Definitions

  • the invention involves a "Compressor Performance Ring” for use in flow compressors.
  • the several types of flow compressors include: radial compressors, axial compressors and radial-axial compressors. These compressors are composed of rotors and rotor housings (stators). Rotational speed of the rotor causes the compression and flow of the medium. These compressors are used in such equipment as aircraft turbine engines, gas turbines, power generators, turbochargers used in internal combustion engines, electric compressors, industrial fans and many other applications.
  • the "Compressor Performance Ring” a ring made of lower hardness material with lower strength properties than the rotor, is a solution to reduce the clearance between rotor and housing with the use of simple and reliable technologies with low serial production costs.
  • the "Compressor Performance Ring” may be glued into the rotor housing (stator) or installed in a special groove in the rotor housing.
  • FIG. 1 presents the schematic design of an axial compressor with a "Compressor Performance Ring” installed in the groove.
  • a compressor consists of an axial rotor (1), a static rotor housing (stator) (2) and a “Compressor Performance Ring” (3) installed in the rotor housing (2).
  • the ring (3) is installed in such a way as to reduce the clearance between the ring (3) and the rotor (1) to zero or a near-zero value.
  • FIG. 1 presents the "Compressor Performance Ring” installed in the groove of the axial compressor housing.
  • Figure 2 presents the “Compressor Performance Ring” glued into the axial compressor housing.
  • Figure 3 presents the “Compressor Performance Ring” installed in the groove of the radial compressor housing.
  • Figure 4 presents the "Compressor Performance Ring” glued into the radial compressor housing.
