Introduction to Pneumatic

What are the main components of a pneumatic system?

• air compressor, air reservoir, pneumatic cylinder, directional control valves, air hoses

• hydraulic cylinder, air hoses, pressure gauge, solenoid valves

• piston pump, air hoses, pressure regulator, check valves

• electric motor, air hoses, pressure switch, flow control valves

Explain the difference between a single-acting and double-acting pneumatic actuator.

• Double-acting actuators are slower than single-acting actuators.

• In a single-acting actuator, air pressure is applied to one side of the piston, while in a double-acting actuator, air pressure is applied to both sides of the piston.

• In a single-acting actuator, air pressure is applied to both sides of the piston.

• Single-acting actuators are more energy-efficient than double-acting actuators.

Draw and explain the symbol for a 3/2-way pneumatic valve.

• A circle with two arrows pointing in opposite directions

• A triangle with a line connecting two corners

• The symbol for a 3/2-way pneumatic valve is a rectangle with an arrow pointing towards the outlet port and a diagonal line connecting the inlet and exhaust ports.

• A square with a line connecting opposite corners

How does a pneumatic control circuit work?

• A pneumatic control circuit works by relying on gravitational forces to control devices.

• A pneumatic control circuit works by using compressed air to control the operation of various pneumatic devices such as cylinders, valves, and actuators.

• A pneumatic control circuit works by using hydraulic fluid to control devices.

• A pneumatic control circuit works by utilizing electromagnetic fields to operate devices.
