There are many compressor types in the market. This aspect makes it difficult to choose what is best for your project. However, you can also look into your applications and compressed air needs to determine what will work for you. One of the most popular compressor types is a centrifugal air compressor.
In this complete buying guide, you will learn everything about centrifugal air compressors. Here is a sneak peek into what to expect.
A centrifugal air compressor, often known as a turbo compressor, is a radial-design dynamic compressor. Dynamic compressors operate at constant pressure and are affected by external factors such as variations in inlet temperatures.
Here is the centrifugal air compressor working mechanism:
Air is sucked into the center of a revolving impeller with radial blades, and centrifugal force pushes it into the center. The pressure rises due to the radial movement of air, and kinetic energy is generated in the impeller of centrifugal air compressors. The kinetic energy of the air is transformed to pressure before it enters the impeller’s core by going via a diffuser and volute.
Each stage contributes to the compressor unit’s overall pressure rise. To achieve a higher pressure, a series of stages can be arranged in a sequence. This aspect depends on the pressure required for the application. Oil and gas frequently use this form of multi-stage application. Low-pressure, single-stage applications are also employed in wastewater treatment plants to attain the necessary pressure ratio.
Ultra-high-speed electric motors drive the impellers. As a result, a compact compressor without a gearbox and the related oil-lubrication system is produced, making it oil-free and suitable for applications requiring 100% oil-free air.
Three parts make up the centrifugal compressor’s core;
The air passes through the impeller, where the whirling blades boost the air’s kinetic energy.
The diffuser changes the airflow by progressively slowing it down and converting the kinetic energy into pressure.
The diffuser discharges into the collector, also known as the volute, formed like a snail shell. The airflow from the diffuser is gathered in the volute and distributed to an outlet pipe.
There are different centrifugal air compressor types. In most cases, centrifugal air compressor manufacturers offer standardized or custom-engineered centrifugal compressor solutions.
There are three major configurations possible for centrifugal compressors:
An axial multi-stage operates at a low speed and is primarily driven by an induction motor. To progressively build up the pressure, many impellers are lined up axially after each other. Integrally geared centrifugal air compressors are usually more efficient.
An induction motor rotates at a low speed, which drives geared turbos. Due to gearbox transmission, the radial impellers are spinning at a high speed. For these high speeds, special bearings are necessary, most often hydrodynamic bearings.
Depending on the needed pressure and flow, single or multiple impellers can be mounted.
High-speed turbos are radial turbochargers that do not have any gears. The impeller is driven directly by the motor. This necessitates the use of Permanent Magnet motor technology since the motor must run at high speeds. Magnetic bearings are employed to avoid any touch or wear at these high speeds, making them more reliable.
Centrifugal air compressor impellers can be shrouded or unshrouded. Additionally, the blades can be two-dimensional or three-dimensional.
Centrifugal air compressors can be enhanced in many ways. Here are some of the ways to increase the efficiency of a centrifugal air compressor:
Centrifugal air compressors are ideally suited to applications that require consistent airflow. Additionally, they are suitable for plants where they can be used for baseload operations. This allows other types of compressors to be employed as trim machines to meet peak demands.
A centrifugal air compressor uses a spinning element to enhance the velocity of the air, which is subsequently converted into potential energy in the form of pressure.
Centrifugal technology is used by companies that require a massive supply of compressed air. Each machine is tuned to its specific power range. Each pressure variety has its own impeller that has been optimized. The centrifugal compressor’s impellers are built to last, making it a particularly dependable machine.
Industrial centrifugal air compressors are used in a wide range of industries, including automotive, food, pharmaceuticals, textiles, power, renewable energy, wastewater treatment, chemical manufacturing, and oil and gas. Small centrifugal air compressors are used for domestic applications.
There are many compressor brands. Here are some examples
Centrifugal air compressors are currently the most efficient compressors in the market. This is owed to their ability to meet constant airflow demands in industrial applications. Are you looking for centrifugal air compressors for your projects? Check various China air compressors for all your centrifugal air compressor needs. This article should guide you into making the right choice.
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 Compressor 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.
