On January 7, an expert appraisal committee headed by Academician Wang Yuming of the Chinese Academy of Engineering announced in Fuyang that China's first breakthrough in magnetic bearing technology research and development, and the first application of magnetic suspension technology in China - FS450 molecular pump based on cross-feedback control Magnetic bearings, successfully developed by Zhejiang Feixing Technology Co., Ltd., a subsidiary of "China's Top 500 Private-owned Enterprises " of Zhejiang Feihong Group, broke the monopoly of technology in foreign countries and made our country become a few developed countries such as France, the United States, Canada, Germany and so on With independent intellectual property rights of magnetic bearing manufacturing technology countries.
"Magnetic bearings, also known as active magnetic bearings, are another revolution in the bearing industry after oil-lubricated and air lubricated." Academician Wang Yuming said that magnetic bearings are a new type of high-performance, non-mechanical contact between a rotor and a stator Bearings, the role of the use of electromagnetic force to the rotor suspended in space, in the form or from the state, with no mechanical wear and tear, low energy consumption, allowing high speed, less noise, long life, no lubrication media and so on. At present, the annual output of the world is only about 30,000 units.
This sophisticated mechatronic products, in addition to the vacuum molecular pump applications, but also in the military, aerospace, petroleum, petrochemical , energy and other fields have broad prospects. Therefore, the magnetic bearing technology is internationally sensitive technology. For important applications, developed countries have restrictions on exports to China, which means that the greatest cost may not be able to be purchased.
Hongshangping, general manager of Zhejiang Spinning Technology Co., Ltd., is the research and development team responsible for the project. With the technical support of Tsinghua University Institute of Nuclear Energy and New Energy Technology, it successfully pioneered the development and application of molecular pump magnetic bearings for integrated circuit equipment applications in China. It is learned that several prototypes of the molecular pump magnetic bearing prototypes developed by Cyclocon Technology have passed the trial of the users and the next step they will carry out batch process research and industrialization as soon as possible.
