CZPT Multiphase Dry Vacuum Pump structure benefit

Multiphase Dry Vacuum Pump Gas Way


Screw dry vacuum pump Gas Way


  • Airflow direction radial, Corrosive approach gasoline does not attack the bearing and equipment axially immediate
  • Airflow direction axial, Corrosive procedure attack the bearing and gear axially in gear cap violent
  • Procedure gasoline is compressed uniformly in every stage of rotors. Uniform compression warmth, so lower exhaust fuel temperature
  • The process gasoline is compressed centrally at the stop of screw, so high exhaust gasoline temperature and screw
  • Method gasoline could make contact with with much more cooling jacket surface, substantial warmth dissipation effectiveness
  • Method gas could speak to with few cooling jacket area, reduced warmth dissipation
  • Roots rotor is a lot more resistant to particles and adherents, number of impacts on its performance after its surface wear and corrosion
  • Screw rotor is unsuitable for particles and adherents, massive impacts on its performance following its surface area put on and corrosion
