The angle of the diameter and diameter of the impeller center of circle to blade inner end in the upper conplane impeller center of circle to blade outer end portion, air inlet
Angle is 60-80 °, and flow inlet angle is the tangent line of the tangent line and its own camber line at the blade inner end in the inner circle at blade inner end
Angle, efflux angles is 20-40 °, efflux angles for the tangent line on cylindrical at blade outer end portion with the blade outer end portion its from
The angle of the tangent line of body camber line.
Preferably, the blade tip of impeller air inlet is provided with axial chamfer, axial chamfer is the leaf on front view
Piece end projects its angle for tilting lines and vertical direction formed on side view, the length of the horizontal direction of axial chamfer
Degree and the ratio of shroud height are 0.8-0.95.
Preferably, the end both sides of blade inner circle are respectively arranged with chamfering, and the radius of one of chamfering is 0.1mm-
0.5mm.The radius of another chamfering is 0.2mm-0.8mm.
Preferably, the height of shroud and the height of impeller ratio are 0.1-0.12,
Preferably, width of blade of the motor wheel hub diameter than small 0.25-0.35 times of the outside diameter of impeller.Increase air quantity.
Preferably, motor wheel hub is bowl-type, and the junction of blade and motor wheel hub is provided with arc angling.
The present invention is rational in infrastructure, can increase air quantity, improved efficiency, and reduces noise.
