Multiphase Dry Vacuum Pump Fuel Way


CZPT dry vacuum pump Gasoline Way


  • Airflow course radial, Corrosive process fuel does not assault the bearing and equipment axially direct
  • Airflow path axial, Corrosive method assault the bearing and gear axially in gear cap violent
  • Approach gas is compressed uniformly in every single phase of rotors. Uniform compression warmth, so decrease exhaust fuel temperature
  • The approach gas is compressed centrally at the stop of screw, so substantial exhaust gas temperature and screw
  • Approach gasoline could speak to with much more cooling jacket floor, higher heat dissipation effectiveness
  • Process gasoline could get in touch with with number of cooling jacket area, low warmth dissipation
  • Roots rotor is far more resistant to particles and adherents, couple of impacts on its overall performance soon after its area dress in and corrosion
  • CZPT rotor is unsuitable for particles and adherents, large impacts on its functionality soon after its surface wear and corrosion
