Abstract
The utility model discloses a high-pressure fan vane wheel. The high-pressure fan vane wheel comprises a wheel cover, vanes, a shaft disc, rivets and a wheel disc. The high-pressure fan vane wheel is characterized in that the wheel cover is welded with the vanes through electric welding, the vanes are welded with the wheel disc through electric welding, and the wheel disc is riveted with the shaft disc thought the rivets. The outer diameter of the vanes is 83.6 cm, and the circular arc radius of each vane is 56.5 cm. According to the high-pressure fan vane wheel, through the enlargement of the outer diameter of the vanes, under the condition that an outlet angle is ensured, the outer edge chord length of the vanes can be further enlarged, the circular arc radius of each vane can be enlarged, air flow is accelerated in a flow channel along a circular arc face, the radial speed and the peripheral speed of the air flow are improved, the dynamic pressure of a fan is increased, and the pressure of the fan and the flow of the fan are improved.
Description
Technical field
The utility model belongs to the blower fan field, relates in particular to a kind of high pressure positive blower impeller.
Background technique
The high pressure positive blower impeller is the GB type, and performance parameter is a fixed number, because existing design pipeline all has certain roughness, to resistance and the loss that air-flow causes, the performance of blower fan is caused damage.
Summary of the invention
The purpose of this utility model is to provide a kind of better performances and the higher high pressure positive blower impeller of efficient.
The purpose of this utility model is achieved in that described high pressure positive blower impeller, comprises wheel cap, blade, reel, rivet and wheel disc, its structural feature is that wheel cap and blade weld together with electric welding, and blade and wheel disc weld together with electric welding, and wheel disc and reel are with rivet together.
Described high pressure positive blower impeller, its characteristics are that the outer diameter of blade is 83.6 centimetres, and the radius of arc of blade is 56.5 centimetres.
The utlity model has following advantage: the utility model is by strengthening the blade outer diameter, under the situation that guarantees exit angle, also can strengthen blade outer rim chord length, increase the blade radius of arc, air-flow is quickened in runner along arc surface, improved the radial velocity and the peripheral velocity of air-flow, increase the dynamic pressure of blower fan, improve the pressure and the flow of blower fan, guaranteed the use value of blower fan.
Description of drawings
Fig. 1 is the structural representation after the partly cut-away of the present utility model.
Fig. 2 is a shaft section structural representation of the present utility model.
Embodiment
Below in conjunction with example the utility model is elaborated:
As depicted in figs. 1 and 2, high pressure positive blower impeller described in the utility model, comprise wheel cap 1, blade 2, reel 3, rivet 4 and wheel disc 5, its structural feature is that wheel cap 1 welds together with blade 2 usefulness electric welding, blade 2 welds together with wheel disc 5 usefulness electric welding, and wheel disc 5 is riveted together with reel 3 usefulness rivets 4.Drive wheel disc 5 by rivet 4 when reel 3 rotates, wheel disc 5 drives blade 2 again, and blade 2 drives wheel cap 1 again, and whole like this high pressure positive blower impeller just rotates.Air-flow just enters through blade 2 from wheel cap 1 interior round mouth, and round mouth flows out outside wheel cap 1 and wheel disc 5 again, has finished the air-flow accelerating process.
