Centrifugal air compressor applications range from chemical plants to oil and gas refineries and various on-shore and off-shore gas injection applications.
The application of a centrifugal air compressor leads to a pressure rise by incorporating velocity into a fluid flow. This velocity is then transformed into an increase in static pressure. The device achieves this by interfering with the flow and reducing it down with the help of a diffuser.
The diffuser of the centrifugal air compressor converts the maximum portion of the flowing air velocity into static pressure.
Centrifugal Air Compressor VS Rotary Screw
Before you purchase an air compressor for your needs, make sure you go through enough resources highlighting centrifugal vs screw air compressors, as it will help you have a better idea of how these tools work.
Rotary screw air compressors, as their name suggests, work with rotation. The rotary screw is responsible for air compression. Notably, rotary screw air compressors are less complex than reciprocating compressors. You can get a better idea of this when you compare rotary screw diagrams with centrifugal compressor diagrams.
While centrifugal air compressors work differently than rotary compressors, they more or less offer similar results. What makes centrifugal air compressors a good choice is they are more efficient and it is also easier to customize them.
How do Centrifugal Air Compressors work?
Centrifugal air compressor working revolves around converting the energy utilizing multiple steps of compressing and cooling the air. In a centrifugal air compressor, the pressure developed depends on the continuous conversion of angular momentum.
The application of centrifugal air compressor leads to large volumes of refrigerant and that too on low pressure. In a centrifugal air compressor, the pressure ratio is increased by the tip speed of the blade.
Centrifugal Air Compressor Efficiency
Air compressor efficiency depends on many factors, including the size and type of air compressors. As a general rule, centrifugal air compressor efficiency hovers between 0.70-0.85, while it lies anywhere between 0.65-0.75 for rotary air compressors.
Types of Centrifugal Compressor
Different types of centrifugal compressors are available in the market, including single-stage compressors, multistage centrifugal compressors, small centrifugal air compressors, etc. We’re going to discuss a few of them down below.
Single Stage Centrifugal Compressor
Single-stage compressors are among the most popular centrifugal-type air compressors that come with a single impeller. The purpose of the impeller is to direct the flow of air. This type of centrifugal air compressor also includes a diffuser and guide vanes.
Prominent single-stage centrifugal air compressor examples include over-hung compressors, integrally geared compressors, and more.
Multi-Stage Centrifugal Compressor
Multi-stage centrifugal compressors are designed to pass the air through multiple stages. These compressors are used in a wide range of applications.
Multi-stage centrifugal compressors are ideal for situations when single-stage compressors are not able to fulfill the desired pressure requirements. Examples include split-casing multi-stage centrifugal compressors, bell casing compressors, and pipeline compressors.
Uses of Centrifugal Air Compressors
Centrifugal air compressors can be selected for plant air compression and various other air separation applications. They’re also used for transmission and storage of natural gas as well as different gas injection applications.
Centrifugal Air Compressor Advantages and Disadvantages
In this section, we’re going to highlight centrifugal air compressor advantages and disadvantages.
Pros
Cons
Centrifugal Air Compressors Parts
A basic centrifugal air compressor comes with 4 centrifugal compressor parts – inlet, impeller, diffuser, and collector.
Inlet is a simple pipe that is responsible for controlling the flow of air.
The impeller is the centrifugal compressor component consisting of multiple blades that increases the energy of the gas.
Diffuser converts the kinetic energy of the gas into pressure by lowering the gas velocity.
As its name suggests, the collector collects the flow and transmits it to a downstream pipe.
Centrifugal Air Compressor Manufacturers
There are many centrifugal air compressor manufacturers in the market that are known for high-accuracy products. We’re going to highlight a few of them in the following section.
