Over the last two weeks I’ve trained a number of our distributors on EXAIR products. We’ve discussed the benefits of engineered compressed air products, the way these products can impact a company’s bottom line, and how they work.
One of the topics which is sure to produce good conversation is our vacuum generator product line, the E-Vacs. Using a compressed air powered venturi to produce vacuum, the E-Vac is attractive for a number of applications because the vacuum flow is instantaneous. This means we can produce vacuum only when and where it is needed rather than keeping a vacuum pump in continuous operation.
This instantaneous nature of the E-Vac was recently attractive to an end user in need of a better method to handle electronic power supplies used in their computer production process. They wanted the lifting and placement of the power supplies to be semi-automated, with an operator turning the lifting system on and off.
This type of application is perfect for an E-Vac. In order to determine the best solution, for this or any E-Vac application, we have to first determine the following:
- Is the material/item to be lifted porous or non-porous?
- Porous materials will have leakage through the material itself, or through inconsistencies in the material surface. Items such as cardboard, fabrics, or a golf ball are considered porous.
- Non-porous materials will not have leakage through the material. Items such as smooth glass and flat plastics are considered non-porous.
- What is the weight of the item to be lifted?
- How will the item be lifted?
- Will the vacuum cups mount to the top of the workpiece to the side? This will determine if the suction cups will be in a horizontal or vertical plane when lifting the product.
Using this information we can determine the proper safety factor to apply (2 for horizontal orientation of the vacuum cups, 4 for vertical orientation), and the potential vacuum cups to be used. Then, based on size of the workpiece and space constraints we can select the proper vacuum cups. And finally, using charts on file with the EXAIR Application Engineering department, we can select the correct E-Vac or E-Vacs for the application.
If you have a pick-and-place need in your facility, contact an EXAIR Application Engineer. We’ll be happy to help choose the right components for your setup.
