1Hydraulic and pneumatic systems use fluid power. Technology Interactions
2Fluid PowerFluid power is the use of liquids or gases under pressure to move objects or perform other tasks.Any substance that flows is a fluid. Liquids and gases are both fluids.Fluids only have power when they are flowing.Fluids can be put under pressure and moved through pipes or hoses to where they are needed.
3Matter All objects are made of matter. The three states of matter are solidliquidgasThe state of matter is determined by how tightly its molecules are held together.
4Solids The molecules in solids are very strongly linked are hard to compressmaintain both their volume and shape
5Liquids The molecules in liquids are more loosely linked are hard to compressmaintain their volume but not their shape
6Gases The molecules in gases are very loosely linked are easy to compressdo not maintain either their shape or volume
7Hydraulic Systems Hydraulic systems use oil or another liquid. Liquids are very difficult to compress, so they can be used to transfer very powerful forces from one place to another.Hydraulic systems are ideal when high power and accuracy are required.
8Parts of a Hydraulic System A simple hydraulic system consists of:FluidPump-Provides pressure needed to move the liquid throughout the systemReservoir-Where liquid is storedRelief valve-Limits pressure in the system to a safe amount
9Parts of a Hydraulic System A simple hydraulic system consists of:Control valve-Directs liquid to the right locationSingle-acting cylinder-Transmission lines-Carry the liquid

11Pneumatic Systems Pneumatic systems use a gas, usually air. Pressure is built up by compressing the gas.Pneumatic systems can usually be lighter weight than hydraulic systems.The air they use is always available and since it is not a hazardous material, there is nothing to clean up.
12Parts of a Pneumatic System A simple pneumatic system consists of:Compressor-Squeezes the air/Draws air into the chamberReceiver-Stores the air from the compressorCheck valve-Allows pressurized air to enter the system/Prevents loss of air
13Parts of a Pneumatic System A simple pneumatic system consists of:Control valve-Directs air to the proper location/Regulates air flowActuator-Changes air pressure to mechanical motion
