Definitions

  • the invention relates to a device for adjusting the ring-shaped pivotable diffuser guide vanes of a radial turbo compressor, the guide vanes each having a crown pin parallel to the crown axis and are rotatably mounted about this pin in the housing and handlebar levers are arranged on the blade pin and are pivotally connected to an adjusting ring rotatably mounted on the housing are.
  • the operating range for turbocompressors is defined by two limits with regard to the volume to be pumped. As the volume flow increases, the so-called swallowing limit is reached at some point, and when the volume flow drops, the turbo compressor reaches the so-called instability limit, at which the compressor begins to pump and controlled operation is no longer possible. This is made even more difficult when it comes to turbo-compressors that require a high pressure ratio. In an effort to expand the operating range of the individual compressors as much as possible, a wide variety of solutions have been developed to shift the instability limit.
  • the invention has for its object to find a control in a radial pressure compressor having a high pressure ratio, which allows the passage of a large range of different volume flows at constant pressure and constant efficiency.
  • This adjustable multiple guide device allows the optimum adjustment of the operating range of the radial turbo compressor to the required values in a simple manner, namely through the free adjustability of the individual guide devices with respect to one another, the different aerodynamic adjustment laws of the individual guide devices being taken into account by different articulation radii. It is not necessary to dismantle the machine. Furthermore, the individual radial compressor stages can thus be precisely adapted to one another. Surprisingly, practical tests with the control device according to the invention showed an approximately 40% increase in the stable working range at the instability limit. A corresponding radial turbo compressor with an adjustable inlet guide served as a basis for comparison.
  • an embodiment of the invention provides that the individual actuating rings of two steps standing back to back are adjustable with respect to one another and connected to one another in a rotationally fixed manner. An individually adjustable and reliably functioning control device has thus become possible.
  • the invention is illustrated using an exemplary embodiment and is described in more detail below.
  • the two radial impellers 2, 3 with the impeller rear sides are arranged on a common shaft 1.
  • the impellers 2, 3 are followed by diffuser vanes 4, 5, with a blade journal 6, 7 being attached in each of their first flowed thirds, around which the diffuser vanes can be pivoted and with which they are mounted in the housing 8.
  • adjustable control levers 9 are attached, which are movably connected to adjusting rings 10, 11 which are rotatably attached to the housing 8.
  • the adjusting ring 10 is firmly connected to an actuating ring 12 which ensures the synchronous adjustment, while the adjusting ring 11 is adjustably connected to the actuating ring 12.
  • the radial turbo compressor can be set precisely for the respective operating conditions.
  • a central servo drive 13 enables a synchronous adjustment in a simple manner with simultaneous individual adjustability of all control devices. It is no problem to take into account the different adjustment laws of the individual guide devices by appropriately dimensioning the handlebar levers or the adjusting rings.
