas.
