What is the main cleanliness advantage of pneumatic systems over hydraulic systems?
Answer: No risk of fluid leaks or oil contamination
Pneumatic systems use compressed air, eliminating the risk of oil leaks and fluid contamination that are common concerns in hydraulic systems.
In a pneumatic system, what is the purpose of an air dryer?
Answer: To remove moisture from compressed air
An air dryer removes moisture from compressed air to prevent corrosion, valve damage, and freeze-up in cold conditions.
What unit is most commonly used to measure pneumatic pressure in the United States?
Answer: PSI (pounds per square inch)
In the US, pneumatic pressure is commonly expressed in PSI (pounds per square inch), representing force per unit area.
Which component in a pneumatic circuit regulates airflow to control actuator speed?
Answer: Flow control valve
A flow control valve restricts the volume of air per unit time passing through the circuit, directly controlling actuator speed.
What does the acronym FRL stand for in pneumatic conditioning units?
Answer: Filter, Regulator, and Lubricator
An FRL unit combines a Filter (removes contaminants), Regulator (sets working pressure), and Lubricator (adds oil mist) in one assembly.
A double-acting pneumatic cylinder uses compressed air to:
Answer: Both extend and retract the piston rod under power
A double-acting cylinder applies air pressure alternately to both sides of the piston, providing powered force in both extend and retract directions.
