| description | The invention belongs to the technical field of nuclear power, and particularly relates to a nuclear power station main pump mechanical seal repairing and test verification method. According to the nuclear power station main pump mechanical seal repairing and test verification method, repairing and test verification of an existing main pump with a radioactive old mechanical seal can be achieved, the size parameters and performance of the repaired mechanical seal reach the factory acceptance standard of new spare parts, the repaired mechanical seal serves as the spare parts to be applied to the site, the maintenance cost is greatly reduced, and radioactive waste is reduced; the problem of on-site spare part shortage caused by long purchase period of imported spare parts is solved. The method can be applied to repairing work of radioactive old mechanical seals of different types of main pumps of domestic nuclear power plants, the old seals are recycled after being repaired, and consumption of spare parts and ma |
