Résumé : |
By using a vacuum, powder or granular materials can be transported without any problems. Depending on the application, different vacuum pumps for pneumatic suction conveying can be considered. The decisive factors here include the length of the conveying distance, the type of conveying and the required differential pressures. |
Note de contenu : |
- Different principles of vacuum generation
- Side channel blowers for short conveying distances
- Rotary lobe blowers for high volume flows
- Only rotary vane vacuum pumps achieve a vacuum of 99.99 %
- The classic : Mink claw vacuum pumps
- Fig. 1 : Different conveying methods require different differential pressures or vacuum levels
- Fig. 2 : Vacuum levels (ultimate pressures) of the various blowers and vacuum pumps
- Fig. 3 : Rotary lobe blowers with and without acoustic enclosure operate contact-free and thus without oil in the compression chamber |
