Abstract
The utility model discloses a centrifugal fan impeller, which comprises a soleplate (1) and a top cover (2), wherein a blade (3) is arranged between the soleplate (1) and the top cover, the soleplate (1) is of a plane annular plate, the blade (3) is of an arc panel, and the blade (3) is vertical to the soleplate (1); a plurality of welding indicators (4) along the arc direction of the blade (3) are arranged at an identical distance from each other at the inner side of the soleplate (1), the bottom part of the blade (3) is welded on the welding indicators (4), and the top part is welded on the top cover (2). The welding indicators which are matched with the shape of the blade are arranged on the soleplate, so the bottom part of the blade is welded on the soleplate, and the top part is welded on the top cover. The impeller is free from loosening during the running process, the movable balance value is free from being changed, the noise is reduced by six dB compared with the prior art, and the environment of the worker is improved. In addition, each part is made of the aluminum alloy, so the production is difficult to be deformed, the mechanical strength is high, and the service life is long.
Description
Technical field
The utility model relates to the impeller that uses on a kind of centrifugal blower, particularly centrifugal blower.
Background technique
In production practices, the use of centrifugal blower is very general, and the impeller that uses in the centrifugal blower all adopts on-link mode (OLM) at present, as the upper and lower sides at blade six pin is set respectively, then blade is plugged in the little slotted hole of base plate and top cover, carry out clubfoot again, press fixing.Adopt this plug in structure, make to be easy to generate after the blower fan running looseningly, dynamic balancing is not guaranteed, can send whistle during running.Its reason is: when clubfoot, when pressing, need only wherein a slice out of plumb in all blades, or press frock injustice, becoming flexible and whistle of whole impeller will appear.In addition, used base plate generally adopts plastic article to be riveted on the galvanized sheet at present, easily produces distortion, reduces mechanical strength, has influenced working life.
The model utility content
Technical problem to be solved in the utility model is, a kind of centrifugal blower fan blade wheel is provided, and this centrifugal blower fan blade wheel can effectively guarantee dynamic balancing, mechanical strength height, long service life.
The technical solution of the utility model: this centrifugal blower fan blade wheel, comprise base plate and top cover, between base plate and top cover, be provided with blade, described base plate is the plane annular plate, and blade is a curved panel, and blade is vertical with base plate; Inboard five equilibrium at base plate is provided with along the welding indicating head of blade arc trend, and the bottom of blade is welded on the welding indicating head, and welded top is on top cover.
Described blade has eight.
Corresponding every blade is provided with two welding indicating heads on the described base plate.
One arc section is arranged at the top of described blade, and top cover is the ring bodies of band arc surface, and arc section matches with the arc surface shape.
Described base plate, top cover and blade are Al-alloy products.
Compared with prior art, the utility model adopts the welding indicating head of the cooperation blade shape that suitable quantity is set on base plate, thereby the bottom of blade is welded on the base plate, and welded top is on top cover.So not only guarantee the vertical of blade and base plate easily, and because the blade of welding is more firm relatively, so impeller can not become flexible in operation process, the dynamic balancing value can not change, noise can will reduce by six decibels than the on-link mode (OLM) of available technology adopting, has improved workman's environment.In addition, the new aluminum alloy that adopts of this practicality prepares each parts, makes product not yielding, mechanical strength height, long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the blade structure for amplifying schematic representation that A makes progress in Fig. 1;
Fig. 3 is the structural representation of top cover.
Embodiment
One arc section 5 is arranged at the top of blade 3, and as shown in Figure 2, top cover 2 is the ring bodies of band arc surface 6, and as shown in Figure 3, arc section 5 matches with arc surface 6 shapes.
During installation, with blade 3 bottoms down (as among Fig. 2 away from a side of arc section 5), place perpendicular to base plate 1, and near welding indicating head 4, blade 3 and welding indicating head 4 are welded, treat that eight blades 3 all are vertically welded on the base plate 1 after, top cover 2 is covered on blade 3, the arc section 5 at blade 3 tops is matched with arc surface 6 on the top cover 2, and weld.Whole centrifugal blower fan blade wheel promptly installs, very simple and fast.
Claims (5)
