6.2 Suction of the Workpiece (Vacuum Generation)
The ejector is designed for vacuum handling of workpieces in combination with suction systems. The vac-
uum is generated in a nozzle according to the Venturi principle, using suction generated by the flow of
accelerated compressed air. Compressed air is channeled into the ejector and flows through the nozzle. A
vacuum is generated immediately downstream of the motive nozzle; this causes the air to be sucked
through the vacuum connection. The air and compressed air that have been removed by the suction exit
together via the silencer.
The venturi nozzle on the ejector is activated and deactivated using the suction command:
•
In the NO (normally open) variant, the venturi nozzle is deactivated when the suction signal is re-
ceived.
•
In the NC (normally closed) variant, the venturi nozzle is activated when the suction signal is re-
ceived.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum value is
shown on the display.
The diagram below shows the vacuum curve for when the air saving function is activated:
