Abstract
The utility model discloses a coil pipe air blower impeller including two end coils, a middle disc and a plurality of blades, both ends of the blades are respectively fixedly connected to the end coils; the blades are fixedly connected to the middle disc, the middle disc is arranged in the middle part of the blades; the middle disc is peripherally distributed with a plurality of through holes. The coil pipe air blower impeller in the utility model allows the air flow in the impeller to be smoother by additionally providing with the fan-shaped through holes on the middle disc, thereby effectively improving the aerodynamic performance of the impeller.
Description
Technical field
The utility model relates to a kind of impeller, is specifically related to a kind of coil pipe draught fan impeller.
Background technique
Existing coil pipe draught fan impeller, its mid-game does not have through hole, and mid-game is divided into two two-part that do not communicate with impeller, so the aerodynamic performance of impeller is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of coil pipe draught fan impeller, and it can improve the aerodynamic performance of impeller.
For solving the problems of the technologies described above, the technical solution of the utility model coil pipe draught fan impeller is:
Comprising two end circles, mid-game, a plurality of blade, fixedlys connected with the end circle respectively in the two ends of blade; Blade is fixedlyed connected with mid-game, and mid-game is arranged at the middle part of blade; Be evenly distributed in a plurality of through holes in the described mid-game.
The center line of described two end circles and mid-game is on same axis.
Described through hole is fan-shaped.
The technique effect that the utility model can reach is:
The utility model makes the impeller internal gas flow smooth more by increase fan-shaped pylone in mid-game, thereby can improve the aerodynamic performance of impeller effectively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the schematic representation of the utility model coil pipe draught fan impeller;
Fig. 2 is a sectional view of the present utility model;
Fig. 3 is the schematic representation of mid-game of the present utility model.
Description of reference numerals among the figure: end circle 1, mid-game 2, blade 3, through hole 21.
Embodiment
As shown in Figure 1 and Figure 2, the utility model coil pipe draught fan impeller comprises two end circles 1, mid-game 2, a plurality of blade 3, fixedlys connected with end circle 1l respectively in the two ends of blade 3; Blade 3 is fixedlyed connected with mid-game 2 through spinning, and mid-game 2 is arranged at the middle part of blade 3;
As shown in Figure 3, be evenly distributed in a plurality of fan-shaped through holes 21 in the mid-game 2;
Two center lines of holding circle 1 and mid-game 2 are on same axis.
The utility model increases fan-shaped pylone 21 in mid-game 2 on the basis that guarantees rigidity, make the impeller internal gas flow smooth more.
Internal gas flow of the present utility model is more smooth, can improve the aerodynamic performance of impeller effectively.
The utility model belongs to two air intake coil pipe draught fan impellers.
