Hydraulic and pneumatic components Flashcards
What is the primary function of a pump in hydraulic systems?
To create fluid flow by overcoming the pressure induced by a resistive load
Pumps convert electrical or mechanical energy into hydraulic energy.
What do compressors do in pneumatic systems?
Convert electrical or mechanical energy into pressurized air
Compressors can be categorized by the pressure they deliver: high, medium, and low.
What is the role of valves in fluid power systems?
Control the direction of the fluid
Hydraulic valves are actuated by liquids, while pneumatic valves are actuated by compressed air.
How is an AND circuit created in fluid power logic circuits?
By connecting two valves in series
This configuration allows for specific control of fluid flow.
How is an OR circuit created in fluid power logic circuits?
By connecting two valves in parallel
This arrangement allows for alternative paths for fluid flow.
What is the function of actuators in hydraulic or pneumatic systems?
Turn hydraulic or pneumatic energy back into mechanical energy
Actuators are essential for converting fluid power into movement.
What are cylinders in the context of hydraulic systems?
Actuators that use fluid power to force a piston to move in a certain direction
A piston rod moves back and forth within a barrel to create movement.
What is the formula to calculate the output force of a cylinder?
Force (F) = pressure (P) x area (A)
Area (A) is calculated as πr², where r is the radius of the cylinder.
Fill in the blank: A pump converts electrical or mechanical energy into _______.
hydraulic energy
True or False: Pneumatic valves are actuated by liquids.
False
Pneumatic valves are actuated by compressed air.
What types of energy do pumps and compressors convert?
Electrical or mechanical energy into hydraulic or pressurized air
Pumps deal with liquids while compressors deal with air.
What is the purpose of a pneumatic compact air cylinder?
To convert pressurized air into mechanical movement
These cylinders are commonly used in various automation applications.
