Changed tubing to smaller liquid inlet and larger gas out let in an attempt to control direction of liquid flow, my check valve decided not to work, they wouldn’t open, I guess plastic air valves don’t like NAOH.
Anyway, the flow rate didn’t change stayed at 200ml/min, up’ d the Solution from 5tsp/L to 7 in 2 steps, noting the amp draw. At 6tsp/L it drew 7 a, and 7tsp drew 8 a start surge, and settled to 5.25a. some added output, but didn’t measure it.
I got to looking at the gas flow and saw that it was large bubbles, explains amp drop, trapped gas till bubble can free itself from unit. I lifted the tank, it was at a level where the liquid level was 6″ above the top of the dry cell, and about 18″ above the dry cell the flow turned to almost a milky flow, and amps went to 6.5. Set up a temp stand and checked output, it produced 200ml in 20sec, that’s 600ml/min at 6.5a.
Later today when I get back from work I’m going to bump the solution up 1 tsp/L till I get a steady 11a, unless I hit 1L/min first.
I’mworking on a dry cell that I will push water under pressure into the cell and control the gas pressure at the outlet. If you work the pressures right, you can reduce the gas bubble size in the cell and allow it to expand when escaping to the res. . Just keep the pressure in the cell where the gas is still submerged in water.
In scuba 33′ under sea reduces volume by 100%. So in theory if the limiting factor is gas bubble size, shrink the size artificially then release the pressure for harvesting.
Sorry, not 100%—50% every atmosphere is relative—1= surface 2=1/2 3=1/3 4=1/4 It is the same above sea level but takes 10’000ft to achieve the same. This is why people who are putting vacume pumps on the res. are getting such great production. They are increasing the size under a vaccum. But at sea level their production will likely be the same under the same pressures.
