Hydraulic jack - How it works - Animation
A hydraulic jack uses a liquid, which is incompressible, that is forced into a cylinder by a pump plunger. Oil is used since it is self lubricating and stable. When the plunger pulls back, it draws oil out of the reservoir through a suction check valve into the pump chamber. When the plunger moves forward, it pushes the oil through a discharge check valve into the cylinder. The suction valve ball is within the chamber and opens with each draw of the plunger. The discharge valve ball is outside the chamber and opens when the oil is pushed into the cylinder. At this point the suction ball within the chamber is forced shut and oil pressure builds in the cylinder.

Good video !

[@BottleJackBuddy]

Good video.

[@TheGoti123]

Super explanation. Keep it up. I appreciate your valuable work

[@IradukundaSauda-vf5nq]

That is good oparetion and tank you for that

[@anilsharma-ev2my]

Any app which shows the calculations as the simulation working ? It's become boon in hydroulic industrial training

[@barriejones15]

Most jacks have a port to allow the top up or refill of hydraulic fluid, many have an overload valve preset at the factory, it seems this has neither.

[@binil2168]

Super

[@BillPalmer]

Would be better to show the cycle several times. Showing it once without pointing to the specific valves referenced requires backing up the video to see it

[@luckyPiston]

So how much force is required at the end of a 2 ft handle for the jack to lift 12 tons ? let's see if even one person can answer this question in the next year !

[@BillPalmer]

Lucky Piston Give dimensions of pump piston, lift piston, length of handle and distance to fulcrum point

[@rcarioca]

Does that mean that when oil is sucked out of the reservoir, there is a vacuum left behind ?

[@hindicreations1075]

How we made it

[@davidgruen7423]

Question, when the piston reach the end of its travel, where does the rest of the fluid go?

[@luckyPiston]

It should only go one place, past the pressure relief valve and back to the reservoir, that circuit is not illustrated here, sorry you had to wait 8 months for an answer !

[@judeoniti1598]

How did the oil get to the reservoir I the first place

[@thedudeamongmengs2051]

There's usually a valve to fill or refill the reservoir

I don't really understand how such small effort result in such powerful lift, I guess it's the accumulation of pressure and the lever effect, but I don't get how the pressure can allow the ram to move freely while staying almost perfectly sealed. I guess I'll have to learn about hydraulic physics in the first place

[@jacob4012]

The check valves only allow flow in one direction, and as for the lift, I believe off the top of my head that that is similar to Pascal's Law where a gas exerts equal pressure on all sides of its container, though in this case it's the force of pushing a small amount of oil into the cylinder makes the piston go up, as the oil is very hard to compress and it's easier for the piston to go up than it is for the oil to compress.

[@bruceanderson4114]

It is similar to sprockets on a bicycle, the Piston you're pumping is much smaller than the Piston you're filling, the smaller the Piston you are pumping the more pressure you're going to be able to create, the bigger the pump the less pressure but more flow and the smaller the pump the more pressure but less flow.

[@ahmedalsadik]

The valves are not numbered in the explanation text. This is very poorly done.

[@creamcheese3596]

Well that explained nothing.
