Abstract
The utility model discloses an efficient fully-three-dimensional impeller, which comprises an impeller body. Main blades are evenly distributed on the impeller body and the number of the main blades is from six to twelve. The main blades are all formed by three-dimensional curved surfaces which are recurved towards the direction of turning N from a small diameter end to a large diameter end. The efficient fully-three-dimensional impeller is characterized by further comprising secondary blades. The secondary blades are formed by three-dimensional curved surfaces which are recurved towards the direction of turning from the small diameter end to the large diameter end. One secondary blade is respectively disposed in the middle of every two adjacent main blades, and the axial length Y of each secondary blade is smaller than the axial length X of each main blade. The efficient fully-three-dimensional impeller is compact and reasonable in structure and enables efficiency of the impeller to be further improved due to the adoption of the fully-three-dimensional structure of the main blades and the secondary blades. Meanwhile, the impeller is made of aluminum alloy with small mass, and rotor inertia is small, thereby facilitating maintenance of dynamic balance of a rotor at high speed and also facilitating improvement of efficiency.
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.
