Role of the Fluid Power Industry
Complete automation Speeds production Solutions Makes people more productive Makes production speed up Electro hydraulic and pneumatic systems enable complete automation Growth they grew 58% direct exports in 1997 were just under 1.3 billion Increases Productivity
4
Role of the Fluid Power Industry
Exports earned 1.3 billion 58% growth '92-'97

8
History of Fluid Power Breastwheel All wheels were used for drinking, irrigation, and drainage
9
History of Fluid Power Leonardo Da Vinci Wrote about nature of fluids
Sketches Drew sketches of pumps and hydraulic presses
10
History of Fluid Power Blaise Pascal Pressure on enclosed
fluid is equal in all directions Equal intensity on all surfaces Published results of experiments he made using syringes, siphons, bellows, and tubes Pascal’s law
11
Invented the hydraulic
History of Fluid Power Joseph Bramah Applied Pascal's law 200 years later Invented the hydraulic press Although fluid power came into use in the 18th century Most development has occurred in the 20th century
12
2 Types of fluid power systems
Hydraulics Pneumatics Physical Behavior Compression Density Pressure Hydraulics- Greek word for water & pipe Pneumatics- Greek word for wind, air, breath Expansion Uses gasses usually air Uses Liquids usually oil
13
2 Divisions of the Fluid Power
Hydrostatics Transfer of energy between components through a confined fluid Precise power and control Jacks, Backhoe Hydrodynamics Power created by water Kinetic energy of fluids Waterwheel
14
Applications of Pneumatics
Air Drills Jackhammers Doors on busses Tire changing machine Nail Guns Paint system
15
Applications of Hydraulics
Car lift Auto Jack Garbage truck Dentist Auto transmissions Heavy Equipment Airplanes
16
Air over Oil System Uses both hydraulics and pneumatics
17
Advantages of Fluid Power
Multiplication of force Easy, Accurate control Multifunction Safe
