1, why is water not used in hydraulics ?

Even the presence of water in hydraulic oil will damage the system components.

Also the water molecules will result in oxidation/corrosion of metal surfaces. The low boiling point and freezing point of water is another drawback of using water as a hydraulic fluid.

2, why liquid is used in hydraulics ?

Common hydraulic fluids are based on mineral oil or water.

Examples of equipment that might use hydraulic fluids are excavators and backhoes, hydraulic brakes, power steering systems, transmissions, garbage trucks, aircraft flight control systems, lifts, and industrial machinery.

3 How do you build a piston hydraulic cylinder?

For the design of hydraulic cylinders, speed and power must be calculated in dependence of the existing pressure in the cylinder space and the volume flow available.

4, what is function of cylinders ?

The cylinder is the space through which the piston travels, propelled to the energy generated from the combustion of the air mixture in the combustion chamber.

In an air-cooled engine, the walls of the cylinders are exposed to the airflow, to provide the primary method of cooling to the engine.
