Working Principle of Centrifugal Compressor

Centrifugal compressors operate based on centrifugal force. Gas enters the compressor inlet and is accelerated by a high-speed rotating impeller, generating significant centrifugal force. This force pushes the gas outward, where its kinetic energy is transformed into pressure energy within the compression chamber, completing the compression process.

1. Gas inlet stage: Low-pressure gas enters via the air inlet and flows into the rotating impeller.
2. Centrifugal acceleration stage: The impeller spins rapidly, increasing gas velocity and kinetic energy, pushing the gas to the compressor shell.
3. Compression stage: Gas flows along the compressor wall, velocity is converted into pressure, forming high-pressure gas.
4. Exhaust stage: Compressed gas is discharged through the exhaust port, completing the process.
