Abstract
The utility model discloses a large diameter cooling tower fan blade. The large diameter cooling tower fan blade is composed of a blade front edge tipping, a working face shell, a blade wing spar shaped like a Chinese character 'ji' and a non-working face shell, wherein the blade wing spar shaped like the Chinese character 'ji' is arranged between the blade working face shell and the non-working face shell, installed along the axial direction of the blade and fixed with the blade into a whole. The front end of the fan blade is provided with the blade front edge tipping wrapped by hygrometric state glass fiber cloth. Compared with an existing blade, the large diameter cooling tower fan blade improves wind resistance ability and dynamic stability and prolongs service life of the blade.
Description
Technical field
The utility model relates to a kind of fan blade, particularly a kind of major diameter blower fan of cooling tower blade.
Background technique
At present; Along with energy-conservationization of domestic induced cooling tower, improve the water yield processings, reduction expense, reduce the continuous lifting of floor space requirement; The maximization of cooling tower and blower fan, energy-conservationization have become a current main developing direction and inexorable trend, and along with the increase of fan capacity, the fan blade diameter also increases thereupon; The bearing capacity of fan blade improves; Keep blower fan to have good aeroperformance and dynamic stability, the design and processes difficulty of fan blade increases, to the structural design of fan blade, adopt aspect such as material to propose new requirement.Major diameter blower fan of cooling tower blade is a kind of high tenacity fan blade that the actual demand according to the scene manufactures and designs.
Summary of the invention
The purpose of the utility model is to overcome that the narrow and long blade stiffness that produces is not enough owing to blade, and the phenomenon of blade shape face local buckling, and a kind of in light weight, intensity is high, the life-span is grown major diameter blower fan of cooling tower blade is provided.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of major diameter blower fan of cooling tower blade, and it is made up of blade inlet edge bound edge, working surface housing, a few word spars of blade, non-working surface housing; A few word spars of blade are arranged between front side of vane housing and non-working surface housing; A few word spars of blade are installed along the axial direction of blade, and with vanes fixed be one; At the front end of fan blade, a blade inlet edge bound edge with hygrometric state glass fiber cloth parcel is arranged.
Adopt between a few word spars of above-mentioned described blade and working surface housing and the non-working surface housing and be adhesively fixed.
Owing to increased a few word spars of blade in the inside of novel fan blade, improved wind loading rating and dynamic stability, prolonged blade working life.
Description of drawings
Fig. 1 is a major diameter blower fan of cooling tower blade schematic representation;
Fig. 2 is major diameter blower fan of cooling tower blade section figure;
Fig. 3 is a few word spar of major diameter blower fan of cooling tower blade schematic representation.
In the drawings, 1-fan blade, 2-blade inlet edge bound edge, 3-working surface housing, a few word spars of 4-blade, 5-non-working surface housing.
Embodiment
Below in conjunction with accompanying drawing the structure of major diameter blower fan of cooling tower blade is done further explain:
By Fig. 1,2,3 visible; Major diameter blower fan of cooling tower blade 1 is made up of a few word spar of blade inlet edge bound edge 2, working surface housing 3, blade 4, non-working surface housing 5, between the working surface housing 3 of blade and non-working surface housing 5, is provided with a few word spars 4 of blade.
Adopt between a few word spars 4 of blade and the housing to be adhesively fixed, fixedly the time, a few word spars 4 of blade must be installed along the axial direction of blade 1, and become one with blade; The blade that contains a few word spars 4 because of a few word spar torsional angle φ change with blade shell, has greatly increased the anti-twisting property of blade.
At the front end of fan blade 1, a blade inlet edge bound edge 2 with hygrometric state glass fiber cloth parcel is arranged, leading edge bound edge 2 can be after the blade integral moulding be accomplished; Implement with hygrometric state glass fiber cloth parcel; Size does not have strict demand, and appropriateness is good, to avoid the blade inlet edge cracking.
Make blade 1 main raw material(s) and adopt alkyd resin, the non-twist glass fiber cloth of grid alkali-free; On manufacturing process; The moulding separately in blade mold respectively of working surface housing, non-working surface housing; And leave bonding tongue in the leading edge of non-working surface housing, a few word spars 4 of blade the spar in-mold molding solidify accomplish after, use clay and in type non-working surface bonding again; Guarantee a few word spars of blade 4 positions when bonding along the axis of runner blade direction, become blade with the working surface housing 3 of molded completion and a few word spar 4 usefulness clay of non-working surface housing 5 and blade are bonding again.
Embodiment is following:
LF104-1000G type blower fan of cooling tower blade adopts said structure and material, 10.36 meters of diameters, and the long 5090mm of blade, wide 800mm, blade root is the cylindrical section of φ 200, blade word spar 4698 * 290 * 166mm.
