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.

What are the common sense of mechanical seals

(1) the radial runout tolerance of the shaft (or shaft sleeve) where the mechanical seal is installed shall not exceed 0.04~0.06mm at most.(2) the axial movement of the rotor shall not exceed 0.3mm.(3) the runout tolerance of the positioning end face of the seal cavity combined with the seal end cover to the surface of the shaft (or shaft sleeve) shall not exceed 0.04~0.06mm at most. 2. confirmation of the seal (1) confirmation consistent with the required model.

Hydraulic Seal Installation Precautions and Storage

Hydraulic seals are the core of hydraulic equipment and guarantee the normal operation of hydraulic equipment. Therefore, the installation of hydraulic seals is very important, any errors in the installation process may affect the sealing performance, thereby affecting the normal operation of hydraulic equipment. Therefore, the operator before installation, it is necessary to understand the hydraulic seal installation precautions. In addition, the storage of hydraulic seals before installation should also be in place. Precautions for installation of hydraulic seals: 1. Check the relevant surfaces of the piston, cylinder barrel and installation guide sleeve, and ensure that they are fully clean, free of burrs and edges. 2. Installation tools shall be smooth and free

Four major mistakes in the use of asbestos-free gaskets

Expensive gaskets are not necessarily suitable. In particular, non-asbestos gaskets, non-asbestos gaskets are made of inorganic fibers or organic fibers mixed with rubber. Different fibers are mixed with different rubbers, and the application situation is very different. For example: aramid fiber and nitrile rubber mixed gasket is more general, than plant fiber and animal glue mixed into the plant fiber gasket price is expensive, but in specific conditions, such as: speed reducer, gear box and other temperature is not high, the pressure is not big, lubricating grease working conditions, the use of plant fiber gasket is economical and affordable. There is no need to choose aramid fiber nitrile rubber without asbestos board. Secondly, asbestos-free gaskets are collectively referred to as, cork rubber gaskets and expanded PTFE gaskets can be said to be asbestos-free gaskets, but the prices of the two are very different, so professional gasket manufacturers will recommend the most cost-effective and appropriate solutions according to different applications and working conditions of customers.
