BASIC OF HYDRAULICS

  • 1. Definition

The steady of hydraulics deals with the use & characteristics of liquids.

The term “Hydraulics” has been derived from 2 greek words

  • “Hydor” -> meaning Water

  • “Aulos” -> meaning Pipe

Therefore the term “Hydraulics” can be broadly defined as the work done by fluids in pipes.

  • 2. Classification

Hydraulics is broadly classified into 2 types

  • HYDROSTATICS

  • HYDRODYNAMICS                              

3. Pressure

Pressure is defined as the force exerted over an unit area of cross section.

Pressure  = Force/Area [force in -  kilograms (kgs),  Area in  - (cm2),  Pressure is in – (kg/cm2)]                                        

Atmospheric air exerts an uniform pressure all around us. At sea level the atmosphere air
exerts a pressure of 1.03322 kgf/cm2.             

    • 4. Pascal’s Law

    Pressure applied on a confined fluid is transmitted undiminished in all directions & acts with equal force on equal areas & at right angles to them. Pascals was a French Scientist who discovered this in the 17th Century.

  1. 5. Bernoulli’s  Principle

The sums of the pressure energy & kinetic energy at various points in a system is constant if flow rate is constant. When the cross-sectional area of flow path increases, the velocity (kinetic energy) decreases, & results in the increase of pressure energy , pressure. This transformation of energy from one type to the other keeps the sum of the two energies constant. Venture effect in a gasoline engine carburetor is an application of the Bernoulli’s Principle

 

  • 6. Hydraulic power transmission

The source of power for the hydraulic system is the prime mover which may be an electric
motor or an engine which will drive the pump. The pump is called the input component in a hydraulic system. The output component in a hydraulic system is called the actuator.
There are two types of actuators -

  • 1. Linear actuators -> (cylinder) which give linear motion along with force.
  • 2. Rotary actuators -> (Hyd. Motors) which give rotary motion along with torque.
