During the maintenance of the actual screw compressor, it was found that most of the faults complained that the oil running in the air compressor's oil and gas separator was not caused by the quality problem of oil separation.So, in addition to the oil quality problems, there are the following reasons that can lead to oil run?
1. Failure of minimum pressure valve.
2. Unqualified engine oil.
3. oil and gas separation tank design is not standard.
4. Too much refueling.
5. return oil check valve damage.
6. Improper installation of return pipe and large gas consumption.
7.Overload low pressure service, return line blocked.
