Shen drum group research institute "nuclear pump bearing the surfacing technology parameters optimization" research and development success, broke through the domestic nuclear power equipment development bottlenecks, turn the nuclear pump water bearing long-term foreign monopoly by the passive state, for promoting the localization of nuclear power equipment is important.
Building large PWR, is the national development strategy, listed in the national 16 major special one. As the core of the nuclear pump nuclear power plant equipment, localization of the most difficult, because special operation condition, main part--water bearing must have good shock sex, thermal conductivity and high strength, low friction coefficient. Shen drum group for the nuclear pump localization of the major mission, conquer the domestic high-end water bearing surface strengthening technical problem, is increasingly the delay.
In view of the importance of the project, the tip of the technology gender, shen drum group research institute and shen drum-a great work to set up research topic, and through the study repeatedly, continuous optimization of success. Surface strengthening water bearing installed, withstand all the running condition assessment, the running effect is good. The experts identified, reaching the international advanced level.
The results accord with the national long-term plan for science and technology development "requirement, has been used in the development
CPR1000 nuclear power plant factory with the important of pumps and nuclear secondary pump (including the secure spray pump, low voltage Ann note pump discharge, waste heat pump, electric auxiliary pump and filling the pump), made remarkable economic and social benefits. The results are applied to the Westinghouse AP1000 nuclear Lord three generations of nuclear power of the pump localization, and for the development of independent intellectual property rights of the main pump nuclear laid a solid foundation of the technology.
Shen drum group, through the combination of tackling key problems, with the 1000 MW nuclear power units nuclear secondary pump batch supply capacity, and to promote the ability of independent innovation, enhance the enterprise competitiveness.
