Liquid ring vacuum compressor
Thread Content
What is the reason for the leakage of liquid from the shaft seal of the non-drive end of the compressor? The sound and vibration were abnormal in the past few days. After adding grease to the non-drive end and the drive end, it became normal. Yesterday, it suddenly started leaking.
Compressed gas with liquid + mechanical seal leakage
If the mechanical seal leaks, just replace the mechanical seal. You can confirm whether it is caused by the grinding of the anti-rotation pin of the static ring gland. When disassembling, confirm whether there are two sets of mechanical seals. Ensure that when removing one mechanical seal, the radial offset of the shaft cannot be too large, otherwise the mechanical seal on the other side will be damaged. Check the fit gap before removing it.

It was speculated that the vibration caused the mechanical seal sealing surface to crack, but it did not show up at the time. After adding grease, the bearing became normal, but the hidden danger of mechanical seal damage broke out, causing sudden leakage. It is recommended to disassemble and inspect the bearings and mechanical seals. In the future, they should be maintained in strict accordance with the requirements, and checked and refueled in time.
Sihe's vacuum pump, the mechanical seal is broken:lol:lol
Just started to enter the vacuum pump industry, learn* study * :lol
