Description

Technical Field

[0001] The utility model relates to the field of screw compressors, in particular to a low-noise screw compressor. Background Art

[0002] The screw compressor is an important mechanical equipment, which mainly relies on the meshing movement of the yin and yang rotors, and uses a pair of "V"-shaped inter-tooth volumes formed by their teeth, tooth grooves and the inner wall of the casing to complete the process of lifting low-pressure gas to high-pressure gas. Its working principle is that the rotor groove is filled with gas when passing through the air intake port. When the rotor rotates, the rotor groove is closed by the casing wall to form a compression chamber. When the rotor groove is closed, lubricating oil is sprayed into the compression chamber to seal, cool and lubricate. The existing screw compressor has poor noise reduction effect. When the screw compressor is working, it generates a lot of noise, which greatly affects the working environment. Therefore, those skilled in the art provide a low-noise screw compressor to solve the problems raised in the above background technology. Utility Model Content
