Generating a Vacuum

Using a power connection or compressed air connection, it is possible to generate a vacuum. A distinction is made between electrical and pneumatic vacuum generation.

Electrical Vacuum Generation

If there is no compressed air connection, you can also generate a vacuum using a pump or a blower. When selecting a suitable vacuum generator, you should first consider whether you need a high vacuum level or a high suction rate. Vacuum blowers are characterized by a very high suction rate, for example. As a result, they are particularly suited to handling processes in which air-permeable workpieces such as particle boards or cardboard boxes are to be handled. For lifting operations that require a high vacuum level, we recommend vacuum pumps. Vacuum pumps are therefore often used in vacuum handling systems. Vacuum pumps are available in various designs: In addition to dry-running pumps and oil-lubricated pumps, there are also water-ring pumps that are particularly suitable for use in the food industry.

Pneumatic Vacuum Generators

A so-called ejector can be used to generate a vacuum pneumatically. Ejectors generate vacuum according to the so-called Venturi principle, in which compressed air is passed through a Venturi nozzle. The air is first compressed and then expands again, creating the necessary vacuum. Due to their low weight and compact design, ejectors can be installed directly on the gripping system or the robot. Ejectors are available in single-stage and multi-stage versions. In multi-stage ejectors, several nozzles are connected in series. Multi-stage ejectors have a higher suction capacity than a single-stage ejector.
