  1. Hydraulics- fluid power for the massesMatthew R. Bono

  2. Hydraulics • General Information • (14.4 MB) – Matthew Bono • CLF 2900.  Work and Power • CLF 2912- Uses for Work and Power

  3. Other Applicable Standards • California Agriculture Mechanics Pathway Standards • B11.0: Students understand the principles and applications of various engines and machinery used in agriculture • B11.4- Know the theory and operation of mobile hydraulic systems and power take-off systems

  4. Energy transmitted and controlled by means of a pressurized fluid, either liquid or gas. Technical Description

  5. Common Description • Fluid Power • Doing work using transmitted fluids or gasses

  6. Work and Power • What are Work and Power • Work • Using force to act on an object over a distance. • Pushing a car up a hill • Power • The rate at which work is performed • Pushing a car up a hill faster than someone else

  7. Work and Power • In Hydraulics • Hydraulic systems are a way to do work and use power to move or stop objects. • The systems can increase, speed, power, and are maneuverable

  8. Common Examples of Hydraulic Systems • Automobile Brakes • Heavy Machinery • Airplanes • Trains

  9. Common Examples • Automobile Brakes Hydraulic Fluid Pressurized by foot pedal and booster closes piston, slows rotor and wheel

  10. Common Examples • Heavy Machinery

  11. Common Examples • Airplanes • Planes use hydraulics to fly, land and steer Red Lines and Blue Lines control different surfaces using different systems but same control lever

  12. Common Examples • Trains • Trains stop, or not, using air brakes, which are considered hydraulics also

  13. Other Common Examples • Trains • Where else could we use hydraulic power? • Thinks outside the box.

  14. Principle of Transmission of Fluid-Pressure “Where there is an increase in pressure at any point in a confined fluid, there is an increase at every other point in the container.“ Theory- Pascal’s Law

  15. Theory Demonstrated Key F1- Force 1 F2- Force 2 A1- Area 1 A2- Area 2 Blue area is fluid acting on both pistons in the closed system

  16. Theory Explained Hydraulic System typically fluid is pumped into a confined space in order to make something move. This movement can be to turn a motor or extend or retract a ram or piston. Moving either piston in the picture would move the other. F1= Force 1 F2= Force 2 A1= Area 1 A2= Area 2

  17. Theory Explained If F1=F2 the System has No Movement In Real life these systems usually involves movement The F1=F2 pistons are connected by the same fluid If the fluid moves equally, piston 1 moves further but with less force due to less surface area F1= Force 1 F2= Force 2 A1= Area 1 A2= Area 2

  18. Parts of a Closed System Reservoir Filter Pump Valve Cylinder Lines

  19. How It Works • Motor Spins Pump • Pump Moves fluid • a. Out of reservoir • Through filter • Through Pump • c. Into valve • Valve directs fluid to ram • Pressurized side of ram moves • Fluid on other side of ram returns to reservoir

  20. How to Power the System Elbow Grease- like a automotive jack Electric Motor Fueled Motors gasoline, diesel, aviation anything else System Design Flow Rates Pressures Location Point of Action What can change

  21. As motor power goes up the pump has more power to move fluid This can increase flow rate or pressure How it worksHorsepower, Flow Rate and Pressure

  22. How it works Flow Rate Hydraulic systems rely on filling a given area with fluid The more fluid you pump into the area the faster the implement moves If your trying to float a rubber boat in a swimming pool what will do it faster a garden hose or a fire hose

  23. How it works Pressure Hydraulic systems like the jaws of life can create incredible amounts of force What shoots further, water from a hose spraying a cone or spraying a jet

  24. Advantages • Force Multiplier – • Automobile Brakes • Controllable- • variable speed and power • High power low weight- • Especially air powered • Very Mobile- • Harvesting Equipment • Possibilities- • Diesel Hydraulic Hybrid Delivery Trucks • Roller Coasters

  25. Force Multiplier – Automobile Brakes • The force of your foot can stop an entire car, with help from hydraulics

  26. Controllable- • Large harvesting equipment can do dozens of things at one time all with hydraulic power

  27. Controllable- Cotton Picker Header Each row of cotton goes through the picking zone Each spindle moves independently of the others while machine moves through field, blows lint into hopper and discards waste

  28. High power low weight

  29. Very Mobile • The jaws of life in the last slide are used by hundreds of rescue outfits across the US and are readily carried everywhere they go

  30. Possibilities- Diesel Hydraulic Hybrid Delivery Trucks • This truck showed a 60To 70% increase in fuel economy and reduced emmisions by more than 40% and could reduce costs to consumers and companies while reducing the pollution.

  31. Why does it Matter Hydraulic systems are in everything from aircraft to theater performances in Las Vegas. Someone had to design, build and maintain all these systems, why couldn’t it be you?
