Abstract
Provided is an adjustable impeller structure of an axial-flow air blower. The structure includes an adjustable impeller, the plurality of blades on the adjustable impeller are adjustable, and are in an integral structure with a blade rotating shaft, the blade rotating shaft is arranged between the impeller wheel hub A and the impeller wheel hub B which are in a cohesive structure, the impeller wheel hub A and the impeller wheel hub B are fastened by a fastening bolt & nut assembly, thereby the blades are fastened, the elevation angle of the blades is adjusted by the blade rotating shaft, the impeller wheel hub A, the impeller wheel hub B and the fastening bolt & nut assembly. By adopting the adjustable impeller structure of the axial-flow air blower, the angle of the blades can be adjusted while the air blower is out of work, and the optimum operating point of the air blower is optimized by adjusting the angle of the blades. The adjustable impeller structure of the axial-flow air blower in the utility model has the characteristics of simple structure, convenient manufacture and installation, low cost and good application effect.
Description
Technical field
The utility model relates to a kind of adjustable impeller structure of axial-flow blower, belongs to the industrial fan product technical field.
Background technique
A large amount of at present at the AXA/B of industrial use profile shaft flow fan, mainly be by: draught fan impeller, Blower Housing, motor are constituted, the axial-flow blower of this structure type, blade structure on its draught fan impeller is the stationary structure blade, the elevation angle of blade, the angle that is blade can not be regulated, and gently approach, in use be easy to distortion, thereby influence the aerodynamic performance of blower fan, the best operating point of blower fan just can not be optimised like this, influences the usability and the working efficiency of blower fan, and the noise of blower fan is also bigger.
Summary of the invention
The utility model provides a kind of adjustable impeller structure of a kind of axial-flow blower of novelty, but adopts blade elevation angle conditioning technology, to realize good low noise performance of axial-flow blower and the purpose that improves aerodynamic performance.
The technical solution adopted in the utility model is:
A kind of adjustable impeller structure of axial-flow blower, comprise: adjustable impeller, some blades on the described adjustable impeller are the adjustable structure blade, blade and blade rotor are monolithic construction, blade rotor is installed on impeller to be changeed between hub A, the impeller commentaries on classics hub B, impeller changes hub A, impeller commentaries on classics hub B, and the two is obvolvent shape structure, and the fastening impeller of clamping bolt nut assembly changes hub A, impeller changes hub B, thus fastening blade rotor.
The elevation angle of blade is regulated by blade rotor, impeller commentaries on classics hub A, impeller commentaries on classics hub B, clamping bolt nut assembly.
The utility model beneficial effect is:
Owing to adopted the adjustable impeller structure of a kind of axial-flow blower of the present utility model; adjustable blade angle when blower fan is shut down; by adjusting blade angle; optimize the best operating point of blower fan; the adjustable impeller structure of a kind of axial-flow blower of the present utility model has: simple in structure; make easy for installationly, cost is low, the characteristics that using effect is good.

Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.
Blower fan, mainly by: adjustable impeller 1, Blower Housing 2, motor 3 are constituted.
Adjustable impeller 1 comprises: blade 31, blade rotor 32, impeller change hub A33, impeller changes hub B34, clamping bolt nut assembly 35 structures.
A kind of adjustable impeller structure of axial-flow blower, comprise: adjustable impeller 1, some blades 31 on the described adjustable impeller 1 are the adjustable structure blade, blade 31 is a monolithic construction with blade rotor 32, blade rotor 32 is installed on impeller to be changeed between hub A33, the impeller commentaries on classics hub B34, impeller changes hub A33, impeller commentaries on classics hub B34, and the two is obvolvent shape structure, and clamping bolt nut assembly 35 fastening impellers change hub A33, impeller changes hub B34, thus fastening blade rotor 32.
The elevation angle of blade 31 is regulated by blade rotor 32, impeller commentaries on classics hub A33, impeller commentaries on classics hub B34, clamping bolt nut assembly 35.
Basic functional principle: when blower fan starts use, because the stator blade of axial-flow blower wing blades is adjustable, make wing blades guarantee the efficient and low noise of blower fan, simultaneously by adjusting blade angle, optimize the best operating point of blower fan, the purpose that realizes reducing fan noise and improve aerodynamic performance.
