Abstract

The invention belongs to the technical field of nuclear power plant mechanical fabrication, and particularly relates to a test bed detecting reliability of a stud tensioner and a detection method thereof. The test bed includes a plurality of loop I top cap stud assemblies, a plurality of loop II top cap stud assemblies, a bed plate, a plurality of support rods, a plurality of lifting lugs, and a plurality of roller assemblies and support foot assemblies. The support rods are fixedly connected the lower surface of the bed plate, a plurality of threaded through holes are evenly formed in the upper surface of the bed plate, each support rod is provided with a roller assembly and a support foot assembly, the roller assemblies are fixedly connected with the support foot assemblies, the loop I top cap stud assemblies and the loop II top cap stud assemblies are fixed to the bed plate in a large and small ring-shaped arrangement mode with the center of the circle of the bed plate acting as anaxis.

Description

technical field [0001] The invention belongs to the technical field of mechanical assembly of nuclear power plants, and in particular relates to a test bench for testing the reliability of a bolt tensioning machine and a testing method thereof. Background technique [0002] As one of the main equipment of the primary circuit system of a nuclear power plant, the steam generator is mainly used as a heat transfer device to transfer the heat of the primary circuit to the feed water of the secondary circuit, so that it can generate saturated steam for driving the turbogenerator; and As part of the pressure boundary of the primary circuit, it bears the pressure of the coolant of the primary circuit, and forms a barrier with other pressure boundaries of the primary circuit to prevent the release of radioactive fission products of the core to the secondary circuit or the containment. The steam generators of Units 1 to 4 of a nuclear power plant are horizontal steam generators. An im...
