Millwright Level 3 Flashcards
What is a pneumatic system?
A pneumatic system uses compressed air to transmit and control energy.
True or False: Pneumatic systems are typically more efficient than hydraulic systems.
False
Fill in the blank: Pneumatic systems primarily use __________ as their working fluid.
air
What are the main components of a pneumatic system?
Compressor, reservoir, actuator, and control valves.
Multiple Choice: Which of the following is NOT a common application of pneumatic systems? A) Material handling B) Automation C) Water treatment D) Packaging
C) Water treatment
What is the purpose of a compressor in a pneumatic system?
To convert mechanical energy into potential energy by compressing air.
True or False: Pneumatic systems can operate at high pressures.
True
What is the function of a pressure regulator in a pneumatic system?
To maintain a constant output pressure regardless of variations in input pressure.
Fill in the blank: The __________ is used to store compressed air in a pneumatic system.
reservoir
Multiple Choice: Which type of actuator converts pneumatic energy into linear motion? A) Rotary actuator B) Pneumatic cylinder C) Hydraulic pump D) Electric motor
B) Pneumatic cylinder
What is a common safety measure for pneumatic systems?
Using pressure relief valves to prevent over-pressurization.
True or False: Pneumatic systems are less clean than hydraulic systems due to the use of oil.
False
What does the term ‘cubic feet per minute’ (CFM) measure in pneumatic systems?
The flow rate of air through the system.
Fill in the blank: __________ valves control the direction of airflow in a pneumatic circuit.

B) 30-100 psi
What does the term ‘actuation’ refer to in pneumatic systems?
The process of moving a component using pneumatic energy.
True or False: Pneumatic systems can be used for both static and dynamic applications.
True
What is the significance of maintaining proper lubrication in a pneumatic system?
To reduce wear and tear on components and ensure smooth operation.
Fill in the blank: The __________ is the point where the compressed air is released for use in a pneumatic system.
outlet
