| 摘 要： | 介绍了按照核电站冷却水循环泵的技术要求开发的核电站冷却水循环泵模型，给出了其结构方案；运用CFD方法设计开发了优秀的水力模型，并通过模型泵进行了验证测试；简要介绍了用于测试水力损失和观测流态的冷却水循环泵进水流道设计试验装置．验证测试的结果表明，该泵额定点效率达92％且高效区范围宽；泵运行噪声小，运行平稳；在额定工况点，设计的肘型进水流道水力损失小，仅为0．273m．该水力模型的综合指标达到了同类泵的先进水平，因此，我国核电站冷却水循环泵可实现国产化．

| Abstract: | An experimental model of circulating cooling water pump for nuclear power plant is designed according to the technology request. Its configuration is presented. The hydraulic model is designed using CFD technique and is validated through model experiment. The elbow-shaped inlet channel tester for testing hydraulic loss and observing its flow state is introduced. The experimental results show that its rated efficiency is 92% and the range of high efficiency area is broad. This pump can placidly run with a low noise. The hydraulic loss for elbow-shaped inlet channel is as small as 0.723 m. In conclusion, this hydraulic model has reached advanced level compared to congeneric pumps, and can be produced locally. |
