INTRODUCTION TO PNEUMATIC

What is the type of positive displacement of compressor?

• Centrifugal compressor

• Screw compressor

• Vane compressor

• Single acting compressor

What is the type of dynamic compressor

• Single acting compressor

• Centrifugal compressor

• Double acting compressor

• Rotary compressor

What is the single stage compressor?

• It work on the principle of air filling the void between two helical mated screws and their housing.

• It consist of a rotor with a number of blades inserted in radial slots in the rotor.

• The air compressor is single acting when the compressing is accomplished using only one side of the piston.

• The air compressor is single acting when the compressing is accomplished using two side of the piston.

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

What is advantages of pneumatic

• Easily extended for long distances and easily stored. That reliability infinite.

• Air is not subject to temperature and non-flammable.

• Air does not require a back-flow.

• Simple pneumatic system components constructed when compared to other systems.

What is disadvantages of pneumatic system?

• Can provide a rapid response to start and stop control

• It uses a lot of pipes

• Compressed air systems require careful preparation.

• Necessity forces are limited, only 20 kN - 30 kN.

Typical pneumatics applications include:

• Cylinders

• Vacuum pumps

• Cable jetting

• Air brakes

Sort the signal flow from start until end.
