ATCHM501-PERFORM HYDRAULIC STYSTEM MAINTENANCE
Introduction
Hydraulic systems are power-transmitting assemblies employing pressurized liquid as a fluid for transmitting energy from an energy-generating source to an energy-using point to accomplish useful work. The figure shows a simple circuit of a hydraulic system with basic components. Hydraulic systems are used for transmission of power through the medium of hydraulic oil. The hydraulic system works on the principle of Pascal’s law which says that “ the pressure in a fluid at rest is transmitted uniformly in all directions”.
The fluid medium used is hydraulic oil, which may be mineral oil or water or combinations. This area is also known as oil hydraulics.
