Description

Technical Field

[0001] The embodiments of the present application relate to the field of material performance testing, and more specifically, to an erosion-corrosion testing device and system. Background Art

[0002] In the field of nuclear power applications, the core materials (cladding, heat transfer tubes) used in its reactors are required to have good corrosion resistance. For example, in a nuclear energy system, a lead-bismuth eutectic (LBE) alloy is usually used as the coolant for the core materials. Therefore, the core materials are required to have excellent corrosion resistance to the LBE alloy. In view of this, before the actual application of the core materials, their corrosion resistance is often tested to ensure the absolute safety of the nuclear reactor.

[0003] Generally, the corrosion resistance of the core materials to be tested can be tested under various corrosion conditions. However, using this testing method will result in too low accuracy, too long time-consuming for the corrosion resistance test, and unable to accurately simulate the use effect of the corrosion-resistant materials under actual working conditions.

[0004] Therefore, how to reduce the time cost of the corrosion resistance test and improve the accuracy of the corrosion resistance test is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The embodiments of the present application provide an erosion-corrosion testing device and system, which can reduce the time cost of the corrosion resistance test and improve the accuracy of the corrosion resistance test.

[0006] In a first aspect, the embodiments of the present application provide an erosion-corrosion testing device, including:

[0007] A container and a container cover, where the container is used to hold a corrosion solution, and the container cover is used to seal the container;

[0008] A motor, which is fixed above the container cover;

[0009] A fixing member, the container cover is provided with a through hole penetrating the container cover, and the connecting rod of the motor suspends the fixing member in the container through the through hole. The fixing member is provided with at least one fixing structure for suspending the specimen to be tested.

[0010] In a second aspect, the embodiments of the present application provide an erosion-corrosion testing system, including:

[0011] The erosion-corrosion testing device described in the first aspect or its various implementation manners, and a first control device, where the first control device is used to drive the motor in the erosion-corrosion testing device.

[0012] In the embodiment of the present application, the fixing member is designed to be suspended in the container through the through hole of the container cover by means of the connecting rod of the motor, so that the test sample to be tested can be in contact with the corrosion solution during the test, while the fixing member is not in contact with the corrosion solution, which can improve the service life of the fixing member.

[0013] In addition, the fixing member driven by the motor can drive the test sample to be in a moving state in the corrosion solution, thereby constructing a test condition in which there is relative movement between the test sample and the corrosion solution. Equivalently, the corrosion resistance of the test sample under the scouring condition can be tested. Equivalently, the accuracy of the corrosion resistance test can be improved by simulating the use effect of the material under the actual working condition. In addition, the suspension design of the fixing member can avoid the interference of the fixing member to the corrosion solution, reduce the movement resistance of the fixing member, and increase the relative movement speed between the test sample and the corrosion solution. Equivalently, the time cost of the corrosion resistance test can be reduced by increasing the scouring amplitude. Therefore, the scouring corrosion test device provided by the embodiment of the present application can reduce the time cost of the corrosion resistance test and improve the accuracy of the corrosion resistance test.

[0021] Next, the technical solutions in the embodiments of the present application will be described with reference to the drawings in the embodiments of the present application.

[0022] It should be noted that for the convenience of description, in Figures 1 to 7In the illustrated embodiments, the same reference numerals denote the same components, and for the sake of brevity, in different embodiments, the detailed description of the same components is omitted.

[0023] Figure 1 is a schematic diagram of an erosion-corrosion test device 10 provided by an embodiment of the present application.

[0024] As Figure 1 shown, the erosion-corrosion test device 10 may include:

[0025] A container 110 and a container lid 120, the container 110 is used to hold a corrosion solution, and the container lid 120 is used to seal the container 110;

[0026] A motor 130, which is fixed above the container lid 120;

[0027] A fixing member 150, the container lid 120 is provided with a through hole penetrating the container lid 120, and a connecting rod 140 of the motor 130 suspends the fixing member 150 in the container 110 through the through hole. The fixing member 150 is provided with at least one fixing structure for suspending a specimen to be tested.

[0028] In an embodiment of the present application, the fixing member 150 is designed to be suspended in the container 110 through the through hole of the container lid 120 by the connecting rod 140 of the motor 130, so that the specimen to be tested can be in contact with the corrosion solution during the test, while the fixing member 150 is not in contact with the corrosion solution, which can improve the service life of the fixing member 150.

[0029] In addition, the fixing member 150 driven by the motor 130 can drive the specimen to be tested to be in a moving state in the corrosion solution, thereby constructing a test condition in which there is relative movement between the specimen to be tested and the corrosion solution. Equivalently, it realizes the test of the corrosion resistance of the specimen to be tested under erosion conditions. Equivalently, the accuracy of the corrosion resistance test can be improved by simulating the use effect of the material under actual working conditions. In addition, the suspension design of the fixing member 150 can avoid the interference of the fixing member 150 to the corrosion solution, reduce the movement resistance of the fixing member 150, and increase the relative movement speed between the specimen to be tested and the corrosion solution. Equivalently, the time cost of the corrosion resistance test can be reduced by increasing the erosion amplitude. It can be seen that the erosion-corrosion test device provided by the embodiment of the present application can reduce the time cost of the corrosion resistance test and improve the accuracy of the corrosion resistance test.

[0030] Exemplarily, the connecting rod 140 of the motor 130 or the fixing member 150 is provided with a telescopic structure, and the telescopic structure is used to adjust the contact area between the specimen to be tested and the corrosion solution. For example, the telescopic structure can be a spring telescopic structure or a snap-type telescopic structure.

[0031] Exemplarily, the container 110 may be a barrel-shaped structure or a structure of other shapes.

[0032] Exemplarily, the container lid 120 may be a plate-shaped structure.

[0033] Exemplarily, a cavity for accommodating a cooling medium may be provided inside the container lid 120. Optionally, the cavity of the container 120 may be provided with an outlet and an inlet. The outlet on the cavity of the container 120 may be used to form an output pipeline for the cooling medium, and the inlet on the cavity of the container 120 may be used to form an input pipeline for the cooling medium.

[0034] It should be understood that the present application does not specifically limit the sealing method between the container 110 and the container 120. For example, it may be sealed by a sealing strip, pressure sealing or vacuum sealing. Of course, it may also be sealed by other methods.

[0035] In some embodiments, the fixing member 150 is a plate-shaped structure, and the at least one fixing structure includes fixing structures provided at at least one radius with the center of the plate-shaped structure as the center of the circle.

[0036] In this embodiment, when the at least one radius is a plurality of radii, when the motor 130 drives the fixing member 150, the fixing structures at different radii can move at different linear speeds. Thus, the corrosion resistance performance can be tested under test conditions with various scouring amplitudes, which can not only save test time and reduce test costs, but also obtain diverse test results.

[0037] Exemplarily, the plate-shaped structure may be a plate-shaped structure with a regular shape. For example, the plate-shaped structure may be a plate-shaped structure with regularly distributed corners. For example, the plate-shaped structure may be a circular, elliptical, rectangular, oblong or wavy plate-shaped structure.

[0038] Exemplarily, the plate-shaped structure may be an irregular plate-shaped structure. For example, the plate-shaped structure may be a plate-shaped structure with irregularly distributed corners.

[0039] Figure 2 It is a schematic diagram of the fixing member 150 with a plate-shaped structure provided by an embodiment of the present application.

[0040] As Figure 2As shown, the fixing member 150 may be a circular plate-like structure. The connection position of the connecting rod 140 of the motor 130 and the fixing member 150 is the central position 151. Assuming that the fixing structure on the fixing member 150 is an opening 152 penetrating the fixing member 150, at this time, the at least one fixing structure includes a plurality of openings arranged at a radius of the length in 3 with the center of the plate-like structure as the center of the circle. Specifically, the at least one fixing structure may include 8 openings arranged at the minimum radius, 16 openings arranged at a radius that is the intermediate value between the minimum radius and the maximum radius, and 16 openings arranged at the maximum radius. Based on this, when the motor 130 drives the fixing member 150, the test specimens suspended on the 8 openings arranged at the minimum radius, the 16 openings arranged at a radius that is the intermediate value between the minimum radius and the maximum radius, and the 16 openings arranged at the maximum radius can move at the corresponding linear speeds. Thus, the corrosion resistance performance can be tested under the test conditions with 3 scouring amplitudes, which can not only save the test time and reduce the test cost, but also obtain diverse test results.

[0041] In some embodiments, the plane where the connection position of the connecting rod 140 of the motor 130 and the fixing member 150 is located is higher than the plane where the at least one fixing structure is located.

[0042] In this embodiment, designing the plane where the connection position of the connecting rod 140 of the motor 130 and the fixing member 150 is located to be higher than the plane where the at least one fixing structure is located can not only better suspend the specimens to be tested, but also, when the corrosive solution fluctuates up and down, can minimize the contact area between the fixing member 150 and the corrosive solution, thereby ensuring the service life of the fixing member 150.

[0043] Exemplarily, the middle part of the fixing member 150 bulges towards the opening of the container 110.

[0044] Exemplarily, the edge part of the fixing member 150 bulges towards the bottom of the container 110.

[0045] Exemplarily, the fixing member 155 may be an inverted dish-like structure.

[0046] In some embodiments, the edge position of the connection position of the connecting rod 140 of the motor 130 and the fixing member 150 bends and extends towards the bottom of the container 110 to form a first arc surface, and the end of the first arc surface extends towards the side wall of the container 110 to form a first plane, and the at least one fixing structure is arranged on the first plane.

[0047] In this embodiment, relative to the bottom of the container 110, since the first plane is lower than the first arc surface, setting the at least one fixing structure on the first plane can not only better hang the test sample, but also minimize the contact area between the fixing member 150 and the corrosive solution as much as possible when the corrosive solution fluctuates up and down, thereby ensuring the service life of the fixing member 150.

[0048] Exemplarily, when the fixing member 150 is a plate-like structure with a regular shape, the first plane is a plane with a regular shape. For example, when the plate-like structure is a plate-like structure with regularly distributed corners, the first plane is also a plane with regularly distributed corners. For example, when the plate-like structure is a circular, elliptical, rectangular, oblong or wavy plate-like structure, the first plane is a circular ring, elliptical ring, rectangular ring, oblong or wavy plane respectively.

[0049] Exemplarily, when the fixing member 150 is a plate-like structure with an irregular shape, the first plane is a plane with an irregular shape. For example, when the plate-like structure is a plate-like structure with irregularly distributed corners, the first plane is also a plane with irregularly distributed corners.

[0050] Exemplarily, when the fixing member 150 is a cap-shaped structure, the first plane is the plane where the brim of the cap-shaped structure is located.

[0051] Exemplarily, the fixing member 150 is an inverted dish-shaped structure.

[0052] Figure 3 It is a top view of the fixing member of the cap-shaped structure provided by the embodiment of the present application.

[0053] As Figure 3 shown, the fixing member 150 is a cap-shaped structure. Among them, the connection position between the connecting rod 140 of the motor 130 and the fixing member 150 is the central position 151. The edge position of the central position 151 bends and extends towards the bottom of the container 110 to form a first arc surface 153. The end of the first arc surface 153 extends towards the side wall of the container 110 to form a first plane 154. The at least one fixing structure is arranged on the first plane 154. For example, the fixing structure can be an opening 155 arranged on the first plane 154.

[0054] Figure 4 Is Figure 3 The side view of the fixing member shown along the A1-A2 direction.

[0055] As Figure 4As shown, in the side view along the A1-A2 direction, the connecting rod 140 of the motor 130 is connected to the central position 151 of the fixing member 150. Since the first plane 154 provided with the opening 155 is lower than the first arc surface 153, the at least one fixing structure is arranged on the first plane 154. This can not only better hang the sample to be tested, but also minimize the contact area between the fixing member 150 and the corrosion solution as much as possible when the corrosion solution fluctuates up and down, thereby ensuring the service life of the fixing member 150.

[0056] Of course, in other alternative embodiments, the first arc surface may also be an inclined plane inclined relative to the bottom of the container 110, and the embodiments of the present application do not make specific limitations thereto. For example, in a specific implementation manner, the edge position of the connection position of the connecting rod 140 of the motor 130 and the fixing member 150 extends towards the bottom of the container 110 at a preset angle to form a first inclined plane inclined relative to the bottom of the container 110. The end of the first hypotenuse extends towards the side wall of the container 110 to form a first plane, and the at least one fixing structure is arranged on the first plane. Optionally, the preset angle may be 45 degrees. In another specific implementation manner, the edge position of the connection position of the connecting rod 140 of the motor 130 and the fixing member 150 extends towards the side wall of the container 110 to form a wavy surface parallel to the bottom of the container 110, and a fixing structure may be formed at the peak position of the wavy surface close to the bottom of the container 110. Optionally, the wavy surface may include multiple peaks and at least one valley.

[0057] In some embodiments, at least one edge position of the connection position of the connecting rod 140 of the motor 130 and the fixing member 150 bends and extends towards the bottom of the container 110 to form at least one hanging rod. The end of each hanging rod in the at least one hanging rod extends towards the side wall of the container 110 to form a second plane, and the at least one fixing structure includes a fixing structure arranged on the second plane.

[0058] In this embodiment, relative to the bottom of the container 110, since the second plane is the lowest surface of the fixing member 150, arranging the fixing structure on the second plane can not only better hang the sample to be tested, but also minimize the contact area between the fixing member 150 and the corrosion solution as much as possible when the corrosion solution fluctuates up and down, thereby ensuring the service life of the fixing member 150.

[0059] Exemplarily, the at least one hanging rod may be multiple hanging rods. Optionally, the multiple hanging rods may be symmetrically distributed hanging rods to increase the stability of the multiple hanging rods.

[0060] Exemplarily, the at least one hanging rod may be an arc-shaped hanging rod.

[0061] Exemplarily, the structure formed by the at least one suspension rod is a cross structure or an umbrella structure.

[0062] Exemplarily, when the structure formed by the at least one suspension rod is a cross structure, the fixing member 150 is the intersection point of the cross structure.

[0063] Exemplarily, when the structure formed by the at least one suspension rod is an umbrella structure, the fixing member 150 can be the top position of the umbrella structure, and the at least one suspension rod can be the umbrella ribs for supporting the umbrella cloth of the umbrella structure.

[0064] Exemplarily, the connection position between the connecting rod 140 of the motor 130 and the fixing member 150 is the central position of the fixing member 150.

[0065] Exemplarily, a protrusion is formed by extending from the central position of the fixing member 150 towards the opening of the container 110, and this protrusion serves as the connection position between the connecting rod 140 of the motor 130 and the fixing member 150.

[0066] Exemplarily, a groove is formed by extending from the central position of the fixing member 150 towards the opening of the container 110, and this groove serves as the connection position between the connecting rod 140 of the motor 130 and the fixing member 150.

[0067] Figure 5 It is a top view of the fixing member of the cross structure provided by the embodiment of the present application.

[0068] As Figure 5 shown, the fixing member 150 is a cross structure. Among them, the connection position between the connecting rod 140 of the motor 130 and the fixing member 150 is the central position 151. At least one edge position of the central position 151 bends and extends towards the bottom of the container 110 to form at least one suspension rod 156. The end of each suspension rod 156 in the at least one suspension rod 156 extends towards the side wall of the container 110 to form a second plane 157. The at least one fixing structure includes a fixing structure provided on the second plane 157. For example, the fixing structure can be an opening 158 provided on the second plane 157.

[0069] Figure 6 Is Figure 5 The side view of the fixing member shown along the B1 - B2 direction.

[0070] As Figure 6As shown, in the side view along the B1-B2 direction, the connecting rod 140 of the motor 130 is connected to the central position 151 of the fixing member 150. Since the second plane 157 is the lowest surface of the fixing member 150, a fixing structure is provided on the second plane 157. This can not only better suspend the test sample, but also minimize the contact area between the fixing member 150 and the corrosion solution as much as possible when the corrosion solution fluctuates up and down, thereby ensuring the service life of the fixing member 150.

[0071] Of course, in other alternative embodiments, the at least one suspension rod may also be a suspension rod with a shape other than an arc, and the embodiments of the present application do not specifically limit this. For example, as a specific implementation, at least one edge position of the connection position between the connecting rod 140 of the motor 130 and the fixing member 150 may extend along a preset angle towards the bottom of the container 110 to form at least one suspension rod. The end of each suspension rod in the at least one suspension rod extends towards the side wall of the container 110 to form a second plane, and the at least one fixing structure includes a fixing structure provided on the second plane. That is to say, the at least one suspension rod may be two straight rods connected at different angles. In another specific implementation, at least one edge position of the connection position between the connecting rod 140 of the motor 130 and the fixing member 150 may extend towards the side wall of the container 110 to form at least one hanging rod in a wavy shape parallel to the bottom of the container 110. A fixing structure may be formed at the peak position of each hanging rod close to the bottom of the container 110. Optionally, each hanging rod may include multiple peaks and at least one valley.

[0072] In some embodiments, the fixing structure is a receiving hole penetrating the fixing member 150; the erosion corrosion test device 10 further includes: a mounting member for fixing the first end of the test sample above the receiving hole, and the second end of the test sample passes through the receiving hole and hangs below the receiving hole.

[0073] Exemplarily, the first end is provided with an external thread, and the mounting member is a nut that mates with the external thread of the first end.

[0074] Exemplarily, the diameter of the first end is equal to the diameter of the second end, the first end is provided with an external thread, and the mounting member is a nut that matches the external thread of the first end.

[0075] Exemplarily, the diameter of the first end is greater than the diameter of the receiving hole.

[0076] Exemplarily, the length of the second end is greater than or equal to the thickness of the fixing member 150 to ensure that the second end can pass through the receiving hole and expose a part.

[0077] Exemplarily, a groove or a protrusion is formed around the accommodation hole and extends towards the bottom of the container 110. The groove or the protrusion can be used to identify the position of the accommodation hole.

[0078] In some embodiments, the fixing structure is a mounting hole passing through the fixing member 150. The mounting hole is provided with internal threads, and the first end of the specimen to be tested is connected to the internal threads in the mounting hole through external threads, and the second end of the specimen to be tested is suspended below the mounting hole.

[0079] Exemplarily, the length of the second end is less than or equal to the thickness of the fixing member 150 to ensure material saving of the specimen to be tested.

[0080] Exemplarily, a groove or a protrusion is formed around the mounting hole and extends towards the bottom of the container 110. The groove or the protrusion can be used to identify the position of the mounting hole.

[0081] In some embodiments, the erosion-corrosion test device further includes:

[0082] A magnetron device, which is arranged around or at the bottom of the container 110. The magnetron device includes a component for generating a magnetic field covering the corrosive solution.

[0083] Exemplarily, the magnetron device is used to drive the magnetically driven body to move in a direction opposite to the rotation of the fixing member 150 driven by the motor 130. Since the movement of the magnetically driven body can drive the corrosive liquid to move together with the magnetically driven body, a movement trajectory opposite to that of the fixing member can be generated, so that the two have a greater relative speed.

[0084] In some embodiments, a fixed track is provided at the bottom of the container 110, and the magnetron device is used to drive the magnetically driven body to move along the fixed track. This way of fixing the magnetically driven body on the fixed track can prevent the magnetically driven body from moving up and down in the corrosive liquid, thereby causing damage to the test specimen.

[0085] In some embodiments, the surface of the magnetically driven body has a baffle structure. For example, a baffle structure is provided on the side of the magnetically driven body facing the corrosive solution. This baffle structure can enable the magnetically driven body to generate a greater driving force for the movement of the corrosive liquid, thereby driving the corrosive liquid to move in the same direction as the magnetically driven body.

[0086] It should be understood that the magnetically driven body in the embodiments of the present application is a magnetic member. By controlling the direction of the magnetic field of the magnetron device, this member can be made to move in a specific direction. When the magnetron device generates a circular magnetic field at the bottom of the container, the magnetically driven body can perform a circular motion in this functional circular magnetic field, thereby driving the movement of the corrosive metal liquid.

[0087] It should also be understood that in the embodiments of the present application, the number of magnetic drivers may include multiple, so as to more effectively drive the movement of the corrosive liquid.

[0088] Exemplarily, the component for generating the magnetic field covering the corrosion solution may be a magnetron coil.

[0089] Exemplarily, the magnetron device further includes a component for controlling the magnetic field intensity of the magnetic field.

[0090] Exemplarily, the corrosion solution is a liquid metal corrosion solution.

[0091] In the embodiments of the present application, when the corrosion solution is a metal corrosion solution, the magnetron device can drive the metal corrosion solution to move in a direction opposite to the direction in which the motor 130 drives the fixing member 150 to rotate, which can increase the relative movement speed between the specimen to be tested and the corrosion solution, and improve the test efficiency and the true erosion speed.

[0092] In some embodiments, the container 110 is provided with an air outlet for discharging the corrosive gas vaporized from the corrosive solution in the container 110 and the gas generated during the erosion corrosion process. The gas generated during the erosion corrosion process may be harmful gases and impurity gases generated during the mutual movement and reaction of the corrosive solution and the specimen to be tested.

[0093] Exemplarily, the outward extension of the air outlet can be used to form an air outlet channel or an air outlet pipe.

[0094] In some embodiments, the container 110 is provided with an air inlet for inputting inert gas into the container 110.

[0095] Exemplarily, the air inlet can extend outward to form an air inlet channel or an air inlet pipe

[0096] Exemplarily, when the cavity is only provided with the air outlet, the air outlet can be an outlet for vacuum pumping.

[0097] Exemplarily, when the cavity is provided with the air outlet and the air inlet, the air outlet can be an outlet for pumping air in the cavity, and the air inlet can be an inlet for inputting inert gas.

[0098] It should be noted that other gases may also be mixed in the inert gas, such as oxygen, argon or hydrogen, etc., and the present application does not make specific limitations on this.

[0099] Exemplarily, when the cavity is provided with the air outlet and the air inlet, the air inlet can be separately provided with a valve for controlling the switch. When both the air inlet and the air outlet are in the closed state, the container 110 is in a sealed state.

[0100] In some embodiments, the erosion-corrosion test device further comprises:

[0101] a heating device disposed at the bottom of the container 110.

[0102] Figure 7 is a schematic block diagram of an erosion-corrosion test system provided by an embodiment of the present application.

[0103] As Figure 7 shown, the erosion-corrosion test system 20 may include:

[0104] an erosion-corrosion test device 10; and

[0105] a first control device 21 for driving a motor in the erosion-corrosion test device 10.

[0106] In some embodiments, the erosion-corrosion test system 20 further comprises:

[0107] a second control device 22 connected to an air outlet and / or an air inlet of a container in the erosion-corrosion test device, the second control device 22 being configured to control the vacuum degree or the concentration of an inert gas in the container.

[0108] It should be noted that other gases may be mixed in the inert gas, such as oxygen, argon, or hydrogen. Correspondingly, the second control device 22 may be configured to control the vacuum degree in the container, or the second control device 22 may be configured to control the concentration of an input gas in the container, where the concentration of the input gas is the sum of the concentration of the inert gas and the concentration of other gases mixed in the inert gas.

[0109] In some embodiments, the erosion-corrosion test system 20 further comprises:

[0110] a cooling device 23 for cooling devices in the erosion-corrosion test device 10.

[0111] It should be understood that the specific types of the test specimens and the specific types of the corrosion solutions are not limited in the embodiments of the present application. For example, in the field of nuclear power applications, the test material to be tested may be the core material used in a reactor, and the corrosion material may be any one of materials such as a lead-bismuth eutectic (LBE) alloy for testing the corrosion resistance of the core material.

[0112] It should also be understood that in the description of the embodiments of the present application, the orientation or positional relationship indicated by terms such as "upper", "lower", "vertical", "horizontal", "top", "bottom", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In addition, unless otherwise clearly specified and defined, terms such as "installed", "connected", "connected to", "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or integrated; it can be a mechanical connection, an electrical connection or communicable with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.
