Definitions

  • the invention relates to a radial fan with a housing and an axially arranged therein Air inlet, an air outlet, a radially and axially expanding Pressure chamber and a hollow cylindrical pot area for inserting a wheel.
  • Generic radial fans are used to air, another gas such as methane or suck in and further convey an air-gas mixture from a working environment, where both the flow rate and the pressure of the pumped medium increases.
  • the invention is based on a radial fan with a housing and an axially arranged therein Wheel directed, the housing having an axial air inlet, an air outlet, a floor area with a floor reference surface orthogonal to the axis and has a spiral pressure space guided radially around the wheel, the extends to the air outlet; and the wheel facing the air intake Cover plate and a support plate; which is characterized in that the spiral pressure chamber both in the radial direction from the axis as well expanded in the axial direction towards the air outlet, whereby the axial expansion extends over at least 180 ° of the spiral circumference; and in the bottom area in axial A hollow cylindrical pot area is sunk in the direction beyond the floor reference surface is in which the wheel is inserted so that an inside of the support plate of the Rads runs flush with the ground reference surface.
  • the basic wheel blower according to the invention is characterized by two aspects. This is, on the one hand, the flush closure of the air outlet openings of the impeller the so-called ground reference area. This is generally defined as the area of the Bottom if there are no depressions in the form of the hollow cylindrical pot and (optional) would have the pressure chamber expansion. The one sucked in by the wheel during operation Air can thus go directly into the airspace without having to overcome an obstacle enter. On the other hand, this arrangement prevents the Air thrown out of the wheel excessively under the wheel's wheel can reach what would reduce the efficiency of air production.
  • Another aspect of the invention is that of widening to the air outlet opening Optimizing the print room.
  • Pressure spaces known that extend in the radial direction, i.e. removing from the bike, expand towards the air outlet.
  • the axis of rotation is arranged under the axis or axially in the sense of the present invention of the wheel or the imaginary center of rotation of the air in a spiral To understand pressure room.
  • the floor reference surface is an imaginary surface, which is the interior surface of the housing would be if the bottom had no recesses, such as the hollow cylindrical one Pot and / or would have the axial expansion of the pressure chamber.
  • the Ground reference surface is used as a reference surface to describe various elements of the radial fan according to the invention can be used.
  • the radial direction in For the purposes of the present invention, one is radially extending away from the axis Direction.
  • the axial direction is one parallel to the axis in one of two possible directions direction.
  • Tangential directions in the sense of the present invention are those that are tangents represent an intended or actual scope.
  • the wheel is advantageously inserted into the hollow cylindrical pot area in such a way that between the circumference of the supporting disc, which is completely sunk in the pot area and the side wall of the pot area has the smallest possible space is whose width results from precision movements of the wheel during turning operation results.
  • the pressure space expands advantageously in the axial direction over the floor reference area out. In this way, the expansion of the pressure chamber comes next to the hollow cylindrical one Pot area to lie because both extend in the same axial direction.
  • the pressure space is delimited by a wall in the radial expansion area, which Ground boundary area defined.
  • the pressure chamber can also extend in the axial direction into the cover area of the housing.

  • a tongue is arranged in the housing, which is essentially in extends in the circumferential direction into the pressure chamber, and one formed by the tongue Leading edge in lateral projection over its course different angles with the Floor reference plane of the fan forms.
  • Such a tongue basically serves the separation of the pressure space from the rest of the housing space, i.e. the area of the housing in which there is a pressure which is lower than that at the end of the Pressure chamber in front of the air outlet.
  • the tongue is intended to prevent a short circuit flow. This measure also completes the funnel shape of the pressure chamber and additionally increases the air output.

  • the tongue would best do its job of preventing short circuit flow meet if it were arranged as close as possible to the wheel. This would, however the disadvantage of enormous noise must be accepted. Therefore, the general aim is to design the tongue so that the tongue is as small as possible or optimized noise development with the best possible prevention of the short-circuit flow is achieved.
