Issues with the shaft seal of centrifugal compressors – urgent! ! !
Thread Content
Centrifugal compressors suffer from oil and gas leaking out from their bearing housings over an extended period of time, as well as significant oil leakage, due to the inability to discharge the oil and gas in their lubrication tanks in a timely manner; what harm does this cause to the compressor? Solve. . .
There’s a range hood that can be turned on; the vacuum level needs to be properly controlled, otherwise it’s possible to draw away the oil from the backup oil pump
If the positive pressure inside the bearing housing is too high, a breather can be installed at the top of the bearing housing, with its height adjusted accordingly

Gas stations typically have exhaust fans in their fuel tanks; if not, it is possible to consider installing one.
It is relatively uncommon for the bearing housing to emit oil vapor and experience significant oil leakage. It is even rarer for LZ to attribute this situation to the failure to remove the oil vapor from the tank in a timely manner and to plan to keep operating in such conditions! Not to mention that there is already an air exhaust fan in the fuel tank; even if it breaks, it’s not difficult to replace it. Has LZ thought about how the oil and gas from the fuel tank get to the bearing housing? Have you connected the fuel tank exhaust pipe to the bearing housing! It’s impossible for a lubricating oil pump to deliver gas to the bearing housing! Therefore, the failure to drain the oil and gas from the fuel tank is not directly related to the emission of oil and gas or oil leaks from the bearing housing! It is recommended that LZ promptly check whether there are any problems with the bearings themselves and the lubrication system, as well as what the bearing temperature is and what the vibration levels are Is the ventilation cap of the bearing housing blocked? Where is the oil leaking from? Check whether the oil return pipe of the bearing box is unobstructed, etc.; otherwise, serious problems will arise soon!
Could it be that the process gas is leaking?
