Centrifugal Compressor Working Principle

Centrifugal compressors achieve gas compression using centrifugal force through the following process:

1. Gas intake: Low-pressure gas enters the compressor through the inlet.
2. Centrifugal acceleration: The gas is accelerated by a high-speed rotating impeller, gaining speed and kinetic energy as centrifugal force pushes it outward.
3. Energy conversion: As the gas moves into the compression chamber, the impeller’s kinetic energy is converted into pressure energy, efficiently increasing pressure via optimized channel and chamber design.
4. Exhaust output: Compressed gas is discharged through the exhaust port at the required high pressure.

This highly efficient and continuous process makes centrifugal compressors ideal for industrial applications requiring long-term, high-flow, and high-pressure gas supply.
