摘　　要：船用反应堆顶盖顶升作业具有大吨位、非均载、小流量、短行程的特点,采用闭环同步控制回路的液压传动系统利用分油装置"等量、定量"地给液压缸注油,在控制系统的配合下,实现反应堆顶盖同步自动顶升,顶升过程水平度不低于0.2%。The synchronizing lift work of reactor top cover used for submarine has the character of big weight,non uniform load,small flow and short stroke.A hydraulic Drive System adopted closed-loop synchronism control circuit uses oil dividing device for injecting oil into hydro-cylinders with ＂equivalent flow and determinate flow＂.Moreover,with coordinating control system,it realizes synchronizing automatic lift of reactor top cover.And during the process,the levelness is higher than 0.2％.
