Description
Technical field
It the utility model is related to blower technology field, and in particular to a kind of special double absorbing impellers of centrifugal blower.
Background technology
Centrifugal blower is a kind of rotating vanes gas compression machinery, and gas is sucked by induction chamber, by impeller to gas
Body does work, and improves gas pressure, speed, temperature, so kinetic energy is changed into pressure energy, enters pressure by the right side by diffuser element
One step improves, and impeller is air blower core part, is sole component of the air blower to gas work done.For common impeller,
The impeller that gas is rotated is sucked by entering mouth circle, and gas flows vertically produces axial force, this partial action to impeller
Power need by the balancing frame and bearing in fan rotor portion come reaction offset, therefore for using common impeller air blower and
Speech, bearing is more fragile, greatly reduces the service life of air blower.Flow is bigger simultaneously, and the exit width of impeller is bigger, leaf
It is bigger to take turns stress, it is higher to impeller choice requirement.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and provides a kind of structurally simple, economical conjunction
Reason, the special double absorbing impellers of centrifugal blower that impeller life can be improved, reduce impeller choice requirement.
To achieve the above object, the technical solution of the utility model is：A kind of special double absorbing impellers of centrifugal blower, it is main
To include mid-game, revolver lid, right wheel lid, mouth circle is entered on a left side, mouth circle is entered on the right side, lobus sinister piece, lobus dexter piece, wheel hub, pressure ring, the mid-game
Disk body front is welded with lobus sinister piece, and the disk body reverse side of the mid-game is welded with lobus dexter piece, the lobus sinister piece and lobus dexter piece along mid-game
Radial symmetric is set, and the revolver lid and the integral right side of left import lap welding are welded on lobus sinister piece again, and the right wheel lid and the right side are entered
Mouth circle be welded into one it is right be welded on again on lobus dexter piece, the left side enters mouth circle and enters the setting of mouth circle mid-game radial symmetric with the right side, in described
Disk, revolver lid, right wheel lid, mouth circle is entered on a left side, mouth circle is entered on the right side, lobus sinister piece, lobus dexter piece are welded as a whole structure, the mid-game, wheel hub,
And articulation hole is provided with pressure ring, the integrative-structure passes through the hinged bolts, the cover type nut that are arranged on articulation hole
It is connected with wheel hub and pressure ring.
The utility model is using the beneficial effect of above-mentioned technical proposal：The utility model passes through lobus sinister wheel portion and lobus dexter wheel
Portion shares a mid-game, the blade on mid-game two sides, wheel disc, enters the full symmetric arrangement of mouth circle.Impeller is rotated at a high speed by main shaft, main
Axle is fixed in fan stator portion by the bearing at both ends, and when high speed rotates, gas axle caused by mouth circle is entered in impeller both sides
It is equal in magnitude to directed force F 1, F2, in the opposite direction, cancel out each other, substantially prolongs the service life length of impeller.The utility model
The single side outlet width of impeller is the half of single absorbing impeller, and blade wheel structure is reasonable, and stressing conditions are good, and unfailing performance is good, and drops
The low material requirements of impeller, reduces cost.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model partial structural diagram.
Embodiment
The utility model is further described with reference to the accompanying drawings and examples, but not formed to of the present utility model
Any restrictions.
As shown in Figure 1 and Figure 2, the special double absorbing impellers of a kind of centrifugal blower, mid-game 1, revolver lid 2, right wheel are mainly included
Lid 3, a left side enter mouth circle 4, mouth circle 5 is entered on the right side, lobus sinister piece 6, lobus dexter piece 7, wheel hub 8, pressure ring 9, and the disk body front of the mid-game 1 is welded with
Lobus sinister piece 6, the disk body reverse side of the mid-game 1 are welded with lobus dexter piece 7, the lobus sinister piece 6 and lobus dexter piece 7 along the radial symmetric of mid-game 1
Set, the revolver lid 2 and a left side are entered after mouth circle 4 is welded into one to be welded on again on lobus sinister piece 6, and mouth circle 5 is entered on the right wheel lid 3 and the right side
It is welded on again on lobus dexter piece 7 after being welded into one, the left side enters mouth circle 4 and enters mouth circle 5 with respect to the setting of the radial symmetric of mid-game 1, institute with the right side
State mid-game 1, revolver lid 2, right wheel lid 3, mouth circle 4 is entered on a left side, mouth circle 5 is entered on the right side, lobus sinister piece 6, lobus dexter piece 7 are welded as a whole structure, institute
