Definitions

  • the invention relates to a device for conveying a gaseous medium in a device with high flow resistance.
  • the device with high flow resistance can be, for example, a ceramic surface burner, which has recently been used in gas boilers.
  • gas boilers with ceramic surface burners are known (magazine: HLH, heating, ventilation / air conditioning, house technology; magazine of the Association of German Engineers for Technical Building Equipment; June 1989, page 308). They have a relatively high flow resistance, which is on the order of 200 Pascal and more.
  • the medium to be pumped can either be air or a combustible gas mixture.
  • the invention is therefore based on the technical problem of creating a device for conveying a gaseous medium in a device with a high flow resistance, in which on the one hand the conveyed medium has a relatively high back pressure and on the other hand has a steep pressure-volume flow characteristic, i.e. in the device, major changes in the pressure generated should only be accompanied by minor changes in the volume flow.
  • the inherent noise of the device must not exceed the inherent noise of known devices for conveying a gaseous medium.
  • a radial fan the housing of which has a spiral inner contour and which has a closed fan wheel with backward-curved blades, the diameter of which is very much larger than its flow outlet width.
  • the pumped gaseous medium has a pressure of 415 Pascals and a volume flow of 6.9 l / s at the intended operating point.
  • the speed of the fan wheel was about 3800 revolutions per minute.
  • the housing 1 of the radial fan is closed with the cover 2.
  • the housing 1 and cover are made of aluminum injection molding.
  • the cover 2 is screwed to the housing 1 at the edge with the interposition of a seal 3.
  • the drive motor 4 is flanged, the output shaft 5 of which projects into the housing 1.
  • the drive motor 4 shown is an electronically commutated DC motor. However, an AC motor can also be used.
  • the impeller 6 is fastened in a non-positive and / or positive manner.
  • the flow exit width of the impeller 6 is designated c.
  • the impeller 6 consists of the lower part 7 with the blades 8 integrally attached to it and the cover 9
  • the embodiment shown is the length of the blade 8 at the lower end, ie at the lower part 7, longer than at the upper end, ie close to the cover 9.
  • the impeller 6 can be made of metal or plastic.
  • the gaseous medium is axially, i.e. through opening 10 in the cover 2, sucked in and blown out radially (into the image plane in FIG. 1).
  • the blow-out opening is present as a rectangular aperture in the circular flange 11.
  • the effective shape of the radial fan according to the invention is illustrated in FIG.
  • the housing 1 has the spiral-shaped inner contour 12.
  • the dimensions a and b in the exemplary embodiment shown are 156 mm.
  • the blades 8 are curved backwards, as can be seen from the comparison with the direction of rotation of the impeller 6 illustrated by the arrow 13.
  • the shape of the blades 8 corresponds essentially to circular arcs. They are arranged in such a way on the lower part 7 that the entry angle ⁇ 1 has almost the same value as the exit angle ⁇ 2. In the exemplary embodiment shown, they have the value of 47 angular degrees.
  • the tongue region 15 the gap between the impeller 6 and the inner contour 12 of the housing near the blow-out opening 14 is referred to as the tongue region 15.
  • the tongue area is wedge-shaped.
  • Fig. 3 shows the impeller 6 from the suction side.
  • the blades 8 on the lower part 7 can be seen through the opening 10 in the cover 2.
  • Fig. 4 again shows that the blades are 8 circular sections.
  • the base points of the radius of all circular sections lie on the circle 16.
  • the diameter of the circle 16 is 98 mm.
