20140348644 | ARRANGEMENT OF A SEGMENTED RETRACTABLE SEAL IN A STATOR OF A TURBINE - A segmented retractable seal is provided in a stator of a turbine by which a rotor seal is arranged radially and axially movably in a groove formed in the stator of the turbine and is connected with a mechanism which retracts it away from the rotor of the turbine in a radial direction. The groove formed in the stator of the turbine contains an outer partial groove formed on the inner surface of the stator and an inner partial groove formed in the body of the stator and connected with it, its width being smaller than or equal to that of the outer partial groove. A head of the seal is arranged in the inner partial groove, and a comb of the seal is arranged in the outer partial groove. The head of the seal and the comb of the seal are connected by a neck of the seal. | 11-27-2014 |

20140230555 | METHOD OF DETECTING AND LOCALIZING PARTIAL ROTOR-STATOR RUBBING DURING THE OPERATION OF A TURBINE - The rotor of the turbine is monitored by sensors of the rotor vibrations arranged in at least one plane of measuring perpendicular to the axis of the rotor and by sensors of the absolute vibrations of the bearings. When using this method of processing, synchronically digitalized signals of the sensors of rotor vibrations, first the arithmetic mean of the individual harmonic bands in full spectrum in the frequency domain is calculated, by which means the information about the subharmonic components and their multiples in the full spectrum of these signals is transferred into the frequency band −1X to 1X, at the same time is by the calculation of the median estimated the level of the signal noise, with which individual frequency bands of the full spectrum are encumbered, and which is subtracted from the amplitudes in the individual frequency bands of full spectrum of the signals of the sensors. | 08-21-2014 |
