What should be checked before installing the mechanical seal?

1. As mechanical seals for pumps are generally suitable for use in clean media without suspended particles, the newly installed pipeline system and liquid storage tank should be carefully cleaned to prevent solidification‘Body impurities enter the end face of the mechanical seal and cause the seal to fail.

2. In the medium that is easy to crystallize, the mechanical seal should be washed frequently. Before restarting after parking, clean the crystals on the mechanical seal.

3. The mechanical seal should be disassembled carefully, and it is not allowed to hit it with a hammer or iron to avoid damage to the sealing surface of the dynamic and static rings.

4. If there is dirt that cannot be removed, try to remove the dirt, wash it clean and then disassemble it to avoid damage to the sealing components.

5. Before installing the mechanical seal, check whether all sealing components are invalid or damaged, and if so, repair or replace them.

6. The relative friction sealing surface of the moving ring and the static ring should be strictly checked, and no slight scratches, bruises and other defects are allowed. All other parts, including the pump body, impeller, sealing chamber, etc., should be rinsed clean before assembly, especially the end faces of the dynamic and static rings should be carefully wiped clean with a clean, soft cloth or cotton yarn, and then coated with a layer of clean grease or motor oil.
