Video Description

Visit hidraulicapractica com. You can see the interior of the motor, gears, body. Watch how the oil is pushed into the inlet port and through the oulet traveling between the gear teeth and the gear housing, generating the rotation of the shaft.

from hidraulic engime i got 2200 rpm , to bring it down to 60 rpm is it better to use a gear box like electric engine have or is better to use that valve to reduce amount of hidraulic fluid going tru engine??

i have 2 question about hidraulic motors....it is better to use a gear box to take down rpm or is it better to use that valve so you have less hidraulic oil runing in engine?...less oil runing tru engine dosent mean less power or torq? ....and an hidraulic pump can perform same if is used as a hidraulic engine? i have this tipe of pump like this on in the video and i whant to use it as engine for water well drilling machine and there i need max 60 rpm per min

@bryncomeaux cars are hydralic. any automatic transmission is all hydralically controoled. look up torque converter. its a hydraulic turbine

what prevents the gears from turning inward and going in reverse?

depends...lol

if you want to build a press and you need torque, use an hidraulic pump to give 50 tons to your press, ;)

Which side of the system is it best to install a variable flow control / needle valve and does it depend on the function of the component?

Does this sort of work on a principal like a rotary engine? I drove a forklift for years and always wondered how they worked, thanks! :)

I learned recently that case fluid should not be filtered due to potential clogging of the element due to neglect. When this happens, the shaft seal could potentially fail due to excessive case pressure. There are also two schools on cooling/filtering case fluid or just returning it to tank. Also depends if you are using open loop or closed loop. closed loop systems have loop flushing available.

but could the role of hydraulic pump or motor be reverse to recapture kinetic momentum as well as the pnematic pump and motor putting pressure back into the bottle when braking.

so maybe pneumatic would be better because an air bottle would replace the battery and the pneumatic pump is light and cheap to make an the pneumatic motor is also inexpensive . but there would have to be a gear to go from the pneumatic motor to the wheel. perhaps thats where the hydraulic motor/pump would come in. keeping the pneumatic at a constant speed but varying the torque and rpm to the weel without a heavy gear box.

i suppose the hydraulic motor would have to be put on the electric motor replacing the differential and transmission. there would still need to be a battery and and an engine and generator. all heavy and expensive. seems that just an engine and a hydraulic system would be great in cars .

couldn't a hybrid car use a hydraulic system and eliminate the need for a transmission still being used by hybrid auto? is the rpm high enough? is there too much heat lost ? what would be impractical about just putting a hydraulic pump on an engine and a hydraulic motor on an wheel axel? i notice most machines that actually do this are rather slow, would it be able to go from a stall and go all the way to 65mph? without using more gears? how is the torque to rpm varied with hydraulic

creo que esto no es un motor hidraulico, es una bomba hidraulica, uno de los engranajes es accionado por un vastago unido a normalmente el arbol de levas de un motor de explosion o diesel, haciendo girar al otro eng,. y de esa manera suministra presion hidraulica al sistema de lubricacion de dicho motor. no se debe confundir, no creo que oueda trabajar como motor hidraulico.

well i have used a lots of winches (PTO, electrics and Hydraulics, manuals) and in my opinion if you compare electric vs hydraulic, the hydraulic will beat a electric forever

@camilohrueda ..Hi .I got a question if you could help me out i'd appreciate it very much, I;m trying to get 80 foot pound of torque @ 1000 r.p.m on a hydraulic motor, what size or kind of pump do I need and what h.p electric motor do I need? thanks!

Question ,is a hydraulic pump the same as a motor? can they be switched ? specifically the Harbor freight pump.

Case drain is due to the relieved tolerances on the pump components so that some oil seeps through and acts as a lubricating media. After its lubrication purpose is achieved, the left over oil in the base of the pump has to be recycled and is sent back to the accumulator tank through filtering.
