Re: pnneumatic axe robots

hey alex when u come round to mine i'll talk to u about pneumatics and what u need and where to get them.

Re: pnneumatic axe robots

Ok, although I have found neally all of the parts I need...

Re: pnneumatic axe robots

also i was wondering what co2 tank, fits directly to the Trevor reg?as I think that would be a better option than a paint ball tank with an adapter.

Re: pnneumatic axe robots

Just wondering about quick exhaust valves, from what I have picked up, is that you put gass though one port, and it goes out of another (in to the ram) but when the pressure in the first port drops below the second one, it vents it, so the air doesnt have to travel all the way back though the solenoid valve? I was just wondering, as it may increase the flow rate on my axe, if I fit it on both ports on the ram...

Re: pnneumatic axe robots

Look at Woodies site. Everything you need for such things is there.

And yes, even with the conventional use of QEV's the ram will work faster than without them.

Re: pnneumatic axe robots

Whats the conventional use of them?

[maddox10]

Re: pnneumatic axe robots

Woody uses those as piloted (air steered) 3/2 valves with high flow capacity, to get the pressured gas in the ram at high rate. In the Industry, conventional use of the QEV is to get the gas out at a high rate. As the restriction we have in our robots ain't there.
Valves are big enough for the desired flowrate.

Re: pnneumatic axe robots

So are you saying, that if I use a decent solenoid valve, useing one won't make a difference?

[maddox10]

Re: pnneumatic axe robots

Large enough, then it won't make a difference, but a 1/4bsp foot QEV is the equivalent of a 1/2 bsp solenoid valve.

I know what is lighter, cheaper and smaller.

Re: pnneumatic axe robots

Im looking for a regulator, and don't think Trevor makes them any more, so i was wondering if i could use a paint-ball one? i cant find any co2 ones, but would an air regulator do, or just freeze up? this is an example of what im talking about but it has the wrong fittings, so i would probably use a different one. http://www.ebay.com/itm/NEW-PAINTBALL-C ... 3321wt_968

sorry to re open the old thread, but it is quiet relevant to it.

Re: pnneumatic axe robots

In theory it should work.

And there ain't no wrong fitting there. It just ain't ment for an industrial CO2 bottle, but for paintball use.

We, Team RCC, use standard paintball bottles. Lighter, smaller and easier to buy. We have our own filling rig, and at events we use that , meaning we can refill our bottles as anybody else.

Re: pnneumatic axe robots

ok thanks, I was going to use paint-ball bottles, but I cant find the correct fitting to transfer from the paint-ball pin-valves to a BSPT or BSP type joint http://www.technobotsonline.com/pneumat ... -stud.html
I don't think i can by a straight conversion, but i cant even find a pin-valve part that I could use. any one know where i can get one? or will I have to butcher a filling station? :P

Re: pnneumatic axe robots

I guess it's possible to adapt such a regulator with any exit connector. This one is just ment as plug and play between bottle and marker. We're not that restricted.

Also, pin valves need an external on/off valve to adhere to the rules. Easier and lighter to replace the pinvalve immediatly with an on/off valve

Re: pnneumatic axe robots

we were going to replace the valve on the bottle with this http://www.ebay.com/itm/NEW-PAINTBALL-C ... 2255wt_968
but the valve screws in to the reg, but I think the regulator has a pin-valve out put, or the tread off a pin-valve and i need to find a fitting to go between the regulator and the rest of the co2 fittings.

Re: pnneumatic axe robots

The regulator replaces the pin valve.

The thread out of the regulator is CGA320 which is so close to 1/2 BSP that it doesnt matter.

I would use this stud and then have a reducing straight to reduce from 12mm to 8mm
