分析了２００ＭＷ核供热堆控制棒水力驱动系统（ＨＤＳＣＲ）的设计特点；系统中主要设备（槽孔式水力步进缸和组合阀）的设计特点及特性；旁路自调节结构的设计及其高温下的补偿作用以及系统温度特性的实验结果。经对实验结果的分析表明：ＨＤＳＣＲ和各设备的设计合理、运行可靠；各设备的设计不仅降低了设备的加工难度及安装难度，而且改善了系统的温度特性；系统完全能满足２００ＭＷ核供热堆对控制棒驱动机构的要求
The design features of HDSCR for the control rods of 200 MW nuclear reactor are analyzed. The design features and characteristics of the main equipment (slotted hydraulic stepping cylinder and combination valve) in the system; the design of bypass self-adjusting structure and its The compensation effect under high temperature and the experimental result of the temperature characteristic of the system. The analysis of the experimental results shows that: HDSCR and each device design is reasonable and reliable operation; the design of each device not only reduces the difficulty of equipment processing and installation, but also improves the temperature characteristics of the system; the system can fully meet the requirements of 200MW nuclear heating Heap on the control rod drive mechanism requirements
