| 摘 要： | 根据控制棒水压驱动机构水压缸活塞环密封结构的特点,分析了水压缸活塞环的泄漏途径,建立了活塞环密封泄漏流阻的理论计算模型,并结合水压缸活塞环密封处的压差计算模型,推导出水压缸密封结构的流阻计算公式。利用控制棒水压驱动机构单缸性能实验的结果,拟合求得了流阻公式中的系数,并将公式计算流阻与实验结果进行了对比。结果表明:在实验工况下,二者吻合得很好。研究结果为控制棒水压驱动机构水压缸活塞环密封结构的设计和分析提供了理论基础。

| Abstract: | According to the control rod hydraulic drive mechanism (CRHDM) and the characteristics of its hydraulic cylinder seal structure, the leaking ways of the hydraulic cylinder piston ring seal were analysed, its theoretical calculation model was built and its flow resistance formula based on the calculation model of differential pressure at the hydraulic cylinder piston ring seal was deduced. By analyzing the results of the CRHDM single cylinder experiment, constants in the formula of the flow resistance were obtained. Under the experimental condition, results from the formula and the experiment tally with each other. The formula and analysis would be helpful for the theoretical (analysis) and engineering design of the hydraulic (cylinder) piston ring seal structure. |
