description: The subject of the graduate of qualification work is: âDevelopment and optimization of the flow part of the double-suction pumpâ
The aim of the final qualification work is to digitally model the flow part of a single-stage double-sided suction pump, with further optimization to achieve the required output parameters specified in the technical specifications.
The calculation of the main hydraulic and geometric parameters was performed using the method of A.Ð. Lomakin. in the past training course. After identifying the basic geometric parameters for 3D modeling, the SolidWorks and Ansys CFX software packages were used.
The SolidWorks program was used to develop all three-dimensional parts of a double-suction centrifugal pump (in particular, to build a three-dimensional model of the flow part, which includes the impeller, half-spiral inlet and spiral outlet), due to the large number of necessary tools for fulfilling the set tasks.
The Ansys software package is widely known in engineering circles and is necessary for performing hydrodynamic calculation of viscous fluid flow in the flow path of the pump under study, the possibility of constructing a grid in An-sys Meshing and building boundary conditions with the CFX- preprocessor, followed by visualization and obtaining a complete analysis of the work performed.
After analyzing the data obtained, we selected a method for optimizing the pump flow part, which consists in trimming the working wheel to achieve the necessary parameters specified in the technical task, and also the characteristics were constructed before and after optimization of the pump flow part. 
As an addition, a strength calculation of the pump rotor was made.
