Commission method of the primary helium circulator of HTGR under variable resistance condition

  • 摘要: 高温气冷堆主氦风机调试期间,由于一回路阻力低于设计工况,因而主氦风机无法完成全转速范围性能测试。基于主氦风机的理论特性与相似原理开发主氦风机不同阻力工况调试参数的推算方法。结合主氦风机单体试验工况点,准确推算主氦风机冷态与热态性能试验的工况点参数,并指导完成高温气冷堆主氦风机全转速、满功率性能测试。通过对主氦风机调试与出厂试验结果的对比分析,验证本推算方法的可行性,并给出空气介质与氦气介质工况转换的修正因子。通过主氦风机调试与运行数据的对比分析,可以看出本文提供的主氦风机调试工况具有足够的包络性,能够覆盖高温气冷堆运行期间主氦风机的所有运行工况,证明了本文提供的变阻力工况主氦风机调试方法满足高温气冷堆主氦风机性能验证需求,可用于指导后续高温气冷堆的主氦风机调试工作。
