1. Since
mechanical seals for pumps are generally suitable for use in clean, non-suspended particle-free media, the newly installed piping system and liquid storage tank should be carefully rinsed to prevent solid impurities from entering the end face of the mechanical seal. causing 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, so as not to damage the sealing surface of the dynamic and static rings.
4. If there is dirt that cannot be removed, try to remove the dirt, rinse it and then disassemble it, so as not to damage the sealing element.
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 frictional sealing surface of the moving ring and the static ring should be strictly checked, and any minor scratches, bruises and other defects are not 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. mechanical seal
