Pneumatic Circuits - Practice Test

Front

What is a pneumatic flow control valve?

Back

A device that regulates the flow of compressed air in a pneumatic system, often containing components like check valves.

Front

What is the function of a regulator in a pneumatic circuit?

Back

To control and maintain the pressure of the air supplied to the system, ensuring consistent operation of components.

Front

What happens to air pressure as it flows through a pneumatic system?

Back

Air pressure drops due to friction resistance and other factors as air moves through the system.

Front

Why is it important to secure devices or hoses containing compressed air?

Back

To prevent the item from whipping, which can cause injury or damage.

Front

Which type of cylinder does not require air pressure to extend?

Back

Cylinder B, which may be a spring-return or gravity-operated cylinder.

Front

What is the role of a check valve in a pneumatic system?

Back

To allow air to flow in one direction while preventing backflow, ensuring proper operation of the system.

Front

What is the purpose of a filter in a pneumatic circuit?

Back

To remove contaminants from the compressed air, protecting components from damage and ensuring efficient operation.

Front

What is a lubricator in a pneumatic system?

Back

A device that adds a small amount of lubricant to the compressed air to reduce friction and wear on moving parts.

Front

What is a directional control valve?

Back

A valve that directs the flow of air to different parts of the pneumatic system, controlling the movement of actuators.

Front

What is the impact of air friction resistance on actuator speed?

Back

Air friction resistance can decrease actuator speed by reducing the effective pressure available for movement.
