What influence does the vacuum and pressure supply tube with its connectors have on the overall vacuum system?
• The size of the pressure supply tube must fit the air consumption of the vacuum generator. • The size of the vacuum tube must fit the suction cup being used. • The distributor must be selected to fit the tube and the number of suction cups which have been chosen. • The size of the vacuum tube must fit the vacuum generator being used. • Long, slim tubes very often form a bottleneck and reduce the efficiency of the vacuum generator. The result of this is a higher input (air consumption of the vacuum generator), but a lower output (increased evacuation time). Formula for nominal diameter (mm) P1 connection (1) ≥ 2 x ≥ Ø Venturi nozzle V connection (2) ≥ 3 x ≥ Ø Venturi nozzle = high vacuum V connection (2) ≥ 4 x ≥ Ø Venturi nozzle = High suction capacity Gültig für Schlauchlänge <= 0.5 m For tubing lengths of > 0.5 m select a larger diameter.
