Air Compressors and it's types?

Introduction:-

The primary objective of employing a compressor is to provide high pressure air using least possible power consumption. And it's primary function is to suck the atmospheric air,compress it as per our requirements and it deliver the same at high pressure.

                            Air compressor

Air compressor:-

Air compressor is a Mechanical device that increases the pressure of a gas by reducing it's volume.An Air Compressors is a specific type of gas compressor.

                                     It can be also defined as an "Air Compressors is a device which enhances the air pressure at least three times higher than that of atmospheric pressure.thus compression ratio for Compressors is more that three.

Advantages:-

• They tend to be less expensive

• Upgrading permanent mount compressors with air filters, water filters, and in-line lubrication is easier.

• There is a much broader selection of electrical power options for mounted units.

• Generally, they are more powerful.

• Generally ,they have greater air capacity (CFM output).
• Possible to use energy recovery.
• It is less noisy during suction and compression time.

Disadvantage:-

• More air hose must be run when distance is an issue, and that means some additional cost.
• It is not portable
• Checking relief valve time to time if it is not be done timely it will be dangerous to use.
• Checking all parts and accessories before starting compressor for safety purpose.

 Applications:-

• It is used in  for spray painting .
• It is used for filling air in tubes Tyre.
• It is used for cleaning purpose.
• It is used as a supercharging process in I.C Engine .
• It is used for fuel injection purpose in air injection diesel engine.
• It is also used in industry to drive air motors like in coal mines.

Types of compressors:-

The air compressor can be classified as many ways .but remaining of them some are the most important and basic types of air compressors that should be know everyone.Here's the schematic diagram of types of compressors.

In the given figure, Compressors are basically classified into two ways:-

1. Positive Displacement Compressor

1. Dynamic or Non- positive Displacement Compressor. 

 Now firstly, I going to explaining about

1. positive Displacement Air Compressors and it's types.

• Reciprocating Air compressors.

• Rotary Air compressors and it's types

2. Dynamic or Non-positive Displacement Compressor.

• Centrifugal Compressor

• Axial compressor
