Abstract
The utility model provides a forward wing type fan impeller relating to the technical field of a forward wing type fan impeller applied to the air blowing occasion of a high-pressure air field. The forward wing type fan impeller comprises a shaft and a plurality of big vanes connected with the shaft, wherein the position of an outlet of the fan impeller is provided with a small vane, one sides of the big vanes opposite to the movement directions of the big vanes are connected with a panel, a plurality of supporting components are arranged between the big vanes and the panel, and the big vanes are welded with a combination part of the panel, which is far away from one end of the shaft. The utility model realizes the aims of simple structure, good use effect and long service life.
Description
Technical field
The utility model relates to the technical field of the forward wing type fan impeller that is applied in high pressure air field air blast occasion.
Background technique
Because the main feature of blower fan is rotating speed height, impeller linear velocity height, widely applies forward direction blade blower fan in pressurized gas air blast occasion.Exactly because also high rotating speed, so higher requirement has been proposed also the intensity of impeller.For there not being corrosive gas, generally adopt high-intensity carbon steel material, but carbon steel material is not suitable for the environment of corrosive gas again, have the main stainless steel material that uses under the environment of corrosive gas.Though stainless steel material can solve the problem of corrosion resistance, insufficient strength, working life is not long.
Summary of the invention
The utility model purpose provides a kind of simple in structure, and using effect is good, the forward wing type fan impeller of long service life.
The utility model adopts following technological scheme for achieving the above object:
A kind of forward wing type fan impeller, comprise axle, some big blades that are connected with axle, outlet port at draught fan impeller is provided with small leaf, one side of the big blade opposite with big blade movement direction connects panel, between big blade and the panel several supporting elements are set, the connecting part welding of big blade and the abaxial end of panel.
Supporting element of the present utility model respectively with big blade, panel plug welding.
The utility model adopts technique scheme, compared with prior art have following advantage: the utility model installs panel additional at the non-working surface of big blade, connects by supporting element, and supporting element plays the effect of stiffening rib, improve the intensity of stainless steel material, prolonged working life.The packaged type of wing blade is adopted in the connecting part of big blade of the present utility model and panel, can not occur the situation of resistance when impeller uses like this, and using effect is good, and simple in structure.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is elaborated:
As shown in Figure 1, a kind of forward wing type fan impeller, comprise shroud, some big blades 2 that are connected with hub disk, in the outlet port of draught fan impeller small leaf 1 is set, a side that it is characterized in that the big blade 2 opposite with big blade 2 moving direction connects panel 4, make big blade wind inlet place form the wing blade shape, between big blade 2 and the panel 4 several supporting elements 3 are set, big blade 2 and connecting part 5 welding of panel 4 away from an end in axle center.
Supporting element 3 of the present utility model respectively with big blade 2, panel 4 plug weldings.
The utility model increases a panel 4 at the non-working surface of big blade 2, form upper blade and lower blade structure, between the blade supporting element 3 being set up and down, play the effect of stiffening rib then, supporting element 3 adopts the plug welding mode to handle, and firm is fixed on up and down between the blade.Because big blade has adopted wing blade, has increased the rigidity of big blade greatly, has improved the intensity of impeller.Well solved the problem of stainless steel material strength deficiency.
Claims (2)
1. forward wing type fan impeller, comprise shroud, the some big blades (2) that are connected with hub disk, small leaf (1) is set in the outlet port of draught fan impeller, a side that it is characterized in that the big blade (2) opposite with big blade (2) moving direction connects panel (4), between big blade (2) and the panel (4) several supporting elements (3) are set, big blade (2) and connecting part (5) welding of panel (4) away from an end in axle center.
