Mechanical seal
Thread Content
Today, a single-stage horizontal centrifugal pump was leaking at its mechanical seal while in operation. One of the equipment specialists said that the leakage would stop once the pump was shut down, as the sealing water currently creates a gap in the spring that holds the moving ring in place; when the pump stops, the spring presses the moving and stationary rings together, thus sealing them. Is that correct? It’s a bit confusing????????????
Then stop it, will the leakage decrease? \ud83d\ude04\ud83d\ude04\ud83d\ude04
The answer provided focuses a bit too much on non-scientific aspects

Try adjusting the position of the spring base + check the seal ring inside the moving ring! If it’s a new seal, it’s advisable to ask the manufacturer for the correct installation method; for an old seal, replacement should be considered. If nothing else works, feel free to contact our company at any time
If you stop, it will leak even more; he’s lying to you
This is nonsense; first, one needs to analyze where the leakage originated and then examine the possible causes. Your instructor doesn’t even understand the basic principles
Personally, I think your pump is in a vacuum system; once it starts operating, pressure builds up in the sealed chamber, and then air leaks out from the seal. When the pump stops, negative pressure develops in the sealed chamber, and air is drawn in through that seal
What he means is that it’s okay if there’s a leak; “it won’t leak once it stops.” If the machine has stopped running and the pump isn’t working, then how can there be any leakage? I don’t know; my understanding is correct√.
This laborer is truly knowledgeable; ask him next time whether mechanical seals are used to prevent leaks when the pump stops running :lol
