OLIE-OVERSVØMMET SKRUEKOMPRESSORSYSTEM OG FREMGANGSMÅDE TIL MODIFICERING DERAF

An oil-flooded screw compressor system includes: a first lubricating oil supply system for supplying lubricating oil to screw parts; and a second lubricating oil supply system for supplying the lubricating oil to a bearing. The first lubricating oil supply system includes: a gas-liquid separator for introducing discharge gas of the screw compressor therein and separating the lubricating oil from the discharge gas; a first supply flow passage formed through a housing wall, having an opening on an outer surface of the housing wall and being in communication with the screw chamber; and a first supply path connected to a lubricating-oil storage region of the gas-liquid separator and to the opening of the first supply flow passage. The second lubricating oil supply system includes: a lubricating oil reservoir; a second supply flow passage formed through the housing wall, having an opening on the outer surface of the housing wall and being in communication with a bearing chamber; a second supply path connected to the lubricating oil reservoir and to the opening of the second supply flow passage; a first discharge flow passage formed through the housing wall, being in communication with the bearing chamber and having an opening on the outer surface of the housing wall; and a discharge path connected to the lubricating oil reservoir and to the opening of the first discharge flow passage.
