                                             BASIC OF HYDRAULIC SYSTEM






                       Learning Outcomes:    Apply the basic concept and function of hydraulic system.



                       This  topic  gives  exposure  and  understanding  on  the  standard  symbol  for  hydraulic


                       components, introduction to basic components of hydraulic and pump, valve and actuator.



                       In  1795,  Joseph  Bramah,  an  engineer,  invented  the  first  hydraulic  press.  This


                       demonstrated that a low force, acting over a long stroke, on a small diameter piston could


                       develop a pressure in a fluid on contact with the piston. A hydraulic system uses a fluid



                       under pressure to drive machinery or move mechanical components. The power of liquid


                       fuel in hydraulics is significant and as a result, hydraulic are commonly used in heavy


                       equipment. That pressurized fluid acts upon every part of the section of a containing



                       vessel and creates force or power so it can lift heavy loads.
