Applications in Machine Component Inspection - Bearings
The overheating of the bearing will lead to equipment failure, but in general, users only use monitoring methods to monitor vibration and temperature after installing sensors on the bearing, so as to determine whether the bearing is faulty. But in fact, this method can only solve the monitoring problem on one side, but when the bearing is running fast, the contact temperature detection cannot be used at all, so it is impossible to monitor and judge. Therefore, if a thermal imager is used, it will be a good alternative analysis method, because the thermal imager captures the thermal image for a short time and intuitively makes better judgments than other methods.

Nondestructive detection
When heating some workpiece products, a heat flow propagation process can be formed in the workpiece. The defective and non-defective areas of the workpiece will have different surface temperatures due to the difference in thermal conductivity. When there are defects inside the object, a temperature difference will be formed between the defective and non-defective areas of the object; and the temperature difference depends on the object. In addition to the thermophysical properties of the material, it is also related to the size of the defect, the distance from the surface and its thermophysical properties; due to the existence of the local temperature difference of the object, the infrared radiation intensity will inevitably be different, then the infrared thermal imager can be used to detect it. Temperature changes, and then determine the defect situation.

Security testing
In the industrial field, key mechanical and electrical equipment will have strict requirements on the working environment. Traditionally, the monitoring of key industrial equipment is mainly completed by manual periodic scanning, but it cannot completely effectively avoid the occurrence of unexpected power failures, operation interruptions and equipment failures. If the equipment fails, it will cause incalculable economic losses to the enterprise. For example, the loss caused by the failure of the motor due to overheating or heating of the joint of the high-voltage transmission line during operation is more difficult to estimate. Thermal imaging has proved that it is possible to perform daily infrared inspections on processing equipment, production lines and other supporting power facilities, as well as to judge and evaluate the health of equipment and wear characteristics. At the same time, the longitudinal temperature data obtained by thermal imaging can be used for maintenance. Planning is very helpful.
