四川日机密封件股份有限公司与中科华核电技术研究院联合研发的压水堆核电站核二、三泵机械密封样机前不久通过鉴定，标志着该技术已成功被我国掌握。 本次通过鉴定的样机为二代加压水堆核电站核二、三级泵用机械密封样机，是国内首台同类产品的机械密封样机。核电站中的泵类产品属于关键设备，而机械密封作为核级泵上与水力模型、轴承并列的三大关键技术之一，长期以来，由于国内不能自主制造，在建电站的核级泵机械密封全部依赖国外进口。 密封件属于易损耗品，按照一个百万千瓦核电站的设计寿命周期40年计算，用于密封件方面的市场就将超过20亿元。到2020年，我国建成和在建的核电装机容量将超过1亿千瓦，密封件市场总量将超过2000亿元。 该鉴定会是由中国机械工业联合会受国家能源局委托，在成都组织召开的。中国工程院院士叶奇蓁领衔的专家组对该研究成果给予了高度评价：“样机的研制成功满足了技术规格书的要求，填补了国内空白，并达到了国外先进水平。” 四川日机公司目前正承担着纳入国家“十一五”科技支撑计划的核电主泵机械密封的研制工作，预计在2012年可以完成。届时，将形成包括主泵机械密封在内的一套完整的具有自主知识产权的核电机械密封技术，对于我国加快核电建设，改善能源结构，节能减排等方面的工作将起到积极的促进作用。

Japan Machine Co., Ltd. Sichuan, seals and China Nuclear Power Technology Research Institute in the Division jointly developed PWR Nuclear Power Plant two or three pump mechanical seal prototype recently passed appraisal indicates that the technology has successfully been our grasp. The prototype for the second generation through the identification of additional PWR Nuclear Power Plant 2, 3 pump mechanical seal prototype, is China's first prototype of similar products, mechanical seal. Nuclear power plant in the pumps is the key equipment, and mechanical seal pumps, on a nuclear and hydraulic models, bearing one of three key techniques in parallel, long time, because China can not independently create, in the construction of nuclear power stations pump mechanical seal All dependent on foreign imports. Seals are easy to wear and tear items, according to a million-kilowatt nuclear power plant's design life cycle of 40 years calculated for seals and a market will be more than 2 billion yuan. By 2020, China completed the construction of nuclear power installed capacity and will be more than 100 million kilowatts, seals will be more than 200 billion yuan total market. The appraisal meeting by the China Machinery Industry Federation commissioned by the National Energy Board, held in Chengdu organization. Chinese Academy of Engineering Zhen Ye Church of the research group of experts led by highly praised: "The successful development of prototype to meet the requirements of technical specifications, to fill the gap, and reached the advanced level." Sichuan Japanese machine company is currently undertaking into the national "Eleventh Five-Year" plan for nuclear science and technology support for the main pump mechanical seal of the development work is expected to be completed in 2012. Will then be formed, including the main pump mechanical seal, including a complete set of nuclear power with independent intellectual property mechanical seal technology, for China to accelerate nuclear power construction, improve energy structure, energy saving and emission reduction work will play a positive role in promoting .
