摘要： The present disclosure relates to sealing the propeller shaft of a ship using a sealing having a group of lip seals arranged consecutively in a direction of the propeller shaft so that a seal chamber is created between adjacent lip seals. The pressure of the first seal chamber on the propeller side can be close to the pressure of the surrounding water at the propeller shaft level, and the pressure of the second seal chamber furthest from the propeller can be adjusted to a fixed value that is lower than the pressure of the first seal chamber. The pressure of a third chamber located between the first chamber and the second chamber can be adjustable by pressure regulation devices to a value between the pressure values of the first and the second chambers by adjusting the pressure loss caused by the flow of a liquid medium.
摘要翻译：本公开涉及使用具有一组在传动轴的方向上连续布置的一组唇形密封件的密封来密封船舶的传动轴，使得在相邻的唇形密封件之间形成密封室。螺旋桨一侧的第一密封室的压力可以接近传动轴水平面周围水的压力，并且距螺旋桨最远的第二密封室的压力可以调整到低于第一密封室的压力。位于第一室和第二室之间的第三室的压力可以通过调节由液体介质的流动引起的压力损失，通过压力调节装置调节到第一和第二室的压力值之间的值。

摘要： In reeling up of a paper web, a continuous paper web is reeled around a reeling core/reeling cores into successive machine reels or customer rolls. The actual control system controlling the reeling up process is supplemented with a substantially separate, model-based learning fault diagnostics. The fault diagnostics in a diagnostic state detects the malfunctions in components critical in view of the operation of the reel-up by monitoring measuring, control and actuating variables of the reel-up and by comparing them with a model formed during a learning state. In a fault tolerance state the fault diagnostics actively affects the measuring, control and actuating variables to maintain the function of the reel-up, and improve operating reliability.
摘要翻译：在卷起纸幅时，将连续的纸幅卷绕在卷取芯/缠绕芯上，以连续的机器卷或客户卷。控制卷取过程的实际控制系统补充了基本上单独的基于模型的学习故障诊断。诊断状态下的故障诊断通过监视卷取器的测量，控制和执行变量以及将其与在学习状态下形成的模型进行比较，来检测卷轴运行中关键部件的故障。在容错状态下，故障诊断主动影响测量，控制和启动变量，以维持卷取功能，并提高运行可靠性。
