What causes foaming of the lubricating oil in the reciprocating compressor tank?

1. Test the viscosity, particle size, moisture content, acid value, and emulsification resistance; as long as there are no issues, that’s fine. 2. Based on my experience, it’s likely that there’s a leak in the pipeline. We’ve encountered this situation before; follow the steps mentioned above to locate the leak, conduct the tests, and if everything is satisfactory, continue operating
There is a flexible connection tube on the import side, and the outer metal casing is showing oil leakage
It’s just leaking air. If you use new oil and it passes the inspection, then it can be used with confidence. The pressure of the auxiliary oil pump shouldn’t fluctuate too much; this situation might improve once the compressor is started up and the shaft pump begins to operate
First, inspect the sample and filter out the oil; if possible, replace it directly
It is normal for the agitated thin oil to form foam; as long as it does not affect usage, foam formation is common. It's just that too much foam can cause oil leakage in the dynamic seal. The solution is to address the cause of foaming. It is most likely caused by gas flow. For reciprocating compressors, this is normal; it’s possible you haven’t been paying attention to whether there is foam in the oil level gauge.:) Take a picture to see what the foam looks like.
Check for leaks that may cause the lubricating oil to emulsify; if possible, test the quality of the oil.
