Hydraulic and pneumatic systems use fluid power. Technology Interactions ‹ Chapter Title Technology Interactions Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Fluid Power Fluid 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. Technology Interactions Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Matter All objects are made of matter. The three states of matter are ♦ solid ♦ liquid ♦ gas The state of matter is determined by how tightly its molecules are held together. Technology Interactions Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Solids The molecules in solids Technology Interactions ♦ are very strongly linked ♦ are hard to compress ♦ maintain both their volume and shape Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Liquids The molecules in liquids Technology Interactions ♦ are more loosely linked ♦ are hard to compress ♦ maintain their volume but not their shape Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Gases The molecules in gases Technology Interactions ♦ are very loosely linked ♦ are easy to compress ♦ do not maintain either their shape or volume Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Hydraulic 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.

Parts of a Hydraulic System A simple hydraulic system consists of: ♦ Fluid ♦ Pump-Provides pressure needed to move the liquid throughout the system ♦ Reservoir-Where liquid is stored ♦ Relief valve-Limits pressure in the system to a safe amount Technology Interactions Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Parts of a Hydraulic System • A simple hydraulic system consists of: Technology Interactions ♦ Control valve-Directs liquid to the right location ♦ Single-acting cylinder- ♦ Transmission lines-Carry the liquid Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Uses of Hydraulic Systems Manufacturing Transportation Construction Agriculture Entertainment industry Technology Interactions Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Pneumatic 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. Technology Interactions Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Parts of a Pneumatic System A simple pneumatic system consists of: ♦ Compressor-Squeezes the air/Draws air into the chamber ♦ Receiver-Stores the air from the compressor ♦ Check valve-Allows pressurized air to enter the system/Prevents loss of air Technology Interactions Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc. Parts of a Pneumatic System A simple pneumatic system consists of: Technology Interactions ♦ Control valve-Directs air to the proper location/Regulates air flow ♦ Actuator-Changes air pressure to mechanical motion Chapter 16 Hydraulics & Pneumatics Copyright © Glencoe/McGraw-Hill A Division of The McGraw-Hill Companies, Inc.
