As the stirring flocculant blender shaft and Planet-cycloid reducer output shaft coupling with rigid links,but when flocculant viscosity greater mixing,stirring,flocculation Breeze leaf led forces and not rotating Uniform,resulting in persistent reducer gear damage and stirring shaft bending phenomena.

The results indicate that the antifriction layer sprayed on the surface of the worn impeller of blower can make the rejected impleller be reused and its service life.

The virtual mass method is used to research on the fan blade characteristic.

It was proved that the algorithm was stable and exact,and it could solve many problems of fan blade production.

According to the shape character of one fan blade, the forming steps was designed and the shape of related blank was modeled.

Flaw diagnosis for fan impeller at certain factory of Baosteel;

The extension of classification and classification structure is introduced,focusing on analysis of the unbalanced vibration fault type,fault causes,and the method of clearing fault of large-scale fan impeller and shaft system.
