  1. Hydraulics Term 2 science due 1/10/13 By Drew Perry

  2. Intro To Hydraulics • Hydraulics are a liquid form of pneumatics • Pneumatics are when pressurized gasses are used to produce mechanical rotation. • They are used for the generation of control , and transmission of power through fluid.

  3. Common use • Hydraulics can produce huge amounts of power making them great for construction equipment, like excavators, skid-steer, and bulldozers. • Shocks , weather it be on a car or bike. • Mechanics tools like floor jacks or lifts.

  4. History time • There has always been a need for a transmission of power to make greater force • The invention of the steam engine created a spark that began the base hydraulics as we know it. • Steam pushed pistons like oil does in hydraulics.

  5. Power • Hydraulics pistons get their power from pressurized oil being pushed against a cylinder • They can exert tens of thousands of pounds of force. • Lines or hoses that contain hydraulic oil are under so much pressure that they burst. .

  6. Hydraulic Pumps • The hydraulic fluid is controlled by a pump that continuously rotates pushing fluid through the line in a cycle. • There size varies ,depending on how much pressure is needed for the task at hand.

  7. Hydraulic Fluid/oil • Hydraulic power is transferred through a medium which would be based off mineral oils or water . • Most mineral oils are a by-product of the distillation of petroleum to make gasoline. • It is most commonly sold in 5 gallon buckets with an average cost of:100$ to 135$

  8. Hydraulic Fun in cars • All work and no play make for a dull day • Starting mid 1970s people found out that adding bigger or more batteries to power the hydraulics in there low-rider's to get the wheels off the ground • This is caused by a jolt of electricity making the pump pressurize and extend the hydraulics in the suspension.
