CZPT Multistage Dry Vacuum Pump structure benefit

Multiphase Dry Vacuum Pump Fuel Way


Screw dry vacuum pump Gasoline Way


  • Airflow path radial, Corrosive process gas does not assault the bearing and gear axially immediate
  • Airflow path axial, Corrosive method assault the bearing and equipment axially in equipment cap violent
  • Process fuel is compressed uniformly in each and every phase of rotors. Uniform compression heat, so reduced exhaust gasoline temperature
  • The approach gasoline is compressed centrally at the stop of screw, so higher exhaust gasoline temperature and screw
  • Method fuel could contact with more cooling jacket floor, large heat dissipation performance
  • Approach gas could make contact with with number of cooling jacket surface, low heat dissipation
  • Roots rotor is far more resistant to particles and adherents, handful of impacts on its overall performance soon after its surface area wear and corrosion
  • Screw rotor is unsuitable for particles and adherents, massive impacts on its overall performance right after its floor put on and corrosion
