The blade and the customized Axial flow impeller price using the same. The blade includes a blade tip, a blade root, a leading edge, a trailing edge, an upper surface and a lower surface. The upper surface and the lower surface are oppositely arranged, the blade 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, and the The axis of rotation 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 raised 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 present application The blades can provide larger air volume, higher static pressure, and higher efficiency.

The above is a brief introduction to the small knowledge about the blade and its customized Axial flow impeller price.
