In this article, we will introduce several types of compressors and explain the differences between them. Stay with us.

First we introduce the Centrifugal Compressor and then we review the Centrifugal Compressor Work. We will also introduce the types of Centrifugal Compressor.

A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor.

Compressors are similar to pumps: both increase the pressure on a fluid and both can transport the fluid through a pipe. 

Centrifugal compressors, sometimes called radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.

Centrifugal compressors are considered as a dynamic compressor type that has a radial design.  These compressors work with a constant pressure unlike the ones working at a constant flow. Plus, any changes in the external conditions affect the performance.

Types of Centrifugal Compressor

Centrifugal Compressor generally consists of 2 categories:

• Single Stage Compressor
• Multi-Stage Compressor

Single-stage compressors are among the popular types of centrifugal compressors available on the market. This type has a single impeller for directing the air or other gases for its specific purpose. The single-stage compressor also contains a diffuser and connected guide vanes.

But what is axial compressor vs centrifugal compressor?

An axial compressor is a gas compressor that can continuously pressurize gases. It is a rotating, airfoil-based compressor in which the gas or working fluid principally flows parallel to the axis of rotation, or axially. 

Some of the differences between them are:

 

• Centrifugal compressors are easier to design and manufacture compared to axial compressors.
• Contrary to centrifugal compressors, axial flow compressors do not change the direction of the gas.

radial compressor

radial compressors is actually another name for Centrifugal compressors. A radial compressor contains radial blades on its rotating impeller and the air is drawn into the center of this unit. The centrifugal force pushed the air into the center. The air’s radial movement inside these compressors will raise the pressure, resulting in the generation of kinetic energy.

 

 

 

 

 

rotary compressor vs reciprocating compressor

A reciprocating compressor or piston compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.

• Size

1. The size of the rotary compressors is smaller than the reciprocating compressor for the same discharge.
2. The size of the reciprocating compressor is bulky and larger than the rotary compressor for the same discharge.
