Mechanical seal leakage treatment method

The treatment method for mechanical seal leakage usually includes the following steps:

1. Regular cleaning: The mechanical seal should be cleaned after each use to remove possible contaminants and impurities.

2. Correct installation: Ensure that the installation of the mechanical seal complies with the design and manufacturer's requirements to avoid leakage caused by improper installation.

3. Avoid dry grinding: By adjusting the pump speed, flow rate and other parameters, reduce dry friction on the end face of the mechanical seal, thereby reducing the risk of wear and thermal deformation.

4. Replace the type ring: If it is found that the contact surface of the dynamic and static rings is deformed or impurities are embedded, a new type ring or auxiliary seal should be replaced in time, and appropriate repairs or improvements should be made according to the actual situation.

5. Check the verticality of the axis: If the dynamic and static rings are not perpendicular to the axis, it is necessary to check the winding of the pump shaft and correct the deviation to ensure normal contact of the sealing surface.

6. Clean up scale: For sealing problems caused by scale, it is necessary to remove scale in time to reduce the burden on the spring and restore its normal sealing performance.

7. Check the movement of the pump shaft: For the movement of the pump shaft, the problem needs to be solved by adjusting the positioning or assembly of the shaft to ensure that the mechanical seal can move stably on the shaft.

8. Replace seals: If the mechanical seal ages or wears out after long-term use, new seals should be replaced in time to maintain the sealing effect.

9. Check the auxiliary sealing material: For the problem of swelling and loss of elasticity of the auxiliary seal due to improper material, the appropriate material should be selected according to the actual working conditions and attention should be paid to maintenance. Check the operating status of the pump: Leakage when restarting after a long stop may be caused by solidification, crystallization or other physical factors of the medium near the friction pair, and needs to be checked and adjusted according to the specific situation.

To sum up, the treatment of mechanical seal leakage involves many aspects, including regular cleaning, correct installation, avoiding dry grinding, replacing rings, checking axis verticality, cleaning scale, checking pump shaft movement, replacing seals, and Check pump operation.
