Embodiment 1

[0038] Such as figure 1 , 2 shows the coating anti-high-frequency thermal pulse fatigue test device, which includes an electric control system 1, a lifting and rotating device 2, two special sample holders: sample holder A3 and sample holder B4, two test tanks: high temperature tank 7 and low temperature tank 8.

[0039] The sample rack A3 and the sample rack B4 are respectively vertically fixed on the left and right supports of the lifting and rotating device. The electric control system 1 automatically controls the cylinder lifting and rotating device 2 to drive the sample holder A3 and the sample holder B4 of the two coated samples (6) to perform upward, downward and counterclockwise high-frequency rotation movements. The low temperature tank 8 and the high temperature tank 7 are located vertically below the two sample racks.

The apparatus has the advantages of high automation degree, good temperature stability and excellent technological effects.

Description

technical field [0001] The invention relates to the technical field of structural design and application of a protective material rapid evaluation experiment device, and in particular provides a protective material anti-cold and heat pulse fatigue test device. Background technique [0002] In the prior art, the inner walls of pipeline heat exchange transportation systems for oil, gas, and water-liquid systems, including pump bodies, valves and other accessories, are generally protected by lining protective materials to prevent corrosion and wear of the inner wall transportation medium. Since the temperature of the liquid medium conveyed inside the heat exchange system generally fluctuates continuously within the range of -25°C to 100°C, the short-term temperature difference reaches 20°C to 100°C, and the temperature change cycle of the rapid cold and heat alternation is ≥10 seconds. There is an urgent need to develop a test device that can simulate the above-mentioned use en...
