Definitions

  • the energy conversion process in a centrifugal compressor takes place by means of a rotating blading of a compressor impeller, which impels a spin to the pumped medium or fluid to be compressed, such as, for example, atmospheric fresh air.
  • the power of the swirling flowing fluid behaves on the one hand proportional to the peripheral speed of rotating as a solid blading and on the other hand proportional to the concentric rotating component of its speed, which in turn has proportional to the rotational speed of the solid and thus to the speed of the compressor impeller.
  • the throughput promoted with the centrifugal compressor also behaves proportionally to the rotational speed of the rotating blading for flow velocities that can be considered low compared to the speed of sound of the fluid.
  • a compressor impeller for a radial compressor comprises a plurality of impeller passages for passing a fluid to be compressed, the impeller passages each having a fluid inlet end and a fluid outlet end and wherein the respective impeller passages at the fluid inlet end have a first cross sectional area and at the fluid exit end a second cross sectional area to have.
  • the compressor impeller according to the invention is characterized in that a size ratio of the second cross-sectional area to the first cross-sectional area is smaller than 0.7.
  • such a partition has the advantages that on the one hand it does not reduce the cross-sectional area of the respective impeller passage at the fluid inlet end and on the other hand causes a better transfer of the mechanical work or kinetic energy performed by the compressor impeller to the fluid to be compressed.
  • the two partial passages of each impeller passage at the fluid outlet end each have an outlet cross-sectional area, wherein a sum of a respective Size of the respective outlet cross-sectional areas of the two partial passages is equal to a size of the second cross-sectional area.
  • the feedback passage can be designed such that a secondary portion or secondary flow of the conveying medium or fluid to be compressed downstream of the first cross-sectional area relevant for the throughput, in particular at high compressor speeds in the flow direction of the main flow via the feedback passage, reunites with the main flow of the fluid.
  • a vehicle equipped with such an exhaust gas turbocharger internal combustion engine (internal combustion engine) of a vehicle has in particular a higher power output and lower fuel consumption.
  • the impeller passages 23 are each of the outer circumference 21 a of the impeller hub 21, opposite blade surfaces 22 a, 22 b of the respective adjacent impeller sch on a 22, 22 and the outer periphery of
  • each impeller passage 23 each have an outlet cross-sectional area AAi or AA 2 at the fluid outlet end 23b of the respective impeller passage 23.
  • the radial compressor 1 according to the invention has an apparent in the map wider stable working area, resulting in interaction with
  • the design of the vanes 17 and the dimensioning / arrangement of the feedback passage 12 make it possible for the feedback passage 12 to be arranged so as to be particularly at high
