Leakage issues at the shaft seals of mixing or centrifugal pumps
Thread Content
Axial seal leaks often occur in mixers and pumps; it’s not clear what the specific structure is behind this issue or what causes the leaks – is it the material itself or the lubricating oil? I would like to ask the seniors for advice
What usually leaks is material, leaking from the sealing packing; as for the reason, consider whether the water pressure of the mechanical seal is insufficient
What usually leaks is the material, leaking from the sealing gasket. It could be insufficient pressure, wear and tear, misalignment, overheating, etc
What’s leaking is the material; the temperature must be too high. Is there cooling water available? If so, try increasing the amount of cooling water used. Another issue is that the sealing ring is damaged
Thank you, where is it hot? I see that some pumps have cooling water – what part is it used to cool?
What is seal water, huh? Is it the circulating water used for cooling, to cool the mechanical seal?
Cooling machine seal, machine seal cooling water. Pumps that handle media at high temperatures generally have mechanical seal cooling water. Shaft seals generally use sealing rings.
For cooling machine seals, condensate is generally used; direct cooling with circulating water is rarely employed. Machine seals are quite precise and have specific requirements regarding water quality
