Air Compressors

With the advancement of science and technology, compressors and its types have played myriad roles inthe construction of refrigerators, pumping machines and in many other construction projects too. But, what is actually a compressor and how does it work, is still a questions in the minds of thousand illiterates as well as few literates. A compressor is basically a device which increases the pressure of a gas (generally air) by reducing the volume of the respective gas or fluid inside it. Among the different types of compressors we see commonly, the air compressor is of prime importance. An air compressor is a mechanical tool that sucks in air at atmospheric pressure level and supplies it at a higher pressure level by internally compressing the air. This machine aims to convert power that is usually drawn from an electric motor or a gasoline engine to kinetic energy.

Methods of air compression

There are several methods to compress the air. Two basic categories of air compressors are involved for the purpose of the same. These are the:

Types of air compressors

The variety of air compressorscan be classified under the following broad heads:

The positive displacement compressors can be further subdivided into rotary compressors and reciprocating compressors.

The reciprocating compressors again can be divided into:

  1. In-line reciprocating compressors
  2. V-shaped compressors
  3. Tandem piston compressors
  4. Single acting compressors
  5. Double acting Compressors
  6. Diaphragm compressors

The rotary screw air compressors can be classified into:

The roto-dynamic compressors have:

  1. Centrifugal compressors
  2. Axial flow compressors

The various air compressor manufacturing companies not only have served mankind from the very time these were invented, but have also employed millions of young unemployed men to help them secure their future.
