What are the differences between pneumatics and hydraulics? if possible give reply according to specification.

Hi Anita,
The differences between pneumatic and hydraulics are as follows:

a) Working fluid: Pneumatic use air, Hydraulics use Oil
b) Power: Pneumatic power less than hydraulic power
c) Leakage: Leaks in hydraulics cause fluid to be sticking around the components. In pneumatics, air is leaked into the atmosphere.
d) Pneumatic obtain power from an air compressor while hydraulics require a pump
e) Air is compressible, hydraulic oil is not.
Hope you understand.

Thanks
Ravi

Hi
this is Navjot
In pneumatic system we used compressed air to operate the pneumatic component like pneumatic cylinder. In hydraulic system the incompressible fluid (oil) is used.

Hi,
I;am Kamlesh
In Pneumatic system, a compressor is required to compress the air and a receiver to collect or store the air but in a Hydraulic system a oil tank is required so that a pump can easily transfer this oil to the cylinder with high pressure.
