Definitions

  • the invention relates to an axial fan with reversible Flow direction according to the preamble of claim 1.
  • Modern axial fans are adjustable and performance-optimized Working machines, the mechanical energy in flow energy convert.
  • the controllability refers to the adjustability the speed of the impeller and the possibility of change the angle of attack of the blade with the aim of adjustment the slope of the lift to the current speed and Capacity.
  • the blades of the impeller are one
  • the axis of rotation is adjustable.
  • the impeller can also be used a trailing wheel can be combined, which is the kinetic energy existing swirl components are converted into static pressure.
  • a guide wheel causes one Change in the usable pressure increase of the fan.
  • the swirl generated counter-swirl or co-swirl
  • the fan characteristic curve is raised or lowered.
  • a thrust reversal as known from aircraft engines, does not apply as a solution because there is no axial fan energetically sensible operation is possible. It also works that there is only a countercurrent operation for a short time is recorded, but the reversal of direction in axial fans for a long time and from an energetically favorable point of view should be done.
  • the invention has for its object the generic Axial fan with reversible flow direction so too design that the same for a given volume flow aerodynamic performance, such as high pressure figure and high Efficiency, when operated in both directions becomes.
  • the guide vanes are just as adjustable as the blades of the impeller, that depending on the current requirements in the optimal Position can be brought. After reversing the air flow by adjusting the direction of rotation of the impeller and / or the blades is an operation of the axial fan in both Flow directions possible in such a way that the Energy consumption for equal air movements in both Flow directions is the same and close to that for Axial fans for one direction without reversibility lies.
  • the fan arrangement consists of a fan housing 1, that on one side via an intake manifold 2 with a Intake box 3 and on the other side over one Blow-out connection 4 is connected to a blow-out box 5.
  • a fan housing 1 Within the fan housing 1 is at a distance from the Housing wall and forming a flow channel 6 a Axial fan supported.
  • the axial fan contains a hub 7 with a streamlined inflow part 8, a cylindrical Middle part 9 and a streamlined outflow part 10.
  • a Impeller 11 arranged within the cylindrical middle part 9 of the hub 7 .
  • the impeller 11 consists of a Impeller hub 12, which with the cylindrical central part 9 of the hub 7 is aligned.
  • the impeller 11 is provided with blades 13 on its circumference stocked.
  • the blades 13 are about an axis of rotation rotatable, which runs radially to the impeller 11.
  • the Adjustment of the blades 13 takes place during operation or at standstill via a mechanical, electrical or hydraulic actuator.
  • the blades 13 are in Relative to the axis of rotation formed mirror-symmetrical. On the The actuator blades 13 can be rotated so far that according to the characteristic field for all throughput quantities and operating conditions optimal efficiencies can be achieved.
  • the Blades 13 are also rotated so that a Flow reversal occurs.
  • the intake manifold 2 for the blow-out nozzle and the blow-out nozzle 4 for Intake manifold is for example when using the axial fan in the ventilation of a Tunnels desirable if the fire gases close in a fire a certain air shaft or to the closer one Air shaft or tunnel exit are to be promoted.
  • the impeller 11 is driven by a drive motor 14, which is arranged as a built-in motor within the hub 7.
  • the Drive motor 14 is designed as an asynchronous motor and with a speed control.
  • the speed control serves also for setting optimal efficiencies different operating conditions. With a simple one
  • the direction of rotation of the asynchronous motor can be switched turning back. With the asynchronous motor, this also changes Direction of rotation of the impeller 11, so that with the adjustment of the Blades 13 also reverse this way Flow direction is reached.
  • the impeller 11 is inside the fan housing 1 fixed Vorleitrad 15 upstream and a fixed Nachleitrad 16 downstream. Both idlers 15, 16 are with Guide vanes 17, 18 are provided, which are preferably curved. The curvature can be caused by the fact that the Guide vanes 17, 18 consist of straight sections, which under butt at an obtuse angle.
  • the guide vanes 17 of the guide vane 15 are mirror-symmetrical to the guide vanes 18 of Nachleitrades 16 formed, the radial Center plane of the impeller 11 forms the plane of symmetry.
  • the guide vanes 17, 18 of the Vorleitrades 15 and Nachleitrades 16 are rotatably mounted about an axis of rotation 19. Because of this storage, they are at an angle to Flow direction adjustable.
  • the setting of the guide vanes 17, 18 takes place mechanically or electrically against the spring force a return spring 20 via an actuating lever 21 which on the Axis of rotation 19 attacks.
  • the control lever 21 is on the Fan housing 1 supported.
  • the setting of the guide vanes 17, 18 serves as well as the rotation of the blades 13 to set optimal efficiencies.
  • the guide vanes are made 17, 18 from a fixed section 22 and from a adjustable section 23.
  • the parting plane of the two sections 22, 23 of the guide vanes 17, 18 lies in the plane of the Guide vanes 17, 18 along the axis of rotation 19.
  • the adjustable Sections 23 of the guide vanes 17, 18 are each the impeller 11 facing.
