Is it normal for there to be a lot of oil mist from the lubricant used in a newly installed centrifugal air compressor?
Thread Content
As the title suggests: For the centrifugal air compressor, I recently replaced it with 32# turbine oil as well as an oil mist filter. After using it, I noticed that the oil mist is more abundant than before, and its odor is also different. Is this phenomenon normal?
Typically, turbine oil grade 46 is used
1 The higher the number, the greater the viscosity of the oil at the same temperature; from the perspective of lubricant base oils, such oils are less likely to evaporate. 2 It is possible to detect the smell of oil mist, indicating a highly sensitive sense of smell. Low-quality lubricating oil may be mixed with cooking oil containing hot pot seasonings. Regarding the question of whether it can be used: lowering the oil supply temperature can appropriately increase the viscosity of the oil. But it is still necessary to check whether the oil film pressure generated by the low-viscosity lubricant is sufficient to support the rotating shaft, as well as whether the bearing temperature rises and vibration increases
