Centrifugal Compressors:
The machine in which velocity and pressure are imparted to the air or gas in a radial direction by one or more impeller – diffuser combination.
mining, transportation and storage of gas, on-shore and off-shore installations. The range of application can be expanded still further by combining these centrifugal compressors with other compressor type such as axial flow or reciprocating compressors.
The wide range of processes in which centrifugal compressors are employed makes varying demands on these machines. Compressor demand is dependent on such factors as fluid handled, pressure ratio, the volume flow, the number of inter stage coolers, injection and extraction of the medium, and the type of shaft sealing.
Taking all this factors into consideration, the major compressor manufacturers have developed series of centrifugal compressors offering optimum engineering solution implemented by the use of standard components. These series include the two basic types, distinguished by horizontally or vertically split casing, compressors with two or three pairs of main nozzles, and compressors with additional side stream nozzles.
Horizontally split casing permits simple removal of rotor and facilitates the checking of labyrinth clearances and o-rings. As pressure level rise and gas molecular becomes smaller, vertical split casings are employed.
