Mechanica , pneumatic and hydraulic Flashcards
What is use of push button operation?
Can be pushed to turn the circuit on
only stays on while pressed
What is function of lever operation?
Can be used to turn the circuit on
stays on until turned off
Function of 3-port valve
Used to activate different parts of the circuit
Function of 5 port valve
Its controlled by a single button
Function of shuttle valve
Can be used as ‘or’ gate to activate the circuit in response to
two connected inputs
Function of single acting cylinder with
spring return
Turns air pressure into linear force of movement when
oressure is applied
Function of double acting cylinder
Turns air pressure into linear force of movement
used to open/close cylinder
Function of the reservoir?
Used to hold the gas (pneumatic) or liquid (hydraulic) system
Function of flow regulator/unidirectional flow of control valve
Used to control the amount of gas/liquid flowing
allows it to flow in one direction only
Function of pipes
(straight thick line)
Allow the gas or liquid to flow round the system
Function of mains air suppy
Shows the location of the pump used to power pneumatic system
Function of exhaust air
Allows the gas in pneumatic system to escape
removing pressure
What is pneumatic system?
System powered by air pressure
What is hydraulic system?
System that uses fluid to transmit power
What are mechanical parts?
Parts used in moving equipment/machinary
Uses of threaded fixers
- Screws
- Nuts
- Bolts
Use of non-threaded fixers
Split pins
Circlips
wire rings -hold components in place
Use of springs
A coil/metal
often used to allow movement within device
Use of bearings
Can be metal/plastic
used to hold rotating part in place but moves
Use of gears
Made from metal/plastic
used to change speed/torque of motor
Use of belts and pulleys
Used to join moving parts
