Overview
This is the branch of physics or technology concerned with using pressurized gases to produce mechanical movement.
What is pneumatics?
What are the pipes in pneumatic ciruits usually made of?
Steel or brass, or polyethylene and polyamide.
Which type of valve allows the air to flow in one direction only?
Non-return valves.
Give an example of a device that might use a hydraulic circuit.
Forklift trucks or platform lifts.
Which city or state is Marina from?
Any ONE is sufficient:
City:Portland
State:Oregon
This is the use of liquids, such as mineral oil, pushed through pipes and channels to produce mechanical force.
What is hydraulics?
What are rotary actuators?
The motors that produce the rotating movement of an axel.
Name 3 types of directional control valves, and what their numbers represent.
2/2, 3/2, 4/2, 5/2. The numbers stand for the number of ports and positions.
These two protection and maintanence elements of a hydraulic circuit serve the same purpose as the pressure relief valve in pneumatic circuits.
At what age can you take your driving test and get your license in the U.S.A.?
You can take your driving test and get your license when you are 16 years old.
What are the control elements in pneumatic and hydraulic circuits?
Valves.
Describe a rotary compressor.
These are made up of a compression chamber and a rotor. When the rotor rotates, the compressor sucks in the air and compresses it in the chamber.
What is the AND function and type of valve carries it out?
When air is only allowed to flow out when two inputs are active; dual-pressure valves.
Do hydraulic circuits create more force than pneumatic circuits? Why or why not?
Yes they do, because they can work at higher pressures.
Does Marina have any siblings? If so, how many?
Yes, Marina has two younger sisters.
What are the transport elements in pnuematic and hydraulic circuits?
Pipes.
Which compressor uses a crankshift mechanism with cooling fans around the piston to keep the air temperature of the circuit down?
Reciprocating compressors.
What is the OR function and which type of valve carries it out?
When their is an output of pressurized air at a certain point if air enters either of the two inputs; shuttle valves.
What is the purpose of a reservoir?
To collect liquid once it has passed through the whole circuit in order to reuse it.
What are the names of each year in American high school?
1. Freshman, 2. Sophomore, 3. Junior, 4. Senior
What is the actuator in pnuematic and hydraulic circuits?
The cylinder.
Name and describe the two types of reciprocating actuators.
Single-acting and double-acting cylinders.
Name at least 3 elements that protect pneumatic circuits from overpressure and help them last longer, and briefly describe their function.
Air dryer, filter, conditioning unit, lubricator, pressure relief valve, silencer.
What is Pascal's Law?
The idea that when a force is applied to a liquid in a closed container, the pressure is transmitted equally throughout the liquid regardless of the shape of the container.
What did Marina study at university?
Any ONE is sufficient:
Marina studied Environmental Science and Spanish Literature.
