摘要： A turbocharger, has a turbine for expanding a first medium and a compressor for compressing a second medium. The turbine includes a turbine housing and a turbine rotor. The compressor includes a compressor housing and a compressor rotor coupled to the turbine rotor via a shaft. A bearing housing is arranged between the compressor and turbine housings in which the shaft is mounted. The turbine and bearing housings are connected via a fastening device mounted on a flange of the turbine housing with a first section and a second section that covers a flange of the bearing housing at least in sections. The fastening device is contoured curved on a surface of the second section facing the flange of the bearing housing.

摘要： The invention relates to a method for producing a rotor of a flow engine, namely an integrally bladed rotor with an integral outer shroud, comprising at least the following steps: a rotor blank comprising the integral rotor blades and the integral outer shroud is first produced by means of a generative production method; the rotor blank is then subjected to a separating surface treatment at flow-guiding sections and is subjected, separately therefrom, to a machining surface treatment at non-flow-guiding sections.

The compressor (3) has a compressor housing (6) and a compressor rotor (7) that is coupled to the turbine rotor (5) via a shaft (8). The turbine housing (4) and the compressor housing (6) are each connected to a bearing housing (9) arranged there between, in which the shaft (8) is mounted. The turbine housing (4) has an inflow housing (11), a nozzle ring (15) with guide blades (16) and an insert piece (13). The nozzle ring (15) is centered and radially guided by a projection (17) on the bearing housing (9).

摘要： A method for operating a cooling system of a ship, having a sea water part system with a sea water pump (14a, 14b) and at least one first cooling water circuit. The first cooling water circuit includes a bypass in a heat exchanger coupling the sea water part system and the first cooling water circuit and a control valve. A position of the control valve determines a cooling water proportion of the first cooling water circuit that is conducted via the heat exchanger and a cooling water proportion of the first cooling water circuit that is conducted via the bypass. The position of the control valve is controlled such that an advance cooling water temperature corresponds to a set point value. The rotational speed of the sea water pump is controlled based on the position of the control valve.

摘要： Catalytic converter unit for an exhaust gas catalytic converter, in particular an SCR catalytic converter unit for an SCR catalytic converter of a marine diesel internal combustion engine, with multiple catalytic converter modules. Each catalytic converter module has a ceramic catalytic converter body through which exhaust gas flows and a metallic casing for the ceramic catalytic converter body. The respective ceramic catalytic converter body is received in the respective metallic casing and is surrounded in certain sections by the latter. The catalytic converter modules are positioned with first flowed-through ends on a support grating. A counter-brace is positioned at the opposite second flowed-through ends of the catalytic converter modules, and the catalytic converter modules are clamped between the support grating and the counter-brace.

摘要： A combustion chamber assembly of a gas turbine, for combusting a fuel in the presence of combustion air, is configured as a dual-fuel combustion chamber assembly. In a gas fuel operating mode a mixture of a gaseous fuel and combustion air is supplied to the combustion chamber via a swirl body. In a liquid fuel operating mode liquid fuel is fed to the combustion chamber via a fuel lance and combustion air is fed to the combustion chamber via the swirl body. The fuel lance is surrounded by an adjoining lance cap to form a radial clearance therebetween such that the combustion chamber is feedable with combustion air via the radial clearance, bypassing the swirl body.

摘要： A gas turbine with a compressor, in which air can be compressed; with at least one burner having a combustion chamber, which can be supplied with the compressed air and in which a fuel can be combusted in the presence of the compressed air subject to heating the air; a turbine, in which the heated air can be expanded; a diffuser arranged, seen in flow direction of the expanded air, downstream of the turbine; a plurality of temperature sensors, dependent on the measurement values of which a thermodynamic mean temperature or mixed-out turbine outlet temperature of the expanded air can be determined. The temperature sensors are arranged in the region of a diffuser cover, which at an outlet end of the diffuser closes off a hollow space of the diffuser positioned radially inside of a flow duct of the diffuser.

摘要： A gas exchange valve, with a valve stem carrying a valve body and a valve seat for the valve body. When closed, the valve body lies against the valve seat and when opened the valve body does not lie against the valve seat. A valve guide guides the valve stem. The valve guide has a radially inner groove that receives a separate wiping element for the valve stem.
