Abstract
The utility model relates to the blade field and specifically relates to an L-shaped impeller liner plate with wear-resistance. The L-shaped impeller liner plate with wear-resistance is characterized in that an upper L-shaped liner plate with wear-resistance is welded onto an upper connection between a blade and a central reel; and a lower L-shaped liner plate with wear-resistance is welded onto an upper connection between a blade and a central reel. With the technical scheme of the L-shaped impeller liner plate with wear-resistance, numbers of liner plates with wear-resistance of a straight-plate type impeller needing wear-resisting treatment are reduced; amounts and lengths of weld joints are also reduced; the technology of the L-shaped impeller liner plate with wear-resistance is simple, thereby improving production efficiency; and the L-shaped impeller liner plate with wear-resistance protects main weld joints between the blade and the central reel.
Description
Technical field
The utility model relates to the blade field, is a kind of L shaped impeller abrasion-proof liner plate.。
Background technique
When dust loading is higher in the working medium of centrifugal blower, all can take Wear-resistant Treatment to impeller, usually to the peripheral region installation abrasion-proof backing block of part area, impeller mid-game and the blade weld of the working surface of impeller blade and non-working surface.The abrasion-proof backing block of the abrasion-proof backing block of front side of vane, blade non-working surface, the abrasion-proof backing block of mid-game are all independently made, are installed, and the abrasion-proof backing block of mid-game has better manufacturability that it is divided into 3 sections for satisfying, therefore each piece blade all has 5 abrasion-proof backing blocks, and abrasion-proof backing block quantity is many, making is loaded down with trivial details, manufacturing efficiency is low; What adopt because of the mounting type of abrasion-proof backing block and blade and shroud again is welding, weld seam quantity is many, weld seam is always grown up, the built-up welding zone greatly, thereby cause that heat distortion amount is big, thereby influence the quality of product.
Summary of the invention
The purpose of this utility model is that a kind of L shaped impeller abrasion-proof liner plate will be provided.
The technical solution of the utility model is: it is characterized in that being welded with L shaped abrasion-proof backing block in joint in blade and the mid-game, the joint is welded with L shaped abrasion-proof backing block down under blade and mid-game.
Owing to adopted technique scheme; the abrasion-proof backing block quantity of the board-type impeller that need do Wear-resistant Treatment is reduced; also reduced simultaneously quantity and the length of weld seam, technology is simple, improved manufacturing efficiency, and the main weld of blade and mid-game has been played protective action.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the drawings: 1, go up L shaped abrasion-proof backing block; 2, blade; 3, following L shaped abrasion-proof backing block; 4, mid-game.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
In Fig. 1, the joint is welded with L shaped abrasion-proof backing block 1 in blade 2 and mid-game 4, is welded with L shaped abrasion-proof backing block 3 down in blade 2 and 4 times joints of mid-game.
To go up L shaped abrasion-proof backing block 1 by product size put sheep out to pasture expansion, bending and forming, will go up L shaped abrasion-proof backing block I by installation dimension and weld seam requirement and be installed on the impeller.
To descend L shaped abrasion-proof backing block 3 by product size put sheep out to pasture expansion, bending and forming, will descend L shaped abrasion-proof backing block 3 to be installed on the impeller by installation dimension and weld seam requirement.
Claims (1)
