On November 24, the Long March 5 Yaowu carrier rocket successfully launched the lunar exploration project Chang'e 5 probe at the Wenchang Space Launch Site in China.
China's leading silicon carbide ceramic materials and silicon carbide ceramic precision parts technology company, the large-size precision ceramic seal ring and high-performance fully enclosed internal circulation mechanical seal system developed and produced by NBFE Advanced Ceramic Materials Technology Co., Ltd. are used in the deep In the large radar of the air measurement and control network, as a core key equipment, it helped Chang'e-5 expedition to the moon. This is also the first time that China has manufactured a mechanical seal material with a diameter of 500 millimeters that can meet the requirements of megawatt-level large radar applications.

Xie Fangmin, CTO of NBFE, said that the heating of radar will cause the burning of electronic components, which requires the "protection" of the cooling system. The lunar exploration project has high requirements on the radar’s data receiving ability, detection range and receiving sensitivity. The radar size has become larger, the power has reached the megawatt level, and the cooling system has also been upgraded. The large-size precision ceramic seal ring developed by NBFE is just a large The core component of the radar cooling system, the larger the size of the seal ring, the better the performance, and the longer the life, the stronger the cooling effect, which is more conducive to the improvement of radar performance.
In the inspection department of NBFE, you can see the large-size precision ceramic sealing ring participating in this lunar exploration project. It is in a gray ring shape, light in weight, and smooth in surface. The two main bodies are attached and rotated to play a sealing role. .
The preparation of large-size precision ceramic sealing rings is a comprehensive manifestation of the technical strength of "NBFE". This advanced ceramic material technology company has been deeply involved in the field of special ceramic materials for more than 30 years. With innovative research and development as the driving force for development, it has participated in the formulation of more than ten national and industry standards and obtained 17 invention patents. Platforms such as national demonstration academician workstations, provincial postdoctoral workstations, and provincial engineering ceramics high-tech research and development centers have been built, and a talent echelon of more than 40 people has been introduced. Recently, the company has also been included in the list of China's "hidden champion" companies.
NBFE advanced ceramic materials and precision components are not only used in the aerospace field, but also have broad prospects in the fields of national defense, energy, semiconductors, etc.
