Abstract
The invention discloses a kind of draught fan impeller, linked together by blade including wheel cap and wheel disc, described wheel cap and described wheel disc, described wheel disc offers some equally distributed openings for alleviating described wheel disc weight.Compared with prior art, the equally distributed opening that the present invention offers on wheel disc can effectively reduce the weight of wheel disc, thus reducing the power of motor, reach energy-conservation purpose, simultaneously, owing to the thickness of wheel disc does not change, under the premise that quantity and the size of opening are control effectively, its intensity is without being affected.
Description
Technical field
The invention belongs to the technical field of blower fan, be a kind of draught fan impeller concretely, especially a kind of draught fan impeller that blower fan can be made more energy-conservation.
Background technology
Blower fan, as a kind of turbomachine carrying air, is widely used in commercial production and the daily life fields such as aviation, coal, electric power, metallurgy, electronics, automobile, air-conditioning.Impeller is the most important parts of centrifugal fan, and its function is by static energy that changes mechanical energy is gas and kinetic energy.
Blower fan is run by motor driven impeller, the watt level of motor is the wheel speed by this Fans and the weight of impeller, it is understood that the flow of blower fan and pressure size are to be determined by the rotating speed of impeller, so the rotating speed of impeller is also certain under the premise that flow and blast are certain, we reduce the power of motor only by the gross mass reducing impeller, reach energy-conservation purpose！Also reduce blower fan manufacturing cost, improve the competitiveness of enterprise！The decline of impeller gross mass also reduces centrifugal force when impeller runs, and improves the safety that impeller runs！From cost, energy-conservation and secure context, it is all the most feasible for reducing impeller weight, at present, the most direct and simplest method is the purpose reaching to alleviate weight by thinning impeller thickness of slab, if application number is the Chinese utility model patent of 201020605807.5, discloses one 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 remainder.
But it is understood that the hazardness of blower fan accident, thinning impeller thickness of slab necessarily brings the consequence of the decrease in strength of original impeller, then be increased by the probability that accident occurs！So the purpose of weight can not be reached to alleviate simply by thinning impeller thickness of slab！
Summary of the invention
The present invention is directed to deficiency of the prior art, it is provided that a kind of make blower fan operating more energy-conservation and draught fan impeller without influence on impeller intensity.
In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals: a kind of draught fan impeller, including wheel cap and wheel disc, described wheel cap and described wheel disc are linked together by blade, it is characterised in that: described wheel disc offers some equally distributed openings for alleviating described wheel disc weight.The equally distributed opening that the present invention offers on wheel disc can effectively reduce the weight of wheel disc, thus reducing the power of motor, reaches energy-conservation purpose, simultaneously, owing to the thickness of wheel disc does not change, under the premise that quantity and the size of opening are control effectively, its intensity is without being affected.
As preferably, above-mentioned opening is be arranged on the hole in the middle part of described wheel disc.
As another preferred version, above-mentioned opening is the breach being arranged on described wheel disc edge.First the breach being arranged on wheel disc edge is processed more convenient, and without influence on the overall result of use of impeller, it is often more important that, at the conventional easy dust stratification of blade end, and the setting of breach of the present invention makes blade end not easily dust stratification.
In order to obtain superior technique effect, further technical measures also include: being respectively provided with a described breach between the described blade that each two is adjacent, described breach ecto-entad is gradually reduced, and its opening direction is consistent with impeller direction of rotation.The breach of the technical program and the flow direction of wind adapt, and are more beneficial for dust and pass through from indentation, there, make the better effects if of removal dust.
Further, the edge of above-mentioned breach is the arc in " hooks " shape, and this arc includes the first segmental arc of the end of close described blade, away from the second segmental arc of this blade and connect described first segmental arc and the bending section of described second segmental arc.Having technical effect that so that the effect removing the dust on blade optimizes further of this programme.
In order to while alleviating weight ensure impeller intensity be not subjected to impact, the area of all above-mentioned breach and less than or equal to 20 the percent of described wheel disc area.Due to wheel disc uniform thickness everywhere, therefore, the weight of the material of the indentation, there that wheel disc is removed is equivalent to former 20 the percent of disc thickness of taking turns, and generally the weight of wheel disc accounts for 50 the percent of whole impeller weight, therefore, the impeller of this programme is compared original impeller and is alleviated the weight of 10.
Compared with prior art, the method have the advantages that the equally distributed opening that the present invention offers on wheel disc can effectively reduce the weight of wheel disc, thus reducing the power of motor, reach energy-conservation purpose, simultaneously, owing to the thickness of wheel disc does not change, under the premise that quantity and the size of opening are control effectively, its intensity is without being affected.

Detailed description of the invention
Embodiment 1.
A kind of draught fan impeller, is linked together by blade 3 including wheel cap 1 and wheel disc 2, described wheel cap 1 and described wheel disc 2, described wheel disc 3 offers some equally distributed openings for alleviating described wheel disc 3 weight.
Above-mentioned opening is be arranged on the hole 31 in the middle part of described wheel disc 3, is provided with 1 hole 31 between the blade 3 that each two is adjacent, and the area in each hole 31 is all identical, and it is generally circular in shape in the present embodiment, and the position in hole 31 is premised on the position of centre of gravity not affecting wheel disc.
Embodiment 2.
A kind of draught fan impeller, is linked together by blade 3 including wheel cap 1 and wheel disc 2, described wheel cap 1 and described wheel disc 2, it is characterised in that: described wheel disc 3 offers some equally distributed openings for alleviating described wheel disc 3 weight.
Above-mentioned opening is the breach 32 being arranged on described wheel disc 3 edge, and is respectively provided with a described breach 32 between the adjacent described blade 3 of each two, and described breach 32 ecto-entad is gradually reduced, and its opening direction is consistent with impeller direction of rotation.Same, the shape of each breach 32, size are all identical, and its position is also premised on the position of centre of gravity not affecting wheel disc.
Specific to the present embodiment, the edge of above-mentioned breach 32 arc in " hook " shape, this arc includes the first segmental arc 32a of end near described blade 3, away from the second segmental arc 32c of this blade 3 and connect described first segmental arc 32a and the bending section 32b of described second segmental arc 32c.
The area of all described breach 32 and equal to described wheel disc 3 area 20 percent.Certainly, the area of all described breach 32 and less than 20 the percent of wheel disc 3 area, but energy-conservation effect can be also reduced simultaneously.
