Pretty cool! I like how you showed that you had problems. I have never done a project that worked the first time. By you showing the trouble shooting, it allows us who want to build this as well to add that interior extension the first time.

Nice idea with that reducer as the back of the piston. I don't have reducers with quite that same flange in my local stores. Good result. I was just talking with someone else about a project they were working on with these pistons and cylinders.

Thanks for the original video showing how to get the pistons setup! Last year from that video I was able to build a ridiculous 4" tennis ball cannon that would shoot it so fast and far you'd lose sight of it. I had some neat ideas for the trigger mechanism and building a kind of stock for it. I need to go rebuild it, but video it this time.

Very nice! Yes you can make some great cannons with these pistons. By the way, since the inside of this pipe is 2" in diameter and area is radius squared x pi, r=1", squared it's still 1", x pi = 3.14 square inches. So all you have to do to figure out the strength of a 2" piston is multiply the pressure used by pi. 100 psi of pressure = 314 lbs of push. Pull will be less because you need to subtract the area of the shaft from the total. You should add some rubber bumpers inside the pipe so the piston doesn't slam into bare PVC when it's bottomed out in either direction.

Excellent style in teaching. I realize, but not only that you realize you don't know everything, and that is the first requirement that makes a good teacher, but what you do know you teach well. Without that first requirement, you wouldn't be as knowledgeable as you are, because you questioned it and figured it out, you weren't afraid to admit you didn't know something, and therefore opened you up to knowing the real truth, that is a sign of actual intelligence. Your style is the best it gets, showing the failures right along during the process, showing how you don't give up or get too excited and break things, but just simply say "lets take a look" and you troubleshoot it and fix it in minutes.

Awesome video. I appreciate your teaching style, it meshes with my brain, well. It would be great if you could walk us through the math of pressure. I never took physics, but I understand the basic concepts.

Very very very interesting I am trying to build a streamlined camper shell which will require me to lift up a large part of my camper if I make 2 of those what you're looking at I could push up that camper using relatively low pressure air I should say the hatch to get in and also can get in through the the window between the pickup truck and this camper on building. One guy is using PVC give me foam as this piston and by compressing it at forces it out that's not a bad bad concept I don't think for low pressure. But the nice thing is by using a metal rod and and sheathing it with the PVC pipe you can have a real long stroke and control the compression of the whole thing without worrying about buying expensive bolts for your limitation

Awesome....!!! Thanks for sharing.

Great video. Liked and subscribed. I can't understand the 27 dislikes, it has to be the same person with 27 computer accounts. Great job on the build. Just a tidbit: One mole of air, on average, contains exactly 602,214,076,000,000,000,000,000 air molecules, which occupy (R x T / atm) cubic meters; where R is the universal gas constant (8.314), T the thermal dynamic temperature, or 273.15 + celcius temperature, and atm is the atmosphere in pascals (101,325Pa), so if you know your temperature and cylinder volume, you can calculate the number of air molecules in said volume, and using the ideal gas law PV=nRT, you can calculate the pressure increase by using ratios and proportions of the volume decrease; in other words, P1 x V1 = P2 x V2, and thus (P1 x V1 / V2) = P2 then you can calculate the Energy in Joules that the parcel of compressed air has.

That's what I was looking for Halloween. A compact pneumatic piston in order to make an animatronic to scare people. Thx and greetings from Spain.

Improvement ideas: inner diameter of 2" PVC = 2.047" outer diameter of 1-1/4" PVC = 1.660" 2.047"-1.660" = 0.387" (free space between inner diameter of 2" PVC and outer diameter of 1-1/4" PVC) 0.387"/2= 0.1935" (divide by 2 to account for both sides of ring.) Cross Section C.S. of ring must be larger than 0.1935" to seal. inner diameter I.D. of ring needs to be smaller than 1.660" to fit snug. Outer diameter O.D. of ring needs to be larger than 2.047 to seal. What size ring to buy: (size 326 is what I would try) has a C.S. of 0.210" - good has a I.D. of 1.600" - good has a O.D. of 2.020" - (bad by 0.027") But, considering the ring has to stretch by 0.06" to fit over PVC it will be larger and considering the C.S. is 0.0165 larger than the space available it should compress nicely. If you get the x ring instead of the O-ring, it will give two sealing surfaces instead of one. Link: www.allorings.com/x-ring-seal-sizes If you order it made of HNBR it will have the best abrasion resistance. Link: www.allorings.com/o-ring-materials-comparison Also, bevel the inner edge of the 2" PVC with a plumbers de-burring tool so the ring doesn't get damaged when inserting. Other than that, lubricate with silicon grease and you will have nice performance.

Cool. I hope I can do projects like this someday

@roninmakes4992

I think that's the perfect use case for something like this! You probably wouldn't need to increase the pressure. At 30 psi it's going to have something like 180 pounds of push force, and like 130 of pull force, if you need it to go faster you should probably use quick exhaust valves. But PVC tends to be rigid and can shatter if you go too fast, so test it out safely. Mine tends to leak a bit and I haven't found a way around it yet, so maybe putting something to dampen the sound around it would be a good idea, or incorporate it into the prop! Let us know how it goes!

Had to watch without sound, so maybe I missed some explanations. However, you need to watch some PVC glue-up video's, that was painful. Very cool overall though. How long can it run continuous before needing more oil?

I'm working on similar, but the o-rings just can't hold 40psi of water pressure, water leaks right pass them, even using two. I'm a bit stumped now.

Cool

how to make pneumatic cylinder (ये केसे काम करता है)

In the end i didn't hear any leaks, but i was wondering if it does? The reason i ask is because i wanted to build a air cylinder and piston but wondered if i would need to figure out something to stop the leak/s in those seals if any. The leaks might not hurt its application for many purposes, but for my purpose it has to be as leak free as possible.

Not sure what you mean by that. You're going to need something to hold the pressure. Depending on how big they are, you could have a small air compressor running off of an inverter that's plugged into the 12v socket.

The O ring is the same size no matter which way you are using the cylinder....so both directions have the same potential.

@TheRebelmanone

The O ring is not what determines potential force, the area of the piston is what he was talking about of which determines output force. And on the shaft side(the return/in stroke) of the double acting piston, he mentioned how the shaft size takes away from the available piston area that the return stroke air pressure can reach, causing it to be a bit weaker than the out stroke. and he is 100% correct.

What diameter of pipe to lift 3 tons a car up to 2 meters?

@roninmakes4992

4 жыл бұрын

All depends upon the pressure. And unless youve got a sophisticated lock system built around a cylinder like this, it's a recipe to have 3 tons drop from 2 meters onto whatever and whoever lies underneath. PVC can shatter if overstressed, pressure is an awesome thing, but you have to take strength of materials into account if you want to go down that road

this is dangerous: dont use pvc it explodes under pressure, use polythene high pressure gas pipe instead. at least for the outer. or wrap it in kevlar tape.

PVC and pneumatics do not go hand in hand LOL. Temperature, dropping it, and other factors can make these kind of things send PVC shrapnel in all directions xD

Corality The use of PVC pipe is common but NOT RECOMMENDED for use with compressed air. It is often used because it is readily available, inexpensive, and easy to install. However, as with many plastics, PVC gets brittle over time and can crack, break, or even shatter. Your cement won’t do anything if a crack forms.

Also, PVC will brittle up and whats fine now might not be in 3 or 5 years if it has exposure to sun or UV from metal halide high hat lights. Also, I believe it is pressure derated as temps go up. If it used anything besides intermittent, you will have friction and pressure heat build-up. A lot of kids and adults are hurt every year with their spud cannons.
