How does the impeller of an air compressor work? Please explain, experts
May I ask if theoretical knowledge of the system is required, or calculation formulas? That would make things complicated. Is this considered an open impeller? There is also a diffuser involved, which uses the rotation of the impeller to convert kinetic energy into pressure energy (potential energy)
The diffuser chamber, curve, and recirculation chamber: after being ejected by the impeller, the flow first enters the diffuser chamber, where it expands, slows down, and its pressure increases (dynamic pressure is converted into static pressure). It then enters the curve, where its originally radial outward velocity is changed to a radial inward velocity. Finally, it enters the recirculation chamber, where this radial inward velocity is transformed into an axial velocity directed toward the inlet of the next stage of impellers
