Re: PMEUMATICS

Just wondering would 150psi and 1meter of pipe and a cylinder of 16mm bore and 54mm stroke and no buffer tank be able to 'flip' a robot IN THE AIR?

Re: PMEUMATICS

How's your math?

So .... Lets take your cylinder 16mm bore and 54mm stroke @ 10 bar.

Force = .008 x 16 x 16 x 10 = 20.48 kgf

So you could potentially move a mass of 20.48 kg's a distance of 54mm OR

1/2 the mass twice the distance.... 10.24 Kg's a distance of 108mm.

You could possibly self right yourself or turn someone over with such a low force
NO AIR TIME.

NOTE:-
If your flipper tip lift to cylinder stroke ratio is 2 .... i.e. 108mm of flipper tip movement ...then you'll only be able to lift 10.24 kg's.

What you need is to maximise these two equations.

Energy = Pressure x Volume
AND
Power = Energy / Time

OR as much pressure as possible/practical in the biggest cylinder possible/practical and this ENERGY applied / delivered in the shortest possible time.

The time part of the equation is gas supply or flow dependant ...

Re: PMEUMATICS

Ok then thank for the help
and I am the best in my school in maths! No joke!

Proberly get it up and running(some events and prob a buffer tank if got space in robot) then update parts in about a year or later or sooner! To 750 psi :shock:

on the plus got my cylinder on it's way!!!!!!!

does this:

just wondering because the valve is G1/4 and the stud is bsp1/4?

Re: PMEUMATICS

it'd be easier to buy a valve with the coil. like this:
http://cgi.ebay.co.uk/5-port-solenoid-v ... 500wt_1156

this valve would work if you are going to be running of 24v. or you could buy one new from:
http://cgi.ebay.co.uk/Pneumatic-Solenoi ... 797wt_1141

i bought a 24v 3/8 valve from this seller. all seems good.

Re: PMEUMATICS

First one comes with a 24v coil (me 14v( can a 12v coil work with 14v?) and second one maybe

[jonny]

Re: PMEUMATICS

yes you can use a 12v on 14v. the second one should be fine. after you,ve bought just send them a message saying you want the 12v version.

Re: PMEUMATICS

Ok thanks get that done soon !

Does anyone know where to get a regulater from?

[Thunder arrow]

Re: PMEUMATICS

* Working Pressure: 1.5 - 8 Bar

* Maximum Pressure: 10 Bar

my bars is going to be 10 so... maybe not

[jonny]

Re: PMEUMATICS

i'm gonna be running on 10 bar with it, will be interesting

Re: PMEUMATICS

HAHA !!!!
good luck :shock:

Re: PMEUMATICS

i'm gonna be running on 10 bar with it, will be interesting

tell me how it goes hoplfully well
and my cylinder is max psi 145 and i am using it at 144 so........

Re: PMEUMATICS

back to regulators,
the ones on tecnobots## have a high(ish) flow rate but a low pressure rate (only 7 bar max outlet and a 10 bar inlet)

##http://www.technobotsonline.com/1-4-...regulator.html

i need a regulator with bsp1/4 conections, dont mined on the flow rate but not to rubbish and pressure rate has to at least 10 bars outlet and 69/68 bars inlet... so Any ideas on were to get one?

Re: PMEUMATICS

I got a Co2/Argon regulator 60 bar inlet 10 bar outlet
Its pretty hefty thou :/

May have to pop the question to Borrow on long term loan the high flow regualtor out of Dominator II

May have to pop the question to Borrow on long term loan the high flow regualtor out of Dominator II

where did u get it from? and how big?
the only prob with long term loan is that it would mean buying it forever and the peeps from Dominator II mite need it again so
