Fluid Power

A WebQuest for Technology Education

What Is Fluid Power

• Energy controlled by the use of pressurized fluid (liquid or gas).

• This can relate to both hydraulics and pneumatics.

Hydraulics

• Uses pressurized liquid

• Many types of liquid can be used

• Hydraulics can be found in many places.

• Use this website to find two types of liquid and 5 uses for hydraulics.

• http://science.howstuffworks.com/transport/engines-equipment/hydraulic.htm

Pneumatics

• Uses compressed air or gas to transfer energy.

• This also uses many types of gasses

• There are also many uses of pneumatic technology.

• Use this website below to find 2 types of gases and 4 uses of pneumatics http://www.eng.iastate.edu/twt/Courses/Undergrad/packet/info/pneumaticsinfo.htm

How Does Fluid Power Work?

• Pascal’s Law:– “Pressure exerted by a confined fluid acts

undiminished equally in all directions”• Who is Pascal? Find 5 facts about him here:

– In other words, no pressure is lost when transferring it through fluid power technologies.

What Are Some Advantages?

• Easy to control/Easy power transfer

• Always a constant force

• High amount of force for it’s low weight.

• Quick response

What are some Disadvantages?

• Possible fire/explosive hazard for some liquids

• Must not contain any outside debris

• Difficult to clean up
