problems with burst disk cannon
Posted: Mon Jan 29, 2007 12:08 am
This weekend I was bored so I made a small burst disk pneumatic. It was originally designed to be triggered by a blowgun and I assembled it so.
However when I pump up the 2 chambers to their proper pressures and go to trigger it it releases the air in the secondary chamber, bursts the primary disk, but then the main chamber empties thru the blowgun. I know that the pressure is great enough to burst it, yet it doesn't.
Is it as simple as having too small a chamber(18" by 3/4") and therefore not enough flow? It was going to have a 2" by 12" chamber, but my ace was out of couplers.
thanks !
