Abstract
The utility model discloses a kind of wind motor leafs with stacking sealing structure, are installed in axial flow blower, petiole slot is offered on the wheel hub of the axial flow blower；The wind motor leaf includes movable vane handle and movable vane piece, and the movable vane piece connects with the top of the movable vane handle；Movable vane handle lower part offers the first groove around movable vane handle periphery, and upper part offers the second groove around movable vane handle periphery, is provided with the first sealing ring in first groove, is provided with the second sealing ring in second groove；First sealing ring and the second sealing ring are located in the petiole slot.This structure uses the sealing ring of dual structure, so that movable vane handle reduces gap when installing, plays sealing function, prevents sundries, water or air-flow from entering, and effectively prevent foreign matter card plug or corrosion card plug, improves the reliability of blower.
Description
Technical field
The utility model relates to blower technical field more particularly to a kind of wind motor leafs with stacking sealing structure.
Background technique
In unit operation, according to operating condition needs, relative motion will occur axial flow blower for movable vane and wheel hub, that is, take turns
When hub high speed rotation, movable vane will be along axial selection, to control axial flow blower power output.Therefore between the petiole of wind motor leaf and petiole slot
Existing installation gap is easy to allow sundries or water to enter, and causes gap to block or corrode stuck, causes wind motor leaf rotation not
, blower power output is out of control, or causes the balance of movable vane, and equipment damage seriously affects fan operation safety and equipment
Reliability.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of wind with stacking sealing structure
Motor-driven leaf.
The utility model is achieved through the following technical solutions: a kind of wind motor leaf with stacking sealing structure,
It is installed in axial flow blower, petiole slot is offered on the wheel hub of the axial flow blower；The wind motor leaf includes movable vane handle and moves
Blade, the movable vane piece connect with the top of the movable vane handle；Movable vane handle lower part is offered around movable vane handle periphery
The first groove, upper part offers the second groove around movable vane handle periphery, is provided with first in first groove
Sealing ring is provided with the second sealing ring in second groove；First sealing ring and the second sealing ring are located at the petiole
In slot.
The setting of double sealing ring, can avoid sundries and water enters in petiole slot, effectively prevent foreign matter card plug or corrosion card
Plug, improves the reliability of blower.
Second sealing ring uses viton seal ring.Viton seal ring has high temperature resistant, oil resistant, resistance to high vacuum
And the performance of acid and alkali-resistance.
The distance between deckle of second sealing ring and the movable vane handle is 2cm.
The width of second sealing ring is 1cm.
The cross-sectional profile of second sealing ring is circle.
The cross-sectional profile of second sealing ring is ellipse.
It is compared with the prior art, utility model has the advantages that this structure uses the sealing ring of dual structure, so that dynamic
Petiole reduces gap when installing, and plays sealing function, prevents sundries, water or air-flow from entering, and increases intake air flow and vacuum
Degree enhances movable vane wheel air draught effect, improves complete machine working efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Appended drawing reference meaning in figure: 1, petiole slot；2, movable vane handle；3, movable vane piece；4, the first sealing ring；5, the second sealing
Circle.
Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
Embodiment
Refering to fig. 1, it is a kind of wind motor leaf with stacking sealing structure, is installed in axial flow blower, axial flow blower
Petiole slot 1 is offered on wheel hub；Wind motor leaf includes movable vane handle 2 and movable vane piece 3, and movable vane piece 3 connects with the top of movable vane handle 2；
2 lower part of movable vane handle offers the first groove around 2 periphery of movable vane handle, and upper part offers second around 2 periphery of movable vane handle
Groove is provided with the first sealing ring 4 in the first groove, the second sealing ring 5 is provided in the second groove；First sealing ring 4 and
Two sealing rings 5 are located in petiole slot 1.
The setting of double sealing ring, can avoid sundries and water enters in petiole slot 1, effectively prevent foreign matter card plug or corrosion card
Plug, improves the reliability of blower.
Second sealing ring 5 uses viton seal ring.Viton seal ring has high temperature resistant, oil resistant, resistance to high vacuum and resistance to
The performance of soda acid.
The distance between second sealing ring 5 and the deckle of movable vane handle 2 are 2cm.
The width of second sealing ring 5 is 1cm.
The cross-sectional profile of second sealing ring 5 is circle.
The cross-sectional profile of second sealing ring 5 is ellipse.
Above-listed detailed description is illustrating for the utility model possible embodiments, and the embodiment is not to limit
The scope of the patents of the utility model, all equivalence enforcements or change without departing from carried out by the utility model, is intended to be limited solely by this case
In the scope of the patents.
