Basic ejector »SBP-C« Bleeder valve, Silencer, Nozzle size 1.5 mm - Riegler 108394

Basic ejector »SBP-C«, Bleeder valve elec. vacuum switch, Silencer, Nozzle size 1.5 mm, Compressed air / vacuum connection 6/8 mm Purely pneumatic vacuum generator that operates on the Venturi principle. Compressed air enters the ejector at A and flows through the nozzle B. This results in a vacuum immediately behind the nozzle outlet, and air is drawn in through the vacuum inlet D. This air and the driving air leave the ejector via the silencer C. Properties: Vacuum generator with a single nozzle, available in six power ratings, with a high maximum vacuum value (85%)Connection of compressed air and vacuum with push-in couplingBasic housing with connection facility for a vacuum switchMaximum suction capacity with minimum compressed air consumptionMinimum size, low weightVarious power ratings for optimised air consumption Applications: For universal use in handling systems with very high dynamic movementsHandling all kinds of air-tight componentsFor use in separation systems where space is restrictedConstruction of ejector blocks for centralised or decentralised individual control of suction pads

About Vacuum ejectors

Vacuum ejectors generate negative pressure right at the gripping point by driving compressed air through a nozzle on the Venturi principle. No separate vacuum pump is needed, the existing air network does the work at an operating pressure of 4.5 to 6 bar. The group runs from the small basic ejector to the compact ejector with vacuum switch and air saving control.

What matters when choosing

• Nozzle size is the first criterion. Together with the maximum suction rate it decides how quickly the workpiece is held.
• Air consumption during suction drives the running cost. It weighs more heavily on long holding times than on short cycles.
• Connection: push in connector, plug connection or threaded connection. Plug versions are quicker to fit, threaded ports suit fixed pipework.
• Operating pressure: versions are rated for a maximum of 4.5 to 6 bar and some call for at least 5 bar. Line pressure has to match the design point of the nozzle.
• Size: length ranges from 35 to 228 mm. For mounting directly on the gripper, width, height and a fitted silencer count alongside length and weight.

Typical applications

• Handling sheet metal and panels with vacuum cups
• Labelling and packaging machines with short cycle times
• Pick and place and part feeding in electronics production
• Workholding on vacuum tables at machining centres
• Local vacuum generation at the machine instead of a central pump

Depending on version the housings are made of plastic, of impact resistant plastic or of anodised aluminium. Production takes place in Germany and China.
