Lubricant turns white and forms bubbles
Thread Content
Seeking help: The compressor oil (already inside the unit), which is type 46 turbine oil, is producing white foam. Is there water inside the machinery, or has the lubricating oil deteriorated?
Is the sequence for dealing with oil leakage to start with cleaning the external pipes and oil coolers, and only after that proceed to clean the interior of the unit?
Oil analysis. Reason 1: Water supply issue. Reason 2: The machine is not in operation; after adding oil, it needs to be heated and run for more than 2 hours per day. Large temperature differences between day and night can also cause water in the air to condense
Yes, external pipeline oil transportation must be successful first before internal oil transportation can take place
A laboratory analysis is needed to be convincing

First, by checking the inner surface through the sight glass, it was confirmed that no water droplets were present on its surface, which indicates that the water content in the oil is within the normal range. However, some indicators can be assessed visually, while more indicators still require laboratory testing. As for doubts regarding oil quality, oil samples should be tested regularly and the results archived. During regular inspections, it is also necessary to discharge a small amount of fluid from the bottom drain valve of the fuel tank from time to time, which helps to detect the presence of water in it. It works best, especially before the device is started. For reference.
Conduct an analysis of the oil, including its anti-emulsification time; also take oil samples and let them sit to observe the separation of oil and water

Lubricant becomes white when it contains water and forms an emulsion. However, on-site judgment requires consideration of your actual operations; you can take a sample from the bottom of the tank and let it sit for some time to check for any moisture. If no obvious moisture is present, the sample can be sent for testing (it’s best to use a sample from the bottom of the bottle). The color in this photo of the oil return sight glass indicates the oil temperature; you can check the oil temperature, as this color appears when the temperature is high due to oil leakage. If the oil sample is left for an extended period of time, it will return to its original state, and the small bubbles will also disappear
