Abstract


In this paper, on the basis of the advantages and disadvantages of fully articulated and compare various hydraulic design methods , reference our latest introduction of the AP1000 nuclear main pump hydraulic parameters , the first will be designed in accordance with a meta-theoretical speed coefficient method speed reduced by 1750r/min to 1450r/min design nuclear main pump flow components , to adapt to the needs of our 50Hz grid . Then its high temperature and pressure within the flow field using CFD software FLUENT numerical simulation of the full flow , reveal the characteristics of the internal flow field inside the nuclear main pump flow and secondary flow phenomena found in the junction of the impeller and the guide vanes , the water pressure The chamber outlet discovered reflux phenomenon . In order to clarify the impact of high temperature and pressure conditions for nuclear main pump hydraulic performance compared to the normal temperature and pressure conditions , and to map out the flow - efficiency , flow - lift curves . The simulation results show that the coefficient chart developed based on water as the working fluid is still applicable for nuclear main pump speed system using traditional method is feasible to design special nuclear main pump flow passage components . The high temperature and pressure , just change the working fluid physical parameters , no changes to the pump head , pump efficiency is slightly higher than normal temperature and pressure conditions . Also , according to the special structure of the AP1000 such a run-of- the mixed-flow pump , centrifugal pump radial vanes is the guide vane design guide vane design radial blades , comprehensive utilization of space vanes and conformal mapping , design methods , design the twisted blades guide vanes . Numerical simulation of the internal flow field of two guide vane model , results of the the surface twisted blade guide vanes better kinetic energy into pressure energy , head and efficiency are superior radial guide vane model . This article explores the nuclear main pump hydraulic design of the flow components , and achieved certain results , the optimal design for efficient nuclear main pump hydraulic model provides a useful reference .
