Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
Fig. 1 is the front view of super high power type draught fan impeller embodiment of the present invention, and Fig. 2 is super high power type blower of the present invention
The side view of impeller side view embodiment, Fig. 3 are that vane embodiment shows in super high power type draught fan impeller side view of the present invention
It is intended to, Fig. 4 is the cross-sectional view of super high power type draught fan impeller side view embodiment of the present invention, as shown, a kind of super high power
Type draught fan impeller, including shroud 1, hub disk 2 and blade 3, for blade 3 between hub disk 2 and shroud 1, shroud 1 is parallel with hub disk 2
Setting, hub disk 2 are plane integral structure, and hub disk 2 and shroud 1 are securely attached to together by blade 3.Shroud 1 is structure as a whole,
And including upper surface 11 and lower end surface 12, blade 3 is located at the inside of upper surface 11, and the internal diameter of upper surface 11 is equal to 2 radius of hub disk
2/3rds, the radius of lower end surface 12 is equal to the radius of hub disk 2, the circular arc to concave between upper surface 11 and lower end surface 12
Blade 3 is closely fixed on inside by shape structure, shroud 1 and hub disk 2, and the distinguished and admirable entrance from upper surface 11 enters, then in leaf
It is screwed out under the action of piece 3.
Blade 3 is smooth integral structure, and the thickness uniformity of blade 3, the quantity of blade 3 is 12, and uniform
It is distributed on hub disk 2, the setting of blade guarantees to screw out sufficiently strong distinguished and admirable.The outer side edges 31 of blade 3 are connection shroud 1 with after
The outer side edges 31 of the vertical edge of disk 2, blade 3 provide a supporting role.The bottom edge 33 of blade 3 is the arc knot being fixed on hub disk 2
Structure, center of circle radian is 30-50 ° on the corresponding hub disk 2 in 3 bottom edge of blade 33, the vertex 34 on 3 bottom edge 33 of adjacent blades, 35 and of basic point
The center of circle of hub disk 2 is located on the same line, and the distinguished and admirable trend along blade 3 enters blower, and it is strong to strengthen blower gas chamber wind pressure
Degree prevents the air return that external resistance is generated in operation.The vertex 34 on 3 bottom edge 33 of blade is distributed in a concentric circles of hub disk 2
On, the radius of concentric circles is the one third of 2 radius of hub disk.
The first tangent line that blade top margin 36 is corresponded in 3 outer side edges 31 of blade is located at second tangent line on corresponding 3 bottom edge 33 of blade
Outside, correspond in 3 outer side edges 31 of blade the first tangent line of 3 top margin 36 of blade and second tangent line on corresponding 3 bottom edge 33 of blade it
Between angle be 30-40 °, 3 outer side edges 31 of blade more slope inwardly compared to 3 top margin 36 of blade, make full use of matched performance number,
