【摘要】 西安脉冲堆脉冲控制棒驱动机构是实现反应堆脉冲运行的关键设备。该机构采用滚珠丝杠副的传动方式,通过气压缸实现控制棒的脉冲发射。脉冲控制棒驱动机构具有全行程脉冲时间短、结构简单、维修方便的特点。试验表明:脉冲控制棒驱动机构最大负荷大于300N,全行程脉冲时间小于100ms,落棒时间小于1.2s,寿命大于4000次脉冲发射运行,平均无故障时间大于400次脉冲发射运行。该机构已成功应用于西安脉冲堆。更多还原

【Abstract】 Pulse control rod drive mechanism In Xi抋n Pulsed Reactor is the key equipment to implement the pulsing operation. It takes ball screws as drive machine. It use pressure cylinder to implement pulse launch of control rod. The feature are: the pulse time of whole journey is short, the configuration is simple, the maintain is convenient. The experiments shows: the largest load is more than 300N, pulse launch time is less than 100ms; frequency of pulse launch without stoppage is more than 400 times. And the life of pulse launch is more than 4000 times. The machine has been used for Xi抋n Pulse Reactor. Successfully.更多还原
