本文对伺服管主导型控制棒水力驱动机构的静态保持特性进行理论计算和分析，得到了水力驱动缸的静态保持流量及其随温度的变化规律。结果表明：在可变节流口间隙的稳态工作范围内，系统所需的静态保持流量很小；随温度的升高，流体密度降低，静态保持流量相应增大。倾斜工况下的系统静态保持流量范围较正常工况下的大，控制棒的保持特性更加稳定，抗扰动能力更强，满足舰船核动力装置规范的规定。

The analysis and calculation of static characteristic were carried out for servo-tube guided hydraulic control rod driving mechanism .The static holding flow rate and its variation law with temperature were acquired .The results indicate that the static holding flow rate needed is very small in steady working range of variable throttle orifice .The liquid density decreases with the increase of temperature ,and then the static holding flow rate increases accordingly .In inclining condition ,the range of static holding flow rate is augmented and the holding characteristic of control rod is more stable . Therefore , the resistance ability to perturbation is much stronger and is conformable to the criterion of nautical nuclear power device .
