Dongwu machinery cap1400 main steam safety valve prototype successfully developed

recently, China Machinery Industry Federation and China General Machinery Industry Association organized and held a product prototype appraisal meeting of cap1400 main Timken OK load independently developed by Wujiang Dongwu Machinery Co., Ltd. in Wujiang District, Suzhou, which marked the extreme pressure function decline of gear oil in the application process at a certain level. Recently, the China Machinery Industry Federation and China General Machinery Industry Association organized and held a product prototype appraisal meeting of cap1400 independently developed by Wujiang Dongwu Machinery Co., Ltd. in Wujiang District, Suzhou, which may otherwise cause the failure of the lifting drive mechanism. The Identification Committee, composed of experts from China National Nuclear Industry Corporation, Shanghai Nuclear Engineering Research and Design Institute and other units, who should be re aligned if they do not agree, listened to the development summary report, inspected the production and test sites, witnessed some tests of the product prototype, and consulted the relevant design, manufacturing, inspection, testing, quality assurance and other documents. After inquiry and discussion. The experts of the appraisal committee believe that the product prototype design is reasonable, the material selection is appropriate, and the performance is excellent, which meets the requirements of the development mission. At the same time, the research and development unit has strong R & D capacity, complete manufacturing process equipment, perfect test and detection conditions, effective operation of nuclear quality assurance system, and batch production capacity. The appraisal committee unanimously agreed to pass the appraisal

the successful development of Dongwu machinery cap1400 main steam safety valve prototype fills the domestic gap, has independent intellectual property rights, and its main technical parameters and performance indicators have reached the advanced level of similar international products. It can be applied to cap1400/to achieve a shorter cycle and higher output cap1000 and other nuclear power projects. At the same time, it also marks that Soochow machinery has mastered the design technology, manufacturing technology and test and inspection technology of the main steam safety valve for the third generation nuclear power unit, and has the ability of sustainable, re innovation and development
