Description

Technical Field

[0001] The embodiments of this application relate to the field of testing pump devices, specifically to a testing system and method for testing high-temperature metal electromagnetic pumps. Background Technology

[0002] The statements herein are provided merely as background information in connection with this application and do not necessarily constitute prior art.

[0003] High-temperature metal electromagnetic pumps utilize the interaction between a magnetic field and an induced current in liquid metal to generate a magnetic force, which in turn causes the liquid metal to be subjected to an electromagnetic force, creating a pressure gradient that propels the liquid metal. To verify whether the performance of high-temperature metal electromagnetic pumps meets the requirements, it is necessary to test its flow rate, head, and other performance characteristics. However, existing testing systems for high-temperature metal electromagnetic pump performance testing still have many problems, making it difficult to guarantee the safety of the testing process and the accuracy and validity of the test results. Summary of the Invention

[0004] A brief overview of this application is provided below to offer a basic understanding of certain aspects thereof. It should be understood that this overview is not an exhaustive summary of the application. It is not intended to identify key or essential parts of the application, nor is it intended to limit its scope. Its purpose is merely to present certain concepts in a simplified form as a prelude to the more detailed description that follows.

[0005] In a first aspect, embodiments of this application provide a testing system for testing a high-temperature metal electromagnetic pump. The high-temperature metal electromagnetic pump is used to transport high-temperature liquid metal, the vapor of which is toxic. The testing system includes: a melting container configured to contain metal and convert it into liquid metal, the liquid metal being held within the melting container and circulating within the testing system during the test, and configured to determine the weight of the liquid metal contained therein; a replenishment container configured to contain metal and convert it into liquid metal, the liquid metal being held within the replenishment container; and a weighing container configured to contain liquid metal flowing from the melting container into the weighing container, and configured to determine the weight of the liquid metal contained therein. The high-temperature metal electromagnetic pump under test is used to provide power for the liquid metal to flow from the melting container into the weighing container, and to provide power for the liquid metal to flow back from the weighing container to the melting container or back to the replenishment container. The replenishment container is used to supply liquid metal to the high-temperature metal electromagnetic pump under test before the test begins.

[0006] Secondly, embodiments of this application provide a method for testing a high-temperature metal electromagnetic pump, wherein the high-temperature metal electromagnetic pump is tested using the testing system of any embodiment of the first aspect of this application.

[0007] The testing system in the embodiments of this application provides an initial circulating medium for the high-temperature metal electromagnetic pump under test by setting up a replenishment container. This eliminates the need for replenishing the pump with liquid through an external mechanism, avoiding affecting the sealing reliability of the testing system, reducing the risk of vapor leakage of liquid metal within the system, and improving the safety of the testing system. Furthermore, by comparing the weight of the liquid metal in the melting container and the weighing container, the weight of liquid metal flowing through the high-temperature metal electromagnetic pump per unit time can be obtained, thereby realizing the measurement of the flow rate of the high-temperature metal electromagnetic pump and improving measurement accuracy.

[0017] Exemplary embodiments of this application will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of actual implementations are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the content of this application.

[0018] It should also be noted that, in order to avoid obscuring this application with unnecessary details, only the equipment structure and / or processing steps closely related to the solution according to this application are shown in the accompanying drawings, while other details that are not closely related to this application are omitted.

[0019] Because high-temperature metal electromagnetic pumps can only apply force to liquid metal when their interior is filled with liquid metal, and cannot operate when there is no liquid metal inside, the existing technology of supplying liquid metal to the high-temperature metal electromagnetic pump through an external mechanism is prone to damaging the sealing of the test system, resulting in a safety risk of metal vapor leakage during the test. At present, there is no test system for testing high-temperature metal electromagnetic pumps that can fill the pump with liquid metal medium before the test begins without affecting the sealing reliability of the system.

[0020] Based on this, embodiments of this application provide a testing system for testing high-temperature metal electromagnetic pumps. The high-temperature metal electromagnetic pump is used to transport high-temperature liquid metal, the vapor of which is toxic. Figure 1 As shown, Figure 1The diagram shows a structural schematic of a test system for testing a high-temperature metal electromagnetic pump according to an embodiment of this application. The test system includes a melting container 100, a replenishment container 200, and a weighing container 300. A melting container 100 is configured to contain metal and convert it into liquid metal, the liquid metal being held within the melting container 100 and circulating within the testing system during the test, and is configured to determine the weight of the liquid metal it contains; a replenishment container 200 is configured to contain metal and convert it into liquid metal, the liquid metal being held within the replenishment container 200; a weighing container 300 is configured to contain liquid metal flowing from the melting container 100 into the weighing container 300, and is configured to determine the weight of the liquid metal it contains; wherein, a high-temperature metal electromagnetic pump 400 to be tested is used to provide power for the liquid metal to flow from the melting container 100 into the weighing container 300, and to provide power for the liquid metal to flow back from the weighing container 300 to the melting container 100 or back to the replenishment container 200, and the replenishment container 200 is used to supply liquid metal to the high-temperature metal electromagnetic pump 400 to be tested before the test begins.

[0021] The testing system provided in the embodiments of this application, by setting up a replenishment container 200 for containing metal and converting it into liquid metal, provides liquid metal to the high-temperature metal electromagnetic pump 400 under test before the test begins, thus providing an initial circulation medium for the high-temperature metal electromagnetic pump 400 under test. This eliminates the need for replenishing the pump through an external mechanism, avoiding impact on the sealing reliability of the testing system, reducing the risk of toxic liquid metal vapor leakage from the system, and improving the safety of the testing system. Furthermore, by setting the melting container 100 to determine the weight of the liquid metal it contains, and setting the weighing container 300 to determine the weight of the liquid metal flowing into the melting container 100, the weight of the liquid metal flowing through the high-temperature metal electromagnetic pump 400 per unit time can be obtained by comparing the weights of the liquid metal in the melting container 100 and the weighing container 300. This allows for the measurement of the flow rate of the high-temperature metal electromagnetic pump 400, which is beneficial for improving measurement accuracy.

[0022] In some embodiments, the replenishment container 200 is set at a height higher than the high-temperature metal electromagnetic pump 400 and the melting container 100. Before the test begins, the liquid metal in the replenishment container 200 is used to make the liquid metal enter the high-temperature metal electromagnetic pump 400 by gravity. There is no need to set up an additional power mechanism and pipeline to provide power for the delivery of liquid metal, so as to simplify the structure of the test system, further ensure the sealing reliability of the test system, and avoid the vapor overflow of liquid metal in the system.

[0023] In some embodiments, the melting container 100 includes a melting body 110, a check valve 120, a first weighing element 130, a first temperature measuring element 140, and a first heating element 150. The melting body 110 has a cavity for containing the metal and the molten liquid metal. A first heating element 150 is disposed in the melting body 110 to heat the metal and turn it into liquid metal, and to heat the melting body 110 to the test temperature during the test. A first temperature measuring element 140 is disposed in the melting body 110 to monitor the temperature of the melting body 110. A first weighing element 130 is disposed at the bottom of the melting body 110 to determine the weight of the liquid metal contained in the melting body 110. A check valve 120 is disposed in the melting body 110. Since the height of the replenishment container 200 is higher than that of the high-temperature metal electromagnetic pump 400 and the melting container 100, when the replenishment container 200 inputs liquid metal to the high-temperature metal electromagnetic pump 400 by gravity, the liquid metal may also flow into the melting body 110. Therefore, by setting the check valve 120, the liquid metal in the replenishment container 200 is prevented from flowing into the melting body 110.

[0024] The first temperature measuring element 140 can be configured for non-contact measurement. For example, it can be attached to the outer wall of the melting body 110 to avoid direct contact with the liquid metal, which would affect the measurement accuracy of the first temperature measuring element 140 during long-term operation.

[0025] In some embodiments, the weighing container 300 is higher than the melting container 100. By setting a height difference between the weighing container 300 and the melting container 100, the power performance of the high-temperature metal electromagnetic pump 400 in pumping liquid metal in the melting container 100 to the weighing container 300 can be tested. This facilitates the acquisition of effective test data, thereby accurately assessing the performance of the high-temperature metal electromagnetic pump 400. Furthermore, after the test is completed, the height difference can be used to drive the liquid metal in the weighing container 300 back to the melting container 100, reducing the power consumption of the high-temperature metal electromagnetic pump 400.

[0026] In some embodiments, a first control valve 610 is provided between the replenishment container 200 and the high-temperature metal electromagnetic pump 400 to allow the flow path between the replenishment container 200 and the high-temperature metal electromagnetic pump 400 to be open or closed. Thus, by opening and closing the first control valve 610, it is convenient to control the replenishment of liquid metal from the replenishment container 200 to the high-temperature metal electromagnetic pump 400, and the flow of liquid metal from the weighing container 300 back to the replenishment container 200 via the high-temperature metal electromagnetic pump 400.

[0027] In some embodiments, the replenishment container 200 includes a replenishment body 210, a second temperature measuring element 220, and a second heating element 230. The replenishment body 210 has a cavity for containing metal and molten liquid metal, and the replenishment body 210 supplies liquid metal to the high-temperature metal electromagnetic pump 400 to be tested; the second heating element 230 is disposed in the replenishment body 210 for heating the metal to turn it into liquid metal, and heating the replenishment body 210 to reach the test temperature during the test; the second temperature measuring element 220 is disposed in the replenishment body 210 for monitoring the temperature of the replenishment body 210.

[0028] The second temperature measuring element 220 can be configured for non-contact measurement. For example, it can be attached to the outer wall of the liquid replenishment body 210 to avoid direct contact with the liquid metal, which would affect the measurement accuracy of the second temperature measuring element 220 during long-term operation.

[0029] In some embodiments, a second control valve 620 is provided between the melting container 100 and the high-temperature metal electromagnetic pump 400 to allow the flow path between the melting container 100 and the high-temperature metal electromagnetic pump 400 to be open or closed. Thus, by opening and closing the second control valve 620, it is convenient to control the flow of liquid metal from the melting container 100 to the weighing container 300 via the high-temperature metal electromagnetic pump 400, and the flow of liquid metal from the weighing container 300 back to the melting container 100 via the high-temperature metal electromagnetic pump 400.

[0030] In some embodiments, a third control valve 630 is provided between the weighing container 300 and the high-temperature metal electromagnetic pump 400 to allow the flow path between the weighing container 300 and the high-temperature metal electromagnetic pump 400 to be open or closed. Thus, by controlling the opening and closing of the third control valve 630, it is convenient to control the flow of liquid metal from the melting container 100 to the weighing container 300 via the high-temperature metal electromagnetic pump 400, and the flow of liquid metal from the weighing container 300 back to the melting container 100 and the replenishment container 200 via the high-temperature metal electromagnetic pump 400.

[0031] In some embodiments, a regulating valve 640 is provided between the weighing container 300 and the high-temperature metal electromagnetic pump 400, so as to achieve precise control of the liquid metal flow rate and head by adjusting the opening of the regulating valve 640, thereby improving the effectiveness of the test data and facilitating accurate understanding of the performance of the high-temperature metal electromagnetic pump 400.

[0032] In some embodiments, the weighing container 300 includes a weighing body 310, a second weighing element 320, a third temperature measuring element 330, and a third heating element 340. The weighing body 310 has a cavity for containing liquid metal flowing from the melting container 100 into the weighing body 310; the third heating element 340 is disposed in the weighing body 310 for heating the weighing body 310 to the test temperature during the test; the third temperature measuring element 330 is disposed in the weighing body 310 for monitoring the temperature of the weighing body 310; and the second weighing element 320 is disposed at the bottom of the weighing body 310 for determining the weight of the liquid metal contained in the weighing body 310.

[0033] In some embodiments, the testing system further includes a liquid level measuring element 500, which is configured to measure the liquid level of the replenishment container 200. When the liquid level of the replenishment container 200 is lower than a predetermined value, the liquid metal in the weighing container 300 is pumped into the replenishment container 200 by the high-temperature metal electromagnetic pump 400. This avoids insufficient liquid metal in the replenishment container 200 to replenish the high-temperature metal electromagnetic pump 400, which would cause the high-temperature metal electromagnetic pump 400 to malfunction and affect the testing process.

[0034] Specifically, when the liquid level measuring device 500 detects that the liquid level in the replenishment container 200 is lower than a predetermined value, the second control valve 620 is closed, and the first control valve 610 and the third control valve 630 are opened. The high-temperature metal electromagnetic pump 400 provides power to pump the liquid metal in the weighing container 300 into the replenishment container 200.

[0035] In some embodiments, the liquid level measuring element 500 can be configured for non-contact measurement, for example, by using radar or ultrasonic methods to measure the liquid level of the replenishment container 200, so as to avoid direct contact with the liquid metal, which would affect the measurement accuracy during long-term operation.

[0036] In some embodiments, the testing system further includes a heating element that heats the pipeline between the melting container 100, the replenishment container 200, the weighing container 300, and the high-temperature metal electromagnetic pump 400 to preheat the pipeline before the test begins, so that the pipeline reaches the temperature required for the test, and during the test, the pipeline temperature is maintained at the temperature required for the test, ensuring the stable operation of the testing system.

[0037] Specifically, the heating element can be a heating wire, which is wound around the pipeline between the melting container 100, the replenishment container 200, the weighing container 300 and the high-temperature metal electromagnetic pump 400, so as to uniformly heat the pipeline.

[0038] Embodiments of this application also provide a method for testing a high-temperature metal electromagnetic pump, wherein the method uses the testing system of any embodiment of the first aspect of this application to test the high-temperature metal electromagnetic pump.

[0039] In some embodiments, the testing method includes the following steps:

[0040] S10: Vacuum the test system.

[0041] S20: Argon gas is introduced into the pipeline to make the pipeline argon-filled.

[0042] S30: Close the first control valve 610, heat the melting container 100, the replenishment container 200 and the weighing container 300 to the predetermined temperature, and preheat the high-temperature metal electromagnetic pump 400 to be tested.

[0043] S40: Close the third control valve 630, open the first control valve 610, and the replenishment container 200 supplies liquid metal to the high-temperature metal electromagnetic pump 400 to be tested.

[0044] S50: Start the high-temperature metal electromagnetic pump 400, close the first control valve 610, and adjust the opening of the regulating valve 640 so that the head of the high-temperature metal electromagnetic pump 400 reaches the rated head.

[0045] S60: The high-temperature metal electromagnetic pump 400 is used to provide power to make liquid metal flow from the melting container 100 into the weighing container 300. During this process, test data such as flow rate and head are collected to test the high-temperature metal electromagnetic pump 400.

[0046] S70: After the test is completed, turn off the high-temperature metal electromagnetic pump 400 and open the third control valve 630. Use the high-temperature metal electromagnetic pump 400 to provide power to make the liquid metal flow from the weighing container 300 back to the melting container 100, in preparation for the next test.

[0047] Specifically, in step S30, the melting body 110, the replenishing body 210, and the weighing body 310 are heated to a predetermined temperature by the first heating element 150, the second heating element 230, and the third heating element 340, respectively.

[0048] In some embodiments, the high-temperature metal electromagnetic pump 400 can be a high-temperature liquid metal electromagnetic pump, capable of conveying high-temperature liquid metal, such as... Figure 2 As shown, Figure 2A schematic diagram of the structure of a high-temperature liquid metal electromagnetic pump according to an embodiment of this application is shown. It includes: a main body 10, an inductor 20, a temperature sensor 30, and an excitation controller 40. The main body 10 is configured to be sealed to a conveyor for transporting high-temperature liquid metal; the inductor 20 is configured to induce a current in the high-temperature liquid metal within the main body 10, thereby creating a pressure difference at different positions of the high-temperature liquid metal within the main body 10, allowing the high-temperature liquid metal to flow at different positions; the temperature sensor 30 is configured to monitor the temperature within the main body 10 and heat the liquid metal based on the monitoring results; the excitation controller 40 is configured to adjust the power supply voltage and frequency of the inductor 20; wherein, the main body 10 is configured to prevent heat transfer from the high-temperature liquid metal to the inductor 20.

[0049] In this embodiment, the high-temperature liquid metal electromagnetic pump achieves sealing by sealing the main body 10 with the conveying component for transporting the high-temperature liquid metal, thus meeting the sealing requirements for high-temperature liquid metal transport and ensuring that the electromagnetic pump remains structurally safe and leak-free under various operating conditions. The sensor 20 is configured to induce a current in the high-temperature liquid metal within the main body 10, creating a pressure difference at different locations within the main body 10. The excitation controller 40 is configured to adjust the power supply voltage and frequency of the sensor 20, thereby adjusting the magnitude of the induced current generated by the sensor 20 within the high-temperature liquid metal within the main body 10. This, in turn, regulates the traveling wave electromagnetic force of the high-temperature liquid metal, enabling flow control and facilitating the controllable transport of high-temperature liquid metal in the molten salt electrolysis dry process. Furthermore, by configuring the main body 10 to prevent heat transfer from the high-temperature liquid metal to the sensor 20, the electromagnetic pump is prevented from failing, improving its operational stability and reliability.

[0050] In some embodiments, the conveying component for conveying high-temperature liquid metal, which is sealed to the body 10, may be, for example, a pipeline for conveying high-temperature liquid metal in a molten salt electrolysis dry process. In some embodiments, the body 10 is configured to be sealed and welded to the conveying component for conveying high-temperature liquid metal to ensure sealing strength and meet the conveying requirements of high-temperature liquid metal in a molten salt electrolysis dry process.

[0051] like Figure 2 As shown, in some embodiments, the excitation controller 40 supplies power to the sensor 20 through the cable 41, causing the sensor 20 to generate a traveling wave magnetic field, which in turn generates an induced current in the high-temperature liquid molten salt inside the body 10. The interaction between the induced current and the traveling wave magnetic field causes the high-temperature liquid metal to run in the direction of the traveling wave, and generates a pressure difference at different positions of the body 10, so that the high-temperature liquid metal can flow at different positions.

[0052] like Figure 3 As shown, Figure 3This is a structural schematic diagram showing the assembled state of the main body 10 and the sensor 20 of the high-temperature liquid metal electromagnetic pump according to an embodiment of this application. In some embodiments, the main body 10 includes a heat insulation member 11, a pump channel assembly 12, and a support assembly 13. The pump channel assembly 12 is configured to be sealed to the conveying member, and the high-temperature liquid metal flows in the pump channel assembly 12. The sensor 20 is configured to induce a current in the high-temperature liquid metal in the pump channel assembly 12. The support assembly 13 is configured to support the sensor 20 and the pump channel assembly 12. The heat insulation member 11 is configured to prevent the high-temperature liquid metal from transferring heat to the sensor 20 and is disposed on the pump channel assembly 12.

[0053] In this embodiment, high-temperature liquid metal flows in the pump channel assembly 12, which is sealed to the conveying component. The support assembly 13 is configured to support the sensor 20 and the pump channel assembly 12, so that the sensor 20 induces a current in the high-temperature liquid metal in the pump channel assembly 12, thereby creating a pressure difference at different positions of the high-temperature liquid metal and allowing it to flow at different positions. Furthermore, by configuring the heat insulation component 11 to prevent heat transfer from the high-temperature liquid metal to the sensor 20 and configuring it in the pump channel assembly 12, the heat transferred from the high-temperature liquid metal in the pump channel to the sensor 20 is reduced, thereby preventing the high-temperature liquid metal electromagnetic pump from failing and improving the operational stability and reliability of the electromagnetic pump.

[0054] In some embodiments, the thermal insulation element 11 can be made of nano-aerogel insulation felt with low thermal conductivity. Due to its extremely low thermal conductivity, good thermal stability, non-toxicity, environmental friendliness, high heat resistance (≥550℃), long lifespan, and non-flammability, its placement in the pump trench assembly 12 can effectively improve thermal insulation performance and further prevent heat transfer from the high-temperature liquid metal in the pump trench to the sensor 20. For example, the thickness of the insulation felt can be set to 5 mm.

[0055] like Figure 3 As shown, in some embodiments, the support assembly 13 includes a first support member 131 and a second support member 132. The first support member 131 is configured to support the second support member 132. The first support member 131 is configured to support the sensor 20, and the second support member 132 is configured to support the pump trench assembly 12.

[0056] In this embodiment, the first support member 131 and the second support member 132 support the sensor 20 and the pump groove assembly 12 respectively, and the first support member 131 supports the second support member 132 to provide an installation foundation for the sensor 20 and the pump groove assembly 12, improve the support strength, and ensure the operational stability of the high-temperature liquid metal electromagnetic pump.

[0057] Specifically, the second support member 132 can be a support flange, which is fixed to the first and last ends of the pump trench assembly 12 respectively. The first support member 131 can be a plate-shaped structure with a base. The plate-shaped structure has through holes, and the pump trench assembly 12 passes through the through holes and is fixed to the first support member 131 by the second support member 132.

[0058] like Figure 3 As shown, in some embodiments, the sensor 20 includes a winding coil 21 and a stator assembly 22, the winding coil 21 and the stator assembly 22 being configured to form a magnetic field acting on the high-temperature liquid metal, the heat insulation member 11 being configured to insulate the winding coil 21, and the stator assembly 22 being configured to support the winding coil 21.

[0059] In this embodiment, the heat insulation component 11 is configured to insulate the winding coil 21 to prevent the heat of the high-temperature liquid metal in the pump groove assembly 12 from being transferred to the winding coil 21, thereby preventing the high-temperature liquid metal electromagnetic pump from failing and improving its operational reliability.

[0060] In some embodiments, the first support member 131 is configured to support the stator assembly 22 to fix the stator assembly 22, so that it can support the winding coil 21, so that the winding coil 21 and the stator assembly 22 work together on the pump groove assembly 12, so that the traveling wave magnetic field formed by the two generates an induced current in the high-temperature liquid metal in the pump groove assembly 12.

[0061] In some embodiments, the high-temperature liquid metal electromagnetic pump further includes multiple fans, and the first support member 131 forms a cavity. The multiple fans are disposed in the cavity and are used to dissipate heat from the winding coil 21, so as to ensure the stable operation of the high-temperature liquid metal electromagnetic pump under abnormal operating conditions, such as when the ambient temperature is too high, and to avoid its failure.

[0062] In some embodiments, the winding coil 21 is configured to be detachable and removable from the stator assembly 22 as a whole. Since the high-temperature liquid metal electromagnetic pump usually requires maintenance and replacement of the winding coil 21 after long-term operation, in order to facilitate the replacement and maintenance of the winding coil 21, this embodiment configures the winding coil 21 to be detachable and removable from the stator assembly 22 as a whole. When the winding coil 21 needs maintenance and replacement, the pump groove assembly 12 can be removed without cutting, and the disassembly and installation of the winding coil 21 can be completed while ensuring the sealing of the electromagnetic pump structure.

[0063] In some embodiments, the stator assembly 22 is formed with a slot, and the winding coil 21 includes an electromagnetic wire. The electromagnetic wire is wound with multiple turns to form a disc shape and is insulated as a whole before being placed in the slot, so as to further facilitate the maintenance and replacement of the winding coil 21. When the winding coil 21 needs to be maintained or replaced, the pump groove assembly 12 can be removed without cutting, and the disassembly and installation of the winding coil 21 can be completed while ensuring the sealing of the electromagnetic pump structure.

[0064] In some embodiments, the stator assembly 22 is configured as a comb, with a slot formed between every two teeth, and the wound disc-shaped electromagnetic wire is embedded in the slot to further facilitate the overall assembly and disassembly of the winding coil 21.

[0065] In some embodiments, the electromagnetic wire material can be T2 flat copper wire with an insulating layer covering the surface. The insulating layer material can be polyimide film, mica tape, or fiberglass tape to ensure the overall insulation effect of the winding coil 21.

[0066] like Figure 4 As shown, Figure 4 The diagram shows a schematic of the structure of a pump trench assembly 12 according to an embodiment of this application. In some embodiments, the pump trench assembly 12 includes an inlet pipe 121, an outlet pipe 122, an inner through pipe 123, an outer wall pipe 124, an inner wall pipe 125, and an inner iron core 126. A conveying component for transporting high-temperature liquid metal is sealed to the inlet pipe 121. Both the outlet pipe 122 and the inlet pipe 121 are located at the beginning of the pump trench assembly 12. The outer wall pipe 124 is sleeved outside the inner wall pipe 125 and is coaxially arranged with it, forming an annular flow channel for the flow of high-temperature liquid metal. The inner iron core 126 is used to enhance the intensity of the traveling wave magnetic field generated by the sensor 20. The high-temperature liquid metal is input through the inlet pipe 121, passes through the inner through pipe 123 to the end of the pump trench assembly 12, returns to the beginning of the pump trench assembly 12 through the annular flow channel, and is output from the outlet pipe 122.

[0067] In some embodiments, the second support member 132 is fixed at both ends of the pump groove assembly 12. The second support member 132 fixed at the beginning end is disposed between the outlet pipe 122 and the end end to further facilitate maintenance and replacement. When the winding coil 21 of the sensor 20 needs to be maintained or replaced, there is no need to cut or otherwise damage the pump groove assembly 12. Under the premise of ensuring the sealing of the electromagnetic pump structure, the winding coil 21 can be disassembled and installed from the end of the pump groove assembly 12.

[0068] In some embodiments, the operating state of the high-temperature liquid metal electromagnetic pump is determined based on the temperature monitored by the temperature sensor 30, in order to prevent the high-temperature liquid metal electromagnetic pump from overheating and causing failure, and to further ensure the operational stability and reliability of the high-temperature liquid metal electromagnetic pump.

[0069] Specifically, the temperature sensor 30 is configured to monitor the temperature of the pump groove assembly 12 and the winding coil 21 of the sensor 20 to determine the current operating status of the high-temperature liquid metal electromagnetic pump, prevent the pump groove assembly 12 and the winding coil 21 from overheating, and ensure that the high-temperature liquid metal electromagnetic pump is in normal operating condition.

[0070] In some embodiments, the temperature sensor 30 is configured to monitor the temperature at different locations within the main body 10 and determine the power supply voltage of the excitation controller 40 to the sensor 20 based on the monitoring results, so as to adjust the magnitude of the induced current generated by the sensor 20 on the high-temperature liquid metal within the main body 10, thereby quantitatively heating the high-temperature liquid metal, effectively ensuring the stable operation of the high-temperature liquid metal electromagnetic pump, and facilitating the fulfillment of the high-temperature liquid metal conveying requirements of the molten salt electrolysis dry process.

[0071] Regarding the embodiments of this application, it should also be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other to obtain new embodiments.

[0072] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. The scope of protection of this application shall be determined by the scope of the claims.
