Blade and its china Axial flow impeller on sales. The blade includes a tip, a root, a leading edge, a trailing edge, an upper surface and a lower surface. The upper surface and the lower surface are oppositely arranged, and the tip, the The blade root, the leading edge and the trailing edge are arranged around the upper surface and the lower surface, and connect the upper surface and the lower surface. The blade can rotate around a rotation axis, so The rotation axis is perpendicular to a normal plane. The tip includes a tip base and a tip tail, the tip base is close to the leading edge, the tip tail is close to the trailing edge, and is opposite to the The tip base is tilted upward. The angle of attack of the chord of the tip tail is larger than the angle of attack of the chord of the tip base, where the angle of attack refers to the acute angle between the chord and the normal plane.

The above is a brief introduction to the small knowledge about the blade and its china Axial flow impeller on sales.
