How to deal with leaks in K-type mechanical seals? UHB mortar pumps are typically equipped with K-type power seals, which seem unable to achieve zero leakage; in some cases, the leakage is quite significant. What should be done in such situations?
Leakage in K-type dynamic seals may be caused by wear or damage to the seal. The handling method is as follows: 1. First, check whether the seal is intact and undamaged. If obvious wear or damage is detected, the seal needs to be replaced promptly. 2. Before replacing the seal, you can try adjusting the degree of compression of the seal. Adjust the pressure on the seal appropriately to improve its sealing performance. But be aware that excessive pressure may cause the seal to wear out more quickly. 3. Clean and lubricate the seals. Removing the dirt around the seal and lubricating it with an appropriate lubricant can improve the sealing effect. 4. Check for any foreign objects or impurities at the sealing areas. If there are residues, they should be removed to ensure that the sealing area is clean and free of debris. 5. If the above methods still cannot resolve the leakage issue, it is recommended to contact the manufacturer or professional technicians for consultation and repair. They may provide more specific solutions or suggest replacing the seals with other types. In summary, for leakage issues with K-type dynamic seals, we should first inspect and replace the seals, and keep the sealing area clean and lubricated. If the problem remains unresolved, professional technical support can be sought. .
There’s no good solution – a few fluorine oil seals and one shaft sleeve; such seals are inherently vulnerable parts, and since they’re inexpensive, it’s better to have extra of them. If all else fails, switch to double sealing; this will significantly extend its service life.
Double seal? Are two of these shaft seals connected in series? Do I still need to modify the pump body structure?
For double-end face mechanical seals, the impeller and pump cover need to be modified based on the original pump; you should consult the pump manufacturer for details.
UHB mortar pumps can be equipped with custom modular double-end face seals, which are more durable; the cost of these seals is higher than that of K-type seals, yet they help reduce the frequency of repairs. If there is a leak in the K-type seal, replacing it with fluororubber or a sealing ring will suffice. I am the manufacturer; please contact me at: lol
Replace it frequently; ensure that the cooling water flow remains unobstructed.
