description: The work presents the calculation of the flow part of the centrifugal pump type CNS 720 600 for speeds 2900 rpm, 5800 rpm and 11400 rpm.
The review on similar pumps of foreign and Russian manufacturers with the description of the main parameters and working characteristics of pumps is conducted.
The description of designing of a flowing part in module Vista CPD which is a part of program complex Ansys is presented. Designed impellers calculated in Ansys CFX, the main predictive energy parameters are given.
Also described the process of constructing the geometry of impellers and diverters in CFTurbo, the process of sampling the calculation area in Meshing and TurboGrid mesh generators, as well as the calculation in Ansys CFX. The values obtained as a result of the calculation are given in tables, and visualization of the fluid flow in the flow parts is shown in the corresponding figures.
Vane and impeller variants have been developed, optimization has been carried out aimed at reducing losses in the outlet and increasing the pump stage head.
The first and intermediate stages of the 2900 rpm pump have been designed and calculated. Optimization of the outlet was carried out to reduce losses.
Designed and calculated impellers and vents for 5800 rpm and 11400 rpm pumps with fewer stages.
A comparison of the calculation results of impellers with different specific speed coefficients and different number of stages in pumps is presented.
