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.

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.

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.

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. .

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.

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$

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.
