Technical Application and Prospect Analysis of Domestic Seals
At present, China's construction machinery industry has introduced a large number of host design and manufacturing technologies from developed countries, and gradually adopted the international advanced sealing system design concept and sealing device application technology. However, due to the constraints of the domestic seal industry manufacturing level, the application level of construction machinery seal technology is still lagging behind the international advanced level of about 20-25 years, and the normal working hours of the host without leakage are only about 400h, which is less than 1/10 of the international advanced level.

Breakthrough in China's Mechanical Seal Technology
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 practicing, he taught himself courses such as mechanical seal design and installation, mechanical seal principle, metal materials science, and process processing. For more than ten years, he measured and drew his own drawings to transform the seals. In the case of a set of imported equipment from the United States.
