Major projects for the development of nuclear power pumps,

Recently, the major projects for the development of nuclear power pumps, valves, electrical equipment and measuring instruments have passed through the pre acceptance test of the major special office of the National Electric Power Investment Group Corporation. A series of pump and valve products developed by the research group, such as residual heat pump, CVS water pump, explosion valve, main steam isolation valve and so on, have attracted the attention of the industry.
The acceptance expert group consists of 19 experts from the China Machinery Industry Federation, the China General Machinery Industry Association, the nuclear and radiation safety center of the Ministry of environmental protection, the Chinese Academy of Sciences and the Shanghai Jiao Tong University. The group agreed that the project group had mastered the key manufacturing and test verification technology, and achieved the goals and evaluation indexes stipulated in the task contract, and realized the autonomy and localization of the equipment. The implementation of the project has adopted a combination of production, learning and research, formed a complete set of supply bases and re - innovation bases, and trained a team of talents in the design, manufacture, test and identification of the whole industry chain.
During the development of the waste heat discharge pump, the R & D personnel conquered the hydraulic model of high anti cavitation performance and the key technology of the medium inclusion air operation, and solved the problem of lubrication and cooling of the thrust bearing and the super long water guide bearing. The product has passed the performance test of the basic type test, and the severe test of the hot test, thermal shock test, aerated test and impurity test.
The project was formally established since January 2012 by the Shanghai nuclear engineering research and Design Institute in conjunction with the Shanghai kayquan pump (Group) Co., the Jiangsu sea lion Pump Manufacturing Co., Ltd., the Dalian deep blue Pump Co., Ltd., the Dalian grand valve Limited by Share Ltd, the Shanghai valve factory Limited by Share Ltd, and the Suzhou Neway valve. The company, Zhejiang three party control valve Limited by Share Ltd and other cooperation units jointly implemented a group of high level of technical achievements, applied for 80 patents (37 patents), and has authorized 48 items (10 items of invention patents).
