What should be done if the foam properties of the turbine lubricant are not up to standard?
Thread Content
I would like to ask, what should be done if it is found that the foam properties of the engine lubricant are not up to standard?
Are you referring to the unqualified physicochemical parameters of the oil? Was it also a phenomenon observed on-site? In the former case, oil with qualified physical and chemical properties should be replaced in accordance with the equipment’s usage requirements. If it’s the latter, then we need to look at what causes the foaming. If the reason is unknown, it’s best to send a picture of the entire device or a part of it; it’s ideal if the picture can show the device as a whole, which will facilitate discussion.

Whether there is significant stirring, such as from bearings or other stirring mechanisms; 3. Whether the operating conditions are harsh, such as high temperatures, vibrations, or impurities. Solutions: If strict standards are required, identify the problem and replace all the oil. If less stringent standards apply, filter the oil or let it settle (not recommended)
At the company’s request, the unit’s original L-TSA32 lubricant was replaced with the long-life lubricant LSE/LF. Approximately three months after operation, severe foaming was observed in the unit’s oil sight glass; samples were taken for further analysis, and it was found that the lubricant’s foaming properties did not meet the requirements, while all other parameters were normal. Since it is not practical to shut down the company’s machinery to change the lubricant, the final solution was to add an antifoaming agent to the lubricant. I wonder if any of my colleagues have dealt with such issues. What are the problems and potential risks associated with adding defoamers? What should be taken into consideration? Are there any other measures or solutions that can be adopted? I would appreciate your advice.
Run it through a vacuum oil filter – is there water in it?
I didn’t know there was something called a defoamer. Without identifying the cause of the foaming, using a defoamer will only provide temporary relief; it’s just self-delusion...
It’s a good way to remove oil and moisture
It’s not a problem of the lubricant containing water; if it did, it definitely wouldn’t work. It is the foam properties of the replaced lubricant itself that are somewhat substandard.
Is there something called a cleaning dispersant in it?
What is this? \ud83d\ude02 Is this data needed for oil analysis? What indicators of which units will be affected?
This substance functions as an additive, similar to surfactants, which help oil produce bubbles more easily
