The key factors affecting the air film mechanical seal are axial string movement and radial eccentricity

　2018-12-03　　

Axial string movement and radial eccentricity are the key factors affecting air film mechanical seals:

Compared with wet-running mechanical seals, gas film seals are more sensitive to changes in applied load. For this reason, it is very important to reduce all axial movement factors that cause changes in the sealing spring force. In addition, experience has shown that gas film seals should be able to withstand greater eccentricity than traditional contact mechanical seals due to their wider end face dimensions. 318 mechanical seal 　　987.html,
