pumps

[Danberman]

may i recommend that you incorporate some pumps into your electrolyzer. I built a small one a few years ago that used a small water pump to circulate the water around the plates. With the whole unit running i was able to easily produce a good sized flame through a ball inflater needle. With the pump off though i couldnt do much of n e thing. i susepect the pump is just pushing bubbles off the plates so that there is more surface area, but whatever it did it made an incredible difference in my output volume.

I Totally Agree. I also found this out a long time ago. The only problem is it adds to your total power consumption.

Old "Car Wind Shield Washer Pumps" ar fairly good for this application.

Using a Vacuum in the Electrolyzer, Also helps tremendously. I caused the bubbles to Greaty Expand and rize out of the solution Much Faster.
Problem is Vacuum Pumps are Not very common and Quite Expensive.

Ok, I understand the use for a water pump, that will recirculate electrolite, but I can not figure on my mind the way to sue a Vacuum Pump.

I think that Vaccum pump will empty of air the chamber at the beginning, But, when the gas starts to be produced, Whatt happens??

Could any one explain me that with apples, bees or whatever easyli can be diggested by mi brain?

Thanks in advance

I was actually talking about just a simple pump to circulate the water in your electrolyzer. I used a tiny pump from allelectronics that was used for a windshield washer sprayer in a car, which unfortunatly they know longer sell. Just having a flow of water over the plates made a huge improvement in gas production. Also, i would recomend trying to design your electrolyzer so that the water is moving upwards across your plates, so that they are pulling the bubbles up and off.

Finally, on a unrelated note if anyone is looking for a good unit to make an electrolyzer let me suggest waterproof conduit boxes. The one i had was about 6x6x4 and was made from 1/8" PVC. the lid was fully sealed and the unit was able to maintain a fair bit of pressure without leaking. Im not entirly sure what the one i used was designed for, seeing as it had no punchouts or connector ports of any kind, not to mention i pulled it from a dumpster. But a drill and tap solved that problem. The annoying thing about it was that i got backflash once and the lid just shattered and sprayed some nasty water everywhere. that was fun to clean up....
