Abstract
Wentylator promieniowy z regulacją wydajności z kierownicą żaluzjową umieszczoną w skrzyni wlotowej, znamienny tym, że kształt skrzyni wlotowej jest niesymetryczny względem płaszczyzny (7) przechodzącej przez oś wirnika (6), a oś (8) kanału skrzyni wlotowej, nie przecina się z osią (6) wirnika i jest od niej odległa o odległość (B) większą niż 3% średnicy wylotu ze skrzyni (10), natomiast kierownicze łopatki (2) mają szkieletową profilu wygiętą i są ustawione wygiętą stroną wklęsłą w stronę kierunku napływu czynnika (1), a oś przynajmniej jednej ze skrajnych kierowniczych łopatek (3) jest położona w odległości (A) od ścianki kanału skrzyni wlotowej (4), mniejszej niż 1/3 najmniejszej odległości (T) pomiędzy osiami łopatek kierowniczych, natomiast płaszczyzna, w której leżą osie łopatek kierowniczych jest nachylona do osi (8) kanału skrzyni wlotowej pod kątem w granicach od 45 do 80°.Centrifugal fan with capacity control with a louvered steering wheel located in the inlet box, characterized in that the shape of the inlet box is asymmetrical in relation to the plane (7) passing through the rotor axis (6) and the axis (8) of the inlet channel does not intersect with the axis ( 6) the rotor and is distant from it by a distance (B) greater than 3% of the diameter of the outlet from the box (10), while the steering blades (2) have a skeletal bent profile and are set with a bent concave side towards the inflow of medium (1), and the axis of at least one of the extreme steering vanes (3) is located at a distance (A) from the wall of the inlet box channel (4), less than 1/3 of the smallest distance (T) between the axes of the steering vanes, while the plane in which the axes of the vanes lie steering is inclined to the axis (8) of the inlet duct at an angle between 45 and 80 °.
