The fluid power has been used from ancient period to till now in various form. In earlier day before development of technology the river flow is used to transport timber from upstream to down stream later followed by external, internal engine an turbines are as made use of fluid power and now we see earth movers and other instruments which make used of hydraulic power and thus we made our work economically easy fast.
Here the fluid is corresponds to the material which flows, which my be either gas or liquid. In hydraulics we makes use of properties of liquid to transfer power.
What is Hydraulics?
The hydraulics Is the Technology/science of make use of liquid, to transfer power through the liquid under the pressure. It makes use of properties of liquid such as density, viscosity, compressibility etc.
Why the name Hydraulics?
The word hydraulics is derived from the Greek word ”Hydra” means water and “aulic” means pipes.
How we can get work from liquids?
We can take/get the work from the liquid by setting an arrangement of various hydraulic components in sequential form to perform specific task.
The control system/ arrangement that controls OR transmits hydraulic fluid is known as HYDRAULIC SYSTEM
The hydraulic system makes use of Pascals law and continuity equation.
What is the basic idea behind the hydraulics?
Above fig. shows the basic idea behind the hydraulics that is when a force is applied at a point on the confined in-compressible fluid is transmitted to another point.
The major function of a hydraulic fluid is to provide energy transmission through system which enable work and motion to be accomplished easily with the less effort.
The fluid flows very easily with accuracy and flexibility by maintaining ability to transmit maximum power by weight.
