摘要： A screw compressor (10) provided with a compressor body (11), an oil supply tank (13), an oil supply line (60), and an oil recovery line (59), wherein the screw compressor is also provided with shaft seal sections (28, 41) located on opposite sides, in the direction of shafts (26, 38), of a compression chamber (24) of a screw rotor (25) and preventing both mixing of oil in bearings (27, 39, 40) into a compression chamber (24) and leakage of process gas from the compression chamber (24), a suction-opening return line (52) for interconnecting the shaft seal section (41) on the discharge side of the compression chamber (24) and a suction opening (17) of the compressor body (11), a supply-process-gas communicating line (61) for interconnecting the suction opening (17) of the compressor body (11) and the upper part of the oil supply tank (13), and a shaft seal section (53); for dividing between the inside of the compressor body (11) and an atmospheric environment. The non-lubricated screw compressor (10, 70, 80) has the shaft seal sections (28, 41) which is inexpensive and highly reliable, which can prevent damage to the bearings (27, 39, 40) due to a reduction in the viscosity of lubricating oil, and which can prevent liquefaction of heavy hydrocarbon in a discharge system.

摘要： A screw compression apparatus (1) in which the bearing lifespan is unaffected by the properties of the target gas being compressed comprises: a screw compressor (2) in which a rotor shaft of a screw rotor (6) that is rotatably housed to compress a target gas together with a rotor lubricating fluid in a male/female interlocking arrangement in a rotor chamber (5) formed in a housing (4) is held by bearings (10, 11) arranged in bearing spaces (7, 8) formed in a housing (4) adjacently to a rotor chamber (5), and which includes shaft sealing members (13, 14) that isolate the bearing space (7, 8) from the rotor chamber (5); a lubricating fluid separating collector (3) that separates the rotor lubricating fluid from the target gas discharged by the screw compressor (2); a rotor lubricating flow channel (25) through which the rotor lubricating fluid separated by the lubricating fluid separating collector (3) is introduced into the rotor chamber (5); and a bearing lubricating system (17) for supplying a bearing lubricating fluid to the bearing space (7, 8), and cooling the bearing lubricating fluid flowing out from the bearing space (7, 8) and returning the fluid to the bearing space (7,8).
