| Abstract | The research tells about diesel-generator installation as the most important element of nuclear power plant safety system. Scientific research institute "Nuclear Power Mechanical Engineering" of Volgodonsk Engineering Technical Institute of National Nuclear Center of Moscow State Engineering Physics Institute within the contract with the Smolensk Nuclear Power Plant developed the working program of diagnosing of the diesel generator 15D100. In article the basic provisions of this program concerning the vibroacoustic analysis are stated. When developing approaches to diagnosing authors consider normative documents, features of operation of the diesel-generator equipment in the conditions of the nuclear power plant, generalize experience of diagnosing of the similar equipment in the transport sphere. Diagnostics on indicators of vibration covers all rotating equipment (pumps) entering into group of diesel-generator installation. Much attention in the article is paid to a choice of installation sites of vibration sensors. As methods of diagnostic data processing the preference is given to the spectral and сepstral analysis, the peak-factor and trend characteristics also are used. It is offered to estimate a deviation of the actual corner of fuel injection, wear of sealing rings, increase in a gap in a piston joint on bending around a vibration signal. Methods offered by authors have to provide reliable diagnosing of the equipment, detection of defects at early stages of development, forecasting of the diesel generator condition. |
