Problems solved by technology
In the prior art, the liquid spray method with only one liquid spray hole cannot realize liquid spray cooling throughout the entire compression process of the single-screw compressor, especially when the single-stage compression ratio is 17-61 under standard conditions, due to the large compression ratio , a large amount of heat is generated during the compression process, which causes the cooling liquid to be prone to oxidation, deterioration, and carbon formation, and the compressor cannot work normally, and the reliability is low

The invention is applicable to the technical field of a compressor, and discloses a single-stage medium-pressure single-screw compressor capable of being cooled through multi-point liquid spraying during the entire compression process, which comprises a shell, star-wheel components and a screw component, wherein the star-wheel component is arranged inside the shell in a rotating way and is engaged with the screw component, the quantity of the star-wheel components is two, the two star-wheel components are symmetrically arranged at two sides of the screw component, the screw component is provided with a helical groove, each star-wheel component comprises a star-wheel rotating shaft and a star-wheel plate which is engaged with the helical groove, the helical groove, the star-wheel plate and the inner side wall of the shell form a compression cavity, and the shell is provided with at least two spray holes which spray cooling liquid into the compression cavity. Due to the adoption of the single-stage medium-pressure single-screw compressor capable of being cooled through multi-point liquid spraying during the entire compression process, liquid spraying cooling during the entire compression process of the compressor can be realized, the cooling liquid can be prevented from having unfavorable phenomenon such as oxidization, deterioration, carbide and the like can be avoided, so the compressor can work normally and continuously, and the reliability of the equipment is high.
Description
technical field [0001] The invention belongs to the technical field of compressors, and in particular relates to a single-stage medium-pressure single-screw compressor with multi-point liquid spray cooling throughout the compression process. Background technique [0002] At present, the single-screw compressor consists of a cylindrical screw and two planar star wheels arranged symmetrically in the center to form a meshing pair, which is installed in a housing. The screw rod is provided with a helical groove. The spiral groove, the inner wall of the casing and the tooth top surface of the star wheel form a closed compression chamber. The power of high-speed rotation is transmitted to the spiral groove of the screw to drive the star gear teeth to rotate. With the rotation of the star gear teeth, the air enters the suction chamber from the chamfered end face of the screw, and then is closed by the star gear teeth, and compressed to the design pressure. , is discharged through...
