Aerodynamic Performance of Centrifugal Compressors LESSON (ONE)

Basics
The centrifugal compressors are machines of dynamic flow, through which the gas flows mainly in radial form. The energy necessary to increase the pressure of the gas is transmitted for the blades or trowels of the impellers during its rotation. The physical principle at issue is based on the conversion of the kinetic energy given by the impelling equipment in movement in static energy of the gas, that is to say, from speed to pressure.
The basic components of a compressor are: Casing, The Stator, The Rotor, The Bearings, The Seals Interstage, and The Seal System to isolate the product in compression of the environment surrounds that it and The Lubrication System.

Centrifugal Compressors Types
Axial Centrifugal Compressors are those through which gas flows mainly in radial form, that is to say, in parallel line of the rotor shaft a typical example is the compressor of the Gas Producer of a Gas Turbine, these are characterized by handles great gas volumes but to low pressures. In radial compressors, gas in compression it flows mainly in perpendicular direction of the rotor shaft, are characterized to handle great gas pressures. A variant exists that is the mixture of both types in a same axis (to see drawings).

The options but known to exert movement on a centrifugal compressor are:
.Gas Turbine
.Turbine a vapor
.Electric Motor
.EolicTurbine
.Reciprocante Motor
