Technical Field

[0001] The invention relates to the technical field of screw vacuum pumps, and in particular to a high-efficiency water-cooled oil-free screw vacuum pump. Background Art

[0002] The screw vacuum pump is an exhaust device that uses a pair of screws to rotate synchronously at high speed in opposite directions in the pump casing to produce suction and exhaust effects. It is an upgraded version of the oil-sealed vacuum pump and can extract gases containing a large amount of water vapor and a small amount of dust. It is widely used in domestic pharmaceutical, chemical, semiconductor and other corporate fields that have high requirements for clean vacuum.

[0003] However, in the prior art, when the existing screw vacuum pump is in use, the interior of the screw vacuum pump is generally cooled by oil cooling, which requires a large amount of oil for cooling.
