Greetings, and I hope this first post makes sense!
I have machine that uses compressed air. Rather than using a compressor for this machine, we are considering nitrogen gas since it's use is infrequent.
The specifics are a 40 Cu Ft Nitrogen tank, filled to nominal 2200 psi. at room temperature. The regulator controlled delivery pressure is 120 Psi. The machine cylinder volume is estimated to be 20 Cu In, but since it is a dual acting cylinder I would assume it will use twice that volume, so 40 CuIn (.03CuFt) per cycle is probable.
So now the question. How many cycles can I reasonably expect until the cylinder pressure drops to the 120 psi operating pressure?
Any help on calculating this would be appreciated so we can determine if this is a sensible direction to go!
Thanks
