Why it is important to be sure that there is no air in the telemotor system?

Hydraulic systems work because liquids are, for all practical purposes, incompressible. When you apply pressure to the master cylinder in a hydraulic system, that pressure is transmitted equally throughout the system.Gases, however, are extremely compressible. When you put pressure on the master cylinder in a hydraulic system in which there is air in the lines, all that happens is that you compress the air in the lines; the pressure is NOT transmitted to the working cylinders.


Is a hydraulic jack a hydraulic or pneumatic system?

Hydraulic , the jack uses fluid under pressure to raise the cylinder , releasing the pressure allows the cylinder to retract. Pneumatics is a similar concept using air pressure.


Do hydraulics depend on air pressure?

Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.


Why we don't use high pressure in pneumatics?

one reason air is much harder to control the heat and air has a lot of water in it and a hydraulic system dose not need water in the hydraulic oil. There is no way at the high pressure that a hydraulic system has to work at,it would not be possible to control the heat.


What kind of pressure is developed in a semi truck hydraulic brake system?

Semi trucks have air brakes, no hydraulics some very old trucks had air over hydraulic systems but they used no more pressure than any other system


Do hydraulic systems depend on air pressure?

Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.


Why hydraulic breaks known as hydraulic?

Because they are actuated by fluid pressure, rather than pneumatic (air) pressure.


Why will a cars braking system not work well if air gets into the brake fluid?

Air will compress under pressure, hydraulic brake fluid doesn't. Air in the system will give you a spongy peddle because of that.
