Congratulations on the successful liftoff of Chang'e-5!

FLK helps the lunar exploration project with technological innovation and high quality products!

At 4:30 on November 24, the Long March 5 remote five carrier rocket carrying the Chang'e 5 probe pulled up and flew to the moon, opening the curtain of China's first unmanned lunar sampling return mission. Chang'e 5 mission is the sixth mission of China's lunar exploration project, which is one of the most complex and difficult tasks in China's space field so far.
In such a major mission, the high-end large-size ceramic Seal Ring produced by our company and the high-performance fully enclosed internal circulation mechanical seal system designed by our company, as the only core key equipment connecting the dynamic and static cooling pipeline, were applied to the large radar constituting the deep space measurement and control network, which significantly improved the data reception capability, detection distance and reception sensitivity, and provided strong measurement and control support for this Chang'e 5 mission and the lunar exploration project.
The project of "Development of high-end ceramic materials and sealing rings and their application in large active phased array radar", jointly completed by our company, the 14th Research Institute of China Electronics Technology Group, Tsinghua University and Hefei General Machinery Research Institute Co. The project has made significant innovations and breakthroughs in many key technologies, such as the design/sintering technology of high-end reinforced toughened ceramic materials, the manufacturing/high-precision processing technology of oversized ceramic seal rings, and the design/manufacturing technology of fully enclosed internal circulation mechanical seal system. For the first time, we have developed high-end ceramic seal ring products of 500mm size and mechanical seal system with a flow rate of 400m3/h, which successfully solved the problems faced by traditional mechanical seal systems such as cooling of megawatt-level heat consumption, high load operation, low reliability under extreme harsh environment and short service life. From China Electronics Technology Group was informed that the application of the project's innovative technology and products of the deep space antenna array system, will provide solid measurement and control and communication technology guarantee for Chang'e 5 mission, 100% full protection of the lunar exploration project mission.
