Mobile screw machine has become the new mainstream of today's compressor development, with superior and reliable performance, low operating vibration, low noise, high efficiency, no wearing parts. The precise fit between the yin and yang rotors and between the rotor and the outer casing reduces the gas backflow leakage and improves the efficiency; only the rotors mesh with each other, no cylinder reciprocating motion, reducing the vibration source and noise source; unique lubrication side brings A number of advantages:
(1) With the pressure difference generated by itself, the lubricating oil is continuously injected into the compression chamber and the bearing, simplifying the complicated mechanical structure. (2) The injected lubricating oil can form an oil film between the rotors, which has lubrication and cooling effects on the equipment. The auxiliary rotor can be directly driven by the main rotor without using high-precision synchronous gears.
(3) The injected lubricating oil can increase the airtightness. Used to improve the volumetric efficiency of air compressors. From the point of view of energy saving, the energy efficiency of oil air compressors is definitely higher than that of oil-free air compressors.
(4) Lubricating oil can reduce the noise generated by high frequency compression.
(5) During use, the oil supply is misty and thoroughly mixed with the high-temperature compressed gas. The lubricating oil is repeatedly heated and cooled at a high circulation speed, and the moisture and corrosiveness in the air. The gas accelerates the oxidative deterioration of the oil. Therefore, the synthetic lubricating oil is often used, which not only can absorb a large amount of heat of compression, but also the exhaust gas temperature is not too high, and the friction between the rotor and the casing is not caused by the difference in thermal expansion coefficient.
(6) Mobile screw machine The oil and gas in the compressed air will cause a lot of troubles in use, even if it is processed by the precision filter, it can not reach the completely oil-free state, although there is Oil air compressors are more energy efficient, but precision filters add additional cost of purchase and replacement and a certain amount of pressure loss.
