Air compression system and lubrication and sealing method of water-spray screw compressor

Abstract

An air compression system of a water-sprayed screw compressor and a method for lubricating and sealing it. The air compression system includes a screw compressor. A heat exchanger is arranged on the exhaust pipeline of the screw compressor, and the gas in the exhaust pipeline is discharged through the heat exchanger. And the condensed water is cooled and sent to the steam-water separator, the cooling water separated by the steam-water separator is sent to the water storage tank, and the polymer thickener is added to the cooling water in the water storage tank, driven by the exhaust pressure of the compressor, The water storage tank passes the cooling water added with polymer thickener into the working cavity of the screw compressor through the output pipeline to lubricate and seal. The invention also provides a method for lubricating and sealing the air compression system of the water spray screw compressor. The invention is easy to operate, can reduce the leakage of the working chamber of the compressor, improve the volumetric efficiency and the gas volume of the overall compressor, and simultaneously increase the lubricating effect between the rotors of the compressor.

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...
