Construction (Pneumatics)

Question 1

What are discrete components in a pneumatic system?

Answer 1

Individual components such as cylinders, valves, actuators, and regulators that are assembled to build a pneumatic circuit.

Question 2

What is the process of designing a pneumatic system?

Answer 2

Deciding on the function required, selecting appropriate discrete components, arranging them logically in a circuit, and ensuring correct connections and control.

Question 3

What should be included when drawing a pneumatic circuit diagram?

Answer 3

Symbols for all components, clear connections showing airflow paths, pressure sources, exhausts, and control inputs.

Question 4

Name three key components you might use when constructing a pneumatic system.

Answer 4

Single Acting Cylinder (SAC), 3/2 Valve, and Shuttle Valve.

Question 5

What is important to consider when constructing a pneumatic system?

Answer 5

The correct sequence of operations, appropriate speed control, safety features, and ensuring there are no leaks in the system.

Question 6

How do you analyse a pneumatic circuit diagram?

Answer 6

By following the airflow paths, identifying the input, process, and output components, and checking how control valves and actuators interact.

Question 7

Why is it important to test a pneumatic system after construction?

Answer 7

To ensure it functions as intended, there are no air leaks, and the sequence of operations works safely and reliably.

Question 8

Give an example of a basic pneumatic system operation.

Answer 8

A push button (3/2 valve) controls the movement of a single acting cylinder to extend and retract.

Question 9

How can a pneumatic system be modified for added safety?

Answer 9

By adding an AND circuit requiring two control buttons to be pressed together before the cylinder activates.
