Abstract
The utility model designs a wear-resistant impeller of a double-suction centrifugal fan, which comprises a front disc, vanes, a middle disc, a shaft disc, a middle disc protecting layer, a vane protecting layer, a dust-proof striking plate, bolts and nuts. The wear-resistant impeller is characterized in that the vanes rotate along the impeller in an airfoil-shaped direction, the front disc is an arc-shaped surface, the middle disc is a strengthened-type flat plate, striking surfaces of the vanes are welded with a protecting layer, connecting positions of the middle disc and the vanes are welded with a hook-shaped protecting layer, and the dust-proof striking plate welded on front edges of the vanes projects from the protecting layer of the vanes. The utility model has the advantages of resisting impacts and abrasion of air containing dusts and having a prolonged service life compared with same type vanes.
Description
Technical field
The utility model relates to a kind of centrifugal blower fan blade wheel, particularly a kind of wear-resisting double-suction centrifugal pump draught fan impeller.
Background technique
At present, when manufacturing and designing wear-resisting double-suction centrifugal pump draught fan impeller, adopt material selection, structural design and build-up wear-resistant material, though the working life of impeller prolongation is arranged, but still be difficult to satisfy under the operating mode rugged environment needs to impeller abrasion-proof.
Summary of the invention
The purpose of this utility model is under the dust working condition, to the not enough problem of impeller abrasion-proof, to provide a kind of wear-resisting double-suction centrifugal pump draught fan impeller in solving prior art.
The utility model designs a kind of wear-resisting double-suction centrifugal pump draught fan impeller; comprise left and right sides shroud, left and right sides blade, mid-game, reel, middle disc protective layer, blade protection layer, dustproof striking plate and bolt and nut; it is characterized in that: blade is a wing blade along the direction of wheel rotation; shroud is an arc shaped surface; mid-game is reinforced flat board, and the blade face of being hit is welded with protective layer, and mid-game and blade joint are welded with hook-shaped protective layer; the blade forward position is welded with dustproof striking plate, and gives prominence to outside protective layer.
The utility model has the advantages that the impact wear of anti-dust-containing airflow, the life-span rises appreciably than similar blade.
Description of drawings
Accompanying drawing 1 is a side structure schematic representation of the present utility model.
Accompanying drawing 2 is a Facad structure schematic representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Comprise shroud 1, blade 2, mid-game 3, bolt and nut 4, reel 5, middle disc protective layer 6, dustproof striking plate 7 and blade protection layer 8 among the figure; it is characterized in that: the face of being hit of blade 2 is welded with blade protection layer 8; blade 2 is welded with hook shape protective layer 6 with the mid-game joint, and the front portion of blade 2 is welded with dustproof striking plate.
In use,, reach wear-resisting effect, prolonged impeller working life because blade 2 positions easy to wear all are protected.
Claims (2)
1, a kind of wear-resisting double-suction centrifugal pump draught fan impeller; comprise shroud, blade, mid-game, reel, middle disc protective layer, blade protection layer, dustproof striking plate and bolt and nut; it is characterized in that: blade is a wing blade along the direction of wheel rotation; shroud is an arc shaped surface; mid-game is reinforced flat board; blade is welded with protective layer, and mid-game and blade joint are welded with hook-shaped protective layer, and the blade forward position is welded with dustproof striking plate.
