Abstract
The utility model discloses a cooling tower fan, comprising an impeller and a driving motor, wherein the impeller comprises a blade with a hollow interior and a hub provided with a shaft hole for fixing a rotary shaft of the motor, the blade is internally and uniformly distributed with a first wing beam close to the outer end part of the blade, and a second wing beam along the axial direction, and a gap is arranged between two sides of the first and second wing beams and the inner wall of the blade. The cooling tower fan disclosed by the utility model is simple in structure and convenient to process, thus improving the dynamic stability of the fan, greatly improving the rotating speed, improving wind resisting capacity and prolonging the service life of the equipment.
Description
Technical field
The utility model relates to a kind of blower fan of cooling tower.
Background technique
At present, lifting along with energy-conservationization of domestic cooling tower, the factors such as raising of water yield Processing capacity, the more and more large-scale change of blower fan of cooling tower is along with the increase of fan capacity, the diameter of the blade of blower fan is also along with increase, under the situation of the bearing capacity that guarantees fan blade, the stability when just being difficult to guarantee fan operation and good aeroperformance change to improve its operation stability though also there is the structure of some blower fan low blades to make at present, but it is complex structure often, and manufacturing process is loaded down with trivial details.
Summary of the invention
The utility model provides a kind of simple in structure in order to overcome the deficiencies in the prior art, stable height, the blower fan of cooling tower of long service life.
To achieve these goals, the utility model is by the following technical solutions: a kind of blower fan of cooling tower, comprise impeller and drive motor, impeller comprises blade and the wheel hub of inner hollow, wheel hub is provided with the fixing axis hole of rotating shaft of power supply machine, be evenly distributed with first spar and second spar in the described blade vertically respectively, first spar is provided with the gap near the outer end of blade between the both sides of first spar and second spar and the blade inwall.
Further, described first spar is arcuate structure.
Further, be provided with through hole between the lower end surface of described second spar and wheel hub.
Described first spar and second spar and blade up and down between the inwall by being adhesively fixed.
In sum, the utility model has following advantage: this blower fan of cooling tower is simple in structure, and is easy to process, improved the dynamic stability of blower fan, and rotating speed improves greatly, and wind loading rating also improves, and prolonged the working life of equipment.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, the technological scheme among the utility model embodiment is carried out clear, complete description.
As shown in Figure 1, a kind of blower fan of cooling tower, comprise impeller and drive motor 1, impeller comprises blade 3 and the wheel hub 2 of inner hollow, wheel hub 2 is provided with the fixing axis hole 21 of rotating shaft 12 of power supply machine 1, be evenly distributed with first spar 31 and second spar 32 in the described blade 3 vertically respectively, first spar 31 is near the outer end of blade 3, be provided with the gap between the both sides of first spar 31 and second spar and blade 3 inwalls, after former and later two spars are set, can increase aeroperformance and the dynamic stability of blower fan, when improving rotating speed, also prolong the working life of blower fan.Described first spar 31 is arcuate structure, can increase the degree of balance, is provided with through hole 4 between the lower end surface of described second spar 32 and wheel hub 2, can be so that the discharging of the ponding on blade and the wheel hub also can increase the circulation of air-flow.Described first spar 31 and second spar 32 and blade 3 up and down between the inwall by being adhesively fixed.To guarantee when bonding that two spars all are to arrange along the axial direction of blade.
Obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
