Pressure Differential and Cylinder Movement 

Thanks Kettletech, i just want to let you know your selfless sharing has really helped people like me.. cleared many doubts.

Very good example to show the mechanics of what's happening. I wish I had seen this earlier in my learning.

A subtle and simple explanation .. Thank you sir

Awesome demonstration, you have a true gift for teaching! You seem to have found what you were meant to do in this life...

Thank you very much you have a gift of teaching.

Great video. I like the visual demonstration

Simply perfect explanation

it helped me a lot sir.I have a clicker press and your video helped me a lot in understanding how it works.thank you.

Thank you for explaining

Very Nice and Simple way you have explained it..

congratulations, great explanation!!

superb ...

Too good explanation sir 🙏

Thanks a lot, it helped me a lot

Sir you are Great 🙋🙌❤️👍

well explained.

well explained...

Very good.

Simply love you sir

Amazing easy to understand thks

Thanks

Very well explained But it's the force due to pressure acting on an area that decides the direction of movement If you have equal प्रेशर on both sides , cylinder wI'l extend

Thank you sir

Thanks so much i really enjoy it, But i have a problem here if i fully extended my luffing boom it will come down automatically pls what could be the cause of it

Yes I got understood

Thank you for such an excellent explanation. Do you have some book to recommend regarding pressure, flow and hydronics? Thank you!

Dear, your instructions amazing ,, do you accept that atmospheric pressure is 14.7 PSI NOT zero,,,,thanks

Pura vida

I have injection molding machine and I have problem with movable plate it’s retracting alone slowly without pressing anything on the control panel ! Anyhelp please

سلام 👋 بزرگوار استاد تشکر وهزاران 👍.. هرکجا که هستین تندرست وسلامت باشی لطفا گهگاهی ویدیویی از اموزشهای خوب هیدرولیک هم زحمت بکش....زمان زیادی است که ویدیوی جدید نگذاشتین ...استدعا دارم حتما اقدام نمایید...ممنون و 👍....

I need to know how to build a system for two cylinders to move the ( same ) under different loads in and out ?

I have a trailer when the oil is cold it will only lift 3/4 of the way up and stop if you wait until the oil is hot then it will lift all the way up most of the time can you help me with information how to fix it thank you.

what psi if we want to stop under load and stop it right there like forklift.

Sir... 💖💖💖💖🙏🙏🇱🇰

Hi I think that when the shaft is going out of the cylinder to move a 400 PSI load, and the pressure in the right side compartment is 150 PSI, then the pressure in the left side one should 400+150= 550 PSI or a bit more. Do you agree?

Good teaching Thank you so much sir I want to learn more can you help me

I have a problem with retracting rod of the boom cylinder at a new miniexcavator. It's pilot operated spool. I checked everything but the spool itself and the components. When retracting rod into cylinder it is an obstruction as it doesn't let bottom oil from cylinder to go freely back in the return line/tank. After 100 hours , this problem laminated my hidraulic oil and really broke his molecaular structure and turn it brownish dark (Iso VG46) and heats above 80 degrees celsius. Is it posible that somehow the joystick pilot pressure isn't enough to push the spool proper into corect position and the return line is chocked? Maybe the spool spring too stiff? Any help apreciatted. Thanks.

9:12. What if you have equal pressure on piston and the rod side. What will happen. I am guessing it will extend because of larger area of piston and hence larger force. So I think it is the force which decides the direction of the movement not the pressure. Please correct me if I am wrong. Great video appreciate it

That piston would slam the blind side so hard into the housing

i thhink during extension .. pressure on right side will be more than 400 psi due to pressure intensification . Is that right ?

Stupid question, but why exactly does the pressure drop in the rod end of the cylinder barrel when the directional control valve shifts? Because that part of the system is now exposed to the atmosphere via the tank? I'm not too bright, but I'm trying to learn. Tired of breaking my back doing manual labor in a fiber plant for $13 per hour.

Practical problem in hoisting : Cylinders r not hoisting up or down with solenoidal valves. Upon Maunally pressing the solenoid valves, cylinders moving up n down. So, there is a problem in valves. To check this, we want to remove solenoidal valve from the circuit. Can we remove valve with the cylinders being in up position ???( pump supply in off position)

Hey Pat!

nice more tutorials

what course air lock on a double acting cylinder

Dear Sir..........I have single acting a cylinder with a bore of 18 mm and a rod of 10 mm and a stroke of 300 mm. I want to know what is the pressure if my cylinder presses 10 mm ........... Please advise and provide a solution with the formula

Hello sir i need one type hydraulic drawing explained sir

How servo valve for lvdt

Not an engineer but when you say pressure relieve valve releases all your oil is it accurate? I'd guess you mean the overpressuring oil only not all of the oil right that would defeat the purpose of a pressure set pressure release valve?

You didn't mention that between directional valve and relief vale there is a non return valve. This would confuse people

Svp explication en francais

Pressure doesn't move pistons. Force does. The pressure on the rod side can be higher than on the cap side and yet the cylinder will still extend became the cap side has a bigger area an a greater for e.

Force = Pressure (psi) x area²"
