Method for carrying out a sound test of atleast one component and endoscope device used for the same
Patent number: 10302527Abstract: A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.Type: GrantFiled: March 3, 2017Date of Patent: May 28, 2019Assignee: Siemens AktiengesellschaftInventors: Henning Almstedt, Ralf Bell, Ulrich Beul, Kai Brune, Robin Burzan, Matthias Heue, Benedikt Hofmeister, Mario Koebe, Michael Löhr, Stefan Riemann, Andreas Schaarschmidt, Andreas Ulma, Sebastian Zahn, Gerta Zimmer -
Patent number: 10167742Abstract: A steam cycle for a power station, and to a method for operating, in particular for starting, a steam cycle. The steam cycle has a high-pressure turbine, a condenser and a steam generator. The steam generator is connected to the high-pressure turbine via a first line. Live steam quick-closing valves and live steam regulating valves for supplying the high-pressure turbine are arranged in the direction of the steam flow between the steam generator and the high-pressure turbine. A starting line is arranged downstream of the high-pressure turbine in the direction of the steam flow, the starting line connecting a waste steam region downstream of the high-pressure turbine with the condenser. At least one regulator regulates a closing of a starting valve for sealing the starting line, and an opening of the live steam valve, depending on the rotational speed, a temperature and load state of the high-pressure turbine.Type: GrantFiled: April 16, 2015Date of Patent: January 1, 2019Assignee: Siemens AktiengesellschaftInventors: Bernd Leu, Martin Ophey, Klaus Rothe, David Veltmann, Kai Brune, Matthias Heue, Rudolf Pötter, Michael Schütz
