Hi. Look at my first pcp compressor video . There are any information.

But why do not giveing description of the accessories or metrials pls give me that link of parts and how to make it

Thanks for watching

Thanks

What is the stroke and plunger diameter in both stages? Motor power?

6mm 10mm 100mm 1.5kw

Well thank you. I made the key in my workshop. Unfortunately I don't have a video with him.

Yes

Thanks. Classic compressor - help with 8bar

Thanks . The cylinders are from aluminium. The pistons are solid carbide rod.

I don't have it at the moment.

@@PaulXchannel Ok. Thank you in any way. And what is the diameter of pistons ? 1st and 2nd stage you are using?

First piston 10mm . Second piston 6mm. Stroke 120mm.

in the same way

I made the check valves.

Viele danke. Ich habe das Geld nicht gezählt es ist ein Hobby. Füllzeit eine halbe Stunde.

Thanks for watching. I don't have a measured filling time. Approx 2-3h.

the piston is a carbide semi-finished product - it is not machined

@@PaulXchannel So where you found it? Yup, carbides are hard but that rod before must have been lathed

@@PaulXchannel thank you

Thanks. First piston 10mm . Second piston 6mm. Stroke 120mm. Material of pistons solid carbide rod.

@@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?

@@paulosoarescarvalho6219 Yes. There are one-way valves with 90° hole.

@@PaulXchannel How do you did one-way valves seal? with o-ring? And where is that seal? Inside cilinder?

@@paulosoarescarvalho6219 A plastic ring. In first part . ( cylinder head )

Made in my workshop

Damn!

No you wouldn't of

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."

8bar

Now only with air

I think if I turn off the two fans it's about 65-70 degrees celsius.

@@PaulXchannel Do you think that is because of the friction of the compressor moving back and forth, or the compression of the air?

Large rotating mass.

@@PaulXchannel thanks 👍

​@@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.

No, I'm not building.

плохо вышло ( , правда

I don't use any glue - only oil on the O rings.

@@PaulXchannel what oil? Silicone oil?

@@bangagih It can also be machine oil. Mixed into the air in the device.

Not for sale. Thanks.

Hola! Cómo estás? Dónde vives? Para piensas usar algo como esto? El fabricó casi todos los componentes.

Cuanto cuesta el kit completo

@@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

España, y el compresor lo quiero para una carabina PCP. Ya se que los venden hechos, pero me gustaría hacerme uno y así me sirve de entretenimiento

@@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.

Not for sale. Thanks for watching.

I don't know. It is a hobby. I did not count the cost :)

@@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

I wish you a lot of success in the construction - thumbs up for people like you.

@@PaulXchannel thank you, it means a lot

Sorry but isn't for sale.

@@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?

Thank you for watching. Unfortunately I have little time to make new parts.

inner diameters I mean

10.1 ...... 6.1

Thanks! Do you filter oil from air after high pressure compression?

@PaulXChannel

I don't filter

I'm sorry, it's just a hobby.

@@PaulXchannel ok cool I use to make stuff but if I can repurpose stuff I will now time vs money hard to have both

@@markhall912 O.K. Cheers.

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.

350 Psi = 24, ..Bar
