On May 10, the China Machinery Industry Federation organized a review meeting
of the "Hualong No.
1 nuclear power unit reactor coolant pump thrust bearing" independently developed by Harbin Electric Power Equipment Co.
, Ltd.
(hereinafter referred to as "Harbin Electric Installation") in Harbin.
The expert group unanimously agreed that the new composite bearing has completely independent intellectual property rights, filling the domestic gap and reaching the international leading level
.
The participating experts inspected the production and test site, inspected the bearing components after the test, listened carefully to the development summary report, the tribological composite material characteristics research report, the tribology research report and the evaluation report of Austrian ANDRITZ (AAG) company, and reviewed the design, manufacturing, inspection, test and other relevant documents and records
of thrust bearings.
Experts at the meeting believed that the new composite thrust bearing with independent intellectual property rights of PPESK resin matrix composite material developed by Harbin Electric Equipment has advanced design method, reasonable structure, excellent manufacturing process and material selection, and performance indicators that meet the technical requirements of all working conditions such as non-top oil inert shutdown (SBO working condition) specified in technical conditions
.
At the same time, the thrust bearing of the 300MW nuclear power main pump manufactured by the same material and process completed 2012 hours of high-load operation and 206 topless oil start-stop tests on the bearing test bench, and the performance indicators met the technical requirements
