Simple Hydraulic System Working and simulation
Simple Hydraulic System Working and simulation
This video will explain about a simple hydraulic system working with animated simulation.
You can clearly understand various stuffs related to control valves, rate of build up of pressure, many other visualizations.

A few issues here. Firstly the simulation was taken from e4training.com and the copyright note should have been removed. Also the speed should not change with pressure. This was just a basic concept demo, not a proper circuit, if you notice the r/v opens due to the inertia of accelerating the load. That's why the cylinder slows. I'll check the r/v setting in the software and update it.
I've modified the simulation a little and made another video to explain thing better https://youtu.be/8JVuJQb5H08 . On the compressibility of oil point, we do normally say oil is incompressible, most calculations are based on this. However, when designing systems we need to keep pipe lengths short to ensure the system is stiff enough to be virtually incompressible. In reality, oil is slightly compressible and this does greatly affect the design of high-performance systems. In the simulation, we had exaggerated the compressibility to show its effects, but it was not really intended to explain much in this model. For example the spool centre condition is wrong and there is no load control either.
This entire presentation animation was stolen from https://www.e4training.com/hyd_courses/B1.html
name of program I simulate on it !
hi my teacher thank you for explain. What is animation program's name ?
No the relief valve is not the way oil is returned to tank while spool valve is in centre position, if this was the case you would be replacing pumps all the time as well as every o ring in the system constantly, oil has to return to tank under zero pressure when valve is in centre position
This is misleading! In combination with a fixed displacement pump like this you should always use an open center contol valve. It means that when the valve is in the middle non-working position the oil flow is free between the pump and the tank. That means the oil can flow free and almost no pressure is created, the pump can run idle. The release valve is only needed when the piston reaches the ends of the cylinder or to limit the power of the piston. This is how most common simple hydraulic systems work in practice. A closed center control valve, like the one in this video, should only be used in combination with pressure compensated variable displacement pumps.
What I want is a visual simulator that will allow me to mix chemicals by dragging them around.
There is no program like this anywhere on the internet.
The only thing I have is "Crocodile Chemistry", made in 1999.
It crashes a lot, including when trying a basic electrolysis of NaCl.
It pretends that when you vaporize aluminium, it just disappears totally.
Gear pump is running opposite according to the diagram in the video
thank you soo much sir
Someone should explain to this guy that you can’t run all ports blocked on the valve in center if you are running a gear pump. P should’ve connected to T. Jokes.
Very nice… which program?
Bnsr, vous pouvez consulter ma chaine il y a quelques videos sur les circuit hydraulique et merci https://youtu.be/_CMCJ-isE2E
Good articulated👍
but you forgot to show relief valve in place while returning from piston.
Fluid is incompressible

Sriram has NO copyright to use this simulation. It is an old version with the R/V set to low so giving a false output. the assumption is wrong and I've asked him to remove it. I've now modified the simulation and made another video to explain things better https://youtu.be/8JVuJQb5H08 . On the compressibility of oil point, we do normally say oil is incompressible, most calculations are based on this. However, when designing systems we need to keep pipe lengths short to ensure the system is stiff enough to be virtually incompressible.

Your system will overheat the hydraulic oil because the pressure at neutral is too high you make it an open center control valve
This video is not correct. It uses, without permission or copyright notice, a simulation from e4training.com where the r/v was set too low and is leaking. We have a correct version on our site and have asked for this to be taken down.
very bad sound quality.change this
why your cylinder piston comes down if neutral position… that is no good
Informative simulation… Nice sir
your spool valve is wrong this is a gear pump and needs to have p linked to t in the neutral position or the relief valve will be blowing off all the time
Sir awesome explanation. Please add your videos on tamil also…by that subject will havr been very clarity than this.
pls give people the correct info, this is nowhere near to a simple hydraulic system, u dont build a circuit with a pump running under constant load, I won't even go further
In piston and cylinder block, I think the piston must be settled on a level above the lower orifice port not in line with it, so as allow fluid to enter the cylinder below the piston and push it up in the case of lifting.
Oil is getting compressed? Seriously
thank you for clear explanation.
