Methodology for the comprehensive optimization of a centrifugal pump with a magnetic coupling

Alexandra A. Zaytseva

A. Protopopov

Abstract: The article considers the design of a leakproof pump with a magnetic coupling operating on a chemical fluid. In this work the optimization of the pump assembly was carried out, including hydrostatic bearings and a magnetic coupling, using the STARCCM + simulation package. The throttle diameters optimal for this design are calculated. The author minimized the overflows in the auxiliary cooling paths of the coupling and the axial force on the pump rotor.

Increase in the service life and noise reduction in pumps is an important area in modern pump engineering. An attempt was made to introduce conjugate calculations in verifying correct operation of the mathematical model as the first step and identifying the main oscillation frequencies of the pump housing subsequently. The FSI interface was used in conjugate calculations at the boundary between liquid and solid media. The obtained oscillation signals were analyzed using the Fourier analysis to identify the main parasitic frequencies in the pump. It was expected that the main parasitic frequency would be the blade frequency. As a result of calculations, it became possible to verify correct operation of the mathematical model by applying it to the simplest model of a glass, which behavior could be easily explained. The mathematical model was tested on cantilever and multistage pumps, demonstrated good results and made it possible to establish that blade frequency was the main oscillation frequency.
