At the certain parameters growth of cracks under normal conditions operation begins. Growth rate of cracks depends on characteristics of metal of a rotor and the environment of cooling. By the example of turbogenerator ТГВ-3002 it is shown, that maximum permissible time of his operation after an abnormal mode should not exceed 4000 hours, and the careful control of a condition of a material of a rotor is necessary for maintenance of his further operation. |
