It’s a waste to replace it; it drops 5 drops per minute
Mechanical seals should not leak; if they are not damaged, they can be repaired and reused
For single-face mechanical seals, is there slight wear on the end faces of the stationary and rotating rings? It may not be visible to the naked eye
There are no major issues with the machine seals on our end; we fix them ourselves before using them, and the results are quite good.
This type of mechanical seal, which has already leaked, is uncomfortable to use – it doesn’t look good, the leakage rate at the site increases, and it makes it impossible to meet the 6S standards at the site； It’s uncomfortable not to have it – it’s a shame to lose it, it’s not cheap, and it’s of no use just lying around.
Actually, with water, it can be used without changing it; and if it really can’t be replaced with filler, that’s fine too
Silicon carbide for graphite – buy some grinding paste and a platform repair kit, and also get a mirror to check the end face!
The after-sales service for Dandong clones is also a headache.
