Abstract
The utility model relates to a vane insertion type ventilation blade wheel, which comprises a blade wheel seat and a ventilation vane which is composed straight line ventilation vane segments and curved line ventilation vane segments. The blade wheel seat is provided with 2 to 24 through grooves which use the circle center of the blade wheel seat as the center and are equally distributed in the radial direction; the straight line ventilation vane segments with the corresponding number with the through grooves are inlaid in the through grooves of the blade wheel seat, and all the curved line ventilation vane segments can form a ventilation blade wheel. Since the ventilation vane is sheared by cold-rolled steel sheets and is formed by punching, the strength, the dimensional precision and the surface roughness can be ensured after the blade wheel base is conducted with the mechanical process and the heat treatment by forged steel or cast steel; after the through grooves are milled, the vane can be accurately positioned. The utility model can be popularized and used on a centrifugal compressor.
Description
The utility model relates to the impeller of centrifugal compressor.
Impeller inducer is the critical component of centrifugal compressor, and the wind guiding blade of general impeller inducer and impeller base are monolithic constructions, and its processing method generally has following two kinds.
1. the monoblock steel are milled into type with formed cutter on numerical control machine tool: its machining accuracy of this processing method and surface roughness can guarantee fully.The factor control milling machine costs an arm and a leg, and is not that general machinery plant all possesses this equipment; Promptly enable to process with numerical control milling machine, processing cost is high, and the user is difficult to bear, and is not easy to the popularization of product.
2. precision casting impeller: it is low that this processing method is made the impeller cost, and appointed condition is less demanding, is easy to the popularization of product.But also be subjected to the restriction of following condition, one is because blade approaches (is 2mm as thickness), and the restriction of molten iron temperature and molten iron flowability during casting very easily causes molten iron stream to cause waste product less than whole blade, even can't cast at all; It two promptly enables smoothly accurate casting, but it is surperficial good that the blade surface after the casting, the total too late cutting of the surface roughness of impeller base curved surface are crossed, and influences the resistance that fluid flows, if casting back impeller base curved surface is polished again, not only time-consuming but also require great effort, effect is also very poor.
The purpose of this utility model is: wind guiding blade and impeller base are processed the blade groove embedding formula impeller inducer that laggard luggage is joined respectively, can solve the problem that exists in the background technique.
For achieving the above object, the technical solution adopted in the utility model is: it comprises impeller base and wind guiding blade, having 2～24 on the impeller base is the groove center, that distribute by five equilibrium radially with the impeller base center of circle, be embedded in the groove of impeller base with the wind guiding blade of groove respective grooves number, form with reinforcement of weld.
Wind guiding blade is to be combined by straight line wind guiding blade section and curve wind guiding blade section, and straight line wind guiding blade section is embedded in the groove of impeller base.
Height, width and the bending direction of every its curved surface of curve wind guiding blade section are all identical, are embedded in the groove by straight line wind guiding blade section, and whole curve wind guiding blade sections constitutes inducer.
Also all its curved surfaces of curve wind guiding blade section can be divided into two kinds of different heights, but both width are all identical with bending direction, are embedded in the groove by straight line wind guiding blade section is alternate, whole curve wind guiding blade sections constitutes inducer.
The useful effect that the utility model compared with prior art has is:
Wind guiding blade with cold rolled sheet shear, impact briquetting, surface roughness is good, intensity is also high;
Impeller base with forged steel or cast steel after machining and heat treatment, can proof strength, dimensional accuracy and surface roughness requirement;
3. the groove on the impeller base is convenient to fixedly straight line wind guiding blade section through milling, and the location is correct.
Therefore, the utility model can be applicable on centrifugal compressor.
Below in conjunction with accompanying drawing, the utility model is explained in detail.
Description of drawings:
Fig. 1. structural representation of the present utility model;
Fig. 2. A-A sectional view of the present utility model;
Fig. 3. the wind guiding blade plan view;
Fig. 4. wind guiding blade B is to view;
Fig. 5. groove distribution map on the impeller base;
Fig. 6. impeller base C-C sectional view.
As Fig. 1, Fig. 2, Fig. 5, shown in Figure 6, having 16 on the impeller base 1 is groove 6 center, that distribute by five equilibrium radially with the impeller base center of circle, is embedded in the groove 6 of impeller base with the wind guiding blade of groove 6 respective grooves numbers, forms with reinforcement of weld.
As Fig. 3. shown in Figure 4, wind guiding blade is combined by straight line wind guiding blade section 2 and curve wind guiding blade section 3.As Fig. 2, shown in Figure 6, straight line wind guiding blade section 2,4 is embedded in the groove 6 of impeller base 1.
As shown in Figure 1 and Figure 2, curve wind guiding blade section 3,5 its curved surfaces are divided into two kinds of different heights, the height of curve wind guiding blade section 3 is greater than the height of curve wind guiding blade section 5, but both width are all identical with bending direction, by straight line wind guiding blade section 2 and straight line wind guiding blade section 4 alternate being embedded in the groove 6, whole curve wind guiding blade sections constitutes inducer.
