    摘要： A seal is provided having a bristle pack with a first layer of bristles and a second layer of bristles. The bristle pack has at least one segment end. The first layer of bristles is configured to substantially surround the second layer of bristles, and at least one of the first layer of bristles has a first diameter. The second layer of bristles are located substantially in a center portion of the bristle pack, and at least one of the second layer of bristles has a second diameter. The first diameter is larger than the second diameter, and the first layer of bristles located near the at least one segment end are configured to protect the second layer of bristles located near the at least one segment end.

    摘要： A system controls net thrust of a steam turbine having a stepped rotating shaft. A first leak off line fluidly couples a first stage of a turbine section to a packing upstream of a stepped portion on the rotating shaft. A second leak off line fluidly couples a second stage of the turbine section that is subsequent to the first stage to a step area upstream of the stepped portion, and a connection line fluidly couples the first leak off line to the second leak off line. The lines include control valves such that a controller can actively control the net thrust by regulating thrust pressure on the stepped portion using steam from the first and second stages of the turbine section. The controller may also prevent damage to an active retractable seal using the control valves.

    摘要翻译： 系统控制具有阶梯式旋转轴的汽轮机的净推力。 第一泄漏线将涡轮部分的第一级与旋转轴上的阶梯部分的上游流体地联接。 第二泄漏线将第一阶段之后的涡轮部分的第二级流体地连接到台阶部分的上游的台阶区域，并且连接线将第一泄漏线路流体地耦合到第二泄漏线。 这些管线包括控制阀，使得控制器可以通过使用来自涡轮部分的第一和第二级的蒸汽来调节阶梯部分上的推力来主动地控制净推力。 控制器还可以使用控制阀防止对活动的可缩回密封件的损坏。
