What I don't understand is how the fluid is being introduced into the piston. Wouldn't the pressure inside of the piston rise as more water is introduced, thus needing more power to push more water in?
it is because the pumps and lines work at (depending on the cylinder) a few thousand psi and it this pressure times the area of the cap on the back of the rod that determines the amount of force the cylinder can put out.
@@irongiant6112 Thank-you! I googled "how does a hydraulic cylinder work" and spent 25 minutes reading everything but the answer I was seeking. Your explanation is exactly what I was trying to understand!
Theyre playing using surface area and speed/leverage. Yeah sure the price you pay is having to constantly fight against the friction. Pistons are kinda tight and most of them cannot be shifted by hand. But what you gain is a "leverage" due to the surface area. Coming from a pump or bladder, the pressure is kinda high but the flowrate and volume of the oil is quite low. But since the pressure is equal everywhere in that closed system, the force you get depends on how wide the area of the piston. But the catch is that the wider the piston size (bore) the larger the volume of space inside the cylinder that needs to be filled up with oil. We have discussed how the flow of the fluid is quite slow. If you have the same pump, but then swap to a thicker cylinder, you will get a lot of force but it will push very slowly. Its like using a crowbar where you have to move the other end a big distance just so you can pry off something and moving the other end of the crowbar just half an inch
@@irongiant6112 that explains part of my question but some follow up questions if I may: 1. how is a small pump capable of creating so much PSI to move dozens of tons of weight? What is the origin of all this power? 2. Also, all this force, how could the cylinder assembly / hoses contain it? Like water, I would imagine the oil, under pressure, would seek an easier exit point than push against that heavy cylinder rod? 3. As the hydraulic fluid is getting pumped into that vacuum, would not the extreme PSI push back on the pump? I imagine the oil would want to exit via the hole where it's getting pumped in rather than continuing to get compressed. Also, how is the system able to remove that pressurized fluid without a blowout (ie during lowering of the bucket or scoop)? We are talking great force and you know what happens when you open a soda bottle that has been shaken. TIA!
I'll just build this for my exosuit arm part(basicly a hydraulic cylinder that makes 2 parts put your amr in the shape it is told to and hold that and then you have more power) now just to like, make it a 3d model. after that I only need a pump.

A nice video with good animations on hydraulic and pneumatic cylinders. Thank you for sharing such instructive content !

This is probably the best video Explaining hydraulic force applied to machinary.
Hi friends - nice animation.
Thank you, this is super useful, a clear explanation
Thank you! Very clearly explained.
absolutely fine animation to understand whats happening
Nice video and nice animation
very detailed explaination thanks !!
informative video, but what the honk is up with the textures on that 3d pump model? the flickering is distracting
Obrigado pelo video, me ajudou muito.
Please how can I get a model like this... I need one for a project
Well done

When the piston reaches its limits what stops the oil flow?
Hello. I would like to make your video my reference to create a book. Would you mind?
What I don't understand is how the fluid is being introduced into the piston. Wouldn't the pressure inside of the piston rise as more water is introduced, thus needing more power to push more water in?
I believe that the extending arm on the end of the piston helps alleviate that pressure
I still don't understand how a little bit of oil pumped into a chamber could create so much power.
it is because the pumps and lines work at (depending on the cylinder) a few thousand psi and it this pressure times the area of the cap on the back of the rod that determines the amount of force the cylinder can put out.

coz lliquid is a nearly incompressible fluid. coz pressure is force / area and coz Pascal's Law

circular sealer ring LOL you mean O-Ring
Oil pressure is a best for air pressure
Sir my i have your permision to use your video to my video tutorial,but i translate in tagalog to explain,hope you granted me,thank you
Steam engine cylinders are essentially pneumatic cylinders, it occurs (duh) to me.
Why they spell single like that though
