The centrifugal air compressor is a dynamic compressor which depends on the transfer to energy from a rotating impeller to the air.

Centrifugal compressors produce high-pressure converting angular momentum imparted by the rotating impeller. The centrifugal compressors rotating at higher speeds than the other types of compressors. These types of compressors are also designed for higher capacity to work because flow through the Air compressor is continuous.

The inlet guide vanes are the most common method to control the capacity of a centrifugal compressor by closing the guide vanes, volumetric flows and capacity are reduced.

The centrifugal air compressor is an oil-free compressor. The oil lubricated running gear is separated to the air by shaft seals and atmospheric vents.

In this article, we will cover each and every point related to the centrifugal compressor or sometimes called a radial compressor.

The centrifugal compressor is quite different from that of a reciprocating or rotary type compressor. The air passes through the rotating impeller it experiences force or work which is called by centrifugal forces. The increase in pressure and velocity or speed of the air flow through the impeller. The air flow loses its velocity after entering in the different section. The actually a fixed or static component that escorts the air flow when it leaves the impeller. This loss in velocity results in an additional increase of pressure. The impeller and the diffuser contribute about 65% and 35% of the total pressure developed in the centrifugal compressor.

1. Casing and inlet: The mentioned components are usually protected or guarded by a casing or housing. A case house consists of the number of bearings in order to provide radial and axial support of the rotor. The cases also contain nozzles along with inlets and discharge flow connections in order to introduce and extract flow from the compressor.

Casings are of two types:-

 a.) Horizontally split

b.) Vertically split

The impellers are used to assemble on a steel shaft and this assembly is known as compressor rotor. The rotor provides high velocity to the gas with the blades that are attached to a rotating disc. These blades can be used to forward-leaning, radial or backward-leaning depending to upon the desired output. Mostly the multistage compressors use backward-leaning blades as they provide the widest range of efficiency.

The impeller has extracted the gas with high velocity into a diffuser passage. The diffuser usually compromises two walls which form a radial channel. Because of these arrangements, this velocity of the gas decreases and dynamic pressure is converted into static pressure. The diffuser passages are small space between adjacent diaphragms which generally turns to the gas flow 180degree in order to direct it used for towards the next impeller.

The last stage impeller the gas must be collected and transfer to the discharge flange. The component used to the collect gas discharged through the diffuser is called as the collector, Maybe termed as volute or scroll. The collector may also contain valves and other used instrumentation in order to control the compressor.

Types:

There are two types of it:

1. Single stage centrifugal compressor

2. Multi-stage centrifugal compressor
