Abstract
The utility model discloses a kind of quasi- zero clearance axial flow blowers, including impeller, air duct and motor, the impeller includes a wheel hub being connected on motor output shaft and several blades for being evenly distributed on hub periphery face, the wing tip of the blade is equipped with a circle wing tip partition board, current collector there are one being set on the air duct air inlet flange, one end of wing tip partition board towards the current collector is stretched between current collector and air duct inner wall.As a result of the combination of wing tip partition board and current collector so that form a kind of cold zero clearance between impeller blade tip and air duct inner wall, play noise reduction, pressure-raising reduces flow losses, improves equipment dependability and extends the function of equipment operation life cycle.Equipment operating pressure is improved, blade vibration is reduced, extends impeller service life, solves surge problems, widens equipment operation workspace.
Description
Technical field
The utility model is related to a kind of axial flow blower model, impeller and air duct in a kind of axial flow blower are particularly related to
Between quasi- zero clearance model.
Background technology
Axial flow blower is made of impeller, motor and air duct three-major-items, and impeller is as a rotary part, the inner wall with air duct
Between there is certain gap, this gap is bigger, and the efficiency of wind turbine is lower, noise is bigger, and airflow pressure is also lower, when height turns
When fast, the blade on impeller has a certain amount of deformation, and the overall performance for even more exacerbating wind turbine is deteriorated.With China's economy and
The fast development of industry, urgent need want a kind of axial flow blower with high-efficient low-noise to be applied to various ventilations, fire-fighting occasion.
Utility model content
To overcome drawbacks described above, the utility model be intended to provide it is a kind of it is efficient, noise is low, performance is stablized, and is suitble to various
The quasi- zero clearance axial flow blower of environmental condition.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of quasi- zero clearance axial flow blower, including leaf
Wheel, air duct and motor, the impeller include a wheel hub being connected on motor output shaft and are evenly distributed on hub periphery face
On several blades, the wing tip of the blade is equipped with a circle wing tip partition board, sets that there are one collection on the air duct air inlet flange
Device is flowed, one end of wing tip partition board towards the current collector is stretched between current collector and air duct inner wall.
Set that there are one import partition boards on the air duct air inlet flange to replace current collector, the wing tip partition board is towards air inlet
One end of mouth is equal with the inner end of import partition board, and the gap of the wing tip partition board and import partition board is 2-5 millimeters.
The axial flow blower for using the technical program, as a result of the combination of wing tip partition board and current collector so that impeller
A kind of cold zero clearance is formed between blade tip and air duct inner wall, plays noise reduction, and pressure-raising reduces flow losses, improves equipment dependability
With the function of extending equipment operation life cycle.Equipment operating pressure is improved, blade vibration is reduced, extends impeller service life,
Surge problems are solved, equipment operation workspace is widened.
Description of the drawings
Fig. 1 is one structural schematic diagram of the embodiments of the present invention；
Fig. 2 is two structural schematic diagram of the embodiments of the present invention.
In figure：1- impellers, 2- air ducts, 3- motors, 4- wheel hubs, 5- blades, 6- wing tip partition boards, 7- current collectors, 8- imports every
Plate.
Specific implementation mode
Embodiment one：As shown in Figure 1, the utility model discloses a kind of quasi- zero clearance axial flow blower, including impeller 1, wind
Cylinder 2 and motor 3, the impeller 1 include a wheel hub 4 being connected on 3 output shaft of motor and are evenly distributed on 4 peripheral surface of wheel hub
On several blades 5, in conclusion almost the same with the structure of existing common axial flow blower, innovative point essentially consists in
The wing tip of the blade 5 is equipped with a circle wing tip partition board 6, and the wing tip partition board 6 is cylindrical shape, the width phase of thickness and blade 5
Matching, i.e., blade 5 is roughly the same in the projection width of 1 axis direction of impeller, also, the cylinder outer wall and air duct of wing tip partition board 6
Inner wall 2 it is parallel, gap is usually at 5-10 millimeters；Current collector 7 there are one being set on 2 air inlet flange of the air duct, afflux
Device 7 is bell mouth shape, microcephaly towards wing tip partition board 6, one end of wing tip partition board 6 towards the current collector 7 stretch into current collector 7 with
About 2-5 millimeters between 2 inner wall of air duct.In this way, when impeller 1 rotates, current collector 7 plays the role of a trapping so that leaf
A kind of state of quasi- zero clearance is formed between wheel 1 and air duct 2.
Embodiment two：As shown in Fig. 2, being set on 2 air inlet flange of the air duct, there are one import partition boards 8 to replace current collector
7, the import partition board 8 is fixed on 2 flange of air duct, and to the extension at 2 center of air duct, and the wing tip partition board 6 is towards air inlet
One end it is equal with the inner end of import partition board 8, the gap of the wing tip partition board 6 and import partition board 8 is 2-5 millimeters.Due to import
The making of partition board 8 with it is easier for installation, cost is also lower, at the same can play with effect similar in current collector 7, so in reality
Production occasion is more widely used.
