Turbomachine element comprising an auxiliary sealing means, and method for testing this element

The invention relates to a turbomachine element comprising a stator (2), a rotor (1), and a first sealing means (9) for sealing between the rotor (1) and the stator (2) arranged to be active when the rotor is in the operating position of same around the axis of rotation (LL) thereof, the element being characterized in that it comprises an auxiliary pressure sealing means (20, 22), sealing between the rotor (1) and the stator (2), and is arranged so that the two sealing means are active when the rotor (1) is placed along the axis of rotation (LL) thereof during an assembly operation in a test position, the rotor (1) and the stator (2) forming, in said test position, an enclosure (8) between said two sealing means. 本发明涉及种涡轮机元件，该元件包括定子(2)、转子(1)和在转子(1)与定子(2)之间进行密封的第密封装置(9)，该第密封装置被布置成：当转子处于围绕其旋转轴线(LL)的运行位置时，该第密封装置生效；元件的特征在于，该元件包括辅助压力密封装置(20，22)，该辅助压力密封装置在转子(1)与定子(2)之间进行密封，并且被布置成：在装配操作期间，当转子(1)被沿着其旋转轴线(LL)置于测试位置时，两个密封装置生效；转子(1)与定子(2)在所述测试位置处形成了在所述两个密封装置之间的罩壳(8)。
