RE: hydrogen - 4/11/2008 2:45:15 PM    rtsurfer   Posts: 51 Joined: 4/6/2008 Status: offline Oh I see what you are doing this way you are in constant control. That will work. What gauges are you using? No I did not put pressure on the tank. I did plow into it and sealed of the outlet to see if there were leaks but now there are no leaks. I have a one way pass valve on the bottom so when the unit heats up pressure builds in the tank as it cools there is a vacuum when the air condenses. It can not pull from the top because of that one way pass valve. This caused my lid to pull down and dimple.

If I can get it to work properly the hydrogen gennerator will be under pressure and then using that pressure use a propane mixer designed for my engine to introduce the hydrogen. IF I can do this I will be implimenting safety checks to shut the system down in case of malfunction (i.e. a pressure release valve, and pressure shut off switch,.....).   _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

I know the pvc can hold the pressure, my grandfather used it to plumb his workshop for air hoses, and those are at least 125psi and schedule 40. What I need is less than 125psi and I will be using schedule 80, so I think it will hold it. _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

RE: hydrogen - 4/12/2008 5:32:46 PM    northey87 Posts: 841 Joined: 10/17/2007 Status: offline Some more progress!!!! What I did today was build a pressure test unit. I took four plates and hooked up a positive to one side and a neg. to the other and then put them in to a 4" schedule 40 pvc and put a pvc cap on both ends. In one of the cap I attached a pressure gauge, and here are the results. I was able to build up 75psi!!! The next test will be how long it can hold the pressure. < Message edited by northey87 -- 4/12/2008 5:33:50 PM > _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

RE: hydrogen - 4/12/2008 6:47:25 PM    rtsurfer   Posts: 51 Joined: 4/6/2008 Status: offline The only thing I keep thinking about is the fact you are purposely build HHO pressure. If you are doing this find a way to keep you power leads at the bottom. Reason it if for some reason they spark BOOOM. Big time. Submerged if they spark less chance of a problem. I just got finished adding a second HHO booster to the blazer. I moved the bubbler closer to the engine. And in place added the second unit. I only brought it up to 8amps cold for now. I want to bring the other unit down to 15amps warm. I opened the first unit today to see how everything was. Only used about 200ml of water in 4 days. Not bad. I will get pictures tomorrow. I drove it around a little but the older unit is pulling too strong for 2 to be running. I did not put them in series. Just playing with it for now. (in reply to northey87) Post #: 136

RE: hydrogen - 4/12/2008 7:07:47 PM    northey87 Posts: 841 Joined: 10/17/2007 Status: offline The power leads in the test unit were at the bottom, and they will be at the bottom of the main unit when I get it built. But still 75psi is pretty good, that means I can get the pressure, but the next issue is how fast can I build up the pressure vs. using it up. _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

I have noticed that the rate of decompression has slowed way down, the first hour it loss 5 psi, the second hour it lost 4 psi more, and in the last three hours it has only lost about 2 psi. _____________________________ ''95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.
