Best spent 10 minutes and 47 seconds on KZfaq ever. So much information in a simple way.. Not sure how many times I have gone back to this and your other films to learn and refresh my memory.

this is one of the best videos I have ever seen explaining the function of the load sensing. thanks for this great add.

Very well done , thanks for making these very informative videos for all us trying to get a good understanding of our machines hyd systems. Between you and lunch box sessions I've got a pretty good understanding of the closed center load sensing. I've got a excavator that uses a open center negative control system and would be very interested in seeing a demonstration on how that type of pump control functions. Thanks a lot for these great videos!

The best way of teaching sir .. I never watched video such type.. you made wonderful tech video sir . Thank you so much

Hydraulic pressure composerted flow control valve very good Video. Thank you sir.

Excellent explanation.

Thank so much you sir. Just trying to figure out the load sensing and pressure controller interaction with the swash plate from the Rexroth or ROV manual was a pain. 10minutes spent with you and it was obvious! Much appreciated👍

Good explanation. Stroking and destroking. Couple of comments: 1. Pump discharge port not mostly go to close center valve since most load sensing valving system use "float center" type or any valving system having "closed P" port but with outputs A/B goes to load sensing port thru shuttle valves. 2. Technically the load sensing line can't have a "zero" pressure since height of the column of oil or trapped oil pressure could still exert force against P pilot lines. I'm pointing some emphasis on 2 because you might create a "void" in the load sensing line if the piping system is not proper and could create some erratic functioning of the system especially at starting. There might be applications where the valving system is higher than the reservoir which might not ensure to complete filled pilot or drain lines. Good job btw.

The coloured explaination made things more clear. Thank you

very good explanation cheers! actual valve is from rexroth and hydrulic schematic from vickers

I can fix problem with your explanation, thanks a lot sir

Thanks alot! Very well explained, finally i understand how it works

Many many thanks for the explanation in depth.

Thank you for this ❤️

thank you. I've been reading and reading. my teacher should just show show the class this video

Very nice example

That was an amazing video mate. Very well done.

Thanks for educational background for learning

je suis francophone mais merci de votre explication

Thank you for your beautiful presentation. present an lpvd demonstration of poses

Great video, thanks!

Küçük olan ayar LS hattı 25 ila 30 bar a ayarla , büyük olan ayarda çalışma basıncı bu kadardiki zaten , ama siz hidrolik bilmiyorsanız fazla karıştırmayın Hidrolik çi hatasını toprak örter 😊

thank you 👍

Loving it! best explanation I have ever seen

So L.S. pressure doesn't stroke your pump but prevents it from destroking by blocking the oil to the destroke piston until the pressure setting of the pump cut off is achieved?

Thank you so much for sharing this knowledge.

After 5 years i fond it Thinks master

Great video, clear explain. Thank you so much.

Thank you very much.How to control case drain?

Very good videos but I would like to see a video with the explanation on the bearings and adjustments of them also the sealing what type of sealing use in this type of pumps thanks

Nice video to explain load sence and about compensator valve, but which case we need to adjust both valve,

Good 👍👍👍👍👍👍

I have one the cycles on and off moving swash plate as motor runs. Set at 300psi and 3000psi. If i lower to 1500psi cycling stops. Internal leak or broken spring? Oil gets very hot. Forks on forklift will tilt down un intentionally if I set at 3000psi. Execellent video Thanks.

Nice explanation on Load Sensing...do you know have any video simulation of the Rexroth with said load sensing....or maybe you know of some youtube showing this...please add a link as well.

thank you for the educational video

Thank you for your videos I'm really excited to see more. Please,could you help me out maje a preventive maintenance schedule for hydraulic system

Good point on getting the diesel engine started...

sir bring its second part

well done thanks

thanks sir

thank you. interested in what happens when work is being done on the output side of DCV? How is swashplate angle maintained during work output?

Excellent instruction Thanks

thank u

Thanks!

Hi. I have a pump like this. The label says DFR but there is no load sense line. Its set up as a DR sense system. Im not sure im under standing the function of the DR system. Bare with me..lol Im working on a telehandler. It has a open center spool valve with hydraulic pilot controls. System pressure is suppose to be around 3100psi. SO to set the DFR pump up in DR mode, According to rexroth, you screw the load sense control all the way which blocks the sense ports to the pump. Now you set your system pressure buy screwing in or out the pump pressure setting. (3100psi constant pressure) SO my question is ..am i understanding this correctly . With a open center system with no load sense line (DR), the pump is always putting out 3100psi If thats the setting pressure, and when you activate a function the main system pressure drops which is sensed through the pressure limiting compensator port going to the de stroke piston. So when system pressure drops on command the swash plate de stroke piston spring pushes the swash plate to stroke direction to maintain system pressure of 3100 psi. Am i getting it?

Thanks a lot buddy it is really helpful.

nice! waiting for the other videos!

Please make more AC videos like your "Neutral wire explained". Eg. "How to work with capacitors on single phase"

Hi We have a variable displacement piston pump.... It is not giving pressure... Load sensor checked and found OK.. Still the same problem occurs... Pls guide me how to resolve this issue...

We have a issue with rexroth pump 3000 psi which is frequently replace new pump but pump not working in neutral position will you advise what is the problem

this view is only for use veriable displesments axile piston pump thans yous giuedness

Thanks....

Very good video. What is the purpose of the "small hole" on the pressure compensator spool? Is the spool hollow inside? Can anyone clarify please? Thanks.

I might be wrong, but the drawing on the pump side is a bit confusing tho. The destroke action of the pump contradicts the direction of arrow (angle), and this seems confusing to me.

Witch one Valve can give me co trol HP and flow ? Manual or 12v ..i have a10vso28

thanks sir. good explanation

greattttttttttttttttttttttt

Nice video my boss.so Which one to adjust first.load sendsing or cmpnsator...?

Hello sir, Myself Ajit Nayak from INDIA, I have Rexroth A10VSO100-DFLR-31R pump. before few days my team replace rotary kit in this pump. i request to you pl. guide me to set up Pressure, Flow control as well as load sensing valve optimum setting. my CNC machine required pre. is 3200 PSI, 50HP Motor using in this system. Thanks.

Nice explanation did u make a part 2?

Awesome explanation of controllers but swash angle explanation is totally opposite to the convention. Swash angle arrow away from the pressure outlet line is considered as pump in full displacement and the same arrow, in line (Vertical) with suction and pressure line on the schematic is destroked.

thank you

Search by write : load signal hydraulic pum piston

what is DRF and DFR

Is it possible to (dead head) this pump to for testing?

Is ths up stroke and destroke in opposite direction.when the arrow comes near vertical it is minimum displacement.

DRS CONTROL

Can you send me subtitles for this video? I want to translate them into Russian for a better perception of information. For personal use. Thanks.
