description: The topic of final qualification work: "Parameters of mathematical model of calculation of flow in flow part of centrifugal pump with vane apparatus and prefabricated annular chamber". The object of research is a cantilever centrifugal pump. The subject of research is hydrodynamic, cavitation and strength calculations, performed by numerical method in the system ANSYS. This work is devoted to determining the optimal design parameters of the mathematical model of a centrifugal pump. For this purpose, the influence of time step on the results of hydrodynamic calculation in a non-stationary statement has been considered. We carried out cavitation and strength calculations. In the course of this work, the influence of time step on the calculation results was investigated. The optimal time step of 1Â° was recommended for this problem. It has been determined that local iterations practically do not influence the calculation accuracy, but considerably increase the time spent. The value of critical cavitation margin for the nominal mode of pump operation has been obtained. The static analysis for determination of strength properties of the impeller has been carried out. Visualization of stress and displacement intensity diagrams is made.
