Hydraulic Improvement Design and Performance Analysis of Chemical Centrifugal Pump
This paper focuses on the design requirements of a centrifugal pump and completes the hydraulic model design and improvement.Through the comparison of more than 20 schemes,the optimal hydraulic design scheme for the pump is finally obtained.The calculation of the improved model shows that it can meet the design requirements and achieve a design point efficiency of over 83％.The prediction of cavitation performance has been completed.Through the analysis of cavitation performance at the design flow rate and the maximum operating flow rate,the pump NPSH3 is 5.6m under the maximum flow condition,meeting the design requirement of less than 7.5m under full flow conditions.The radial force characteristics of the impeller under two flow conditions are also analyzed,providing a reference for the force characteristics of pump bearing design.
