Abstract
Face throttles are widely used as a functional element of seals or automatic balancing devices in pumps of different constructions. Hydrodynamic characteristics of such throttles are greatly influenced on rotor dynamics and the efficiency of the pump. It is necessary to know the pressure distribution in the face throttle gap with considering all possible effects that determine the fluid flow to calculate their hydrodynamic characteristics. The problem of viscous incompressible fluid flow through the face throttle of centrifugal pump automatic balancing device considering the throttle surfaces’ axial and angular displacements is considered. Equations of unsteady flow are solved. The inertia of the fluid is included. As a result, an analytical expression for the pressure distribution in the face gap is obtained. The influence of the local losses and the relative motion of the face throttle surfaces is analyzed. Hydrodynamic characteristics and coefficients of inertia, stiffness, and damping are calculated.
