Description

Axial-flow blower fan blade
Technical field
The utility model relates to blower fan technical field, particularly relates to a kind of axial-flow blower fan blade.
Background technique
The blade of axial-flow blower fan blade and blade wheel hub are separated types in the market, personnel are needed to assemble, shortcoming is that concentricity is poor, wind speed low-intensity low noise is large, and on market, fan blade diameter and the number of blade do not reach rational ratio with stator blade number, and shortcoming is that wind speed is low and complete machine electric current is large, fan blade is beated larger, the Spielpassung of fan blade and casing is comparatively large, and be unfavorable for air output, air output is large compared with little noise.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of axial-flow blower fan blade, simple and reasonable, blade and wheel hub are integral types, favourablely improve concentricity in blade and intensity, improve air quantity and reduce noise, rational blade quantity and blade diameter coordinate rational guide vane quantity, can improve fan blade efficiency and wind speed.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of axial-flow blower fan blade, comprise: blade part and the guide vane portion being arranged on blade part rear, described guide vane portion comprises 5 guide vanes, described blade part comprises wheel hub and is arranged on the multiple blades on wheel hub, described blade and wheel hub are integral types, and the quantity of described blade is 12, and the diameter of the excircle that described 12 blade outward edges form is 84 millimeters.
In the utility model preferred embodiment, the diameter of described wheel hub is 40 millimeters.
In the utility model preferred embodiment, described guide vane portion also comprises center drum, and one end of described guide vane is fixed on center drum, and the other end is fixed on the outer tube inner wall of axial-flow blower.
The beneficial effects of the utility model are: the utility model axial-flow blower fan blade, simple and reasonable, blade and wheel hub are integral types, favourablely improve concentricity in blade and intensity, improve air quantity and reduce noise, rational blade quantity and blade diameter coordinate rational guide vane quantity, can improve fan blade efficiency and wind speed.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:

Following table is the performance data in different leaves quantity and different guide vane quantity situation:
Model Flow (Kg/S) Air horsepower (W) Outlet total head (Pa) Fan efficiency
Fan 11+stator 7 0.1792 317.81 1195.661 55.04%
Fan 12+stator 5 0.2064 458.55 1586.598 58.36%
Preferably, the diameter of described wheel hub 2 is 40 millimeters.
Described guide vane portion also comprises center drum, and one end of described guide vane 1 is fixed on center drum, and the other end is fixed on the outer tube inner wall of axial-flow blower.
The beneficial effects of the utility model are: the utility model axial-flow blower fan blade, simple and reasonable, blade and wheel hub are integral types, favourablely improve concentricity in blade and intensity, improve air quantity and reduce noise, rational blade quantity and blade diameter coordinate rational guide vane quantity, can improve fan blade efficiency and wind speed.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
