Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of energy-efficient cross-section flow passage impeller, including shroud
11, hub disk 12, wheel hub 13, blade 14, shroud 11 and hub disk 12 are annular disc, and hub disk 12 is anchored on wheel hub 13, multiple
Blade 14 is arranged circumferentially along wheel hub 13, and is connect with shroud 11, hub disk 12, is formed between each adjacent two blade 14 transversal
Area is between the input end tangent line of 15 blade 14 of cross-section runner and the tangent to periphery of input end that airflow direction is equal
Angle is vane inlet angle beta 1, and the angle between the outlet end tangent line of blade 14 and the tangent to periphery of outlet end is outlet blade angle
β 2, since the shape and arrangement form of blade 14 are different, cross-section runner 15 can go out according to vane inlet angle beta 1 and blade
The angular range difference of bicker β 2 is arranged to forward-type cross-section runner, backward type cross-section runner, radial cross-section runner
Three kinds, to adapt to the requirement of different wind pressure and air quantity.
In the present embodiment, blade 14 is equipped with 8, is arranged circumferentially along wheel hub 13, and blade 14 is welded on shroud 11
On hub disk 12；Wheel hub 13 is cast by aluminium alloy or by steel-casting, and it is logical that 13 edge of wheel hub is circumferentially uniformly arranged multiple first
Hole 131,12 inward flange of hub disk is circumferentially uniformly arranged multiple second through-holes, and passes through above-mentioned 131 He of first through hole by bolt 16
Second through-hole is fixed by hub disk 12 and wheel hub 13, since bolt 16 blocks above-mentioned second through-hole, so do not have in FIG. 1 to FIG. 3
Have and the second through-hole is labeled；The axial axis hole 132 offered for installing shaft of above-mentioned wheel hub 13；Above-mentioned shroud 11 is along interior
Circumferential surface extends a tubular boss to far from 12 direction of hub disk.As shown in Fig. 2, above-mentioned blade 14 includes the first blade face 141
With the second blade face 142, the first blade face 141 and the second blade face 142 are round and smooth fillet surface, and the second leaf of each blade 14
Above-mentioned cross-section runner 15 is formed between face 142 and the first blade face 141 of adjacent blades 14.Since blade 14 is curved shape
Shape, the cross-sectional area of the cross-section runner 15 are each to edge by impeller center along airflow direction from the inside to the outside roughly the same
Locate to be less than 10mm with the range that differs of the sectional area of the vertical direction of air-flow tangent line.
Cross-section runner 15 as shown in Figure 4, vane inlet angle beta 1 be 40~60 °, blade exit angle beta 2 be 140~
160°.Since the curved shape and the direction of motion of air under the action of the centrifugal force of blade 14 are completely on the contrary, air and blade 14
Between hit acutely, therefore energy loss and noise are all larger, and efficiency is lower, but can make air with higher flow velocity from impeller
In throw away, so that air be made to obtain biggish pressure at fan outlet.
Cross-section runner 15 as shown in Figure 5, vane inlet angle beta 1 are 25~45 °, and blade exit angle beta 2 is 30~60 °,
The curvature that the blade 14 of the structure compares the blade 14 in Fig. 4 is smaller, and meets the movement side of air-flow under the action of the centrifugal force
To, very little is hit between air and blade, therefore energy loss is few, high-efficient, noise is small when operating, but can only make air with
Lower flow velocity is thrown away from impeller, and air is lower from pressure obtained in blower.
The export direction of cross-section runner 15 as shown in FIG. 6, blade 14 is radial along wheel hub 13, and blade exit angle beta 2 is
90 °, its main feature is that runner is unobstructed to be not easy dust accumulation, and intensity is higher.
Above-mentioned three kinds of blade arrangement forms are adapted to the requirement of different wind pressure and flow, can when needing to improve air quantity
Select arrangement form shown in Fig. 4；When needing flow larger, arrangement form shown in fig. 5 can be selected.
The blade 14 of the utility model can be solid vane, directly be integrally formed with impeller, simple process, guarantee impeller
Balance；The blade 14 of the utility model can also be to be hollow, and with excellent air pertormance, 14 intensity of blade is high, from
The pneumatic efficiency of heart blower is higher.
The energy-efficient cross-section flow passage impeller of the utility model is due to uniform flow passage arrangement and cross-sectional area substantially phase
Together, may be implemented air velocity uniformly, without vortex, resistance is small, with small vibration, low energy consumption, running noise is low, and can be by centrifugal blower
Operational efficiency improves 8~10%, and energy consumption reduces by 6~8%, and wind pressure improves 8%~10%.
Specific embodiment of the present utility model described above does not constitute the restriction to scope of protection of the utility model.
Any other various changes and modifications that any technical concept according to the present utility model is made should be included in practical
In novel scope of protection of the claims.
