Like what machines uses hydraulics/pneumatic systems?
Hydraulics is backhoes and excavators you see doing road work. Those digging arms are all all hydraulic power Pneumatics is what you see when you get your tires changed on the tire machine. The pneumatic cylinder pushes the bead off the tire rim and tires the pedestal that pulls the tire off the rim. Pneumatics is also the thing that runs all the air tools in a shop-- the grinders, the air hammers, the torque impact wrenches etc. Pneumatics are usually a lot weaker than hydraulics, but are cheaper since most of them just get their power from a shop air compressor and that air compressor is used to run all the air power requirements in a shop. Hydraulics involves running a pump that pumps an oil under pressure that moves a cylinder. In these systems the oil pushes the cylinder with more than 2000 psi. After it moves the cylinder the oil then returns to the pump thru a separate line. The reason shops like pneumatics is you don't need a return line. The air pressure comes from the air compressor , it runs the tool and the air is exhausted out to the room. Also the pressures are a lot lower (about 100psi) so if a air line blows up there is very little danger to someone near it
hydraulic: car break system Pnumatic :trucks break system and bus automatic door
Hydraulics: Water pump. Pneumatic: Air compressor out put used for spray painting etc.
