Definitions

  • the invention relates to a single-stage vane compressor according to the preamble of the main claim.
  • Single-stage water-cooled vane compressors are known in principle and are used for various applications, for example for suction vehicles and stationary systems (see brochure from Mannesmann Demag, "Demag-Wittig compressor vacuum pumps for suction vehicles and stationary systems", October 1986, p. 10 - 14).
  • These water-cooled vane compressors have a housing with feet and a cooling water jacket.
  • a rotor is arranged eccentrically to the housing bore, which is provided with radially movable slides and whose shaft journals are supported in bearings by covers attached to the end faces of the housing.
  • Flanges for sucking in or pushing out the medium are arranged on the housing jacket offset over the circumference.
  • DE-OS 1403608 discloses a generic, water-cooled, single-stage vane compressor, in which the cooled housing jacket is divided into channels by essentially longitudinal walls distributed over the circumference.
  • one of the longitudinal walls has no passage, the inlet for the cooling water being arranged on one side and the outlet on the other side of the partition. This forces the cooling water to zigzag through the casing.
  • the jacket space is divided into two flow systems by a transverse wall perpendicular to the axis of rotation.
  • a disadvantage of this construction is that the increased temperature level prevailing in the pressure range is only insignificantly influenced by the proposed arrangement of the cooling channels.
  • DE-OS 36 03 809 shows a two-stage vane compressor, in which the rotor axis is arranged symmetrically to the outer contour of the housing.
  • the cover and the casing are liquid-cooled, the cooling liquid space is not divided.
  • the temperature distribution is therefore very different over the circumference and because of the distortion of the housing, larger sealing gaps must be provided.
  • the object of the invention is to provide a generic vane compressor that can be operated with narrower sealing gaps and thus has a better efficiency.
  • the vane compressor according to the invention does not have a continuous cooling water jacket, but rather cooling channels drawn over the cover, so that forced circulation is achieved.
  • the cooling water jacket is axially divided with respect to the suction and pressure side and the connection between the cooling water jacket on the suction and pressure side is made via the housing cover.
  • the entry of the cooling water has been placed in the area of bottom dead center, namely offset over the longitudinal extent of the housing.
  • the cooling chambers in the bottom dead center area are larger than in the top dead center area.
  • Tighter sealing gaps mean compared to the the known compressors better efficiency.
  • the uniformity of the temperature distribution also minimizes the different linear expansions of the suction and pressure side. This means that narrower gaps in the front area can also be moved, which in turn improves the efficiency of the machine.
  • the arrangement of larger cooling chambers in the bottom dead center area is achieved in that the rotor axis coincides with the center axis of the housing and the housing bore is arranged eccentrically to it.
  • the feet and the flanges are arranged symmetrically to the rotor axis, so that universal installation in the vehicle is possible. Regardless of which longitudinal side of the compressor is used as a stop surface, the center of the rotor shaft is maintained and thus the agreement with the axis of the drive machine.
  • FIGS. 1 to 3 show a water-cooled vane cell compressor 1 according to the invention in two cross sections and in a longitudinal section.
  • This consists of a one-piece housing 2, which in has upper and lower cooling channels.
  • Flanges 3, 4 for the suction and pressure side are also integrated in the housing 2.
  • 1 and 2 show the central arrangement of the rotor 5 according to the invention with respect to the center axis 6 of the housing 2.
  • the distances from the central axis 7 in the X direction to the end faces of the flanges 3, 4 or to the axes of the feet 9 and the distances from the central axis 8 in the Y direction to the end faces the feet 9 have been provided with an equal sign.
  • the housing bore 10 is arranged according to the invention eccentrically to the rotor axis 6.
  • the displacement 11 is shown in the Y direction.
  • the offset arrangement of the housing bore 10 has the advantage that in the area of the bottom dead center 12 and the pressure flange 4 larger cooling chambers 13, 14 can be arranged compared to those 15, 16 in the area of the top dead center 17 and the suction flange 3. Since the greatest amount of heat is generated in the pressure flange area as a result of the adiabatic compression of the medium and the friction of the slides 18, particularly intensive cooling is desired here in order to make the temperature distribution in the circumferential direction as uniform as possible.
  • the cooling jacket is axially separated 19, 20.
  • the water flow is indicated by arrows.
  • the cooling water inlet 21 takes place in the area of the bottom dead center 12 at the outermost edge of the longitudinal extent of the housing 2. (In this exemplary embodiment on the right side).
  • the cooling water inlet 21 was placed in the sectional plane in FIG. Behind the inlet opening 22, the cooling water flows on the one hand in the longitudinal direction of the housing (from right to left in this exemplary embodiment) and at the same time from bottom to top. So that the jacket region opposite the inlet opening 22 is also adequately cooled is, the cooling water flows simultaneously through the recesses provided in the cover 23 to the other side and from there in the longitudinal direction of the housing 2.
