There is water in the steam compressor oil tank
Thread Content
There is one on-site centrifugal compressor for compressing steam. During a recent inspection of the oil quality, about 150 ml of oil-water mixture was discharged from the drain port (after the machine was shut down for 1 hour); the next day, after another hour of shutdown, less than 100 ml of oil-water mixture came out of the drain port. There are water droplets inside the fuel tank. The fuel tank capacity is 500L, with about 400L of fuel inside. May I ask if steam is leaking from the steam seal into the bearing box and then into the oil tank? Or some other reason? Are there any measures to identify the cause of water entering the fuel tank? Is there a solution? Thank you all.
How long has it been in use? Could it be that the poor quality of the oil is to blame, causing emulsification and the presence of water?
There are no problems with the heat exchanger in the lubricating oil system, right?
The new device has been in use for about half a year, and the oil used at first was fine
It shouldn’t be a problem with the heat exchanger; if it were leaking, there wouldn’t be so little water inside
It depends on what was missed; how can a pinhole be the same as a large hole?
There is water after shutdown; there is a high possibility of internal oil cooling leakage, a slight leak. During normal operation, the oil pressure is higher than the water pressure, which causes oil to leak into the water. To check for this issue, observe whether there are oil droplets at the cooling water outlet during normal operation; the presence of such droplets indicates an oil cooling leak.
What is the distance between the two sealing stops? Is the sealing steam turned on after the machine stops?
