Definitions

  • the present invention relates to a radial impeller, in particular for use in gas blowers with a steep fan characteristic curve.
  • the EP 0 410 271 B1 describes a radial fan for conveying a gaseous medium in a device with high flow resistance, which is in particular a burner in a gas boiler. Such burners have a relatively high flow resistance, which is of the order of 200 Pascal or more.
  • the medium to be conveyed may be air or a combustible gas-air mixture.
  • the blower or its blower wheel must therefore be designed for a steep pressure-volume flow characteristic. This means that pressure changes should be accompanied by only small changes in the volume flow.
  • the known fan has for this purpose an impeller whose diameter is more than ten times its flow outlet width.
  • first cover plate lower part
  • second cover plate circular, flat plate-shaped lid
  • the present invention has for its object to provide a Radialgebläserad, which is particularly suitable for a gas burner fan with steep curve in a simple and economical manner to produce.
  • annular cover plate which has a width R D , which is measured from the edge of the suction port is smaller than the AbstandRand- suction to discharge opening - peripheral edge.
  • the width such that it is substantially half the blade length measured from the intake opening.
  • This particular embodiment also allows a production of the impeller as a one-piece molded part, being considered as particularly favorable an embodiment in which the support disc is annular and has a ring width, which is substantially the dimension outer edge cover plate to exit opening-Umfangsrand (2-3 '. ) is.
  • this ring width is substantially half a blade length, the air flow in the exit region still a guide can be issued, so that the Scherbreibung between the rear housing wall and the flow is limited to a reduced range.
  • the two disc rings namely that of the cover disc and that of the support disc, either overlap in the projection in the direction of the axis of rotation as required, form a gap between them or subsequently complement each other to form a circular area.
  • An advantageous flow course can be achieved in that the hub body has a height that corresponds to measured from the plane of the rear support plate substantially half the wheel depth.
  • a cone is formed on the hub body to the flow side, wherein the cover plate and the cone of the hub in cross-section A-A have a substantially parallel course. As a result, a favorable flow profile is achieved in the input region of the wheel.
  • a region is formed whose flow surface is substantially parallel to the plane of rotation.
  • the flow surface of the outer peripheral portion is arranged in a plane which is located with respect to the flow channel inwardly than the surface of the outer support disc defining the flow channel, d. That is, the support disk can be made thinner than the thickness of the outer peripheral portion of the cone.
  • An advantageous embodiment can be designed so that the blades are axially wider in the intake area than in the outflow area.
  • At least one intermediate blade is arranged between the blades essentially in the region of the width of the carrier disk.
  • each case two intermediate blades are arranged in pairs.
  • the intermediate blades have a radial extension which essentially corresponds to the distance between the outer circumference of the cover disk and the outer circumference of the rear support disk.
  • the intermediate blades are held exclusively on the rear support plate.
  • This embodiment particularly facilitates the formation of the radial impeller as a one-piece cast part.
  • a radial impeller 1 consists of a plurality of distributed over the circumference arranged radial blades 2, seen in the radial direction of an inner inlet region 4 to an outer outlet region 6 extend.
  • the blades 2 have radially inner end edges 8, which are located on an imaginary, approximately cylindrical, but especially conical surrounding the inlet region 4 and in the axial inflow direction (see the arrow E in FIG Fig. 1 and 4 to 6 ) seen in the inlet region 4 in the tapered surface lie.
  • the blades 2 also have outer end edges 10.
  • radial Startsmungskanäle 12 are formed with a substantially radial outflow direction A.
  • the blades 2 extend axially, ie viewed in the direction of a rotation axis 14, between an inlet side 16 and an axially opposite hub side 18 (see the sectional views in FIG 4 to 6 ).
  • the blades 2 are furthermore connected only on their inlet side 16 over their radial extent to the outlet region 6 with a cover disk 20 which has a central inlet opening 22 opening into the inlet region 4.
  • the blades are connected only with their radially inner end regions with a central hub 24, so that the flow channels 12 are formed open on this side in the axial direction.
  • the blades 2 thus have free side edges 26 on this side.
  • the blades 2 and the cover plate 20 has an outer impeller diameter D, which is at least ten times an existing in the exit region 6, axially measured flow outlet width B of the blades.
  • the axially measured inner flow inlet width C of the blades 2 in the inlet region 4 is preferably greater than the outer flow outlet width in the outlet region 6 (cf., for example, FIG Fig. 4 ).
  • a further non-inventive embodiment are with the cover plate 20 in each radially disposed between adjacent blades 2 areas intermediate blades 28 are connected (see in particular Fig. 1 and 2 ). These intermediate blades 28 extend from the outer circumference of the cover plate 20 only over part of the radial extent of the cover plate 20 and terminate at a radial distance from the hub 24. This can best be seen in Fig. 2 detect. In the illustrated embodiment, between each two adjacent blades 2 only one intermediate blade 28 is provided, but it can also be provided each two or more intermediate blades 28, which can then be designed with the same or different radial length.
  • the radial impeller 1 can be advantageously prepared as a one-piece molding made of plastic, preferably made of a plastic having such antistatic properties that during operation static charges avoided or derived via a not shown housing. This contributes to a high degree of application safety, especially with regard to the preferred application for conveying combustible gas-air mixtures, by avoiding ignition by sparking.
  • the blades 2 and the intermediate blades 28 are formed in the radial direction with respect to the direction of rotation 30 is curved backward.
  • the blades are arranged such that their entry angle is approximately between 30 ° and 45 ° and their exit angle is approximately between 45 ° and 90 °. To explain this angle is on the EP 0 410 271 Referenced.
  • an embodiment with forward curved or at the exit region 6 radially ending blades 2 and intermediate blades 28 is possible.
  • the hub 24 consists of an outer disk portion 32 and a central, to be connected to a shaft not shown bearing portion 34, in particular in the form of a short pipe socket.
  • the disc portion 32 is connected at its radially outer periphery with the inner, the inlet portion 4 facing end portions of the blades.
  • the disc portion 32 of the hub 24 is projecting from its outer peripheral region connected to the blades 2 such in the inlet region 4 and in the direction of the inflow opening 22 of the cover plate 20 projecting convexly or cup-shaped, for example, that the hub 24 -.
  • Fig. 1 please refer in particular Fig.
  • blower-functional elements such as bearing elements, motor or rotor parts and / or the like.
  • FIG. 2 shows, (at least) the intermediate blades 28 are connected to the cover plate 20 via a respective transition reinforcement 38 formed in the blade root area. This ensures, despite the connection-free, spaced from the hub 24 embodiment, a sufficient stability of the intermediate blades 28th
  • the blades 2 and the intermediate blades 28 in its radially outer and the cover plate 20 axially opposite region for mechanical reinforcement via a circumferential, integrally molded ring member 40 are connected.
  • the cover disk 20 in the region of the inflow opening 22 has a nozzle-like edge 42 in the flow direction.
  • radial impeller 2-1 has an annular cover plate 2-9, which surrounds the suction 2-7 annular. Usually, a circular suction opening 2-10 is formed on the cover plate 2-9, which is surrounded by a circumferential opening lip 2-10 '.
  • the radial impeller 2-1 further includes a hub body 2-2 and a peripheral edge 2-3.
  • the hub body 2-2 has on its side facing the suction opening 2-10 a cone 2-2 'on.
  • the impeller 2-1 is equipped with blades 2 - 6 substantially extending radially from the hub body 2 - 2 to the peripheral edge 2-3.
  • the vanes define an intake region 2-7 and an outflow region 2-8.
  • the annular cover plate 2-9 has a width R D , which measured from the edge of the suction port (2-10) is half the distance edge-outlet opening circumference 2-3.
  • the width R D thus corresponds substantially to half the blade length measured along the upper peripheral edge of the blade 2-6.
