My understanding is that the airflow increases in velocity as it passes through an impeller; then, as it moves through the volute, its kinetic energy decreases while its potential energy increases (resulting in pressure). This entire process constitutes one stage
The number of times the gas is compressed in the compressor.
A compressor generally consists of several “stages,” where a stage is a basic working unit made up of an impeller and the fixed components that work in conjunction with it.
Stage refers to the impeller; the number of stages indicates how many impellers there are
The stage of a compressor refers to the number of times the gas is compressed, or the number of impellers/pistons in the compressor’s head; each impeller/piston performs one compression of the gas, which constitutes one stage
Due to the high pressure requirements of the process, when a single compression is not sufficient, the compressed medium is compressed again; this is known as secondary compression. If the pressure still does not meet the requirements, tertiary or quaternary compression can be carried out. This is multi-stage compression.
The number of stages indicates the number of functions: stage 1 means single-acting, while stage 2 means double-acting. Multiple stages are used to increase the pressure at the compressor outlet.
