On the job, he is a diligent and thoughtful doer; During maintenance, he pursues the ultimate "detail control", and he is the deputy team leader of Class A - Yin Liangliang.

The gasket of this regulating valve is 6 inches and weighs 600 pounds. Please pay attention when installing it. Yin Liangliang solemnly confessed. Looking up, I saw him holding a "small note" in one hand and pointing to the position of the regulating valve in the other, carefully and rigorously explaining the precautions during the installation process to the construction personnel. As the unit leader, since the major overhaul, he has set an example by always putting safety maintenance first.

During the maintenance period, the outdoor temperature usually exceeds 35 degrees, and the work clothes are wet and dry again, but this does not affect Yin Liangliang's meticulous and rigorous work style. He reinstalled several safety valves and regulating valves today, checked if the lead seals were properly installed, and recorded in detail the several maintenance operations he carried with him in his notebook. He also carefully confirmed every hot work operation, safety valve, and regulating valve. In order to ensure that there will be no leakage or dripping of the equipment in the later stage, he even climbs the tower and every position of the pipe gallery along the pipeline to confirm each manual valve.

Some people may say that the construction team can watch and install on their own, and there is no need for you to keep an eye on them. "They will confirm on their own, but as the unit leader, I am responsible for the matters I handle to ensure that everything goes smoothly," Yin Liangliang replied decisively.

Details, like a drop of water, when millions of drops converge, will become a flowing river; Details, like a star, when millions of stars gather together, they will support a brilliant starry sky. How a thing is done often depends on the handling of details. As the saying goes, 'Details determine success or failure'!

This is the second major overhaul of EO Phase II, and also the second EO Phase II overhaul I participated in when I joined Dena, "Zhu Mingrui said with a smile. He is the equipment operation engineer of the Engineering Equipment Department. During the construction of the EO Phase II plant, he came here. The EO plant has been running for 8 years, and he also grew up in Dena for 8 years.

Although witnessing the operation of EO Phase II equipment and having undergone a major overhaul, new problems and challenges may still suddenly arise. For example, in this major overhaul, during the disassembly process of the 2C-115 compressor, there was a sudden problem with the impeller being unable to be disassembled. During the step-by-step disassembly process, the professional tool that was disassembled first showed wear and tear, and the impeller had also reached the given pressure. Even so, the problem still could not be solved.

At this point, a dilemma arises: if overpressure is used for disassembly, it may damage the equipment and the damage is irreversible; If it stagnates, the next maintenance work will not be able to proceed. After careful consideration, Zhu Mingrui realized that there were still personnel from the manufacturer who could be contacted. After discussing with the maintenance unit, we quickly contacted the manufacturer.

After confirming the upper limit of equipment strength with the manufacturer, decisively reprocess professional tools and find suitable compression tools again. After a second attempt, the impeller was finally removed, allowing the compressor maintenance to continue and ensuring the quality of the critical unit maintenance and stability for the next operating cycle.

Major maintenance is a process of collaborative work among various professions, and personally, I am just an insignificant part of it. The orderly and high-quality completion of maintenance cannot be achieved without the joint efforts of every colleague in the department, "Zhu Mingrui humbly said. The engineer in front of him looked ordinary, but now he appeared so different.
