Structure Reverse Design and Abrasion-Resistant Performance of Submersible Mixer’s Impeller Based on 3D Solid Model
In a wastewater treatment plant, there are some problems that the impellers of submersible mixers were damaged with abrasion and the impellers’ spare parts must be imported. To solve this problem and realize domestic manufacture, based on reverse engineering theory, utilizing three coordinates measuring machine and applications of Surface and Pro/E, then the Pro/E software was used to develop the impeller solid model. The gained impeller model accords with the physical one with high accuracy. By using this model, the manufacture of its mould and research on abrasion-resistant performance as well as the implementation of domestic manufacture of its parts are completed. The new impeller has been employed in this plant and passed field running experiment. The results indicate that its mixing and propelling performance is excellent and abrasion does not happen in more than three months. It has prominent economic and social benefit.
