Hey KleteeTech, no body could have explained this better than you. thank you so much! I have a question that i don't understand for some time. 1.the pressure in the house in the small pipes and the big pipes is identical? 2. In my house I have a pressure relief valve and it reduces pressure in my house system, how does it happen? the force that uses to lift the spring makes pressure loss ? -- the energy is being lost? therefore reducing pressure? after the relief valve?
you are actually very good, but one small clarification (sure you are aware of that): pump does not create pressure. Pump/EM creates flow. Pressure is created by obstacles in the hydraulic system; pipes and their resistance to flow, valves, pipe curves and (most notably) cylinders with their loads or hydraulic motors and their loads. Cheers, very nice lectures.
I understand what you are saying but I disagree. The pump will create just enough pressure to create flow. The resistant what to flow determines the pressure and the pump has to be able to "force" the oil to flow. That force is pressure. This is commonly mis understood. That is one of the main reasons pumps have a pressure rating
wow, such a beautiful scinece, I have just started to learn about hydraulic systems and by watching this video, i'm sure i'm gonna have so much fun leaning it, it's lovely.
Me too. I cannot thank you enough either. You explain very well and succinctly. I have subscribed. I also am considering buying your book Fluid Power Systems.
Really excellent video. If your pump has higher flow capacity than the piping system allows to fill the cylinder, the pressure in the upstream piping would be higher and the pressure regulating would have to operate? Is that correct? Thank you.
Thank you for a great video. I would like to construct a similar hydraulic circuit for instructional purposes. Where did you purchase the hydraulic equipment in the video?
Does anyone have the force vs displacement graph of a simple manual hydraulic jack ? I mean how the force changes when we use and press on the lever of a hydraulic jack ! I want to know the complete scenario : before pressing the lever , while pressing the lever and raising the object , after raising the object! I want to know how the force and pressure of fluid changes during the whole process!
Great video. One question, my 5th wheel slideout and landing legs are operated by the hydraulic system. There are no pressure gauges on the unit. Am I correct in thinking that there should be no pressure on the system if the pump is not operating? I had a hydraulic hose burst and the front landing legs were holding the trailer up because it was unhitched from the truck. I wondered if that meant the hydraulic system had to be pressurized anytime a landing leg was down or a slide-out was operated. Also how can I make sure that if I need to unscrew a hydraulic hose that their wouldn't be pressure behind it?
The point is, not only a pump creates a pressure in a system, but the gravity does also. So, you WILL have a pressure in the system ones your outriggers down and supporting your trailer.
not a bad explanation except pumps only create flow, not pressure. its resistance to flow that creates the pressure. also for there to be flow there must be a pressure differential.

What a fantastic explanation, I wish I had this knowledge when I was doing fluid mechanics subject in uni.
thanks
You are a wealth of information for me, I’m a new instructor in my trade school and your series has helped me tremendously. I can’t thank you enough
Great to hear! Where do you teach?

Great, this video has helped me to understand conceptually.
Appreciated 👍

Thanks for the comment and thank for considering buying the book. I like it haha.

Sound right
funny how this principle is similar to relation between voltage and current in electricity, thx for great videos and tutorials
That is exactly right. They are both used for the same thing. Transferring energy from one point to another. Different tech but same idea.
Thank you. Amazing and very helpful video.
thanks
Thank you so much..there are very useful information in this video for me..
Glad it was helpful!
Thank you for a great video. I would like to construct a similar hydraulic circuit for instructional purposes. Where did you purchase the hydraulic equipment in the video?
The Transparent equipment is from SMC.
Where do you teach?
@@KletteTech Currently in Ireland 👍
Very knowledgeable. Thanks for sharing it.
So nice of you
What will happen if we are accelerating the load? Will the pressure of oil increase?
No, speed or acceleration is not a factor.
Excellent video
Thanks

Very educative
Thanks for the clear explanation
Happy to help
Another great explanation. Keep up the great work.
Thanks Mike.
Pressure is the resistance of flow.
Does high pressure increase the flow rate?
Nice explanation.
Glad it was helpful!

@@sergeymariasov6845 Thanks for the answer. I am guessing with just gravity pressure there would not be much in this case.
This was very helpful. Thank you!

Smart

Very interesting🙄
Glad you think so!
