Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sealing cap crack detection, more specifically, the utility model relates to a kind of detection equipment for thermocouple sealing cap crack. BACKGROUND

[0002] In many fields of industrial production and scientific research, thermocouples are widely used in various complex working conditions such as high temperature and high pressure as an important temperature measurement sensor. The performance of the thermocouple is crucial to the accuracy and reliability of temperature measurement, and its sealing cap plays a key role.

[0003] On the one hand, the sealing cap can protect the sensitive elements of the thermocouple from the erosion of the external harsh environment, such as corrosive gases in chemical production and oxidizing atmosphere around high-temperature furnaces. If the sealing cap has cracks, these corrosive substances or high-temperature gases may penetrate into the thermocouple, directly affecting the measurement accuracy and causing measurement errors. In some production processes that require high temperature control, such as semiconductor manufacturing and precision material synthesis, even a small temperature measurement error can lead to a decline in product quality and cause significant economic losses.

[0004] On the other hand, in the energy field, such as thermal power generation, a large number of thermocouples are used to monitor the temperature of key equipment such as boilers. The cracks in the sealing cap may cause the thermocouple to lose its sealing properties in high-temperature and high-pressure environments, thereby affecting the stable operation of the entire thermal system. Once a fault occurs, it may cause safety accidents, threatening the safety of personnel and the normal operation of equipment.

[0005] Therefore, before use, the sealing cap needs to be detected for cracks to ensure the accuracy of temperature measurement. Therefore, a detection device for thermocouple sealing cap cracks is proposed. SUMMARY
