Axial flow compressor

Thread Content

Axial flow compressors are a type of large-scale air compressor; their maximum power can reach 150,000 KW, with an exhaust volume of 20,000 m³ per minute. Their compression efficiency can be around 90%, which makes them more energy-efficient than centrifugal compressors. The static vane adjustment mechanism of the axial flow compressor, along with the intermediate cylinder that drives this mechanism, are part of standardized housings of the same model but with different stages; the inlet and exhaust cylinders are identical. The difference in length between stages is achieved through the use of modular molds. When a certain stage is not in use, all structural elements remain the same, aside from the difference in axial length. The main shafts are made of nickel-chromium alloy steel, while the blade material is chromium stainless steel. The structural dimensions of the stationary blade casing, shaft seals, seals, coupling systems, as well as other auxiliary devices of axial flow compressors, the lubrication system, control system, and protection system are all highly sophisticated. The reaction for the first 6 levels is 70%, while the reaction for the subsequent levels is 100%.
