| description | A lubricating oil filling device and a screw vacuum pump belong to the technical field of vacuum equipment. Which comprises a sealing cover (1) provided with a filling hole (5), and is characterized in that an oil filling tank (2) is hermetically covered outside the filling hole (5) of the sealing cover (1), and the top surface and the bottom surface of the oil filling tank (2) are respectively provided with a pipe thread hole (3) and an oil plug thread hole. The oil filling tank specially used for filling lubricating oil is additionally arranged outside the sealing cover, so that the lubricating oil can be filled and replaced more conveniently while the sufficient lubricating oil inside can be better ensured. During filling, filling can be conveniently conducted from the top, and when lubricating oil is replaced, waste oil in the oil filling tank can be conveniently discharged from the bottom.
