Yes but what I’m finding lets say I adjust the cracking effort to 1 with a tank @ 1000 psi and then install a tank @ 3000 psi and recheck the Ip it will be at .7. Static Ip lockup is fairly consistent @ varying tank pressures but IP recovery after the valve opens is lower (with low tank pressure) and this changes the measured effort in this case .7.
They may have know that and knowing that would make a terrible accumulator they stepped up to help.
In the presence of vacuum the bags volume may prove insufficientWell you could configure the wine bag inside the box for the accumulator bladder.
Yep I get all that... but it’s different now that we are Continuously flowing the second stage isn’t it?. First stage locked up valve closed IP 135. Second stage sees the 135 with its valve closed. It’s been adjusted so the 135 and spring tension balance to keep the valve closed. Now we turn up the flow to create the vacuum needed to open up the second stage valve. Now the second stage is flowing. First stage valve opens and IP is no longer 135, unless you measure effort as soon as it cracks open your measuring for the most part the effort at 135. Now it’s trying to maintain +or- 10 psi in my case tank pressure makes a different where the IP ends up while it’s flowing. And the small downward change in IP means I need more effort to keep the valve opened at the same micro flow rate (5CFH) right? My 1st stage regulators when flowing at reduced tank pressure won’t regulate @ the original IP when the valve was closed. or just cracked, and this I find effects inhalation effort on the meter anyway, I see this in reg Savvy book page 175 at different flow rates the effort increases when the venture is set to min, and sense were flowing so little there is no venturing I’m guessing. So I’m sure at higher flow rates the effort goes up because it takes increased effort to compress the spring to further open the valve , but I’m thinking the small changes in IP also effects effort and with this small micro pump we’re seeing this where we weren’t able to see before with traditional cracking effort tests. I included a few picture above two different seconds same first stage at different tank pressures. Just playing and learning from you guys while cooped up in the house.
