Abstract
The utility model discloses a full ternary impeller of efficient, it includes the impeller body, be equipped with the main blade of 6-12 equipartitions on the impeller body, the main blade is held to the three-dimensional curved surface of turning to N recursion by the path, and the characteristic is: the three-dimensional curved surface of the sub-blade is formed by a small-diameter end and a large-diameter end which are bent reversely in the rotating direction, one sub-blade is arranged between every two adjacent main blades, and the axial length Y of each sub-blade is smaller than the axial length X of each main blade. The utility model has compact and reasonable structure; the impeller efficiency is further improved due to the adoption of a full ternary structure with the main blades and the sub-blades; meanwhile, the impeller is made of aluminum alloy with low mass, the inertia of the rotor is small, the dynamic balance of the rotor at high speed is convenient to maintain, and the efficiency is improved.
Description
Technical field
The utility model relates to a kind of complete efficiently 3 d impeller, specifically after improving on the basis of common 3 d impeller, has more high efficiency a kind of impeller, belongs to the mechanical structure technical field.
Background technique
At present; The major technique that is used for the homemade single-stage high-speed centrifugal blower in the aeration in sewage treatment system comes from the technology of introducing advanced country's the eighties; The impeller that uses on this series products is common 3 d impeller; Except the primary blades that three-dimension curved surface constitutes, do not divide blade, impeller adiabatic efficiency is on the low side relatively, is difficult to satisfy current to energy-conservation increasingly high requirement.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, thereby a kind of complete efficiently 3 d impeller is provided, and is convenient to keep the dynamic balancing under the rotor high-speed, and has higher working efficiency.
The technological scheme that provides according to the utility model; A kind of complete efficiently 3 d impeller comprises impeller body; Said impeller body is provided with 6-12 primary blades that is uniformly distributed with, and said primary blades constitutes to the three-dimension curved surface of bigger diameter end to rotation direction N back-flexing by miner diameter end, and characteristic is: also comprise the branch blade; Be provided with a branch blade in the middle of said every two adjacent primary blades, divide the axial length of the axial length of blade less than primary blades.
As the further improvement of the utility model, blade was made up of to the three-dimension curved surface of bigger diameter end to the rotation direction back-flexing miner diameter end in said minute.
As the further improvement of the utility model, said impeller body comprises primary blades, divides blade to be processed by aluminum alloy material integral body.
The utility model compact structure, reasonable; Have primary blades and the full ternary structural that divides blade owing to adopt, impeller adiabatic efficiency is further enhanced; Simultaneously, impeller is processed by the little aluminum alloy of quality, and rotor inertia is little, is convenient to keep the dynamic balancing under the rotor high-speed, helps the raising of efficient equally.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is a K-K sectional view among Fig. 1.
Embodiment
Following the utility model will combine accompanying drawing to further describe:
Like Fig. 1, shown in Figure 2: the utility model comprises impeller body 1, primary blades 2, divides blade 3.Said impeller body 1 is provided with primary blades 2 that 6-12 is uniformly distributed with and divides blade 3, and said primary blades 2 is with to divide blade 3 structures identical, by miner diameter end to bigger diameter end to rotation direction N back-flexing and through the three-dimension curved surface formation of optimal design.
Be provided with a branch blade 3 in the middle of said every two adjacent primary blades 2, divide the axial length Y of blade 3 axial length X less than primary blades 2.
Y/X=0.5-0.95。
Said impeller body 1 comprises primary blades 2, divides blade 3 to be processed by aluminum alloy material integral body.
When the utility model when diagram arrow N makes high-speed rotation; Air gets into impeller cavity 4 along the arrow A direction; Air under the centrifugal action of the utility model, an edge N direction high-speed rotation, on one side flow to Way out B; And receiving certain diffusion action, pressure ability and kinetic energy are all improved accordingly.Because primary blades 2 and the acting in conjunction that divides blade 3; Make the utility model higher than the efficient of the common 3 d impeller that does not divide blade, impeller is processed by the little aluminum alloy material of quality simultaneously, and rotor inertia is little; Be convenient to keep the dynamic balancing under the rotor high-speed, more help the raising of efficient.
