PRINCIPLE OF CENTRIFUGAL COMPRESSOR

When the gas enters theCompressor - severalForces acting on the movinggas

One of the forces is the Aerodynamic force.same force causes the airplane to lift of The air wing.

This force moves the gas from low pressure eye

To high pressure of the edge

Gas enters the compressorTo the suction part and is directedTo the centre of the impellerAs the impeller rotates the gas rotates with him

The circular motion generates the centrifugal forces that lift the gas moves away from the centre to the edge of the impeller

The circular motion generates the centrifugal forces that lift the gas moves away from the centre to the edge of the impellerGenerates Suction in the centre of the impeller

Generates Suction in the centre of the impellerThe speed Of the gas of the outside of the impeller Is faster than the inside of the impeller.As a result the gas is forced to increase the speed as it is moved outward.The moving force + centrifugal force increase the motion results the increaseof the kinetic energy of the gas

As the gas moves outside edge of the Impeller it enters the larger area of The Casing called Diffuser or Volute Volute The diffuser is designed So that the flow area Increases as the gas Leaves the impeller

This increased area causes the gas slowdown and motion energyIs converted to pressure

Finally when the gas leaves theCompressor :The centrifugal force .

Finally when the gas leaves the compressorDynamic Force Centrifugal Force Change in velocity Will have to Produce The discharge Pressure Several times Higher than the inlet pressure

We can boost the gas pressureEven higher By using multi staging Of Centrifugal Compressor
