据国家核电技术公司{zx1}消息，世界首台第三代核电AP1000屏蔽电机主泵第三次中间试验，于美国当地时间2010年5月17日在位于宾夕法尼亚州匹兹堡市的美国科蒂斯怀特（CURTISS－WRIGHT）公司EMD主泵制造厂取得成功，向取得最终鉴定试验成功迈出了重要一步。 此次试验于当地时间5月13日正式启动，至5月17日，主泵冷态运行试验、热态性能试验、电机性能试验、转子刚度试验等试验项目全部完成。试验结果达到了设定的8个期望目标，即：惰转曲线平滑；轴承没有出现异常噪音；没有出现过度振动；推力瓦载荷探头所测数据表明推力载荷均匀分布；轴向推力载荷在推力轴承允许范围内；径向轴承所受载荷在径向轴承允许范围内；水力性能显示扬程和流量在要求范围内；压力扫描结果表明转子弯曲非常小，可接受。 EMD和西屋公司将在未来12个月内完成主泵的最终鉴定试验，以满足主泵按合同进度向我国第三代核电自主化依托项目浙江三门核电站一期工程和山东海阳核电站一期工程按期供货的进度要求。 相关专家表示，AP1000核电反应堆冷却剂循环泵要求采用立式、单级、离心式整体封闭式屏蔽电机泵，功率达到5500千瓦。 专程赴美见证该项试验的国家核电技术公司董事长王炳华指出，AP1000屏蔽电机主泵技术引进和设备制造国产化，是我国第三代核电技术引进中最关键的课题。本次中间试验取得成功，是我国第三代核电自主化依托项目核岛关键设备制造进程中实现的一项重大突破。 王炳华介绍，第三代核电AP1000屏蔽电机主泵具有更高的先进性，加大了电机功率，设计要求做到60年运行期间无需维修。作为首次应用于核电站建设的AP1000屏蔽电机主泵，需要做一系列的台架试验来验证其设计和制造性能。

According to the State Nuclear Power Technology Corporation News, the world's first third-generation AP1000 nuclear power shielding the middle third of main pump motor test, the U.S. local time May 17, 2010 in Pittsburgh, Pennsylvania United States 科蒂斯怀特 (CURTISS-WRIGHT ) EMD main pump manufacturing company to succeed, to win the final test successfully identified an important step. The experiment was local was officially launched on May 13, to May 17, the main pump cold running test, thermal performance tests, electrical performance test, the rotor stiffness tests pilot project completed. The results met expectations set eight goals, namely: the idle smooth curve; bearing no unusual noise; no excessive vibration; thrust watt load measured probe data show that the thrust load distribution; axial thrust load on thrust bearing allowable range; radial bearings in the radial bearing load suffered the extent permitted; hydraulic head and flow performance in the required display range; pressure scanning results showed that the rotor bending is very small, acceptable. EMD and Westinghouse in the next 12 months to complete the final identification of the main pump tests to meet the main pump progress under the contract to the third generation of our country relies on nuclear power projects independent of the first phase of Zhejiang Sanmen Nuclear Power Plant and Shandong Haiyang Nuclear Power Station Phase I the progress of scheduled delivery requirements. Experts said, AP1000 nuclear reactor coolant pump requires a vertical, single stage, the overall closed Canned Motor Centrifugal pumps, power to 5,500 kilowatts. Made a special trip to the United States witnessed the trial of the State Nuclear Power Technology Lines of Plastic chairman pointed out, AP1000 shielding the main pump motor technology import and localization of equipment manufacturing is the third generation nuclear power technology in China to introduce the most critical issue. The success of this pilot test, the third generation of our country relies on nuclear power projects independent of the key nuclear island equipment manufacturing process to achieve a major breakthrough. Lines of Plastic introduction, the third-generation AP1000 nuclear power shielding the main pump motor has a higher nature, increased electrical power, the design requirements to achieve 60 years of no maintenance during the operation. As the construction of the first AP1000 Nuclear Power Plant Shield used in the main pump motor, need to do a series of bench test to verify its design and manufacturing performance.
