Embodiment Construction

[0022] The present invention will be further elaborated below in conjunction with embodiment.

[0023] In order to better describe the present invention, the operation and working process of the equipment of the present invention will be described below. First start the electronic switch to lift the pendulum of the oscillometric impact machine 4 to the designated position, and send the sample into the bath furnace 5; secondly, according to the needs of the test, the sample is heated or cooled through the bath furnace 5; The detector detects the temperature of the upper and lower surfaces of the sample. When the surface temperature of the sample reaches the requirement and the temperature control accuracy is kept within ±2°C for 20 minutes, the impact test can be started; the electronic switch is activated through the console, and the sample push plate pushes the sample along the guide rail. Move forward until it is in close contact with the centering device 6. When the sample ...

Using the invention, precision of temperature is about +-1deg.C, alignment error is less than 0.14mm; Time of sample from furnace to clashing is 2.7s.

Description

technical field [0001] The invention belongs to the field of automatic device for impact test after irradiation of samples, and in particular relates to an automatic device for impact test after irradiation of nuclear power plant pressure vessel steel with pile monitoring samples. Background technique [0002] The nuclear pressure vessel is an important part of the pressurized water reactor nuclear power plant. Because the embrittlement of the vessel steel is obvious after irradiation, the determination of its irradiation brittleness is an important subject related to the safety of nuclear power. The irradiation brittleness is mainly determined by the impact test, and the main equipment of the test is an oscillometric impact machine. The test procedure is as follows. Firstly, the standard sample is placed in the reactor for irradiation; then the irradiated sample is placed in the bath furnace for heating or cooling, and the heating or cooling temperature can be calibrated in...
