In the fields of electronics, automobiles, medical equipment, and new energy, power cords are critical connecting components whose reliability directly affects the overall performance and safety of products. In order to ensure that the power cord has sufficient mechanical strength and durability during long-term use, the power cord tension and torsion testing machine is widely used in the quality inspection process. This device evaluates the structural stability and connection reliability of wires by simulating mechanical environments such as tension, bending, and torsion that may be encountered in actual use.

As the core equipment to ensure the quality of medical beds, the stable operation of the medical bed comprehensive testing machine is crucial. Once a malfunction occurs, it not only affects detection efficiency, but may also delay the production and use of medical beds. Therefore, in-depth research on fault diagnosis and rapid repair techniques is of great significance. ​

In the current booming development of the new energy vehicle industry, the charging gun vehicle rolling test machine is an important equipment to ensure the safety of charging facilities. By optimizing its parameters, the test results can be made more accurate, effectively evaluating the quality and safety of the charging gun. ​

The horizontal and vertical combustion tester, as an important equipment for detecting the flame retardant performance of materials, its standardized and safe operation directly affects the accuracy of test results and personnel safety. Strictly following operating procedures and keeping safety precautions in mind are necessary prerequisites for conducting experiments smoothly. ​

The water hammer pulse testing machine is a professional detection equipment used to simulate transient pressure changes (such as water hammer effect) in pipeline systems, widely used for pressure resistance testing of products such as valves, pipes, hydraulic components, etc. In order to ensure its long-term stable operation and obtain accurate and reliable test data, it is necessary to carry out scientific and reasonable daily maintenance of the equipment and master the troubleshooting methods for common faults.
