Description
Technical field
The utility model is related to blower fan technical field, and specifically a kind of axial flow blower is with split type double-suction centrifugal pump leaf
Wheel.
Background technology
In existing ventilating system, the impeller in axial flow blower is typically by wheel cap, blade, wheel disc, wheel cap and reel
Composition, this impeller is more due to the number of blade, when blade and wheel disc are welded in order to prevent welding deformation disconnected using one side
Weld, its deficiency is：Not prison welding is solid, it is short to weld yielding, service life.
The content of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, there is provided a kind of structure is novel, make simple, weldering
Connect convenience, axial flow blower double-suction type centrifugal impeller that is firm, being difficult output welding deformation long service life.
The utility model solves the technical scheme that its technical problem used：
A kind of axial flow blower split type double-suction centrifugal pump impeller, including revolver lid, right wheel lid, reel, wheel disc and blade, institute
State reel one end to be fixedly connected with revolver lid, the other end is fixedly connected with right wheel lid, it is characterised in that the reel outer wall is provided with
Positioning shaft shoulder, the wheel disc includes left wheel disk and right wheel disk, and the positioning shaft shoulder left end offsets with the left wheel disk being enclosed within reel
Touch, right-hand member is inconsistent with the right wheel disk being enclosed within reel, the left wheel disk, positioning shaft shoulder and right wheel disk are fixed through fastener and connected
Connect, the blade between the revolver lid and right wheel lid is each passed through left wheel disk and right wheel disk, make revolver lid, left wheel disk, right wheel disk and
Right wheel lid is fixedly connected respectively at blade, substantially increases the firmness of centrifugal impeller.
The utility model is not likely to produce weldering due to using said structure with simple structure, convenient welding, firm, impeller
The advantages of connecing deformation, increase the service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
The left view of Fig. 2 figure 1 above.
Reference：1. revolver lid, 2. left wheel disk, 3. right wheel disk, 4. right wheel lid, 5. blade, 6. positioning shaft shoulder, 7. axle
Disk.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of axial flow blower split type double-suction centrifugal pump impeller, including revolver lid 1, right wheel lid 4, reel 7, wheel disc and blade
5, the one end of the reel 7 is fixedly connected with revolver lid 1, and the other end is fixedly connected with right wheel lid 2, it is characterised in that the reel 7
Outer wall is provided with positioning shaft shoulder 6, and the wheel disc includes left wheel disk 2 and right wheel disk 3, the left end of the positioning shaft shoulder 6 be enclosed within reel 7
Left wheel disk 2 it is inconsistent, right-hand member is inconsistent with the right wheel disk 3 being enclosed within reel 7, the left wheel disk 2, positioning shaft shoulder 6 and right wheel
Disk 3 is fixedly connected through fastener, and the blade 5 between the revolver lid 1 and right wheel lid 2 is each passed through left wheel disk 2 and right wheel disk 3, makes
Revolver lid 1, left wheel disk 2, right wheel disk 3 are fixedly connected with right wheel lid 4 respectively at blade 5, substantially increase the firm of centrifugal impeller
Degree.
The utility model make when, after blade 5 is each passed through revolver lid 1, left wheel disk 2, right wheel disk 3 and right wheel lid 4, then
Welded with blade 5 respectively in the outside of revolver lid 1, left wheel disk 2, right wheel disk 3 and right wheel lid 4 respectively, two impellers are passed through into axle
Be riveted together for they by disk 7, forms a double-suction centrifugal pump impeller.
The utility model is not likely to produce weldering due to using said structure with simple structure, convenient welding, firm, impeller
The advantages of connecing deformation, increase the service life.
