Refined oil has a high water content
Thread Content
It’s usually quite low, around 5 ppm. Why does the water content in the refined oil rise to over 50 when the weather gets hotter? There are no changes in the parameters or operating conditions; could it be due to increased air humidity? Is the sampling bottle humid? But the bottle is sealed, right? I hope someone experienced can give me some advice!
What kind of oil is this, with such a low water content? Impressive
High humidity in the air causes water absorption during sampling or analysis, leading to an increased water content. For example, when analyzing transformer oil, the water content is reduced after thorough filtration; however, after sampling (using a glass bottle with a glass lid), transferring the sample from the device to the analysis laboratory can result in an excessively high water content, rendering it unsuitable for analysis. Additionally, if the instruments used for analysis are not placed in an environment with constant temperature and humidity, this can also lead to an increase in the water content.

Is the cooling water for your mechanical seal demineralized water?
With the operating conditions unchanged, it’s likely there’s an issue with your sampling!
Sampling issue: high air humidity in summer
As long as oil comes into contact with air, the water content in the refined oil will exceed the specified limits, under unchanged operating conditions!
