Abstract
The invention relates to a wear-resisting centrifugal fan impeller comprising a front disk, a vane, a rear disk, a reel, a rear disk protecting layer, a vane protecting layer, a dustproof impingement plate and rivets. The wear-resisting centrifugal fan impeller is characterized in that the vane is in airfoil type along the impeller rotating direction, the front disk is an arc-shaped surface, and the rear disk is an enhanced surface plate; the vane is welded with a protecting layer, the joint of the rear disk and the vane is welded with a hook-shaped protecting layer, and the front edge of the vane is welded with the dustproof impingement plate and extrudes out of the protecting layer. The invention has the advantage of resisting impact wear of dusty gas, and the service life is obviously improved compared with the similar vane.
Description
Technical field
The present invention relates to a kind of centrifugal blower fan blade wheel, particularly a kind of wear-resisting centrifugal fan impeller.
Background technique
At present, when manufacturing and designing wear-resisting centrifugal 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
Purpose of the present invention is under the dust working condition, to the not enough problem of impeller abrasion-proof, to provide a kind of wear-resisting centrifugal fan impeller in solving prior art.
The present invention designs a kind of wear-resisting centrifugal fan impeller; comprise shroud, blade, hub disk, reel, back disc protective layer, blade protection layer, dustproof striking plate and rivet; it is characterized in that: blade is a wing blade along the direction of wheel rotation, and shroud is an arc shaped surface, and hub disk is reinforced flat board.The blade face of being hit is welded with protective layer, and hub disk and blade joint are welded with hook-shaped protective layer, and the blade forward position is welded with dustproof striking plate, and gives prominence to outside protective layer.
Advantage of the present invention is the impact wear of anti-dust-containing airflow, and the life-span rises appreciably than similar blade.
Description of drawings
Accompanying drawing 1 is a side structure schematic representation of the present invention.
Accompanying drawing 2 is a Facad structure schematic representation of the present invention.
Below in conjunction with drawings and Examples the present invention is elaborated.
Embodiment
Comprise shroud 1, blade 2, hub disk 3, rivet 4, reel 5, back disc protective layer 6, dustproof striking plate 7 and blade protection layer 8 among the figure.It is characterized in that: blade 2 faces of being hit are welded with blade protection layer 8, and blade 2 is welded with hook shape protective layer 6 with the hub disk joint, and the forward position 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. wear-resisting centrifugal fan impeller; comprise shroud, blade, hub disk, reel, back disc protective layer, blade protection layer, dustproof striking plate and rivet; it is characterized in that: blade is a wing blade along the direction of wheel rotation, and shroud is an arc shaped surface, and hub disk is reinforced flat board.Blade is welded with protective layer, and hub disk and blade joint are welded with hook-shaped protective layer, and the blade forward position is welded with dustproof striking plate.
2. by the described a kind of wear-resisting centrifugal fan impeller of claim 1, it is characterized in that: the dustproof striking plate in blade forward position is given prominence to outside protective coating.
