Abstract
The invention discloses a fan impeller which comprises an impeller cover and an impeller dish, wherein the impeller cover and the impeller dish are connected together through vanes and the impeller dish is provided with a plurality of openings which are arranged uniformly and used for reducing the weight of the impeller dish. Compared with the prior art, the openings which are arranged uniformly on the impeller dish can effectively reduce the weight of the impeller dish, so that the power of a motor can be reduced to achieve the purpose of energy saving, meanwhile, the strength of the impeller dish cannot be affected due to the thickness of the impeller dish is not changed, if the number and size of the openings can be under effective control.
Description
Technical field
The invention belongs to the technical field of blower fan, is a kind of draught fan impeller concretely, especially a kind ofly can make the more energy-conservation draught fan impeller of blower fan.
Background technique
Blower fan is widely used in industrial production and the daily life fields such as aviation, coal, electric power, metallurgy, electronics, automobile, air-conditioning as a kind of turbomachine of carrying air.Impeller is the most important parts of centrifugal blower, and its function is static energy and the kinetic energy that mechanical energy is converted into gas.
Blower fan moves by the motor driving impeller, the watt level of motor is by the weight of the wheel speed of this Fans and impeller, we know that the flow of blower fan and pressure size are that rotating speed by impeller determines, so the rotating speed of impeller also is certain under the certain prerequisite of flow and blast, we could only reduce by the gross mass that reduces impeller the power of motor, reach energy-conservation purpose! Also reach and reduce the blower fan manufacture cost, improve the competitive ability of enterprise! Centrifugal force when the decline of impeller gross mass has also reduced the impeller operation has improved the impeller Operation safety! From cost, energy-conservation and secure context, it all is the most feasible reducing impeller weight, at present, direct and the simplest method is the purpose that reaches weight reduction by attenuate impeller thickness of slab, is 201020605807.5 Chinese utility model patent such as application number, discloses a kind of not uniform thickness draught fan wheel disc, it is characterized in that: described not uniform thickness draught fan wheel disc uneven thickness, the thickness at described not uniform thickness draught fan wheel disc edge is less than the wheel disc thickness of remaining part.
But we know the harmfulness of blower fan accident, and the consequence that attenuate impeller thickness of slab must bring the intensity of original impeller to descend has so just increased the possibility that accident occurs! So can not simply reach the purpose of weight reduction by attenuate impeller thickness of slab!
Summary of the invention
The present invention is directed to deficiency of the prior art, provide a kind of and made blower fan running more energy-conservation and can not affect the draught fan impeller of impeller intensity.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of draught fan impeller, comprise wheel cap and wheel disc, described wheel cap and described wheel disc link together by blade, it is characterized in that: offer some equally distributed openings be used to alleviating described wheel disc weight on the described wheel disc.The equally distributed opening that the present invention offers at wheel disc can effectively reduce the weight of wheel disc, thereby reduce the power of motor, reach energy-conservation purpose, simultaneously, because the thickness of wheel disc does not change, under the prerequisite that quantity and size to opening control effectively, its intensity can not be affected yet.
As preferably, above-mentioned opening is the hole that is arranged on described wheel disc middle part.
As another preferred version, above-mentioned opening is the breach that is arranged on described wheel disc edge.The breach that is arranged on the wheel disc edge is at first processed more convenient, and can not affect the whole using effect of impeller, the more important thing is that at the easy dust stratification of blade end in the past, and the blade end that is arranged so that of breach of the present invention is difficult for dust stratification.
In order to obtain better technique effect, further technical measures also comprise: all have a described breach between per two adjacent described blades, described breach ecto-entad dwindles gradually, and its opening direction is consistent with the vane rotary direction.The breach of the technical program and the flow direction of wind adapt, and more are conducive to dust and pass through from indentation, there, make the better effects if of removing dust.
Further, the edge of above-mentioned breach is for being the arc of " colluding " shape, and this arc comprises the first segmental arc near the end of described blade, away from the second segmental arc of this blade and the bending section that connects described the first segmental arc and described the second segmental arc.The technique effect of this programme is so that remove the effect of the dust on the blade and further optimize.
For the intensity that guarantees impeller in weight reduction is not affected, the sum of area of all above-mentioned breach is less than or equal to described 20 percent of the disc area of taking turns.Because wheel disc is uniform thickness everywhere, therefore, the weight of the material of the indentation, there of removing on the wheel disc is equivalent to former 20 percent of the disc thickness of taking turns, and the weight of wheel disc accounts for 50 percent of whole impeller weight usually, therefore, the impeller of this programme is compared the weight that original impeller has alleviated ten Percent.
Compared with prior art, the present invention has following beneficial effect: the equally distributed opening that the present invention offers at wheel disc can effectively reduce the weight of wheel disc, thereby reduce the power of motor, reach energy-conservation purpose, simultaneously, because the thickness of wheel disc does not change, under the prerequisite that quantity and size to opening control effectively, its intensity can not be affected yet.

Embodiment
A kind of draught fan impeller comprises wheel cap 1 and wheel disc 2, and described wheel cap 1 and described wheel disc 2 link together by blade 3, offers some equally distributed openings be used to alleviating described wheel disc 3 weight on the described wheel disc 3.
Above-mentioned opening is the hole 31 that is arranged on described wheel disc 3 middle parts, be provided with 1 hole 31 between per two adjacent blades 3, the area in each hole 31 is all identical, and it is shaped as circle in the present embodiment, and the position in hole 31 is take the position of centre of gravity that do not affect wheel disc as prerequisite.
A kind of draught fan impeller comprises wheel cap 1 and wheel disc 2, and described wheel cap 1 and described wheel disc 2 link together by blade 3, it is characterized in that: offer some equally distributed openings be used to alleviating described wheel disc 3 weight on the described wheel disc 3.
Above-mentioned opening is the breach 32 that is arranged on described wheel disc 3 edges, and all has a described breach 32 between per two adjacent described blades 3, and described breach 32 ecto-entads dwindle gradually, and its opening direction is consistent with the vane rotary direction.Same, the shape of each breach 32, size are all identical, and its position is also take the position of centre of gravity that do not affect wheel disc as prerequisite.
Specific to present embodiment, the edge of above-mentioned breach 32 is the arc of " colluding " shape, this arc comprises the first segmental arc 32a near the end of described blade 3, away from the second segmental arc 32c of this blade 3 and the bending section 32b that connects described the first segmental arc 32a and described the second segmental arc 32c.
