Pneumatics

Question 1

Advantages

Answer 1

Availability
Elasticity
Safety
Easy selection of speed and force
Reliable
Low installation and maintenance cost

EXPENSIVE

Question 2

Circuit and symbols

Answer 2

Cylinders drawn to show their extreme or intermediate stroke positions

Cylinders drawn to show any length above their width

Cylinder symbols are not indicative of their actual size * Valves show all states in the one symbol

Prevailing/ Most Usual state is shown with the port connections

Question 3

Basic Valve symbols

Answer 3

Show all possibilities
Right: normal state
Left: Operated State
Port 1 on the left
Straight line: flow path with the arrow being the direction the fluid flows
External piping connected to valve: straight lines outside of box
Work port above square, power and exhaust below square

Question 4

System Design Protocol

Answer 4

Actuators: orientation, loading, guidance, forces

Valves: correct flow to suit needs

Tube: minimum diameter and length to suit the flow required

Air Preparation: optimum port to suit flow required

Question 5

Pneumatic components required to control the quality of a compressed air source

Answer 5

Water filter to capture moisture generated

Particle filter to capture contaminants

Pressure regulator

Pressure guage
