What's the difference between an electric hydraulic and a pneumatic jack?

What's the difference between an electric hydraulic and a pneumatic jack?

Answer:

I mean, the final pneumatic or hydraulic still need electricity, please tell me the gas is supplied by the air compressor, the air compressor still needs electricity finallyChasing the answerHa ha, hydraulic, pneumatic, electric all need electricity.
The two are the same: the executing agencies are hydraulic piston rod. The difference between the two is: electric hydraulic motor drives the oil pump, so that oil into the hydraulic cylinder, push the piston rod to work. Pneumatic hydraulic jack is two cylinder: the smaller cross-sectional area of the cylinder and the area of the cylinder when the cylinder gas of large capacity into small capacity, will produce several times, even ten times of pressure on the small cylinder, the output of small cylinder piston rod increases greatly, this method is called "liquid booster". Also called the cylinder pressure cylinder.Here is a very simple introduction, the actual structure is more complex, the principle will not be repeated, please refer to the relevant information.
