The calculation of the rotordynamic coefficients of a multistepped annular seal in hydraulic turbines is discussed in this paper. Based on the Hirs' turbulence lubrication theory and the bulk flow model, the governing equations for the flow in the seal are developed by using the Moody's friction equations. The governing equations are perturbed when the rotor and the stator are coaxial. The Runge Kutta integration method and the Newton Raphson iteration method are used to solve the perturbation equations....

本文首先在Hirs紊流润滑理论的基础上，采用体积流动模型及Moody摩擦方程建立起阶梯口环水封中流体流动的控制方程，将各个方程在转子与定子同心处进行摄动，采用Runge－Kuta积分法及迭代过程求解摄动方程，建立起水轮机阶梯式口环水封的转子动力特性系数的计算方法，为水轮发电机组轴系的动力学分析提供了必要的理论基础。

The purpose of opening the orifice was to sluice. The influence of fluctuating pressure upon the dam was another problem which was concerned by engineer. The paper analyzed Shuangkoudu masonry arch dam. The result indicated that the dam natural frequencies which consider the dam and the reservoir water interaction have great different from the preponderant frequencies of fluctuating pressure, the dam's first rank of vibration was far away from the high energy region of the fluctuating flow, so the sympathetic vibration would not take place.

坝身开设孔口主要目的是为了泄洪，泄洪时水流脉动压力对坝体结构动的影响是设计人员关心的另一课题，论文针对双口渡浆砌石拱坝进行了分析，研究结果表明：在考虑坝体一库水相互作用时坝体自振频率和水流脉动压力的优势频率相差较大，坝体的一阶振动远离脉动水流的高能量范围，二者不会发生共振。

杂质泵安装静试时泄漏机械弥缝安装调试好后，一般要进行静试，察看泄漏量如泄漏量较小，多为动环或静环弥缝圈存在问题；泄漏量较大时，则表白动、静环磨擦副间存在问题在开端察看泄漏量、判断泄漏部位的根蒂根基上，再手动盘车察看，若泄漏量无明显变化则静、动环弥缝圈有问题；如盘车时泄漏量有明显变化则可下定论是动、静环磨擦副存在问题；如泄漏介质沿轴向喷洒，则动环弥缝圈存在问题居多，泄漏介质向四周喷洒或从水冷却孔中漏出，则多为静环弥缝圈失效此外，泄漏通道也可同时存在，但一般有主次区分，只要察看细致，认识结构，一定能正确判断
