Introduction To Fluid Power
Upon completion of this lesson students should be able to…
List at least three uses for fluid power. Understand how fluid power impacts
our daily lives. Compare and contrast hydraulic and
pneumatic systems. Identify the four main components of a
fluid power system.
A system that transmits and controls energy through the use of pressurized liquid or gas
Pneumatics - the media used is air Hydraulics - the media used is oil or
water
What is Fluid Power ?
Operation of heavy or hot materials
Unloading of hoppers in manufacturing, steel making, mining and chemical industries
What can Fluid Power Do ?
Crop spraying
Paint Spraying
Holding and
moving parts or
assemblies in
manufacturing
What can Fluid Power Do ?
More Fluid Power Examples Jig (guides cutting tool)
and Fixture (stationary work holding) clamping
Forming operations of bending, drawing and flattening
Bottling and filling machines
Machine tool changing
Component and material conveyor transfer
Robots Dentist drills vacuum lifting for
thin sheet materials
What can Fluid Power Do ?
Gases can be compressed Environmentally friendly and readily
available Pneumatic systems operate at lower
pressure compared to hydraulics Typically loud during loading and
operation Usually more economical
Pneumatic System Characteristics
Fluids are relatively incompressible Spills are not environmentally friendly
and readily available Hydraulic systems operate at higher
pressure compared to pneumatics Smooth predictable motion Oil lubricates and cools moving parts
Hydraulic System Characteristics
TankTank

ValveValve
The valve controls the amount of air or The valve controls the amount of air or fluid flowing throughout the system.fluid flowing throughout the system.
ActuatorActuator
The actuator does the work for the system The actuator does the work for the system by converting the fluid/air pressure into by converting the fluid/air pressure into either linear or rotational mechanical either linear or rotational mechanical movement.movement.
