Air compressor after years of development has been the first piston single species to screw, vane and other major types. Simple screw air compressor has a structure, reliable operation and easy operation and a series of unique advantages, due to the widespread industry attention. Currently screw compressor which can completely replace the piston compressor, and it has a lot of piston possess the advantage that it is a high speed rotary compressor displacement compressor manufacturers ranking, engaged with each other by a pair of rotors comprising helical spline, causing changes in the volume of the gas compression, in addition to the two high-speed rotation of the outer screw rotor, No other moving parts, overcoming the rotary compressor (centrifugal compressor) and reciprocating compressors (such as piston compressors) for their shortcomings, with such a small size, light weight, smooth operation, less wearing parts, high efficiency, single-stage compression ratio, energy stepless adjustment, etc., in the compressor industry has been rapid development and application. Since single-stage screw refrigeration compressor has a larger compression ratio and a wide range of capacities, empty it suitable for high, medium and low variety of conditions, especially at low temperatures conditions and variable condition situation is still high efficiency press manufacturers, the advantages are other models (such as absorption, centrifugal, etc.) do not have. Therefore, screw refrigeration compressors are widely used in various industries, the food industry air conditioning, refrigeration, beer, chemical, water, etc., is the field of refrigeration especially industrial refrigeration best models. Screw was divided in two and twin screw single screw. Twin-screw machine applications common in the market. Use air compressor oil compressor oil is used in various types of machinery to reduce friction screw compressor manufacturers, protect the liquid lubricant and processing machinery parts, mainly from the lubrication, cooling, anti-rust, cleaning, sealing and buffering effect. Lubricating oil accounted for 85% of the total lubricating materials, a wide range of brands, is now the world's annual use of about 38 million tons. Of the total lubricant requirements are: (1) anti-friction wear, reduce friction large air compressor manufacturers to conserve energy and reduce mechanical wear and tear to extend life and improve economic efficiency; (2) cooling is required to keep the friction heat removal outside the machine; (3) sealed, requiring anti-leakage, dust, blow-by gas; (4) clean rinse, wash dirt asked to exclude friction area; (5) rust corrosion, claimed the friction surface from oil deterioration or Alien erosion; (6) the kinetic energy transfer, hydraulic system and remote control motor and a continuously variable friction; (7) stress dispersion buffer, spread the load and ease the impact and shock absorption.
