Design and analysis of pump casing and impeller using reverse engineering technique

Abstract Advances in three-dimensional (3D) laser measurement technology have resulted in progress in the field of Reverse Engineering. This study introduces a Reverse Engineering technique utilized to restore the initial design of a Pump Casing and its Impeller. This study provides a detailed understanding of the creation of the casing and its impeller 3D model by using the scanned model and its detailed steps, and a 3D deviation report is plotted in order to get a complete deviation idea between the scan data and the design extracted. The Casing and Impeller both have a range of upper and lower is +/− 0.75 mm for the deviation measurement. The Casing is that all points are within its limit, and it’s 100% for most points within its limit and the impeller is 90.9% for most points is in its limit.
