Novel water spraying screw rod air compressor

Abstract

The invention discloses a novel water spraying screw rod air compressor. The novel water spraying screw rod air compressor comprises a shell, a screw rod rotor, a synchronous gear, a bearing and a shaft seal, wherein an air inlet end and an air sucking end are arranged at one side of the shell; the screw rod rotor comprises a female rotor and a male rotor; the female rotor and the male rotor are horizontally arranged in the shell in parallel, and are supported on the bearing at the air inlet end; the shaft seal is positioned between the bearing and the screw rod rotor; the synchronous gear is positioned at the air sucking end of the shell, and is arranged on the screw rod rotor; and gaps are respectively formed between the female rotor and the male rotor, between the outer circle of the screw rod rotor and the shell and between the end surface of the screw rod rotor and the end surface of the shell. The novel water spraying screw rod air compressor has the advantages of good tightness, low noise, high efficiency, low rotating speed, stability, reliability and durability.

Description

technical field [0001] The invention relates to a novel water spray screw air compressor. Background technique [0002] The screw air compressor has excellent reliability, low vibration, low noise, convenient operation, few wearing parts, and high operating efficiency. In 1967, Japanese screw air compressors had already accounted for 27% of the market capacity. After continuous improvement and optimization of the market, in 1985, they had already occupied 85% of the market capacity. The market is very recognized the development of screw air compressor. The market capacity of screw air compressors in developed markets in Europe and the United States has also reached more than 80%, and the development trend continues to rise strongly. [0003] Most of the piston air compressors we used before were found to have a lot of wearing parts and poor reliability during long-term use. In order to better solve these technical problems, a screw air compressor has been produced. The m...

AI Technical Summary

Problems solved by technology

Oil-free air compressors are expensive, although the air it produces has more uses because it has no oil, but its market share is still very small, unless special industries such as medicine, electronics, food, etc. must use oil-free screw

The oil-injected screw has excellent performance, but there is still a shortcoming: oil injection lubrication and cooling are required before using the screw

Due to the combination of air and oil, high temperature and pressure, oil aging, and annual replacement of consumables also occupy a large cost. Take a 20m3 / 8kg air compressor as an example: 18 liters of oil, 5 barrels*1230=6150, 2 pieces of air filter* 650=1300, 2 oil grids*430=860, 1 set of oil and gas cores*4750=4750, totaling 13060, replaced every 4000H, twice a year for maintenance, only the cost of consumables has reached 26120 yuan
