Embodiment 1

[0038] Such as figure 1 , 2 shows the coating anti-high frequency thermal pulse fatigue test device, which includes an electronic control system 1, a lifting and rotating device 2, two special sample racks: sample rack A3 and sample rack 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 electronic 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 installed coating samples (6) to move up, down and counterclockwise high-frequency rotation. The low temperature tank 8 and the high temperature tank 7 are located vertically below the two sample racks.

Description

Technical field [0001] The invention relates to the technical field of structural design and application of a protective material rapid evaluation experimental device, and in particular provides a protective material anti-cold and heat pulse fatigue test device. Background technique [0002] In the prior art, the pipeline heat exchange and transportation systems of oil, gas, and water-liquid systems include pump bodies, valves and other fittings. In order to prevent corrosion and abrasion of the inner wall transportation medium, lining protective materials are generally used for protection. Because the temperature of the liquid medium conveyed inside the heat exchange system generally fluctuates in the range of -25℃~100℃, the short-term temperature difference reaches 20℃~100℃, and the rapid cold and heat alternating temperature change cycle is an environment where the temperature change is ≥10 seconds. There is an urgent need to develop a test device that can simulate the above-m...
