Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to an anti-thermal shock experimental device. Background Technology

[0002] When materials and their products are subjected to drastic temperature changes that cause internal temperature gradients, thermal stress will be generated inside the material due to the obstruction of contraction or expansion. When the thermal stress exceeds the material's strength limit, phenomena such as cracking, damage, and reduced mechanical strength will occur. Thermal shock resistance is the ability of materials and their products to resist drastic temperature changes without damage or destruction. There are many test methods for thermal shock resistance, such as repeatedly raising the material to different temperatures and then quenching it, and measuring the number of thermal cycles that cause cracking on the sample surface. Thermal shock resistance tests are widely used in the performance testing of various refractory materials and high-temperature coatings.

[0003] For example, the authorized patent with announcement number CN 220271079 U (an experimental device for thermal shock resistance of automatic quantitative watering) includes an experimental device body, which is a cuboid structure. The lower part is equipped with a heating device and a water holding device, the middle part is equipped with an electric push rod, the upper outer part is equipped with a controller and a PC all-in-one machine, and the top is equipped with a temperature measuring device and a water supply device. One end of the electric push rod is a heating position and the other end is a detection position. The temperature measuring device and the heating device are respectively located at the top and bottom of the heating position, and the water supply device and the water holding device are respectively located at the top and bottom of the detection position.

[0004] While the existing technologies described above are simple in structure, low in cost, and stable in performance, they rely on single-point cooling via a single water pipe, which is not conducive to uniform cooling of the sample material. Consequently, existing experimental equipment is not suitable for multi-point cooling of the sample material during thermal shock resistance tests, affecting the uniformity of cooling. Therefore, there is an urgent need in the market to develop a thermal shock resistance testing device to help people solve the existing problems. Utility Model Content

[0024] During use, in the process of thermal shock resistance test, by introducing water pumps symmetrically installed in the pump box 14 and connected to them water delivery pipes 15, distributors 16 and multiple inclined and longitudinally spaced nozzles 17, the uniformity of sample material cooling can be improved, so that cooling water can be sprayed onto the sample material from multiple points in a more uniform manner.
