easy: Both use pressure now hydrolics used liquids (liquids cannot be compressed) to exhert pressure pneumatics uses gasses which are compressed to exhurt pressure thtas the basics anyway
what are the similarities between basketball and ring-ball
what is the similarities between the ulna and the radius
similarities
what are the similarities between network switch and a hub
There are zero similarities between the two.
In hydraulics. Power is transmitted through the air. The pneumatic. Power is transferred by the oil.
Hydraulics use liquids as the working fluid, pneumatics use gases as the working fluid.
oil is slightly compressible 0.5 % at 70 bar. but air is compressible. so to get the required pressure pneumatics require more energy source than hydraulics also there are some limitations for pneumatics in terms of force.
My thoughts go like this...(from watching 'Scrapheap Challenge"0 plus a little basic knowledge of physics. 1/ Pneumatics involve the movement of pistons and what not via the medium of compressed air or air under pressure. 2/ Hydraulics involve the movement of pistons and what not via the medium of compressed fluids or fluid under pressure. 3/ Fluid is denser than gas (compressed air). I believe hydraulics can handle far heavier loads than pneumatics. Pneumatics would appear to use a lighter more flexible medium than hydraulics. In answer to your question, I believe hydraulics would be far more effective at manipulating heavy loads versus pneumatics. However, pneumatics would be a more flexible system than hydraulics. Hows that?
Hydraulics is the use of liquids to transmit power. Pneumatics is the use of gases (usually air) to transmit power.
BMW uses hydraulics for its brakes
One uses a liquid, one uses air. not the same
Basically pneumatics deal with lower loadings, hydraulics offer a better power to space ratio, useful in say aircraft design.
Pneumatics have the advantage over Hydraulics in that they are clean, require lower maintenance and respond quicker. When the application does not require that much force, pneumatics will do the job. Furthermore: the force needed for train doors should not be that large. It should only open and close the doors but not crush people that manage to get stuck in between
It is extremely essential in Hydraulics and mechanics. Your car would not run without pneumatics.
Fluids are used in Hydraulics - fluids are essentially incompressible - they transmit forces well (e.g. a car bottle lack) Gases are used in pneumatics - gases are compressible - you can therefore store energy in a pneumatic system (e.g. a car tyre)
hydraulic is liquid based, pneumatic is air.
