Correct question name error

| Jun 19, 2014 at 16:48 | comment | added | rob♦ | To calculate the pressure you'd need a lot more details about the internal structure. Probably it's better to seal the vacuum inlet with some quick-n-dirty lifting harness and just measure the weight you can support. | |
| Jun 19, 2014 at 14:41 | comment | added | Robert English | By measurement of the vacuum, I mean the amount of force behind the moving air. I'm looking for something like X Newtons/mm^2. This is so I can get an idea of the weight that this vacuum will be able to hold. | |
| Jun 19, 2014 at 13:59 | comment | added | rob♦ | You have a good description of the pump now in an answer. Can you clarify what you want to know about measurement of the vacuum? That's a broad subject, and doesn't really get interesting until vacuum pressures below what this sort of pump could achieve. | |

Emphasis on the main issue in question.

| Jun 19, 2014 at 7:18 | comment | added | Robert English | @Rams Double negative? Can you please clarify what you meant to say? | |

| Jun 18, 2014 at 16:56 | comment | added | Rams | I doubt that your understanding of the mechanism may not be correct. The pneumatic operation of the robot doesn`t mean vacuum only. The pressurized air must be moving the parts by pushing the piston or pulling the piston when the pressure is reversed. Just as a hydraulic jack works | |
| Jun 18, 2014 at 16:46 | comment | added | John Rennie | The vacuum is created by Bernoulli's principle. The high velocity of the air passing though the horizontal tube lowers the pressure in the side branch. I have never used a pump of this sort that worked with an air stream, but I've many times used this sort of pump that worked using a water stream. | |
| Jun 18, 2014 at 16:07 | comment | added | Robert English | My only certainty is that it looks like I have depicted it in my question above. I'm new to pneumatics and can make no presumtions. It does not look like the ball valve you've shown. | |
| Jun 18, 2014 at 15:56 | comment | added | Kyle Kanos | Are you sure it is a T-valve and not a 3-way ball valve? | |
| Jun 18, 2014 at 15:54 | comment | added | Robert English | Thanks for the reply. If this were true the mechanism I have would only show this internally. My mechanism has three openings of all the same size. | |
| Jun 18, 2014 at 15:49 | comment | added | nivag | Hopefully someone with more knowledge can provide a better answer but I suspect it is to do with relative diameters of the pipes requires a drop in pressure at the vacuum tube to maintain the correct flow through the device. | |
