Air compression system of water spraying screw compressor and lubrication and sealing method

Abstract

The invention discloses an air compression system of a water spraying screw compressor and a lubrication and sealing method. The air compression system comprises a screw compressor, wherein an exhaustpipeline of the screw compressor is provided with a heat exchanger; gas and condensate water in the exhaust pipeline are cooled and conveyed to a steam-water separator through the heat exchanger; cooling water obtained through separation of the steam-water separator is conveyed to the water storage tank; a macromolecule thickening agent is added into the cooling water in the water storage tank; and under driving of exhaust pressure of the compressor, the water storage tank introduces the cooling water added with the macromolecule thickening agent into a working cavity of the screw compressorthrough an output pipeline to play a role in lubrication and sealing. The invention further provides a lubrication and sealing method of the air compression system of the water spraying screw compressor. The operation is easy, leakage of the working cavity of the compressor can be reduced, the volume efficiency and the air volume of the whole compressor are improved, and meanwhile, the lubricatingeffect between rotors of the compressor is improved.

Description

technical field [0001] The invention belongs to the field of compressors, and in particular relates to an air compression system of a water-spray screw compressor and a method for lubricating and sealing it. Background technique [0002] Due to its excellent reliability, low vibration, low noise, convenient operation, few wearing parts, high operating efficiency and many other advantages, screw air compressors have been widely recognized by the market, and the development trend is still rising strongly. [0003] In key fields such as pharmaceuticals and food industries, the quality of compressed air is crucial to ensure the quality of products. In the current compressor industry, there are usually three solutions: 1. Oil-injected screw compressor with multi-stage filter device; 2. Traditional oil-free screw compressor; 3. Water-injected screw compressor. Oil-injected screw compressors have an advantage in thermal performance. Oil film lubrication can reduce leakage and prol...
