Introduction to Hydraulic and Pneumatic Systems GH UNIT Syllabus: 1.1 General layout of oil hydraulics and pneumatic system. 12 Aplications, merits limitations of oil hydraulic and pneumatics system: 1.3 Properties of fluids,IS0 and SAE grades of oil. 14 ISO symbols used in hydraulic and pneumatic system. 1.5 Hazards and safety in Industrial hydraulic and Pneumatics. 1.1 Introduction of Fluid Power Block diagram of fluid power system After learning fluid mechanics and machinery in the fourth semester, students of mechanical engineering are able to know the use of fluids for power generation using turbines like pelton wheel, Francis, Kaplan turbines,ctc TOoperata various machines and PDerts Energy o ydrauile o pressëd 'air High Pressure USetud Tod low work Flg.1.1.1:8lock dlagramof Fluld powersystem DXefinison otiuid powersystem terhnology in uhieh weitruinsmi ar toforres andvelocities b trursmiting and CuTtaoLins PrESUre and lou offiuids . It means fluid possesses energy and we can utilize the energies offuids for various applications. In this course, fluid power can be used to operate various industrial machines and equipments, which is terimed as "Industrial hydraulics and pneumatics." Applications After various technical developments, from 1920 oil bydraulic emerged to operate industrial machinestools, material handling cquipments, mining equipments, etc. It has wide range of applications in various fields like automotive, agricultural uses, aircraft manufacturing, etc. In indastrialsector, the various machines, equipments were operated by using the power source of mechanical transmission, clectrical transmission, fluid transmissipn 1.1.2 Types of Fluld Power System: According to the nature or type of fluid used, it is systems. divided into two categories. Types of fluld power System eg. screwjack is mechanical operated device to lift the load Electrical motor is used to operate various machines using electrical power. Use of Incompressible 1.1.1 Fluld Power System Use ot compressible air It is the technology which deals withthe (gas) transmission energy by means ofenclosed pressurized fuids This technology is highly versatile power transmission system which utilize the energy of fuid (Oil, air, gas) toperformthe required workor task. eg Liting of very huge vehicles by using bydraulic crane, hydraulic press machine, etc. OUHydraulic system Pneumatic System Fig.1.1.2:Block diagram of types of fluld power system Scanned witn camScanner
