Axial Fan basic version

"Axial Fan" can be divided into the following basic types: the cabinet is only one impeller, no guide vanes. This is the simplest type, easy to produce this type of energy loss. Therefore, this type is only available in low-pressure turbines. It is installed in a housing impeller and a stationary outlet guide vane. In the installation of the impeller outlet guide vanes. Because this type of installation of the vanes reduce the losses caused by the rotational movement, improve efficiency, and thus commonly used in high-pressure fans and water pumps. It is installed in a housing and impeller - fixed inlet guide vanes. Fluid axially into the guide vanes and, after rotation of the impeller vanes produces the opposite direction of the rotational speed, which produce antiferromagnetic spin. This type of guide vanes, the relative velocity w1 fluid into the impeller than Vane type is large, and therefore energy loss is large, less efficient.
