Abstract：Due to the wide application of centrifugal pump, the solid-liquid two-phase flow has become a common problem in the study of flow characteristics in centrifugal pump. The addition of solid medium leads to the decline of head and efficiency, and even causes serious wear on the inner surface of the pump, which has a great impact on the operation performance of the centrifugal pump and reduces the continuous operation life of the centrifugal pump. In view of the above problems, the research status of solid-liquid two-phase flow in centrifugal pump from the aspects of solid-liquid two-phase flow characteristics and wear were introduced, and the main research methods and research results were summarized, including particle size, density, volume fraction and operating conditions of the centrifugal pump, which provides a certain reference and research basis for further optimizing hydraulic and structural design, improving the performance, reliability of solid-liquid two-phase flow in centrifugal pump, and wear condition.
