Embodiment 1

[0050] like figure 1 As shown, a static immersion test device for liquid lead and bismuth environment, the device includes a frame 1, a test kettle 3, the mouth of the test kettle 3 faces upward, and also includes a lifting device 2 and a bellows 8, and the bellows The upper end of the bellows 8 is connected to the frame 1, and the lower end of the bellows 8 is docked with the mouth of the kettle;

[0051] The output end of the lifting device 2 is connected with the test kettle 3, and the lifting device 2 is used to drive the test kettle 3 to move up and down to change the height of the test kettle 3 in space, and the test kettle 3 occurs the described During the lifting and lowering movement, the bellows 8 is compressed or stretched along with the movement of the test kettle 3 .

[0052] In the prior art, to complete the corrosion test of materials in a specific environment, it is generally sufficient to simulate the required corrosion environment. When conducting corrosion ...

Embodiment 2

[0066] like figure 1 As shown, the present embodiment is further limited on the basis of embodiment 1:

[0067] In order to make the lifting device 2 work, the bellows 8 only shrinks or is elongated, so as to avoid lateral interference when the corresponding sensor and the sample hanger 10 are installed vertically, it is set as follows: the bellows 8 , The axial direction of the test kettle 3 is located in the vertical direction, and under the action of the lifting device 2, the movement direction of the test kettle 3 is located in the vertical direction.

[0068] As mentioned above, this solution takes into account the environmental pollution problems caused by the experimental process. Further, it is set to: it also includes an inner cover 6 and a kettle cover 7. The inner cover 6 is arranged at the opening position of the upper end of the bellows 8. The inner cover 6 It is used to close the upper end of the bellows 8; the kettle cover 7 is arranged at the still mouth of th...

Embodiment 3

[0075] like figure 1 As shown, this embodiment provides a more detailed implementation on the basis of any one of the technical solutions provided in the above embodiments:

Abstract

The invention discloses a liquid lead-bismuth environment static soaking test device and test method. The device comprises a frame, a test kettle, a lifting device and a corrugated pipe, wherein the kettle opening of the test kettle is upward, the upper end of the corrugated pipe is connected with the frame, and the lower end of the corrugated pipe is in butt joint with the kettle opening; the output end of the lifting device is connected with the test kettle, the lifting device is used for driving the test kettle to do ascending and descending movement so as to change the height of the test kettle in the space, and when the test kettle does ascending and descending movement, the corrugated pipe is compressed or stretched along with the movement of the test kettle. The method is based on the device. With application of the device and the method, static soaking in the liquid lead-bismuth environment can be completed, and the device and the method have the characteristics of convenienceand safety in operation.

Description

technical field [0001] The invention relates to the technical field of corrosion tests, in particular to a liquid lead-bismuth environment static immersion test device and a test method. Background technique [0002] As a reactor coolant, liquid lead-bismuth alloy has high safety and reliability, but liquid lead-bismuth alloy has the problem of corrosion structure. In the specific application, the above corrosion problems determine its use has certain safety hazards. Therefore, selecting or designing suitable materials is one of the ways to solve the corrosion of liquid lead-bismuth alloys. [0003] In the field of nuclear power, relevant research institutions and enterprises have conducted related research on the corrosion characteristics of liquid lead-bismuth alloys. By simulating the corrosion behavior of materials in the environment of liquid lead-bismuth alloys outside the reactor, mastering the corrosion mechanism of materials is conducive to promoting Material selec...
