| 摘 要： | 为检验余热排出泵的耐热冲击能力及其运行稳定性,基于能量守恒定律和冷态、热态回路不同工况的实际要求,设计了热冲击回路系统,并对主要设备进行热平衡计算,以确定设备型号.设计的热冲击回路系统包括冷态、热态两回路,通过三通阀的自动切换作用,进行冷态、热态条件的及时切换试验,以模拟核动力装置中余热排出泵的实际工作状况.试验结果表明,设计的余热排出泵热冲击回路系统可较为真实地模拟核动力装置实际运用情况;对设备进行的热平衡计算确定了主要设备型号;构建便捷的冷态、热态切换方式,可验证泵各部件的耐热冲击能力.

| Abstract: | In order to test heat shock resistance and operation stability of residual heat removal pump, thermal shock loop was designed based on energy conservation law and different working conditions of both cold-state and hot-state loops. The equipment types were determined by heat balance calculation. The thermal shock loop designed included both cold-state and hot-state loops,and in-time switching experiment from cold-state to hot-state was carried out with a three-way valve to simulate actual working conditions of residual heat removal pump. The experimental results show that the thermal shock loop system designed can really simulate practical working conditions of nuclear power plant. The equipment types are determined by heat balance calculation,and the heat shock resistance of pump parts is validated by means of convenient switching mode. |
