Reverse Engineering of Pump Impeller Utilizing Rapid Prototyping Technology

ABSTRACT: Utilizing the manufacturing procedure of product mostly depended on physical characteristics, accessible facilities and desired specifications of product. In addition, procedure lead-time and economic issues are the effective parameters, which are investigable in planning procedure of every product. Pump manufacturing industries as one of the Precursor industries has also involved with some challenges in both design and manufacturing phases of production. The pump impellers as the main part of pumps are considered in this regard. The shape of impellers characterizes the performance and application of pump. Complicated blade shapes manufacturing is also needed to skilled workforce as well as implementing high technologies and equipment’s. 3D blade shapes impeller reverse engineering as the objective of this thesis is investigated in follow steps: a) Utilizing Rapid Prototyping method in reverse engineering as objective of this thesis has been studied and compared with conventional and CAD/CAM method with considering to time and cost issues. b) Pump hydraulic test analysis demonstrate the degree of compliance among reverse manufactured pump and the original pump. Parameters including Head (H) and Flow rate (Q) have been studied in case of conventional manufactured impeller and RP utilized impeller. The results have been investigated in two diagrams separately. Keywords: Reverse Engineering, Rapid Prototyping. …………………………………………………………………………………………………………………………
