Definitions

  • the invention relates to the field of centrifugal compressors of exhaust gas turbochargers. It relates to a device for blowing air into the flow channel of a centrifugal compressor according to the preamble of patent claim 1.
  • stabilizers are used in the intake of the compressor wheel in a variety of radial compressor stages of the latest generations.
  • the demand from the market for steadily higher pressure ratios in compressors of exhaust gas turbochargers is unbroken.
  • the increase in the pressure ratio via an increase in the speed are limits set by the Verêtrradmaterials because the usable map limiting pumping and swallowing limit converge with increasing speed.
  • the usable characteristic map width thus decreases continuously in the direction of higher pressure conditions.
  • a diffuser with a smaller flow cross section can be used with a constant compressor wheel size.
  • the pumping limit shifts to smaller volume flows, resulting in a larger usable characteristic map width while maintaining the wheel slip limit.
  • a disadvantage is that the efficiency is reduced, especially at partial load. This disadvantage can be avoided by appropriate measures to increase the stability of the given compressor stages at maximum load. This can be done by injecting air from the housing into the flow channel in the unopened space between the blades of the compressor wheel and the vanes of the diffuser.
  • the dynamic stability in the range of high pressure conditions can be increased by the injection of air.
  • the object of the invention is to provide a simplified, inexpensive device for blowing air into the flow channel of a centrifugal compressor, which can be mounted in particular with little effort and has a high reliability in operation.
  • This object is achieved by a device for blowing air into the flow channel of a centrifugal compressor with the features of patent claim 1.
  • the nozzles are shaped as injection openings in the housing wall delimiting the flow channel. The injection openings are fed directly by means of air taken from the flow channel downstream of the diffuser. This air has compared to the flow in the flow channel in front of the diffuser on an increased pressure. This results in a passive, dynamic stabilization system of a compressor stage in the range of high pressure conditions, which manages without additional control or actuators.
  • An advantageous embodiment of the inventive device for blowing air into the flow channel can be easily realized by the cast compressor housing parts are provided directly with the corresponding openings. There are no additional nozzle elements or compressed air connections necessary. The distribution of compressed air on at most several injection openings via an at least partially annular formed, integrated as a cavity in the compressor housing air duct.
  • Fig. 1 shows a section through a centrifugal compressor with a mounted on a rotatably mounted shaft compressor wheel.
  • the compressor wheel has a central hub 10 and thereon arranged rotor blades 11.
  • the compressor wheel is arranged in the compressor housing.
  • the compressor housing comprises a plurality of the flow channel for the medium to be compressed limiting parts.
  • an inner compressor housing wall In the area of the rotor blades of the compressor wheel, an inner compressor housing wall, the so-called insert wall 31, limits the flow channel 41 radially outwards. Radially inside the flow channel is limited in this area by the hub of the compressor wheel.
  • the flow channel 42 on the side opposite the insert wall 33 is bounded by a diffuser wall 20.
  • the diffuser comprises diffuser 21 in the flow channel are arranged. Further downstream of the Diffusorleitschaufeln the flow channel 42 opens into the collecting cavity 43 of the spiral-shaped screw housing 32, from where a line, not shown, leads to the combustion chambers of the internal combustion engine connected to the exhaust gas turbocharger.
  • the air flow is indicated in the figures in each case with the thick, white arrows.
  • the inventive device for blowing air into the flow channel comprises a return air duct 44, which leads from the collection cavity 43 downstream of the diffuser vanes 21 into the flow channel 42 between the rotor blades 11 of the compressor wheel and the vanes 21 of the diffuser. As shown in Fig.
  • the air duct 44 may be formed as a cavity, which is bounded by insert wall 31, screw housing 32 and a partition wall 33 of the compressor housing.
  • the air duct 44 leads from an inlet opening 52 in the compressor housing wall in the region of the collecting cavity 43 to an injection opening 51 in the compressor housing wall in the region between the rotor blades 11 of the compressor wheel and the guide vanes 21 of the diffuser.
  • the injection opening 51 which opens into the flow channel 42 in the region between the rotor blades 11 of the compressor wheel and the guide vanes 21 of the diffuser, is not cylindrical, but has an inner Coanda surface structure. This means, as shown enlarged in FIG. 3, that the compressor housing wall has a rounding projecting into the injection opening, along which the air can flow according to the Coanda effect.
  • the flow in the flow channel has a strong tangential component on exit from the area of the rotor blades of the compressor wheel.
  • the Coanda effect ensures that when the air is blown into the flow channel no strong turbulences and cross flows occur. Instead, the air, which is likewise injected into the flow channel in the tangential direction, remains attached to the rounding of the injection opening 51 and is introduced into the flow in the edge region of the flow channel, as indicated by the thin arrows in FIG. 2 and FIG.
  • the injection into the flow channel is passive, that is without control or actuators. Due to the higher pressure in the collecting cavity 43 relative to the flow channel 42 in the region between the blades 11 of the compressor wheel and the guide vanes 21 of the diffuser results in a compensating flow.
  • a plurality of injection ports 51 may be provided. These can all be connected to a single, annular or at least partially annular air duct 44. Likewise, a plurality of inlet openings 52 can be arranged in the circumferential direction along the collecting cavity 43. Instead of an annular air duct 44, a plurality of divided air ducts divided by radially extending partition walls may be present, which supply one or more injection openings 51 with air for blowing in each case. The openings of the device according to the invention can already be embedded in these during the production of the compressor housing parts.
  • prefabricated nozzle elements 62 poured into the housing wall and materially connected to the housing wall, or by the special contour of the injection openings is already integrated in the mold.
  • a material is used, which connects to the casting wall with the steel of the housing wall without melting itself.
  • the inlet and the injection openings can also be introduced into the compressor housing walls at a later time.
  • nozzle members 61 which are positively or non-positively connected to the compressor housing wall 31. This allows, for example, the retrofitting of existing turbocharger with the inventive device for blowing air into the flow channel.
