The principle adopts ultrasonic small tube radial flow detection technology to perform external, non-destructive flow detection, analysis, judgment and printing on each coil cooling tube of the generator stator and rotor. It can ensure the stability and repeatability of this type of pipe and pipe diameter. The development of new electronic components is outstanding, the growth of component products is 2.1 percentage points higher than the industry average, and the electronic component industry and the information industry as a whole have ushered in-wide. Combined with the actual situation of new product development in this institute, some problems in the use of components are explained, the significance of component aging screening is provided, some statistical data of aging screening are provided, and the measures adopted by the institute for aging screening are introduced. Several measures and the effects of screening. The basic units that make up the system are electronic components and mechanical parts, so the reliability of the system depends largely on the reliability of the components. Without high-reliability components, even the most complete design can hardly make the system meet the requirements of high reliability, so component aging screening is crucial. But at present, some of our designers have a vague understanding of the screening of components. They overestimate the quality of the existing components, and even have resistance to the requirements of the institute to screen. Therefore, the author believes that it is necessary to express some opinions on this issue. Main Problems Existing in the Use of Electronic Components It is understood that the main problems that some units currently have when using electronic components are that the relevant departments have not developed a list of preferred components, so that designers cannot follow the selection and use of components.
