What kind of compressor does centrifugal compressor belong to?

Centrifugal compressor belongs to speed compressor.

Centrifugal compressor is a kind of mechanical equipment that compresses gas through high-speed rotating impeller. Its working principle is that centrifugal force is generated by the high-speed rotation of the impeller, which accelerates the gas from the center to the edge and compresses the gas to a higher pressure under the action of centrifugal force. The advantages of centrifugal compressor are simple structure, small volume, light weight, high efficiency, high reliability and low noise. Widely used in petrochemical, metallurgical, electric power, aerospace and other fields. Speed compressor refers to the compressor that increases the gas pressure by increasing the gas speed. Its working principle is to accelerate the gas through the high-speed rotation of the impeller and compress the gas to a higher pressure under the action of centrifugal force. Speed compressors include centrifugal compressors and axial compressors.
