摘　　要：通过分析CPR1000上充泵水力性能试验,发现导流体进口面积较大是轴功率偏高的主要原因,采取在各级导流体进口隔舌处焊接筋板的措施来改善上充泵水力性能。同时,借助有限元软件Ansys CFX对修改后方案的上充泵内部流场进行数值模拟,并与修改方案前实测的水力性能数据对比,然后对上充泵水力性能进行试验验证研究。结果表明,上充泵的轴功率控制在650k W以下,可达到满足鉴定试验大纲及技术规格书的要求,提高了上充泵的安全性和可靠性。Based on the analysis of CPR1000 charging pump hydraulic performance test,it is found that the large inlet area of the diversion body is the main reason for the high shaft power.Every piece of steel plate was welded to the inlet tongue respectively to improve the hydraulic performance of the charging pump.Firstly,with the help of Ansys CFX,the flow field inside the charging pump of the modified scheme was numerically simulated and compared with the measured hydraulic performance data before the scheme modification.Then the hydraulic performance of the charging pump was tested and verified.The results show that the shaft power of the charging pump is controlled below 650 kW,meeting the requirements of the evaluation test program and technical specification,and the safety and reliability of the charging pump is improved.
