Hydraulic systems are very expensive. Hydraulic systems require special care. Thehydraulic system requires expertise.
Most hydraulic systems do not have accumulators.
Not usually. Hydraulic systems use fluids. Pneumatic systems use gas.
Liquid is used in hydraulic systems.
Air and hydraulic brake systems.
Hydraulic oil and hydraulic fluid are different. Hydraulic fluid is used in small systems such as car brakes. Hydraulic oil is used in large systems such as loaders.
Pneumatic systems use air or an inert gas. Hydraulic systems use water or oil.
there not...
both pneumatic & hydraulic systems are applications of fluid powers
Many principles are used in hydraulic systems the basic being the Pascal's law
By pressure.
Hydraulic systems are very powerful and flexible. Due to excessive speed and power are used in the excavation.
In large systems for cooling the hydraulic oil cooling is used.
