Abstract

The invention discloses a kind of centrifugal blower fan blade wheels, it includes front ring (1) and rear circle (2), multiple blades (3) are welded and fixed between front ring and rear circle, the lateral section of the blade is parallel with airflow direction, and longitudinal section of the blade is in the arcuation waveform of bionical humpback shell shape, the lateral section of the blade is arc-shaped in bionical humpback dorsal fin shape, and the middle part of the blade is made to form protrusion.The structure of centrifugal blower fan blade wheel of the present invention changes the position that vortex is detached from blade exit, increase the distance between center of vorticity, it is suppressed that vortex is detached from the disturbance to flowing to reduce aerodynamic noise, has bionical noise reduction, and aerodynamics is excellent, it is high-efficient the features such as.

Description

A kind of centrifugal blower fan blade wheel
Technical field
The present invention relates to centrifugal blower, especially a kind of centrifugal blower fan blade wheel.
Background technique
Centrifugal blower using relatively broad, and impeller is the important composition component of centrifugal blower, the rotation of impeller, is driven Whether gas flowing, the setting of structure rationally directly affect the overall performance of blower.Current domestic centrifugal blower fan blade wheel Blade is commonly straight plate shape, although workmanship is simple, in blower operation process, and impeller outlet " jet stream-tail easy to form The disadvantages of mark " phenomenon causes noise big, low efficiency.
Summary of the invention
The technical problem to be solved by the present invention is in existing centrifugal blower operation process, impeller outlet formation " is penetrated The problems such as stream-tail " phenomenon, causes noise big, low efficiency, it is excellent, high-efficient to provide a kind of bionical noise reduction, aerodynamics Centrifugal blower Bionic impeller.
In order to solve the above technical problems, the technical scheme adopted by the invention is that: a kind of centrifugal blower fan blade wheel, including front ring With rear circle, multiple blades are welded and fixed between front ring and rear circle, the lateral section of the blade is parallel with airflow direction and described Longitudinal section of blade is in the arcuation waveform of bionical humpback shell shape, and the lateral section of the blade is in bionical humpback Dorsal fin shape it is arc-shaped, so that the middle part of the blade is formed protrusion.
The dorsal fin shape of the bionical humpback of blade transverse direction section of the invention, the dorsal fin of humpback is lower, and back is unlike it His whale class is straight like that, but arches upwards, forms a graceful curve, studies have shown that such configuration of surface has Reduce the function of running resistance and noise.In addition the shell shape of the bionical humpback of blade longitudinal direction section, shell are able to bear sea The impact of water year in year out, waveform shell are also important reason.
The blade of centrifugal blower fan blade wheel of the present invention is wavy shaped configuration, which changes what vortex at blade exit was detached from Position increases the distance between center of vorticity, it is suppressed that vortex is detached from the disturbance to flowing to reduce aerodynamic noise, has imitative Raw noise reduction, and aerodynamics is excellent, it is high-efficient the features such as.
Detailed description of the invention
Fig. 1 shows centrifugal fan impeller structure figures of the present invention.
Fig. 2 indicates blade vertical structure figure of the present invention.
Fig. 3 indicates blade lateral junction composition of the present invention.
Specific embodiment
Structure of the invention is illustrated below with reference to Fig. 1-Fig. 3.
Referring to Fig. 1, centrifugal blower Bionic impeller of the present invention, including front ring 1 and rear circle 2, it is fixed between front ring 1 and rear circle 2 There are multiple blades 3, blade 3 is fixed together in a welding manner with front ring 1, rear circle 2.
Referring to fig. 2, longitudinal section of Fig. 3, blade 3 are wavy, are arc-shaped in lateral section, effective bionical humpback Dorsal fin and shell shape.
