Abstract
A propeller-type axial-flow impeller is installed on a driving bearing and is formed by fixedly connecting a plurality of vanes, wheel hubs and flanges through fasteners, wherein the vanes and the wheel hubs of the impeller are twisted like a three-dimensional curved surface; the number of the vanes ranges from four to eight; the diameter of the impeller ranges from 315 mm to 1800 mm; the width of each vane ranges from 91 mm to 432 mm; and the diameter of each wheel hub ranges from 48 mm to 300 mm. The axial-flow impeller has the following advantages: the propeller-type axial-flow impeller of the utility model ensures that air flow becoms more stable and the generation of turbulent flow caused by the collision of air currents is avoided, and noises during operating are effectively reduced; and the noise is reduced by 10% compared with similar products; the dynamic balance grades of the impellers of various models reach the G 4.0 standard, and the dynamic balance grades can reach G 2.5 when the impellers are small, so as to effectively prolong the service life of a blower provided with the propeller-type axial-flow impeller; the ranges of inflow air and outflow air cover the whole circumferential surface when the propeller-type axial-flow impeller operates, so that the amount of the outflow air is balanced; and compared with a common impeller, the efficiency is improved by 5% when the propeller-type axial-flow impeller of the utility model operates.
Description
Technical field
The utility model relates to a kind of axial-flow blower, especially a kind of propeller-type axial-flow blower.Different materials is widely used in multiplely sending, air bells exhauster according to selecting for use for this impeller, and the kind of drive can be carried out direct transmission or belt transmission by electrode.Can be used for getting rid of harmful gas, industrial high temperature waste gas and corrosive gass such as high temperature or fire-fighting smoke evacuation, also can be used for the occasion of the air-cooled cooling of air-conditioning unit heat extraction, pipe ventilated and all kinds of local ventilation or displacement ventilation system simultaneously.
Background technique
In the prior art, axial flow fan vane wheel applies to be installed in the blower fan on pipeline, roof, the abutment wall morely, is mainly used in from indoor eliminating gas, or to the indoor pure and fresh air of sending into, and finishes the sending of designing institute regulation, air draft requirement.
Homemade impeller adopts the steel welding form, and the impeller quality is heavier.Because the restriction that domestic common axial-flow blower is subjected to bind mode causes selection single, the many impellers in back are installed the shortcoming that can not change.Blade on the common axial-flow blower and wheel hub by changing blade angle, make this impeller reach different airflow pressures when being connected, and the scope of on-stream turnover wind concentrates on the blade scope morely, and wheel hub and intermediate bearing air quantity are less.In addition, noise is bigger in the running for common axial-flow blower.And the dynamic balancing grade of impeller makes impeller reduce coaxality and axle center degree in the process of running usually at G6.3, has caused centrifugal force and off-centre, causes fatigue damage easily, finally causes descend the working life of bearing.The more important thing is that its efficient of the axial flow fan vane wheel of prior art is lower, generally be no more than 40%.
Summary of the invention
Technical problem to be solved in the utility model adopts and to provide that a kind of raising is sent, air bells exhauster efficient, and running noise is little, the propeller-type axial-flow blower that the life-span is long.
The utility model solves the problems of the technologies described above the technological scheme of being taked: a kind of propeller-type axial-flow blower, be installed on the driving bearing, be formed by fixedly connecting by fastening piece by most blades, wheel hub, flanges, wherein, the most individual blade and the wheel hub of described impeller are the distortion of three-dimension curved surface type, and blade is four to eight, and impeller diameter is 315～1800mm, width of blade is 91～432mm, and hub diameter is 48～300mm.
The blade of the utility model propeller-type axial-flow blower and wheel hub be with the numerical control device cuts sheet material, and use the precision die impact briquetting.
On the basis of such scheme, the blade of described impeller is four, and blade is 6.5～6.8: 1 with the diameter ratio of wheel hub.
On the basis of such scheme, described impeller diameter is 3.3～3.5: 1 with the ratio of width of blade.
On the basis of such scheme, the blade of described impeller is six, and blade is 6～6.2: 1 with the diameter ratio of wheel hub.
On the basis of such scheme, described impeller diameter is 4～4.2: 1 with the ratio of width of blade.
On the basis of such scheme, described wheel hub is crossed rivet with blade pass and is fixedlyed connected, and wheel hub is fixedlyed connected by screw with flange.
On the basis of such scheme, described impeller and driving bearing are detachable fixing, and the flange of impeller is connected with bearing fixing by screw.The propeller-type aial flow impeller of different size model be dismantled and be changed to propeller-type axial-flow blower of the present utility model can easily according to different needs after installation.
The invention has the beneficial effects as follows:
1, propeller-type axial-flow blower of the present utility model makes air flow more stable in the running, avoids airflow collision to produce current stabilization, and can effectively reduce noise, has reduced by 10% than the noise of like product;
2, the dynamic balancing grade of the impeller of various models reaches the standard of G4.0, and balance level can reach G2.5 under the less situation of impeller size, and the fan life that this propeller-type axial-flow blower is installed is effectively improved;
3, the propeller-type axial-flow blower is in the process of running, and the turnover demeanour is enclosed and covered the whole circumference face, makes air output comparatively balanced;
Its efficient increases by 5% than general axle impeller when 4, turning round in the propeller-type axial-flow blower of the present utility model.
