Yep. Push movement has more power than the pull movement. But pull movement has more speed than the push movement, because the volume that needed to fill the pull room is smaller.
@@tjn1017 that is what i said bruh are you ok? The “empty” space gets emptied when pushing and filled with air when pulling. The space with the rod gets filled when pushing and empties when pulling
It’s nice to see, but rare since it’s almost not worth it with how shitty the creator fund works, you could have a billion views and countless likes and not get a single cent @masteroogway for reference
This is not true. This is strictly based on exterior atmospheric pressure increasing per volume due to elevation. Which is why most hydraulics are positioned vertically not horizontally Unless based on a pressure system i.e. external force power.
This is correct if we keep the same working pressure. In the case of needing to do the same job, you only have to increase the pressure on the rod side.
It’s easier to just design the system to have enough pressure to pull with sufficient force, rather than have 2 different pressures. The push stroke will have some extra force but it usually doesn’t matter. What is often a more annoying problem is that the cylinder extends slower than it can retract, because the piston side has a greater volume to fill than the rod side. This can be solved to a extent by recycling the oil coming out of the rod side into the piston side instead of going to the tank. This is called regeneration. This doesn’t work when extending under a substantial load tho.
Extend/Retract > Push/Pull. Most confusion stems from nomenclature and language barriers (technically hydraulic systems dont pull. The pump is already creating pressure, which makes it easier to switch sides of the cylinder instead of having a positive pressure pump and vacuum pump for each side)
It depends on if you are talking about the hydraulic system or the mechanical system it's operating. For instance, when the hydraulic system is extending the rod, it is Pressing on a hydraulic press, and Lowering on a crane outrigger and Lifting on a forklift and Pushing on a trash compactor. And in this animation, it's pushing the rod out and pulling it back in, even if the pressure is still Pushing on the rod end of the cylinder. It's all about perspective

Oh you should do one for how if you connect both sides with lines and pressurize it, it'll extend a lot faster since the pump is only replacing the volume of the piston rod. It's called a regenerative circuit. It'll extend fast with less power and retract slow.
I had to work that through in my head but I can see how it works now. I thought the two would just fight each other and slow it down even more, but really both sides are just expanding and spitting the piston out by replacing the metal volume with fluid as if it's just a steel rod with its end sticking out of an airtight hole in a container of expanding fluid. The force is pressure x the cross sectional area of the ram, so not quite as much as either the push or pull (unless the ram is really thick). Well it will be the push minus the pull actually.

Speaking from someone who rebuilds em on heavy machinery from time to time,when the lines pop like popcorn or the endcap seals fail, there is a mess and/or carnage left behind on most occasions. Most hydro line fails end up dumping around 5 gallons. However, i have had to put up to 60 gallons after a main feed line blew, and the operator ran the excavator(cat 330bl) until it stopped moving. Hydraulics can be very dangerous
Yes this is called the anular area(the side of the piston with the rod) and the full Area(the side of the piston without the rod) Aa=Af-πxR²(Rod) Or it can also be calculated as Af- πxD²(Rod)/4 this is also true for pneumatic systems as well.
Could you possibly make the piston rod side like a concave ish shape and keep it flat on the bottom so that there is more surface area on top that equals that of the bottom side?
You'd just add perpendicular force components that cancel out (that is, if the shape is symmetrical. If it is asymmetrical, there should be a force pushing the piston to one side of the cylinder wall, which also doesn't help.)
The surface only matters if it is perpendicular to the direction of the motion. By making it convex or concave you wouldn't increase the perpendicular projection of the surface and thus it wouldn't change anything.

The hydraulic power is determined more by the pump than the cylinder. Because while there is more positive pressure going one direction there is more negative pressure going the other negating the statement in the video. The direction of the cylinder is really just a storage reservoir.

Wouldn't the piston also reduce the volume in the upper half, thus the air would have to fill a smaller space and would be denser. Wouldn't this denser air then apply a greater force and equalize this disparity?
Nope, because the volume decreases at the same rate on both sides, as in when you move the piston halfway, the pressure doubles, and that works for both sides. It would only apply if the amount of air is the same on both sides and that's not true due to 2 reasons. 1) the piston rod doesn't displace the air on the other side, it replaces it so the pressure equalises. 2) it's hydraulic, so there is no air

Didn't know of their existence. Thanks, they seem interesting. I expect they would not have this problem. But at first glance they seem more fragile in general.
Why did you put this script? (Even though its the same pump) So youre assuming that if its not the same pump it still cant push harder than it pull? you messed this up. if you put 10hp motor on push pump and 1hp on pull pump. itll push more than it pulls, so why are you teaching WRONG things?
I was studying to be an engineer but changed to psychology. These videos scratch the engineering itch like nothing else I’ve seen in the past few years since switching.
This is a beautiful example of hydraulic power. People sometimes think if I will put a bigger engine on their wood splitter they will get more splitting power. Unless your splitter is under powered for the cylinder it has a bigger engine is not much better. You need a bigger cylinder.

You can use this mechanical advantage to create more pressure than the pump pressure is putting out. It does take a little time we maxed out a pressure gauge in hydraulic class. With check valves and sequencing blocks you can build incredibly high pressures. You can retract faster also by using that pressure differential too. Unload cylinders can use the extra flow in amazing ways.
You can also send pressure to both sides to rapidly extend the cylinder. It's because the shaft would effectively reduce the volume of the cylinder so you need less fluid. But it also means you have much less force
At work I run a Takeuchi skid loader a decent amount. I had noticed that the attachment locking mechanism locked much faster than it unlocks. The piston lengthens to lock and shortens to unlock. This explains everything.
Lol I actually thought of this as a variable before seeing this video. Also the size of the hose port in a hydraulic ram can also effect performance. A smaller port with less flow creates more pressure inside of the ram compared to a larger port with more flow.
Ok, for our next lesson, apply equal pressure to both sides. Which way does it move? This is a basic principle used in automatic transmissions since their inception. Now do a search for "regenerative valve" primarily used in loaders. I put one on my log splitter, time saver for sure!
It also applies to pneumatics. Worked with a bunch of pneumatic pistons a while ago and while the cylinder was capable of pushing ~35 kg, it only pulled ~28 kg.
I currently have a cylinder on my bench that has a rod out both ends, so would be balanced. The rod out the other end is used with a scale to measure displacement
Paused this immediately. First thought through my head was, no kidding. Less cylinder surface area to draw back the ram. That’s why very few things powered by hydraulics do the work on the pull, although there are exceptions. Also, the ram seals usually aren’t as durable as the ones on the piston.
For a guy that has never worked in hydraulics, you did damn good! Highest honors, in MY school! You are absolutely right! I’ve had to work with a lot of people that don’t understand simple physics, and it’s absolutely frustrating when you have a so-called mechanic working on your stuff that doesn’t understand these simple processes!
yep, to counter this, there are rapid escape valves that give the liquid an space to escape faster; as a curious fact, the contrarious of this are the strangler valves, wich uses a little trothel wich permits the pass of more or lees fluid
Intuition always told me that hydraulics can push harder than they can pull but never considered this to be the reason, as I've never actually consciously thought of it until now.
Damn. I never even thought about this, but it's so obvious now!
