Leakage in the pump’s mechanical seal
Thread Content
The pump features a single-face mechanical seal; there is leakage during the hydrostatic test after the mechanical seal is installed, and there is slight axial spraying leakage when the pump shaft is rotated. What are the causes of this? The preliminary guess is that the dynamic ring auxiliary seal ring is not installed properly, or it is damaged
Additional information: The leakage point remains fixed and does not change direction as the turbine is rotated; instead, the leakage volume increases suddenly in the axial direction when the turbine reaches a certain position
It’s likely that the static ring O-ring isn’t installed properly, or the sealing ring of the static ring isn’t fitted correctly
If it’s damaged, it will leak no matter where you turn it. Check whether the sealing ring is installed properly.
I think the sealed mirror isn’t installed properly. . If the O-ring is damaged or not installed properly, it’s impossible for the disk to be repaired
It could be caused by the static ring not being installed properly
Since the direction does not change with the rotation of the shaft, it is recommended to first check whether there is an issue with the installation of the static ring seal.
It is possible that there are scratches on the surface of the static ring, and there are also issues with the hydrostatic test.
I’m writing to inform everyone that, due to the rain and low temperatures today, we haven’t opened it for inspection; we will do so when the opportunity arises. The leakage points in the pump’s operation remain at the same locations as before
The problem is likely with the static ring component
