    [Vacuum Suction] Relation between cup diameter and ejector flow rate?

    Mind me asking a different question this time, I was asking about the Ejector suction flow rate before. I would like to ask about compressed air flow rate right now. At the university I am in, they use pipes with 5mm internal diameter for the compressed air supply that connects to various...

    [Vacuum Suction] Relation between cup diameter and ejector flow rate?

    Oh wow, so what I am understanding is that to reduce leakage, I am not supposed to increase the circumference, but rather to reduce it. I am starting to understand that a single larger cup will have more leakage than a single smaller cup, even though the smaller cup has a smaller surface area...

    [Vacuum Suction] Relation between cup diameter and ejector flow rate?

    Hey there, thanks a lot for your reply. This is actually for a final year project, so yes, I did read about the theory behind them. I have seen my friends obtain a vacuum lifting device that can lift a 100kg in theory, and it was able to lift the gypsum blocks I am attempting to lift...

    [Vacuum Suction] Relation between cup diameter and ejector flow rate?

    Hello, I am trying to determine the vacuum ejector flow rate I need to carry a Gypsum block of 30kg. Based on my calculations for pressure and force, I was able to obtain a configuration of 4 suction cups, each one being 8cm in diameter. I am planning to use one vacuum ejector per cup. We have...
