The homemade pcp compressor to fill air guns and diving bootles. Assembly of main pistons. . . . for more interesting videos click ,, HERE " / @paulxchannel
I saw a video from India I think where they took two regular high pressure hand pumps and had a huge flywheel that was driven by a jackshaft and then an electric motor. So elegant and effective I must say I've been gathering parts to make my own. Thanks for the video
Minor adjustments to the counter balance so it doesn't go for a walk but otherwise it's a great build especially with the extra features like thermostat and safety glass.
Just finished watching it. That was very kind of you to lay it all out. I appreciate it. I suppose you own or have access to a lathe and mill. Im saving for a metal lathe, then im going to build a vertical mill and eventually my own 300 bar pcp compressor. Thank you again!
Excellent video and thank you for sharing 👍. Both pistons seem to make compression on the same time , shouldn’t they be 180 offset ?… So if 1 piston is compressing the other one is open or at suction ?…. Or can it be in this sett up because the difference in piston diameter ?. Is there more information to be found somewhere on the how and why ?…. Thanks again for a great diy project 😀
Hi Paul You fantastic work. I have a FX Impact. Using a cheap China compressor. After seeing your compressor design I would like to build my next one. I have the tooling covered, Okuma mill and lathe. Would you have drawings are list of your design? Don
Does the counterbalance serve any purpose? The motion of the pistons is driven by an electric motor… why the counterbalance? You might find thermal grease (on the cooling rings) would improve heat dissipation… but really, the detail on the cylinders is brilliant!
I prefer using thermalpaste in heat plate installation, it will improve the heat dissipation much better. You can find it in computer or electrical parts store for sure.
Hi Paul. Very nice project. I am also making one. Can you please share me the size, material used in the block and piston. Also please tell motor hp and wheel size
Tolles Video und Projekt! War sicher viel Arbeit, was hat dich das ganze an Zeit und Geld ca gekostet? Wie lange hat es gedauert, bis der Druck in der Flasche auf 3500psi war?
I dont understand how the regulator/. Oil water separator works when its on the inlet side.. or why the high pressure line wasent used on its connection., wouldnt that too be at high pressure if its reading the pressure in the system? No comprende
Hi, Very nice job! Congrat! What is diameter of piston shaft first and second stage? And movement lenght (stroke)? The piston itself looks like aluminum with brass on top, am i correct?
@@PaulXchannel Ok thank you. And at second 0.54 of movie we can see two brass pieces with side hole ( i supose hole goes in 90º till top where spring sits). - Are this pieces one way valves sit on top of cilinder? How do they seal? Have o-ring or another kind of sellant inside cilinder?
HELLO, EXCUSE MY DARE, BUT IT WOULD BE POSSIBLE THAT YOU CAN GIVE THE DRAWINGS OF THE CYLINDER ASSEMBLY, I WOULD LIKE TO MAKE ME ONE. I THANK YOU VERY MUCH, GREATEST GREETINGS FROM ARGENTINA
Very nice! I understand check valves on intake to prevent exiting during compression, but where are check valves on exit to prevent compressed ait back into cylinder? Are they inside that cap that you screwed on cylinder top? Is piston made on lathe have you some idea to improvise it without lathe etc. Overal great construction.
Very impressive and interesting setup you got. How fast can you get 300 bar pressure in a 2 gallon tank? Can you make a higher grade faster compressor if ordered?
@@tylerdurdencotw I'm not sure Paul understood your question, so as a mechanical engineer I'll note that compressing air makes it hotter according to the ideal gas law: en.wikipedia.org/wiki/Ideal_gas_law Solving for temperature, you get T= (PV)/(nR) I suspect heat due to friction is negligible compared to heat from compressing the air.
If you look carefully you may notice that Paul is feeding the high pressure compressor from his low pressure compressor (~7 bar). Also, the rods/pistons of the high pressure compressor are different diameters, suggesting that the high pressure compressor itself has 2 stages - altogether that makes 3 stages. If you wanted bigger pistons delivering 300 bar pressure, you'd need a *very* powerful motor! Remembering from physics class: force = pressure * area and suppose you want a 50 mm diameter piston on the final stage: pressure = 300 bar diameter = 50 millimeter radius = diameter /2 = 0.025 m area = PI * radius ^ 2 = 0.0019635 m^2 force = pressure * area = 58904.9 N (13,242 lbf or 6.6 tons) and that only accounts for the final stage - Yikes! As Nikola Tesla once said of Thomas Edison, "His [Thomas Edison] method was inefficient in the extreme, for an immense ground had to be covered to get anything at all unless blind chance intervened and, at first, I was almost a sorry witness of his doings, knowing that just a little theory and calculation would have saved him 90 per cent of the labor."
@@antoniolaracalvache7676 Antonio en que país estás ? Tu puedes comprar un compresor desde los 300$ -3000$ dólares, para qué tipo de uso lo quieres y así te puedo recomendar algo y no tienes que pasar trabajo
@@antoniolaracalvache7676 le voy a preguntar si él te puede fabricar los pistones y las válvulas, pero no te recomiendo eso te sale más caro solo el envío a España va a costar unos cien dólares, sabes que este sistema tiene un compresor regular conectado? Esto es como un multi picador, busca un aparato llamado shoebox.
@@PaulXchannel oh thanks, i converted paintball to bolt action rifle, and i made a compressor from an old fridge, but the power wasn't sufficient. I have a lathe and a mill, but I dont have the money cuz Im 18 years old. I mean if its around 200 euros its not expensive. Thanks for the information Im gonna try to build it if its not that expensive
@@PaulXchannel. Hi Paul, thats a nice system and I would like to know if you would sell the necessary parts so I can put on together? And how much would this unit cost if it was ever build with that intention?
This unit will allow you to have 10times that pressure, I don't know why he built one but I can tell you how useful it can be to many, people with off-road vehicles have to deflate and inflate back and forth their tires a 3000-4500psi air tank allow them to do this during the whole trip. Another use for hobbies like, Air rifles PCP to 2000-4650psi, Paintball hpa makers, some airsoft guns and for the lowest end using between 200-800psi water rockets. You could use it for scuba diving, but you will need to have a very nice system of filters to ensure the air is clean and safe to your health. I personally would like to have one for my PCP rifles.
linear guide? HGR25 or 30? shit, this thing must have cost about 5k USD. no way I will DIY such a machine, just saw PCP air compressor on aliexpress at 158 USD. , 4500 PSI pressure, free shipping
No filters i wauld love to see how much water come out in the tank .!! Coz i use pump to fill my guns and iv seen shit loads ov water in my guns coz filter gets wet over time .!! Fuck that tank going bang !!! Coz rust eating in side out 😂
