Single screw compressors and compression systems to prevent leakage of lubricants through half-loaded compressed air exhaust

摘要

An embodiment includes a housing; A drive shaft located in the horizontal direction of the center in the housing; A single screw rotor installed on the drive shaft and rotatable with respect to the horizontal axis of rotation; First and second shafts that are provided to be engaged with both left and right sides of the single screw rotor and rotate in a vertical direction as the single screw rotor rotates; First and second gate rotors installed on each of the first and second shafts and rotatable; And a bearing system installed on each of one side and the other side of each of the first and second shafts, wherein an inlet for introducing air from the outside is formed in a region corresponding to one side of the drive shaft among the upper regions of the housing, and the It is possible to provide a single screw compressor that prevents leakage of a lubricant by discharging compressed air from a half-load side in which a discharge port for discharging compressed air is formed in an area corresponding to the other side of the drive shaft of the upper area of the housing.
