MadMan Posted November 26, 2022 Share Posted November 26, 2022 I've been messing around with a diaphragm I've gutted from an old keurig machine. I'm trying to learn more about gas compression methods, and the transportation of gasses. I believe the pump was intended more for water than air (gasses), which might be much of why I am having a hard time achieving higher psi through this pump. In what I've gathered so far: the weak point seems to be the actual diaphragm itself. The check valves should operate the same no matter what pressure is applied because of the counteracting forces. I believe I foolishly tried to increase the area of expansion and contraction of the diaphragm by replacing it with a balloon. It appears the flexibility of the latex inhibits the suction and repulsion needed to actuate the compression. Whether with the balloon, and some manual fiddling, or with the original diaphragm: I can only seem to get up to ~10 psi; if the pump is wet/damp, and ~8 psi; if the pump is dry. I've had trouble finding help online. I've mostly ran into people selling their pumps. I'd like to more deeply understand what is going on here, and if I'm missing anything. Any suggestions on what I could do to either improve my current process, or what fundamentals I'm missing to study up on to further my understanding would be greatly appreciated. Thanks in advance.
