Multiphase Dry Vacuum Pump Gas Way


Screw dry vacuum pump Gas Way


  • Airflow course radial, Corrosive procedure fuel does not assault the bearing and equipment axially direct
  • Airflow direction axial, Corrosive process assault the bearing and gear axially in equipment cap violent
  • Process fuel is compressed uniformly in every stage of rotors. Uniform compression heat, so reduce exhaust gasoline temperature
  • The procedure gas is compressed centrally at the end of screw, so higher exhaust fuel temperature and screw
  • Method gasoline could make contact with with a lot more cooling jacket floor, substantial heat dissipation performance
  • Process fuel could make contact with with few cooling jacket surface area, low heat dissipation
  • Roots rotor is far more resistant to particles and adherents, handful of impacts on its performance right after its surface wear and corrosion
  • Screw rotor is unsuitable for particles and adherents, large impacts on its performance after its surface put on and corrosion
