One uses a liquid, one uses air. not the same
BMW uses hydraulics for its brakes
it is because pneumatics is more flexible and easy to use rather than hydraulic[ebolton] There is no need to have a reservoir or return piping. The working "fluid", air, is non-toxic and non-flammable. Poster below is correct. Air systems typically have a tank that is the analog of a hydraulic reservoir.[ebolton]*****************Actually there is need for air reservoir in industrial pneumatics systems.Hydraulics can handle more powerful aplications than pneumatics for the same overall dimensions, or can be more compact for the same power.
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
Presses, earth moving equipment and farming machinery, hydraulics is used because it take up less space than the gears that is needed to produce the same power and if hydraulics is treated correct then there is almost no maintenance necessary
In an Automobile Pneumatics is used in tyres, breaks, suspension speed control and time delay
The brakes and steering are the standard applications for hydraulics in a car.
There are many differences, and here are a few: Pneumatic systems use gasses which are compressable - hydraulic uses liquids that are non-compressable. Hydraulics' motion is slow and smooth - pneumatics' motion is quick. Pressure can range from 500 to 5000 psi - pneumatics operate at around 100 psi.
Hydro means water or fluid. Hydraulics uses fluid compression to do its' work.
