In November 2008, the company cooperated with Andritz Austria to obtain the first order of 1000 MW shaft-sealed nuclear main pump in Fuqing and Fangjiashan project bidding. Among them, the main pump motor from the motion independent research and development, manufacturing, pump parts technology from ANDRITZ company introduction, conversion.
In November 2009, the construction of a nuclear flow pump full flow test bed was launched in an all-round way. The total investment in building a full-flow test-bed of 1,000-megawatt shaft-seal-type main pump and its ancillary equipment with comprehensive, systematic, high-precision and high-intelligence standards More than 240 million yuan, construction, commissioning lasted more than 40 months. Test-bed all types of valve equipment more than 260, of which more than 30 imported equipment. Pressure pipelines more than 1,500 meters, more than 60 high-precision sensors. Test pressure 15.2MPa, temperature 293 º C, with high temperature and pressure, high precision and high integration. With the support of Andritz Austria, the construction company of the sportswear company takes the quality first in the process of transformation design, bidding and purchasing, supplier certification, document review, test verification, equipment acceptance, construction management and site optimization. , To ensure the duration of the project as the goal, to complete nearly a thousand action items, to overcome the compatibility and feasibility of test compatibility demonstration and design, Venturi flowmeter calibration, the overall system cleaning passivation, hydrostatic pressure test and many other technical difficulties, and finally get ANDRITZ And the Provincial Technical Supervision acceptance.
In April of this year, all the components of the nuclear pump were assembled on the full flow test stand of the nuclear main pump, with full-flow test conditions. Since May, a full-flow test of a 1000 MW PWR shaft-seal main pump has been completed by the assembly company and Austria's ANDRITZ Company. After 200 hours of uninterrupted and stable operation, China's first 1000 MW PWR Heap sealed main pump successfully passed the sealing function test, bearing function test, auxiliary equipment function test, hydraulic performance test, cavitation test, cooling water and seal injection water loss test, power loss and other power plant conditions Simulation test.
In the entire flow test bed debugging and testing process, design and test personnel to conduct detailed inspections, follow-up questions, study, day and night fighting, often for nearly a hundred hours continuous analysis of the problem, find out the reasons for repeated testing, to implement improvements to solve the circulatory system Local thermal deformation is not uniform, the cooling system function deviation, subsystems and lack of temperature control manometry function and lack of control procedures and other difficult problems, preliminary master the main pump full flow test technology.
Haadian Group: China's first 1000 MW PWR shaft seal main coolant pump passed the test
On May 12, for the first time, the full flow test bed for the nuclear main pump of Haidian Group's moving company was successfully implemented and the first 1000 MW PWR main coolant pump (nuclear main pump) in China was successfully completed Flow test. This shows not only the ability of Haadian Group to have a full flow test of 1000 MW PWR shaft-sealed main coolant pump units, but also marks a historic breakthrough for Haadian Group in the manufacture of nuclear power main equipment. In order to achieve this The 1000MW PWR shaft seal type main coolant pump group has laid the foundation for all localization.
