Multiphase Dry Vacuum Pump Fuel Way


Screw dry vacuum pump Gas Way


  • Airflow direction radial, Corrosive process gas does not attack the bearing and equipment axially immediate
  • Airflow path axial, Corrosive process assault the bearing and equipment axially in equipment cap violent
  • Approach gas is compressed uniformly in each and every stage of rotors. Uniform compression warmth, so reduce exhaust gas temperature
  • The procedure gasoline is compressed centrally at the finish of screw, so higher exhaust gasoline temperature and screw
  • Procedure gasoline could contact with a lot more cooling jacket area, higher heat dissipation performance
  • Method gasoline could contact with number of cooling jacket surface, low warmth dissipation
  • Roots rotor is much more resistant to particles and adherents, few impacts on its efficiency after its surface area use and corrosion
  • Screw rotor is unsuitable for particles and adherents, big impacts on its functionality right after its surface dress in and corrosion
