70% of oil refining and chemical safety accidents are caused by seal leakage, so leakage prevention has always been a worldwide problem. A few days ago, it was learned from PetroChina Northeast Refining and Chemical Engineering Co., Ltd. that this problem has been cracked by Zhao Linyuan, an employee of the company. He presided over the mechanical seal technology transformation in the national science and technology award conference won the second prize of national science and technology progress.
Zhao Linyuan is an ordinary employee. After working, he taught himself the courses of mechanical seal design and installation, mechanical seal principle, metal materials science, process processing, etc. For more than ten years, he measured himself, drew his own drawings, and reformed the seals. In the transformation of a set of seals imported from the United States, its service life has changed from a few days to six years, while the highest foreign record is only three years, creating the highest record in the world. So far, he has successively carried out 81 localization transformations on the seals of 75 sets of imported equipment, creating a value of more than 2500 million yuan for the enterprise.
Experts believe that the transformation of mechanical seal technology means that the mechanical seal device has achieved localization and reached the world's advanced level, filling the domestic gap and ending the history of sealing devices relying on foreign imports.
