Description
Technical field
The present invention relates to ventilation equipment, particularly relate to a kind of impeller and ventilator.
Background technique
Ventilator is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, 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, be folded with multiple blade between described shroud and hub disk, described shroud is provided with intake grill;
Described blade comprises flat plate section and airfoil section, and described airfoil section is formed with cavity, and described airfoil section is arranged near described intake grill.
The invention provides a kind of ventilator, comprise impeller provided by the present invention.
Based on above-mentioned, impeller provided by the invention, because blade has airfoil section, therefore, it is possible to improve the efficiency of impeller, blade also has flat plate section simultaneously, therefore saves material, machine shaping is convenient and time-saving.

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, is folded with multiple blade 103 between described shroud 101 and hub disk 102, 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 is arranged near described intake grill 104.
In the present embodiment, because blade 103 has airfoil section 106, therefore, it is possible to 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 line, described multiple blade 103 is uniformly distributed along the circumference of described impeller.
In the present embodiment, preferably, blade 103 is the blade 103 be made up of plate, described plate one end bending and form described cavity 107 using as described airfoil section 106, and the other end of described plate is as described flat plate section 105.Thus, blade 103 machine shaping is more convenient and save material, further reduces impeller cost.
In the present embodiment, preferably, the orthographic projection in shroud 101 front 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, preferably, outlet air end 109 is provided with outlet air surface 111, and described outlet air surface 111 bends towards described air intake 108.Fluency and stability that gas spreads at outlet air surface 111 can be increased thus, reduce the gas energy loss because disturbance, mixed flow cause.
In the present embodiment, preferably, blade 103 has the blade face of cutting sth. askew, and with the linear change of the angle of the inlet angle making blade 103, makes the fluidity of blade 103 better, improves the efficiency of impeller further.
In the present embodiment, preferably, the blade face of blade 103 is made up of multiple continuous print arc surface, to make the fluidity of blade 103 better, improves the efficiency of impeller further.
In the present embodiment, preferably, the exit angle that blade 103 and hub disk 102 are formed is 29 ± 2 degree, and the inlet angle that blade 103 and hub disk 102 are formed is 16 ± 1 degree, and the inlet angle that blade 103 and shroud 101 are formed is 21 ± 1 degree.Impeller is made to have better efficiency thus.
The embodiment of the present invention provides a kind of ventilator, comprises the impeller described in any embodiment of the present invention.Because blade 103 has airfoil section 106, therefore, it is possible to 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.
Last it is noted that above each embodiment is only in order to illustrate technological scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristics; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technological scheme.
