Calculation of the Characteristics of the Multi-gap Seal of the Centrifugal Pump, in Depend-ence on the Chambers' Sizes

Year: 2020

Type: article

Abstract: The paper presents the results of an experimental research and a numerical calculation of a multi-gap seal of a centrifugal pump. The experimental research allowed to obtain the characteristics? performance of the multi-gap seal at different operating modes, in dependence on the axial size of the chambers, pressure distributions? changes, and a leakage from the seal. Using finite volume methods, values of radial hydrostatic forces, pressure distribu-tions and leakage values were obtained. The results of the numerical calculation were compared with the results of the experiment, which showed that they matched.
