| Abstract: | Hydraulic safe rod drives have simple structure, inherent reliability, and good economics. The hydraulic drive system of the safe rods was analyzed from the hydraulic view. The computing model of hydraulic safe rod drives was set up. Computing equations for raising and lowering the rods were derived. The model predicted the variation of the displacement, the clearance and the resistance coefficient over time. The results show the rod drives have the advantage of raising slow, lowering fast, speed ajustable. The performance of the drives meet the design requirements of reactor. |
