Description

Technical Field

[0001] The utility model relates to immersion test equipment, in particular to a circumferential immersion test device for metal materials and components. Background Art

[0002] For metal materials and products using metal components, the atmospheric environment in which they are used can severely impact the performance of the metal, and thus the safety and reliability of the product. Therefore, corrosion resistance testing is necessary to verify its performance and meet the requirements of actual operating conditions.

[0003] For metal materials used in atmospheric environments, corrosion typically occurs in an atmosphere with specific temperature, humidity, and solutes. Furthermore, with the alternation of day and night and changes in ambient temperature, the metal material and the corrosive medium do not maintain continuous contact, but typically exhibit a certain degree of periodicity. Conventional immersion tests use relatively simple immersion devices that fail to account for the impact of the immersion environment on test results. Furthermore, open test devices easily allow the test solution to dissolve contaminants in the external environment, resulting in the synergistic effects of multiple ions during the immersion process, which in turn affects the accuracy of the test results.

[0004] Therefore, it is of great significance to design a periodic immersion test device that can simulate a specific service environment and accurately test the corrosion degree of metal materials. Utility Model Content

[0005] The purpose of the utility model is to provide a peripheral immersion test device for metal materials and components. The device has a simple structure, can complete the metal material corrosion immersion test, and can prevent environmental pollutants from entering the immersion solution, thereby ensuring the accuracy of the metal material corrosion immersion test.

[0006] The above-mentioned purpose of the present invention is achieved through the following technical scheme: a peripheral immersion test device for metal materials and components, characterized in that: the device includes an immersion box and two immersion solution containers, the immersion box is a closed box with two liquid outlets, the box is filled with immersion solution for metal material corrosion immersion test, the immersion box is equipped with a sample table and a temperature monitor; the two immersion solution containers are arranged in parallel, and the two immersion solution containers are respectively connected to the two liquid outlets of the immersion box through pipelines, the immersion solutions contained in the two immersion solution containers are the same as the immersion solution in the immersion box, and the pipelines connecting the two immersion solution containers and the immersion box are provided with bidirectional pumps, which can control the bidirectional flow of liquid.

[0007] In the present invention, at least one side surface of the immersion box is made of transparent material, and the two liquid outlets are arranged at the bottom of the box.

[0008] In the present utility model, the two soaking solution containers are respectively the first soaking solution container and the second soaking solution container. The two-way pump arranged on the pipeline connecting the first soaking solution container and the soaking tank is a first two-way pump, and the first two-way pump divides the pipeline where it is located into two sections, namely the first liquid hose and the third liquid hose; the two-way pump arranged on the pipeline connecting the second soaking solution container and the soaking tank is a second two-way pump, and the second two-way pump divides the pipeline where it is located into two sections, namely the second liquid hose and the fourth liquid hose.

[0009] In the present invention, the first soaking solution container and the second soaking solution container both have openable end covers, and the first soaking solution container and the second soaking solution container are both heatable and heat-insulating containers.

[0010] The test device of the utility model can be monitored and manually operated by a staff member when in use. The staff member observes the solution temperature value displayed by the temperature monitor. If the solution temperature value is within the temperature value range required for the corrosion immersion test, there is no need to operate the two-way pump. If the solution temperature value is not within the temperature value range of the corrosion immersion test, the two-way pump is manually opened to allow the solution in one immersion solution container to flow into the immersion box, and at the same time, the solution in the immersion box flows into the other immersion solution container. Until the solution temperature value in the immersion box is within the temperature value range required for the corrosion immersion test, the two-way pump is closed and the corrosion immersion test begins.

[0011] The test device of the present invention can also be equipped with a control unit when in use. The control unit is connected to the temperature monitor and the bidirectional pump respectively. The control unit can receive the temperature value monitored by the temperature monitor and can also control the operation of the bidirectional pump to control the flow direction and flow rate of the liquid. At this time, the staff observes the solution temperature value through the control unit and controls the operation of the bidirectional pump through the control unit to control the flow direction and flow rate of the liquid so that the temperature value of the solution in the immersion box is within the temperature value range required for the corrosion immersion test. Then, the bidirectional pump is turned off and the corrosion immersion test begins.

[0012] Compared to existing technologies, the test device of this utility model can control the temperature of the immersion solution within the required temperature range for corrosion immersion testing, either manually or with the help of a control unit, based on the service environment of the test material. The immersion solution is circulated through a bidirectional pump and a heatable container to simulate an immersion process under a specific time cycle. Furthermore, the sealed immersion chamber isolates the external atmosphere, preventing environmental pollutants from entering the immersion solution, thereby ensuring the accuracy of the metal material corrosion immersion test.

DETAILED DESCRIPTION

[0017] Example 1

[0018] like Figure 1 The immersion test device for metal materials and components shown in the figure includes an immersion box 1 and two immersion solution containers connected to the immersion box 1 through pipelines. The four sides of the immersion box 1 are all made of transparent materials. The immersion box 1 is a closed box with two liquid outlets. The two liquid outlets are arranged at the bottom of the box body. The box is filled with immersion solution for corrosion immersion test of metal materials. The immersion box 1 is equipped with a sample table 1-1 and a temperature monitor 1-2; the two immersion solution containers are arranged in parallel, and the two immersion solution containers are respectively connected to the two liquid outlets of the immersion box 1 through pipelines. The immersion solutions contained in the two immersion solution containers are the same as the immersion solution in the immersion box 1. The pipelines connecting the two immersion solution containers to the immersion box 1 are both provided with bidirectional pumps, which can control the bidirectional flow of liquid.

[0019] In this embodiment, the two soaking solution containers are respectively a first soaking solution container 2 and a second soaking solution container 3. The two-way pump arranged on the pipeline connecting the first soaking solution container 2 and the soaking tank 1 is a first two-way pump 4. The first two-way pump 4 divides the pipeline in which it is located into two sections, namely a first liquid hose 6 and a third liquid hose 8; the two-way pump arranged on the pipeline connecting the second soaking solution container 3 and the soaking tank 1 is a second two-way pump 5. The second two-way pump 5 divides the pipeline in which it is located into two sections, namely a second liquid hose 7 and a fourth liquid hose 9.

[0020] In this embodiment, the first soaking solution container 2 and the second soaking solution container 3 both have openable end covers and are both heatable and heat-insulating containers.

[0021] When the device is in use, it can be monitored and manually controlled by staff. When in use, the top sealing covers of the first immersion solution container 2 and the second immersion solution container 3 are opened to add immersion solution, the door of the immersion box 1 is opened, the metal sample is fixed on the sample table 1-1, the temperature monitor 1-2 is turned on, and the staff observes the solution temperature value displayed on the temperature monitor. After the immersion solutions in the first immersion solution container 2 and the second immersion solution container 3 reach the specified temperature range, the operation mode of the first two-way pump 4 and the second two-way pump 5 is manually set according to the solution temperature value in the box, so that the solutions in the corresponding immersion solution containers enter the immersion box 1, and the solution temperature value in the box is observed in real time. After the solution temperature value in the box reaches the specified temperature range and the immersion solution submerges the metal sample, the two-way pump is turned off to start corrosion immersion.

[0022] As an improvement to this embodiment, the device may also be equipped with a control unit, which is connected to the temperature monitors 1-2 and the bidirectional pump, respectively. The control unit can receive the temperature values ​​monitored by the temperature monitors 1-2 and can also control the operation of the bidirectional pump to control the flow direction and flow rate of the liquid. During use, the staff can monitor and operate the device through the control unit.

[0023] During use, open the top sealing covers of the first immersion solution container 2 and the second immersion solution container 3 and add the immersion solution, open the door of the immersion box 1, fix the metal sample on the sample table 1-1, turn on the temperature monitor 1-2, observe the solution temperature value displayed by the temperature monitor, and after the immersion solutions in the first immersion solution container 2 and the second immersion solution container 3 reach the specified temperature range, set the operation mode of the first two-way pump 4 and the second two-way pump 5 through the control unit, so that the solution in the first immersion solution container 2 enters the immersion box 1, and start immersion after the immersion solution submerges the metal sample.

[0024] Furthermore, in this embodiment, the metal sample needs to be kept immersed in a solution at 40-45°C. During the immersion process, the temperature monitor 1-2 monitors the temperature of the immersion solution. The staff operates the control unit to control the first two-way pump 4 and the second two-way pump 5 according to the solution temperature. The temperature of the immersion solution in the immersion tank 1 is maintained by adding the insulation solution in the second immersion solution container 3 to the immersion tank 1 and pumping the immersion solution with a lowered temperature from the immersion tank 1 back into the first immersion solution container 2.

[0025] Example 2

[0026] Different from Example 1, in this embodiment, soaking in a solution at 25-30°C for 1 hour + stopping for 1 minute is regarded as one cycle. During the soaking process, the temperature monitor 1-2 monitors the temperature of the soaking solution. The staff operates the control unit to control the first two-way pump 4 and the second two-way pump 5 according to the solution temperature. By adding the insulation solution in the second soaking solution container 3 to the soaking tank 1 and pumping the soaking solution with the lowered temperature back from the soaking tank 1 to the first soaking solution container 2, the temperature of the soaking solution in the soaking tank 1 is maintained. After soaking for 1 hour, the soaking solution in the soaking tank 1 is pumped back to the first soaking solution container 2 through the first two-way pump 4 and heated and kept warm. After stopping for 1 minute, the insulation solution in the second soaking solution container 3 is input into the soaking tank 1 through the second two-way pump 5 for the next heating cycle. The periodic soaking test is completed by repeating this cycle.

[0027] The above embodiments of the present invention are not intended to limit the scope of protection of the present invention, and the implementation methods of the present invention are not limited thereto. All other modifications, replacements or changes made to the above structure of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in this field, without departing from the above basic technical ideas of the present invention, should fall within the scope of protection of the present invention.
