CZPT Multiphase Dry Vacuum Pump structure benefit

Multiphase Dry Vacuum Pump Fuel Way


Screw dry vacuum pump Gasoline Way


  • Airflow direction radial, Corrosive process gasoline does not attack the bearing and gear axially immediate
  • Airflow path axial, Corrosive procedure attack the bearing and equipment axially in gear cap violent
  • Procedure gas is compressed uniformly in each phase of rotors. Uniform compression warmth, so reduced exhaust gas temperature
  • The approach gas is compressed centrally at the stop of screw, so higher exhaust gas temperature and screw
  • Method fuel could get in touch with with more cooling jacket area, higher heat dissipation effectiveness
  • Method fuel could contact with few cooling jacket surface area, reduced heat dissipation
  • Roots rotor is more resistant to particles and adherents, few impacts on its efficiency after its surface wear and corrosion
  • Screw rotor is unsuitable for particles and adherents, large impacts on its overall performance soon after its surface dress in and corrosion
