What is screw compressor?
It is a type of rotary compressor which compresses air due to screw action
It use a centrifugal motion to generate compressed air rather than the reciprocating motion of the compressor piston pump
It use the impeller to furnish rotational pressure, which squeezes the gas outward and closer together, resulting in some pressure increase.
It is a type of rotary compressor which compresses air due to vane action
What is rotary vane compressor?
It has a crankshaft, a connecting rod and piston, a cylinder and a valve head
It applies mechanical force to gas to increase its velocity, which is the converted to pressure
It work on the principle of air filling the void between two helical mated screws and their housing.
compressors consist of a rotor with a number of blades inserted in radial slots in the rotor.
What is the function of filter
A component that monitors gas passageways in a pneumatic system in order to maintain a consistent pressure level.
should be fitted to reduce pressure fluctuations.
remove the contamination from atmospheric air
reduce the moisture content in air
Name the type of directional control valve pictured ?
5 way 2 position
5 way 5 position
2 way 5 position
3 way 2 position
With regards to safety what should you NEVER do with pneumatic hoses ?
Reduce the pressure to zero when commencing work on a pneumatic system.
Inform your supervisor when work is about to commence
Put up barriers around the work area when working on pneumatics.
