Methods for identifying mechanical seal failure in submersible pumps
Thread Content
Under normal circumstances, when the mechanical seal of a pump fails, it is easy to observe this failure. But in the case of a submersible pump, apart from insufficient flow caused by heavy leakage, what other methods can be used to detect that the seal has failed? Especially in the early stages of leakage, how can we determine this?
There are usually detection holes, which come from the pump shaft. After the leak, the high pressure came right on top
Mm-hmm, I’ve used submersible pumps before, but I’ve never seen them in action, so I’m not very clear on this aspect. Thank you!
Generally, a submersible pump has two pipes: one is the outlet and the other is the pump shaft. The shaft seal is installed on the pump shaft, right below the motor; when the seal leaks, the fluid in the pump chamber leaks into the pipeline connected to the pump shaft. Then the head will definitely exceed that of the pump itself.
Mm-hmm, I seem to understand a bit now, thank you
