@@Differentthings2006 just the one in the unloader is ok, I noticed yours doesnt start to hiss and the engine rpm changes as there is no load when up to pressure - not sure from the video, maybe the leak in the tank is affecting it so it doesnt work as it should. I will do a video of mine soon, it took me ages to get all the pipe fittings mine is metric and BSP apart from the unloader which is US so is NPT thread.
@@EngineVids It makes more of a popping sound then a hissing sound. I think this is because there's a check valve in unloader self, and in the tank, so air gets out at first, but then can't continue to be released for a second because of the tank check valve. To me, it does not sound like there's any rpm change, but the diesel engine is pretty good at holding a consistent RPM.
It's quite normal for compressed air to be hot, and it will heat the head and tubes coming out of the compressor. The compression ratio is not equal to the diesel, but the heat is very normal. Think about it. You're using a diesel engine. No spark plug. No spark. The source of ignition in that engine is the air being heated by the compression. When it is fully compressed, it's hot enough to burn the fuel. The air in the compressor is not getting as hot, but it will blister your finger.
It's true, like you said compression ignition requires high temperature to ignite the diesel fuel. And of course there's no ignition going on in the air compressor just the compression of air, causing a rise in temperature. I noticed that during the winter the air compressor doesn't get very hot because it's just so cold and I don't run it for very long periods of time since it only needs to run for a couple minutes to get to 100 psi.
V-belts you do not wanna run super tight, it will lower belt life and increase friction. A 1.5 horse motor could run this, although I suspect it would struggle and wouldn't pressurize as fast. The clutch is imperative to start the diesel engine, would be far too hard to pull it over if everything was connected solidly together with pulleys. It would obviously be more practical to use an electric motor like the one that came on it, but I chose to do this project because it was fun and was a learning opportunity, it also provides some benefits like being completely cordless and being able to run for much longer without damaging itself.
@@jtj250 2hp It was spinning the compressor at a slightly lower rpm than it is with the diesel engine, because the clutch has a bigger pulley diameter.
Nah dude that tank is JUNK extremly unsafe man that tank was probably never drained and its all rotted out on the inside. That tank is gonna blow up dude and i dont wanna see you get hurt.
I appreciate your concern for my safety, but I've taken this tank above the pressure that I'm going to run it at multiple times. My guess is that the damage was done not by rust, primarily, but by dragging on the ground. Tomorrow I will be coming out with a video that goes into depth on how I patched the leak as well as finishing this project.
