Methods of improving the wear resistance and anti-friction properties of mechanical seal sealing materials

　2017-02-10　　

The increase in the hardness of mechanical seal materials will not reduce the friction. Sealing practice has proved that improving the wear resistance and anti-friction properties of mechanical seal materials should be carried out from the following aspects:

(1) Develop composite materials based on the physical-mechanical characteristics that are very in line with the ideal sealing material performance;

(2) Develop sealing materials that work under selective transfer conditions, such as metal polymer materials and lubricating alloys;

(3) Use a metal lubricant with surface active components to form a soft metal layer on the surface of the sealing material to prevent or reduce wear.　　259.html,
