Answer: A seal must be set between the oil fine separator and the end cover, and between the oil fine separator and the cylinder. Traditional sealing materials generally choose asbestos.
When compressed gas flows through the oil fine separator, static electricity will be generated due to friction. The high-pressure and high-temperature oil mist inside the oil-gas separator may burn or explode under certain conditions, so static electricity must be eliminated. Since the oil fine separator and the oil-gas separator do not contact each other, the method of staples in the asbestos gasket or metal wire to lead out static electricity was generally used in the past.
In recent years, as countries have increasingly stringent requirements for environmental protection, the use of asbestos has been increasingly restricted due to environmental pollution, and the new sealing material-flexible graphite has been more and more widely used. Flexible graphite has a good sealing effect and excellent conductivity, which can directly eliminate static electricity. Therefore, the application of flexible graphite in oil-gas separators is becoming more and more common.
