Answer: (1) Fault phenomenon.
1) The fixed ring rotates;
2) The surfaces of the moving and static rings are rough, the friction surface is damaged or the friction surface is uneven;
3) The moving ring cannot float along the axial direction;
4) The spring force is insufficient or the spring force is eccentric;
5) The end face is not resistant to corrosion or high temperature;
6) The axial movement of the rotor is too large and the moving ring cannot compensate for the displacement in time;
7) The shaft vibrates severely;
8) The seal is not positioned accurately, the friction pair is not tightly attached, and the seal ring and the moving ring are not tightly attached;
9) The end cover is not fixed correctly and offset occurs.
(2) Treatment measures.
1) Replace the sealing ring to fix the static ring;
2) Improve the end surface finish, improve lubrication conditions, replace or grind the friction surface;
3) Check the spring force and whether the thrust ring is stuck;
4) Adjust or replace the spring;
5) Replace the corrosion-resistant and high-temperature resistant dynamic and static rings to solve the intermittent leakage;
6) Adjust the axial movement;
7) Stop the machine for inspection and solve the vibration problem of the shaft;
8) Check or replace the sealing surface and adjust the positioning;
9) Adjust the end cover fastening screws to be perpendicular to the shaft.
