Abstract:
This paper presents the study of influence of two-phase solid-liquid flow on the pressure of centrifugal pumps used in the coal processing plants in the Quảng Ninh. When the centrifugal pump is working, the solid phase often changes in the parameters of the solid particle components, thus greatly affecting on the working parameters of the pump, one of it is pressure* The results of the study much be used to improvmemt of using the pump.
