ABSTRACT
Hydraulic systems are designed to transmit energy and apply large forces with a high degree of flexibility and control. Water and many other liquids can be utilized to make practical use of Pascal’s Law, which states that a fluid compressed in a closed container will transmit the resulting pressure throughout the system undiminished and equal in all directions. Hydraulic systems provide a significantly more accurate and adjustable means to transmit energy than electrical or mechanical systems. In general, hydraulic systems are reliable, efficient, and cost effective, leading to their wide use in the industrial world. They are part of a major technical discipline called fluid power technology. A typical hydraulic system includes the following components [1]:
1. A fluid flow or force-generating unit that converts mechanical energy into hydraulic energy, such as a pump.
