The influence of a combined pump’s auger-centrifugal stage inlet design on its vibration and pulsation states

Abstract


The paper is devoted to variations in the vibration and pulsation states of the auger-centrifugal stage of an NK series combined pump unit with different variants of its inlet design. Four variants of the inlet design are considered.
