The oil-injected screw air compressor has become the new mainstream of today's air compressor development, and has unparalleled advantages compared with the piston compressor of the same power. Superior performance and reliability. The vibration is small, the noise is low, the efficiency is high, and there is no wearing parts. The precise cooperation between the main and auxiliary rotors and between the rotor and the outer casing reduces the gas return leakage and improves the efficiency; only the mutual engagement of the rotors and the reciprocating motion of the cylinders The source of vibration and noise are reduced; the unique lubrication method brings many advantages.
Due to the pressure difference generated by itself, the lubricating oil is continuously injected into the compression chamber and the bearing, simplifying the complicated mechanical structure.
The injected lubricating oil can form an oil film between the rotors, and the main rotor can directly drive the auxiliary rotor to rotate without the need for high-precision synchronous gears.
The injected lubricant increases the tightness of the compression.
The lubricating oil absorbs a large amount of heat of compression. Therefore, even if the single-stage compression ratio is as high as 16, the head can be controlled below the carbonation and deterioration temperature of the general lubricating oil, and the rotor and the casing are not generated by the difference in expansion coefficient. friction.
Lubricating oil reduces the noise generated by high frequency compression.
OVERFLY is the electric bike brand of China. Since its establishment in 2005, Overfly focus on the R&D and manufacturing of electric bike and electric scooter ever since. With years development, Overfly electric bike successfully expanded to European, North American and Oceania markets, and occupied a certain market share. In order to solve the production origin issue, and provide more options for customers, OVERFLY developed and owns two production bases, one in Yongkang, Zhejiang, and second in Taichung, Taiwan. Also established German branch for better service.
