Pneumatics

[Guest]

Weve all most sorted the pneumatics out on Leveller. The swicher clicks when we tell it to via tor RC. The solanoid clicks at the top when we tell it to. But when we open the the gass into the system the ram fires and wont fire again even though the swicher and solanoid still click.
Dose any one have any ideas what could the problem be?
Thanks

if you have a solanoid valve you might have it plummed in the wrong ports. been there done that.

could have done that, where do they go on envy?

i have stripped envy down but will let you know when i put it back together this weekend my exact piping system. why not try and swap the pipes and see if you get anywhere. i am sure you will find the problem.

What you using ? a 5 port

Cheers Shane, well have a play with it.
Yeah Simon its a 5 port solanoid valve

I think you just got the pipes back to front. Its feeding streight to the ram rather than being stopped then feeding the ram when opened.

Simons more than likely correct.

The port configuration is normally 3 ports on one face of the valve body and two on another face.

The middle port of the three is the inlet from your buffer tank or regulator.... the other two either side are exhausts and shouldnt have anything in them.

The remaining two ports will go to the extend and retract of the ram.

Ive been having a look round Hydras pneumatics system trying to work a few things out. Like why the flipper keeps getting stuck up and the axe down and a few other things too.

It is currently plumbed as follows:

Bottle - regulator & 1000psi prv - 12mm pipe - t piece to 1kg buffer - 12mm pipe - t piece to lp prv - 12 mm pipe to t piece - 12mm pipe to flipper and axe 5/2 valves

from 5/2 valves - 12mm pipe to activate - 6mm pipe to return.

First thing that jumped out at me was the size of the buffer, so Ive replaced it with a 2.5 kg tank.

Next thing is the amount of connections and ts in the system.

I have a small manifold which I can tie everything back to. IE: input from regulator and star connections to everything else. As I recall from school the fact that the regulator and the buffer are connected at this point should hold everything at the same pressure irrespective of leaks and everything else.

My question is, will this help or am i wasting my time?
