Description

Technical Field

[0001] This utility model relates to the field of materials testing, and more specifically, to an integrated corrosion liquid circulation device for stress corrosion fatigue testing. Background Technology

[0002] In stress corrosion fatigue testing of materials, it is necessary to simulate the working conditions of materials subjected to alternating stress in a corrosive environment;

[0003] A search revealed an existing patent (publication number: CN211972494U) that discloses a circulating corrosion device for simultaneously injecting liquid into both sides of an electrode foil. The device includes an corrosion tank filled with corrosive liquid, a circulating liquid tank and an electrode foil inside. The circulating liquid tank is fixed to the side wall of the corrosion tank, with its top extending beyond the surface of the corrosive liquid. Electrode plates are symmetrically arranged on both sides of the plane containing the electrode foil, parallel to the electrode plates. Diverter pipes are symmetrically arranged on both sides of the electrode foil, forming a cavity through which the electrode foil flows in and out. The diverter pipes are connected to a circulation pipe, which in turn is connected to a pump body installed at the bottom of the circulating liquid tank. This invention achieves the effect of uniformly injecting corrosive liquid from the diverter pipes on both sides of the electrode foil, and then flowing out from the electrode plate holes, thus mitigating the impact of temperature changes on the aluminum foil during the electrochemical reaction. The circulation pipe, connected to the pump body, draws filtered corrosive liquid from the circulating liquid tank and injects it uniformly through the diverter pipes, enabling the recycling of the corrosive liquid within the corrosion tank.

[0004] Existing samples are easily affected by the impact of liquid flow and buoyancy in the corrosion liquid circulation device, which makes the stress distribution of the sample uneven and may cause local stress concentration, thus affecting the accuracy and repeatability of the test results and resulting in certain limitations in its use. At the same time, the patent documents cited above do not propose relevant solutions to solve the above problems.

[0005] Therefore, an integrated corrosion liquid circulation device for stress corrosion fatigue testing is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide an integrated corrosion liquid circulation device for stress corrosion fatigue testing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an integrated corrosion liquid circulation device for stress corrosion fatigue testing, comprising a storage tank, one side of which is connected to a limiting component via a water pipe, the limiting component comprising a test chamber, wherein electric telescopic rods are symmetrically and fixedly arranged inside the test chamber, a slider is fixedly connected to one side of the electric telescopic rod, and a connecting frame is provided on one side of each slider, both ends of each connecting frame are provided with a rotating shaft, and a buffer pad is fixedly provided on one side of each connecting frame, and a limiting plate is fixedly arranged on the other side inside the storage tank.

[0008] Preferably, the test chamber has symmetrical grooves at both ends inside, and the grooves are slidably connected to the slider.

[0009] Preferably, the upper end of the storage tank is provided with a stirring assembly, the stirring assembly includes a drive motor, a rotating shaft is driven to one side of the drive motor, and stirring rods are symmetrically and fixedly installed at both ends of the rotating shaft.

[0010] Preferably, a cleaning component is provided on the outside of the storage box. The cleaning component includes a water tank, and a rotary joint is connected to one side of the water tank through a fixed pipe. The rotary joint is located inside the storage box.

[0011] Preferably, the bottom of the rotary joint is connected to an annular sleeve via a flexible hose, the annular sleeve is sleeved with the rotating shaft, and both ends of the annular sleeve are connected to atomizing nozzles via diverter pipes.

[0012] Preferably, a filter plate is snapped onto the upper end of the water pipe, a circulation pump is provided on one side of the filter plate, and a flow regulating valve and a pressure sensor are provided on the other side of the water pipe.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] Compared with existing technologies, this integrated corrosion liquid circulation device for stress corrosion fatigue testing uses a limiting component. The connecting frame and the limiting plate work together to limit the position of the sample, ensuring that the sample position is stable during the test and will not be displaced or shaken due to factors such as the flow of corrosion liquid or vibration of the test equipment. This effectively avoids the phenomenon that changes in the sample position lead to uneven stress distribution, which affects the reliability of the test data, thus enhancing its practicality.

A slider 43 is fixedly connected to one side of the electric telescopic rod 44, and a connecting frame 45 is provided on one side of each slider 43. A rotating shaft 46 is provided at both ends of each connecting frame 45, and a buffer pad 47 is fixedly installed on one side of each connecting frame 45. A limiting plate 48 is fixedly installed on the other side of the storage tank 1.

[0023] The device is equipped with an electric telescopic rod 44, which connects the sliders 43 to a connecting frame 45 via a rotating shaft 46. This frame works in conjunction with a limiting plate 48, allowing the device to be adjusted according to different sample specifications, thus improving its practicality to a certain extent.

[0024] Example 2

[0025] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0026] As a preferred embodiment, the test chamber 41 has symmetrically provided grooves 42 at both ends inside, and the grooves 42 are slidably connected to the slider 43; furthermore, by providing the grooves 42, the grooves 42 improve the stability of the slider 43 when it moves.

[0027] The storage tank 1 is equipped with a stirring assembly 2 at the top. The stirring assembly 2 includes a drive motor 21. A rotating shaft 22 is connected to one side of the drive motor 21. Stirring rods 23 are symmetrically and fixedly installed at both ends of the rotating shaft 22. Furthermore, by providing the drive motor 21, the drive motor 21 drives the stirring rods 23 to rotate, thereby stirring and mixing the reagent and the corrosive liquid, making it more convenient to use.

[0028] The storage box 1 is equipped with a cleaning component 3 on its exterior. The cleaning component 3 includes a water tank 31. A rotary joint 33 is connected to one side of the water tank 31 through a fixed pipe 32, and the rotary joint 33 is located inside the storage box 1. Furthermore, by providing the rotary joint 33, wear and friction at both ends can be reduced during rotation, thereby improving its service life.

[0029] The bottom of the rotary joint 33 is connected to an annular sleeve 35 via a flexible hose 34. The annular sleeve 35 is sleeved with the rotating shaft 22, and both ends of the annular sleeve 35 are connected to atomizing nozzles 37 via diverter pipes 36. Furthermore, by providing atomizing nozzles 37, when the inside of the storage box 1 needs to be cleaned, the inside of the storage box 1 can be cleaned by spraying, making it more convenient to use.

[0030] A filter plate 6 is snapped onto the upper end of the water pipe 5. A circulation pump 7 is installed on one side of the filter plate 6, and a flow regulating valve 8 and a pressure sensor 9 are installed on the other side of the water pipe 5.

[0031] The working process of this utility model is as follows:

[0032] In use, firstly, an appropriate amount of corrosive solution is added to the storage tank 1. Then, the drive motor 21 is turned on, causing the rotating shaft 22 to rotate, which in turn rotates the stirring rods 23 at both ends, mixing the corrosive solution and reagent inside the storage tank 1. A uniformly mixed reagent can more accurately simulate the chemical composition of the corrosive solution under actual working conditions, improving the reliability of the test data. Next, the circulation pump 7 is started, pumping the corrosive solution from the storage tank 1 to the test chamber 41. During circulation, it passes sequentially through the filter plate 6 on one side of the water pipe 5, filtering the corrosive solution. The flow rate of the corrosive solution can be precisely controlled by adjusting the flow regulating valve 8. Furthermore, a pressure sensor 9 is installed to monitor the flow rate in real time. The pressure changes in the corrosion liquid circulation device are monitored, making its application range wider. In addition, electric telescopic rods 44 are installed on both sides inside the test chamber 41. The electric telescopic rods 44 can drive the sliders 43 to move. The sliders 43 are connected to the connecting frame 45 through the rotating shaft 46 and work with the limiting plate 48, so that it can be adjusted according to different specifications of samples, making its application range wider. Finally, a water tank 31 is installed outside the storage tank 1. When it is necessary to clean the inside of the storage tank 1, the water tank 31 is connected to the hose 34 through the fixed pipe 32 and the rotating joint 33. The cleaning water is sprayed to clean the inside of the storage tank 1 through the atomizing nozzle 37 on one side of the diversion pipe 36, which enhances its practicality.
