Description

Technical Field

[0001] This utility model relates to the field of internal corrosion technology, and in particular to a structure of a vertical cyclic corrosion test chamber. Background Technology

[0002] Internal corrosion refers to the corrosion that occurs inside materials or components (such as the inner wall of pipes, the inner cavity of containers, and the internal channels of metal structures) due to chemical, electrochemical, or physical interactions with environmental media (such as liquids, gases, and direct leachates). It is widely present in key fields such as petrochemicals, energy, aerospace, and marine engineering.

[0003] Existing internal corrosion testing equipment is mostly static testing equipment, which is difficult to simulate the state of medium circulation flow in actual working conditions, resulting in a large deviation between the test results and the actual corrosion situation. At the same time, some circulating corrosion test chambers have deficiencies in temperature control accuracy, medium parameter monitoring, and water pressure control, and cannot meet the requirements of high-precision, multi-parameter corrosion testing. Therefore, it is necessary to design a vertical circulating corrosion test chamber structure to control the flow rate, flow velocity, and temperature under medium flow conditions to achieve the purpose of the test. Utility Model Content

[0004] The purpose of this utility model is to propose a vertical cyclic corrosion test chamber structure in order to solve the above-mentioned problems.

A drain pipe is connected to one side of the high-low temperature circulating water bath, and a collection box is connected to one end of the drain pipe. A test pipe is connected to one side of the collection box. An insulated test chamber is installed on the outer wall of the test pipe. A circulation pipe is connected to one side of the insulated test chamber. A medium tank is installed inside the high-low temperature circulating water bath. Circulation pumps are installed on the drain pipe, the test pipe, and the circulation pipe. Ball valves are installed inside the test pipe and the drain pipe. A thermometer is installed inside the collection box. A pressure sensor is installed on the collection box. A flow meter is installed on the test pipe. A sample placement rack is fixedly connected to the inner wall of the insulated test chamber. A nozzle is installed at the end of the test pipe. A clamping assembly is installed on the sample placement rack.

[0006] Preferably, the outer wall of the drain pipe is connected to a Y-type filter.

[0007] Preferably, the number of nozzles is set to multiple, and the multiple nozzles are connected by threads to the end of the test pipe located inside the thermal insulation test chamber.

[0008] Preferably, a level gauge is installed on the top of the medium tank, and a buzzer is provided on one side of the level gauge.

[0009] Preferably, a transparent observation window is fixedly connected to one side of the thermal insulation test chamber.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this application, the entire set of equipment provides the test medium through the medium tank, which is then sent to the heat preservation box by the circulation pump through the collection box. The sample is then tested, and the tested medium is recycled back into the medium tank through the circulation pipe. The medium passes through the collection box and the test pipeline.

[0015] Please see Figure 1-4 This utility model provides a technical solution: like Figure 1-4 As shown, a vertical cyclic corrosion test chamber structure includes a high-low temperature circulating water bath 1. A drain pipe 2 is connected to one side of the high-low temperature circulating water bath 1, and a collection box 3 is connected to one end of the drain pipe 2. A test pipe 4 is connected to one side of the collection box 3. An insulated test chamber 5 is installed on the outer wall of the test pipe 4. A circulation pipe 6 is connected to one side of the insulated test chamber 5. A medium tank 7 is installed inside the high-low temperature circulating water bath 1. A circulation pump 8 is installed on the drain pipe 2, the test pipe 4, and the circulation pipe 6. A ball valve 9 is installed inside the test pipe 4 and the drain pipe 2. A thermometer 10 is installed inside the collection box 3, which can observe the temperature of the medium in real time. A pressure sensor 11 is installed on the collection box 3, which can detect the water pressure of the medium in a timely manner. A flow meter 12 is installed on the test pipe 4. A sample placement rack 13 is fixedly connected to the inner wall of the insulated test chamber 5. A nozzle 14 is installed at the end of the test pipe 4, which can spray the medium into the inner wall of the sample. A clamping assembly is installed on the sample placement rack 13.

[0016] like Figure 2 As shown, a Y-type filter 15 is connected to the outer wall of the drain pipe 2. Multiple nozzles 14 are provided, and the multiple nozzles 14 are connected to the end of the test pipe 4 located inside the heat preservation test chamber 5 by threads. A liquid level gauge 16 is installed on the top of the medium tank 7. The liquid level gauge 16 can observe the liquid level in the medium tank 7 in real time. A buzzer 17 is provided on one side of the liquid level gauge 16. The buzzer 17 can emit a sound to remind the surrounding staff that the liquid level in the medium tank 7 is low. A transparent observation window 18 is fixedly connected to one side of the heat preservation test chamber 5. The clamping assembly includes a waterproof electric actuator 19 and a clamping plate 20. A waterproof electric actuator 19 is fixedly connected to the outer wall of the sample placement rack 13. A clamping plate 20 is installed at one end of the waterproof electric actuator 19. There are two clamping plates 20. The two clamping plates 20 are arranged in a mirror symmetrical manner with the nozzle 14 as the center. The two clamping plates 20 can squeeze and fix the sample from both sides, thereby preventing the flowing medium from pushing the sample to move.

[0017] Working Principle: In this embodiment, the vertical cyclic corrosion test chamber structure is used by the operator. First, the sample is placed inside the sample placement rack 13, with the nozzle 14 aimed at the inside of the sample. Then, the operator moves the clamping plates 20 using the waterproof electric actuator 19, clamping and fixing the sample from both sides. Next, the high and low temperature circulating water bath 1 heats the medium in the medium tank 7 to the specified temperature. Then, the medium is discharged into the collection tank 3 through the circulating pump 8 and drain pipe 2. The Y-type filter 15 on the drain pipe 2 filters the medium. Inside the collection tank 3, the temperature and water pressure of the flowing medium are monitored in real time by a thermometer 10 and a pressure sensor 11. The medium then flows into the insulated test chamber 5 through the test pipe 4. The flow rate in the test pipe 4 is... The meter 12 monitors the medium flow rate in real time. Then, the medium in the test pipe 4 is sprayed into the sample through the nozzle 14, thereby conducting an internal corrosion test on the sample through the medium. The staff can observe the test situation inside the insulation test chamber 5 through the transparent observation window 18. The medium inside the insulation test chamber 5 is discharged back into the medium tank 7 through the circulation pipe 6, thereby completing the medium circulation and enabling the medium to be recycled and reused. The medium tank 7 is equipped with a level gauge 16. If the level is lower than the predetermined level, an alarm will be triggered by a buzzer, which will shut down the high and low temperature circulating water bath 1 to prevent dry burning in the medium tank 7. In this way, the flow rate, velocity, and temperature can be controlled by the ball valve 9, flow meter 12, thermometer 10, pressure sensor 11, etc. in the acquisition box 3 and the test pipe 4 to achieve the purpose of the test.

[0018] In summary, the entire system provides the test medium through the medium tank 7, which is then pumped through the circulation pump 8 and the collection tank 3 to the heat preservation test chamber 5. The sample is then tested. After the test, the medium is recycled back into the medium tank 7 through the circulation pipe 6. The medium passes through the collection tank 3 and the test pipeline 4. The ball valve, flow meter 12, thermometer 10, pressure sensor 11, etc. in the collection tank 3 and the test pipeline 4 are used to control the flow rate, velocity, and temperature to achieve the purpose of the test.
