Design and Modelling of a Centrifugal Pump Using Autodesk Inventor Professional

Abstract

Abstract Centrifugal pumps find wide-ranging applications across various fields, yet the majority of these pumps continue to be produced using conventional manufacturing methods. These methods involve processes such as milling, cutting, and drilling, which, while effective, are less inclined towards achieving energy, environmental, and economic sustainability. This has spurred researchers to explore innovative approaches to enhance the sustainability of production processes. One notable advantage of 3D printing lies in its capacity for rapid prototyping. This term denotes the ability to swiftly fabricate, design, and evaluate a bespoke component in the shortest possible time. The driving force behind this research endeavor is to furnish comprehensive guidance on the design and modelling of a centrifugal pump utilizing Autodesk Inventor Professional software. To ensure synchronized operation, a coupling unit was employed to link the pump and motor shafts, ensuring they rotate at identical speeds and within the same plane. This unit plays a critical role in transmitting both speed and torque. The modelling of the impeller, the pivotal component of the centrifugal pump, entailed the following steps: creating a model for the lower flared section, fashioning the upper flared part, shaping the impeller blades, generating a circular series of blades to yield the remaining seven, designing a reinforcement solid for secure attachment to the axis, sculpting the lower wear ring, and fashioning the central aperture to accommodate the rotating shaft.
