The impeller and the ventilator can improve impeller efficiency.
Description
Technical field
The present invention relates to ventilation equipment, relate in particular to a kind of impeller and ventilator.
Background technique
Ventilator is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure, and impeller is the vitals in ventilator.
Double shrouded wheel comprises shroud and hub disk, is fixedly connected with plate blade between shroud and hub disk.The impeller adiabatic efficiency of prior art is lower.
Summary of the invention
The invention provides a kind of impeller and ventilator, to raise the efficiency.
The invention provides a kind of impeller, comprise shroud and hub disk, between described shroud and hub disk, be folded with a plurality of blades, described shroud is provided with intake grill;

Embodiment
Please refer to Fig. 1-4, the embodiment of the present invention provides a kind of impeller, comprises shroud 101 and hub disk 102, between described shroud 101 and hub disk 102, is folded with a plurality of blades 103, and described shroud 101 is provided with intake grill 104; Described blade 103 comprises flat plate section 105 and airfoil section 106, and described airfoil section 106 is formed with cavity 107, and described airfoil section 106 arranges near described intake grill 104.
Therefore in the present embodiment, because blade 103 has airfoil section 106, can improve the efficiency of impeller, blade 103 also has flat plate section 105 simultaneously, therefore saves material, machine shaping is convenient and time-saving, cost is low.Wherein, described shroud 101 and hub disk 102 coaxial lines, described a plurality of blades 103 circumferentially being uniformly distributed along described impeller.
In the present embodiment, preferred, the blade 103 of blade 103 for being made by plate, described plate one end bending and form described cavity 107 and using as described airfoil section 106, the other end of described plate is as described flat plate section 105.Thus, blade 103 machine shapings are more convenient and save material, further reduce the impeller cost.
In the present embodiment, preferred, the orthographic projection in shroud 101 fronts is ring, and the inner circle of described ring is air intake 108, and the cylindrical of described ring is outlet air end 109; The axial cross section of shroud 101 is trapezoidal, and described trapezoidal upper base is described air intake 108, and described trapezoidal bottom is described outlet air end 109, and described trapezoidal waist 110 is the arc of indent.Thus, make the intensity of shroud 101 better.
In the present embodiment, preferred, outlet air end 109 is provided with outlet air surface 111, and described outlet air surface 111 is towards described air intake 108 bendings.Can increase thus fluency and the stability of gas in outlet air surface 111 diffusions, reduce the gas energy loss caused due to disturbance, mixed flow.
In the present embodiment, preferred, blade 103 has the blade face of cutting sth. askew, so that the linear variation of the angle of the inlet angle of blade 103 makes the fluidity of blade 103 better, further improves the efficiency of impeller.
In the present embodiment, preferred, the blade face of blade 103 is comprised of a plurality of continuous arc surfaces, so that the fluidity of blade 103 is better, further improves the efficiency of impeller.
In the present embodiment, preferred, blade 103 is 29 ± 2 degree with the exit angle that hub disk 102 forms, and blade 103 is 16 ± 1 degree with the inlet angle that hub disk 102 forms, and blade 103 is 21 ± 1 degree with the inlet angle that shroud 101 forms.Make thus impeller have better efficiency.
The embodiment of the present invention provides a kind of ventilator, comprises the described impeller of any embodiment of the present invention.Because blade 103 has airfoil section 106, therefore can improve the efficiency of impeller, blade 103 also has flat plate section 105 simultaneously, therefore saves material, machine shaping is convenient and time-saving, cost is low.
Finally it should be noted that: above each embodiment, only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to aforementioned each embodiment, the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, or some or all of technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of various embodiments of the present invention technological scheme.
