Bearing applications in the petrochemical industry (2)

To sum up, large size, high specific pressure, low energy consumption, no pollution, low noise, high reliability, long life, super lubrication, high precision, high stiffness, intelligent and other high-end sliding bearings under extreme conditions and special environments. Innovative design and manufacturing theory, method and technology are the commonality and key scientific and technological problems that China's high-end sliding bearings urgently need to solve. Energy and motion are transmitted through the interface between mechanical parts. The macro performance of mechanical equipment and parts (carrying capacity, efficiency, energy consumption and working life, adaptability and safety and reliability under various special and extreme conditions, etc.) are directly related to the mechanical, physical, and chemical forms of the interface. The latter is usually a complex phenomenon at the micro or nano scale. Traditional contact mechanics does not consider possible types of lubrication, and traditional lubrication mechanics does not consider possible interface contact. They do not completely and accurately describe the actual situation of boundary painting in engineering. Therefore, around the research and development of high-end sliding bearings in China, we need to use the ideas of system engineering to comprehensively use interface mechanics, tribology, surface engineering, system dynamics, materials science, advanced manufacturing, reliability engineering, and testing technology. And collaborative innovation design theory, method and technology, focusing on the commonality and key subjects of the following high-end sliding bearings
(1) Key scientific issues of dynamic service behavior of sliding bearings under special environments and extreme conditions;
Technical difficulties:
(2) Comprehensive performance test technology and database construction of high-end sliding bearings under multi-field coupling conditions
(3) Multi-disciplinary integration and collaborative innovation design and manufacturing theory and methods of high-end sliding bearings
(4) National standards, evaluation systems and key industrialization technologies for high-end sliding bearing products
