The present invention relates to a method for easily and repeatedly separating and connecting sections (6a, 6b) of a pipe (6) for a hot and highly pressurised liquid (D) such as a steam pipe. This method uses a dual-wall flanged joint (1) that comprises an outer flange (2) and an inner flange (2) defining a gap (4) in which a cooling fluid (K) flows. The device of the present invention is particularly suited for connecting sections of pipes in a steam turbine (23).

The invention relates to a steam turbine system (1) comprising a steam turbine (2) which has a turbine housing and at least one turbine shaft (6, 7) accommodated in the turbine housing and sealed by means of seals (8) with respect to this steam turbine, a condenser (9) connected fluidically to the steam turbine (2), an evacuation unit (11) connected fluidically to the condenser (9), and a dry air source (17) which is connected fluidically to the steam turbine (2), wherein the steam turbine system (1) is designed in such a way that the evacuation unit (11) is optionally fluidically connectable to the dry air source (17). The invention further relates to a method for preserving components of a steam turbine system (1) to prevent idle-state corrosion, which comprises the steps: shutting down a steam turbine (2) of the steam turbine system (1) and sucking dry air into the steam turbine (2) using an evacuation unit (11) which additionally functions during intended operation of the steam turbine (2) to exhaust a resulting amount of gas into a condenser (9).

The invention relates to a bearing arrangement for bearing a bearing (2, 3) in a bearing housing (1), comprising a projection plate (12) that has a cylindrical projection (13) and a cut-out plate (15) which is arranged on the side of the projection plate (15) that has the projection (13) and in which a cylindrical cut-out (16) is provided, in which the projection (13) engages in a longitudinally displaceable manner, forming a projection clearance (18) between the projection circumference (14) and the cut-out circumference (17). A bearing housing support face (8) is formed on the bearing housing (1) and a bearing support face (9), which is parallel to the bearing housing support face (8), is formed on the bearing (2, 3), between which faces the fitting device (11) is arranged, wherein pressure is applied to the cut-out (16) by means of a hydraulic liquid (31), such that the hydraulic liquid (31) flows through the projection clearance (18) depending on the same, whereby the projection plate (12) is prestressed in a hydraulically damped manner against one of the support faces (8) and the cut-out plate (15) is prestressed in a hydraulically damped manner against the other support face (9).

The invention relates to an inner housing (3, 3a, 3b) for a flow machine, in particular for a steam turbine, wherein the inner housing (3, 3a, 3b) comprises a first part (3a) and a second part (3b), wherein a vertical joint (5) is formed between the first part (3a) and the second part (3b).
摘要:
A steam turbine has a two-shell housing, including an outer casing (1) and an inner casing (2) arranged therein, as well as a pipe (3) that extends through the outer casing (1) for supplying and/or removing steam to or from the inner casing (2), the pipe being provided with a pair of apertures (4, 5) arranged opposite each other on the inner casing (2). According to the invention, a first steam supply or discharge pipe (6) can be connected to a first aperture (4), and the second aperture (5) is closed by a cover (7).
