“…Oscillations of the rotor along the y axis are caused by two force reactions of the liquid layer, designated R c and W . The expression of the force R c , depending on the displacement of the rotor, is given in [10], in which the load was assumed to be applied strictly along the vertical axis y. The expression for the force W caused by the hydrodynamic reaction of the liquid layer to the acceleration of the rotor is obtained in Appendix 1.…”

“…Малорасходные центробежные насосы нашли свое применение во многих от-раслях промышленности, поэтому существует достаточно много источников литературы [1][2][3][4], в которых подробно описаны расчеты различных параметров этих насосов. Однако вопросы, связанные с нахождением установившейся угло-вой скоростью ротора насоса, освещены недостаточно.…”
