Description
Technical field
The present invention relates to a kind of draught fan impeller, especially a kind of axial flow, centrifugal combined-type enclosed vortex fan impeller.
Background technique
At present, draught fan impeller is generally divided into axial flow and centrifugal.Axial fan does not have suction or suction very little.Centrifugal fan can only utilize 40% ~ 50% of drive motor power, and power of motor utilization ratio is little, and centrifugal fan runs noise greatly, and shake is severe.And the core component of blower fan is exactly impeller, the structure influence of impeller the performance of blower fan.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of noise little, operate steadily, power consumption is little, the high axial flow large with suction of efficiency, centrifugal combined-type enclosed vortex fan impeller.
According to technological scheme provided by the invention, described axial flow, centrifugal combined-type enclosed vortex fan impeller, comprise land, impeller, blade, spiral case, air guide sleeve and wind collecting unit, spiral case is fixed with at the upper-end surface cylindrical of land, be fixed with wind collecting unit in the upper end portion of spiral case, the cylindrical of impeller is fixed with blade, be fixed with air guide sleeve in the upper end portion of impeller, the upper semisection of described blade is axial--flow blading, and the lower semisection of blade is centrifugal blades.
The cylindrical of blade is provided with blade shroud.
Mechanical seal is provided with between air guide sleeve and blade shroud.
The present invention have noise little, operate steadily, power consumption is little, efficiency is high with the advantage such as suction is large, and structure of the present invention is simple, easily manufactured.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
This axial flow, centrifugal combined-type enclosed vortex fan impeller, comprise land 1, impeller 2, blade 3, spiral case 4, air guide sleeve 5 and wind collecting unit 6, impeller 2 is processed with the axis hole for being connected with motor output shaft and keyway, spiral case 4 is fixed with at the upper-end surface cylindrical of land 1, wind collecting unit 6 is fixed with in the upper end portion of spiral case 4, the cylindrical of impeller 2 is fixed with blade 3, air guide sleeve 5 is fixed with in the upper end portion of impeller 2, the upper semisection of described blade 3 is axial--flow blading, and the lower semisection of blade 3 is centrifugal blades.
The cylindrical of blade 3 is provided with blade shroud 7.
Mechanical seal 8 is provided with between air guide sleeve 5 and blade shroud 7.
Axial flow of the present invention, centrifugal combined-type enclosed vortex fan impeller, it had both had that the structure of axial flow type fan impeller is simple, solid and reliable, noise is little of the advantage such as function range of choice is wide, and the power consumption again with centrifugal fan impeller is little, efficiency is high with the advantage such as suction is large.
