Introduction of compressor

Basically, compressor is mechanical device that increase the pressure of a gas by reducing its volume. An air compressor is a type of gas compressor. 

An air compressor increases the air or gas pressure at least 3 time higher than that of atmospheric pressure so the compression ratio for compressor is more than 3.

The tern compression is use for measure parameter define by   total outlet pressure divided by total inlet pressure of the system. This tern is used for comparing the pumping and pressurization for compressor.

Compressors is also used for transfer gas or air from one place to another place with increase pressure, reduce volume.

Compressor are used for many purposes like home applications like fridges, Air condition, automobiles shop, industrial application and other.

Working principle of compressor is same as pump but pump is use for transfer liquid with increase pressure. Now day it is use for utility purposes for industries.

Types of compressor

Mainly compressor is classification on the basis working principle, these are mentioned below.

Classification on the basis working principle

1. Dynamic compressors 
2. Positive displacement compressor

A positive displacement compressor reduces the volume of a fluid mechanically to increase the pressure.

Further both types of compressor are divided in many types these are following,

Positive displacement compressor

1. Rotary Screw Compressor
2. Screw compressor
3. Lobe type compressor
4. Liquide ring compressor
5. Vane type compressor 

Reciprocating Compressors

1. Diaphragm compressor 
2. Piston and plunger compressor

Dynamic compressors

Dynamics compressors change the velocity of fluid which result in the increase in pressure. In this compressor kinetic energy convert to pressure energy by reducing the volume of the fluid.

There are two types of Dynamic compressors, these are following

1. Axial Compressor.
2. Centrifugal Compressor

Different between Dynamic compressors and positive displacement compressor

Positive displacement compressor

1. It can compress the fluid in fix amount
2. Velocity of fluid need not to be increase
3. Discharge fix amount of flow with varies in output pressure.

Dynamics compressor

1. Compress the fluid in continuous operation
2. Velocity of fluid need more than positive displacement type
3. Output flow rate is in variable form with pressure as well
