Multistage Dry Vacuum Pump Gas Way


CZPT dry vacuum pump Gasoline Way


  • Airflow path radial, Corrosive procedure gasoline does not attack the bearing and equipment axially direct
  • Airflow direction axial, Corrosive process assault the bearing and equipment axially in equipment cap violent
  • Method fuel is compressed uniformly in each stage of rotors. Uniform compression warmth, so lower exhaust gasoline temperature
  • The process fuel is compressed centrally at the stop of screw, so higher exhaust fuel temperature and screw
  • Method gas could contact with far more cooling jacket area, large heat dissipation performance
  • Procedure gas could get in touch with with handful of cooling jacket floor, lower heat dissipation
  • Roots rotor is more resistant to particles and adherents, handful of impacts on its overall performance right after its floor put on and corrosion
  • CZPT rotor is unsuitable for particles and adherents, large impacts on its performance after its floor wear and corrosion
