Abstract
The utility model relates to a multi-wing centrifugal vane which is composed of a wheel pan, a wheel cover and blades, wherein, the bottom surface of the wheel pan and the wheel cover are round and are mutually parallel; the blades are positioned between the wheel pan and the wheel cover and are mutually parallel; the diameter of the wheel cover is smaller or larger than the diameter of the bottom surface of the wheel pan, and the blades are arranged slantways from the wheel pan to the wheel cover correspondingly to a rotary center line of the blades. The noise produced by the multi-wing centrifugal vane is effectively decreased under the condition of improving or not reducing the air volume performance.
Description
The utility model relates to the multi-wing centrifugal impeller that a kind of ventilation is used.
Traditional multi-wing centrifugal enclosing cover for impeller and wheel disc bottom surface equal diameters, blade is between wheel cap and wheel disc, two ends are separately fixed at wheel disc and wheel covers, blade is parallel to the spin axis of impeller, dispose a spiral case in its periphery during this impeller practical application, traditional spiral case inwall molded lines is along axial direction and impeller rotating center line parallel, the structure that this spiral case cooperates with impeller, gap between the impeller of rotation and static spiral case is along not variation of axial direction, concerning the individual blade of impeller, blade is the minimum clearance by impeller and spiral case simultaneously along the different parts of axial direction, because non-permanent interference and blade between impeller and the spiral case have periodically just produced a kind of revolution noise by the minimum clearance between impeller and the snail tongue, simultaneously because the minimum clearance between impeller and the snail tongue is constant on whole axial direction, and the individual blade of impeller is at one time by this gap, make the noise stack of same frequency and produce resonance peak, cause rotational noise higher relatively, become the main noise of multi-wing centrifugal fan.
The object of the present invention is to provide a kind of air quantity characteristic increase or undiminished situation under noise is reduced the multi-wing centrifugal impeller.
The utility model is to realize like this, it is made of wheel disc, wheel cap and blade, wheel disc bottom surface and wheel cap are circular and are parallel to each other, blade is between wheel disc and wheel cap, two ends are separately fixed at wheel disc and wheel covers, be parallel to each other between blade, the diameter of wheel cap can less than or greater than the diameter of wheel disc bottom surface, the rotation centerline tilted configuration of blade relative impeller from the wheel disc to the wheel cap.
The blade that the utility model makes the multi-wing centrifugal impeller with respect to the spin axis tilted configuration of impeller and make blade along impeller shaft to different with the gap of spiral case and snail tongue from the wheel cap to the wheel disc, alleviated the wake effect that produces owing to non-permanent interference effect between blade and the housing, make the noise that produces between blade and the housing that certain phase difference be arranged, the resonance noise of having avoided the stack of same frequency noise to be brought, thereby reduced the rotational noise of impeller.Dispose by certain angle tilt in sense of rotation when shape stretches because blade is in line on its length direction again, make same blade along its axially the different time by the minimum clearance between impeller and the housing, so also alleviated the wake effect that produces owing to non-permanent interference effect between blade and the housing, can avoid producing at one time the noise of same frequency and the resonance peak that stack brought thereof, thereby reduce the rotational noise of impeller.
The utility model is described in further detail below in conjunction with drawings and Examples.
