What should be done if the anti-emulsification performance of turbine oil does not meet the requirements?
Thread Content
Dear teachers: I have a question. For the sampling and analysis of turbine lubricating oil, if the emulsification resistance index does not meet the requirements, are there any ways to adjust it? Can a demulsifier be added for adjustment?
I have practical experience from over 10 years ago: the demulsification time of the unit oil was not up to standard, so a demulsifier was added to the fuel tank. Of course, it is carried out under the guidance of the manufacturer. Temporary measures are not suitable for the long term.
It’s better to address this issue at its source; using demulsifiers is somewhat like trying to cover up the problem with a band-aid. The indicator for new oil procurement is satisfactory; otherwise, it is considered substandard oil. Changes in this parameter occur during use, and the cause is the presence of impurities in the oil. Such as metal powder, moisture, etc. By carefully filtering the oil, raising its temperature to remove moisture and regenerate it, it is possible to bring the oil up to standard for normal use. For reference.
Emulsifiers cannot be added; instead, the components in the lubricant should be adjusted, as there is a certain component that tends to cause emulsification, so its concentration should be reduced
Find an example. For reference only. To add it, one must use the demulsifier provided by the original manufacturer. Proportionally.
Harsh working conditions such as dust, high temperatures, and humidity are often the direct causes of a decline in the anti-emulsification properties of lubricants. Furthermore, acidic substances such as gums and asphaltenes generated by the oxidation of oils possess strong surface activity, which easily leads to the emulsification of the oils. Therefore, effective leak-proof protection for the bearing housings that contain lubricating oil is necessary. The Isomag magnetic oil seal is a good choice; it meets the API611 standards and is recommended for use.
