What causes foam to form in the turbine oil tank?
Thread Content
The workshop’s seal oil system uses vane pumps and 32-grade turbine oil from Kunlun. But foam always forms; there are 3 units in total, and one of them doesn’t produce foam. Foaming phenomenon in other oils. What’s the reason?

The poster should check whether the liquid level is too high, or if there is air in the pipeline. We have also experienced such things
Check if there is water in the oil? Conduct physicochemical analysis of the oil.
Agree with what was said above; let’s analyze the oil sample
If the moisture content is within the acceptable range, it may be caused by additives in the lubricant.
The oil quality has been analyzed and is qualified. There are 3 seal oil pumps in the workshop, but foam appears in two of them, causing the oil to overflow from the tanks. 1 unit does not produce foam. Could it be the leaf pump?
