In June 2019, a motor of Fangchenggang Nuclear Power No. 4 was leaned out for the first time. The vibration value did not reach excellent standards, but it was close to the scope of acceptance standards. Practicing the strict, cautious, detailed, and real work style of the CITIC Nuclear Group, Fangchenggang Nuclear Power Co., Ltd. requires manufacturers to deal with it. However, the mechanism of motor vibration is complicated, and the manufacturer has not been resolved after 2 years. Wu Jiong, the engineer of the Auxiliary Maintenance Director of the Mechanical Department of Guangxi Fangchenggang Nuclear Power Co., Ltd., looked in his eyes and was anxious.

In March 2021, Wu Jiong made a special trip to the manufacturer for special investigation and discussion and analysis. He carefully consulted the manufacturer's vibration processing report since 2019, reviewing the size data of key components, in the intricate inference and data, a standard beyond standards exceeded standards 0.01mm (1 wire) error aroused Wu Jiong's special attention.

Wu Jiong then pointed out the abnormalities to the manufacturer and asked to verify all the test materials, but was questioned by the manufacturer's technicians. However, Wu Jiong insisted not to let go of any details. Combining the motor design principle, structural characteristics, and rotor dynamic motion mechanism, decisively pointed out the problem, and strongly required the manufacturer to re -grind the motor shaft.

After using the gap between the shaft and the thrust head for grinding, the motor test is performed again. The effect is immediate. The vibration reaches the excellent value. The "High Vibration of the ACO Pump Group of Fangchenggang" led by Wu Jiong has won the second prize of the "Achievement Exchange Competition of the China Nuclear Industry Industry Engineering Construction Quality Management Group" in 2020.

For ten years, like a down -line work of down -to -earth, hard work, and hard work, Wu Jiong has formed his unique skills to identify the pump failure- "listening device". Whenever he receives a fault alarm, he can always accurately predict the cause of the fault through the equipment running parameters and the sound of the operation, and formulate reasonable measures to lead the technical team to repair it to resume smooth operation at the fastest speed.

Wu Jiong's work is inseparable from the word "fine". With excellent technology, he was affectionately referred to by his colleagues as "the" desperate Saburo "of the first nuclear pump maintenance group in the western region. The remaining items, more than 100 nuclear power pump equipment, and more than 300 equipment fault diagnosis.

In 2019, Guangxi Fangchenggang Nuclear Power Co., Ltd. established the "Wu Jiong Studio". Wu Jiong used this position to adhere to the solution to the first -tier production problem, the autonomy of the core equipment maintenance, the research of the innovation project and the transformation of the results, and adhere to the purpose of repairing talent training. Carry out technology research and development, lead colleagues to actively participate in innovative and creative work. In the past three years, Wu Jiong's work team has accumulated 583 items of defects and on -site technical problems, 3,140 equipment abnormal problems, and won more than 30 "Star of Safety Star" from Fangcheng Port Nuclear Power. Essence In the National Industry Vocational Skills Competition in 2021, Wu Jiong led the team to win the group championship and individual second prize in the nuclear power plant pump maintenance vocational skills competition.
