yes, the pump is what pressurizes the canisters, without any pressure nothing would move
That pump operates the pneumatic central door locking system.
Yes there is. Pneumatic valve springs. They are metal bellows that have air in them. Their use is in replacing metal wire springs in a high-speed combustion engine. An example would be formula one engines.
Pneumatic. Pneu = Air. Hydra = liquid
Usually ordinary air is used in a pneumatic system.
both, if it pumps liquid then it's hydraulic, if it pumps gas it is pneumatic
it is a bike operated by air
Difficult question to answer without context. Key thing to understand is a pneumatic system uses a compressor, whereas a hydraulic system uses a pump. Hydraulic fluid is essentially incompressible, whereas compressed air will fill any volume. Ask yourself: What is my pneumatic/hydraulic system supposed to do? How fast should it react and what horsepower is available to drive my compressor/pump? What force do I need at my actuator/motor or whatever the system is expected to power? Generally, I think pneumatic systems can react more quickly but power density is lower, so if the load is very high a hydraulic system might be better. A typical shop pneumatic system might only operate at 50psi, whereas a hydraulic system can operate at 3000psi. Finally, it's also worth thinking about system safety: if a pneumatic component fails, there will be an explosive decompression, but if a hydraulic component fails, it will leak but will not explode because hydraulic fluid does not store energy, it only transmits it.
The pneumatic system controlled by electronic systems.
Pneumatic braking system utilizes compressed air to stop the motion in vehicles.
Sand blasting uses air pressure as an ejector within the blasting process. This is how the pneumatic system is used in a pneumatic sand or paint blaster.
both pneumatic & hydraulic systems are applications of fluid powers
human respiratory uses air pressure like pneumatic system does
