This paper presents a test bed suitable for studying the influence of gas-liquid solid multiphase flow on the performance of a centrifugal pump, and elaborates on the conception, design plan and implementation steps of the test system. The design focuses on the flow characteristics of gas-liquid solid and three phases and the nature and characteristics of each phase. In combination with the start-up and operation of centrifugal pumps, the research on centrifugal pumps and multiphase flow is explored. The follow-up tests show that the system Design is simple, practical and innovative.
