Multistage Dry Vacuum Pump Gasoline Way


Screw dry vacuum pump Gas Way


  • Airflow route radial, Corrosive approach gas does not attack the bearing and gear axially direct
  • Airflow path axial, Corrosive process attack the bearing and equipment axially in equipment cap violent
  • Procedure fuel is compressed uniformly in every single phase of rotors. Uniform compression heat, so decrease exhaust gasoline temperature
  • The approach gasoline is compressed centrally at the end of screw, so higher exhaust fuel temperature and screw
  • Procedure gasoline could speak to with a lot more cooling jacket area, substantial heat dissipation effectiveness
  • Approach gasoline could get in touch with with number of cooling jacket surface area, lower heat dissipation
  • Roots rotor is a lot more resistant to particles and adherents, number of impacts on its performance right after its surface use and corrosion
  • Screw rotor is unsuitable for particles and adherents, massive impacts on its efficiency soon after its floor dress in and corrosion
