　　What is the difference between centrifugal air compressors and screw air compressors?There are many types of air compressors, including centrifugal air compressors, screw air compressors, reciprocating air compressors, etc.Essentially, there is no distinction between good and bad air compressors, but rather what kind of air compressor we need,The Turbo-Tech editor pointed out that one can choose a suitable air compressor based on the usage environment, exhaust volume, power requirements, etc.

　　What is the difference between centrifugal air compressors and screw air compressors?

　　1. Introduction to centrifugal air compressors

　　A centrifugal air compressor uses a high-speed rotating impeller to generate pressure on the air under the action of centrifugal force, while obtaining speed. After leaving the impeller, the air gradually converts kinetic energy into pressure energy through expansion channels such as diffusers, thereby increasing pressure. After the first stage of compression is completed, it enters the next stage of compression and is discharged after reaching the rated pressure.

　　Centrifugal air compressors are generally composed of multiple stages, and the higher the exhaust pressure, the more stages are required. They are divided into multiple stages, with intermediate gas coolers between each stage.

　　Main characteristics of centrifugal air compressors

　　+High speed, compact structure, large single machine exhaust volume, and high efficiency;

　　+Operating under pure oil-free conditions, compressed air is not contaminated by lubricating oil and of high quality;

　　+Durable, with a very low failure rate during long-term continuous operation, and a long service life;

　　+Less vulnerable parts, convenient and affordable maintenance.

　　2. Introduction to screw air compressors

　　The screw air compressor is compact, non pulsating, with fewer vulnerable parts, high single-stage pressure ratio, and a wide range of operating conditions;

　　Disadvantages:

　　+ The processing flow rate of screw air compressor is lower than that of centrifugal compressor;

　　Summary: The above content is an introduction to "What is the difference between centrifugal air compressors and screw air compressors?" I believe you have a general understanding.Centrifugal air compressors are suitable for working conditions with stable gas consumption and high flow rate, and the gas is completely oil-free.The screw air compressor has a small displacement per unit and can be freely combined, suitable for working conditions with large fluctuations and low requirements for air oil content;If you would like to learn more, please feel free to consult Turbo-Tech Sales 400-8861856.
