Air compressors are used in energy, textiles, steel, dairy products, pharmaceuticals, breathing, diving, fire protection, electronics, machinery, equipment, automobiles, packaging, printing, toys, chemicals, energy, glass, environmental protection, hardware, PET blowing Bottle, shipping, medicine, etc.
1. Compressed air as power:
A total of all kinds of pneumatic machinery are driven. The exhaust pressure of pneumatic tools is 7-8kg/cm2, which is used to adjust instruments and automatic devices. The pressure is about 6kg/cm2, the vehicle is automatic, the doors and windows are opened and closed, the pressure is 2-4kg/cm2, the stirring pressure in the pharmaceutical industry and brewing industry is 4kg/cm2, and the weft blowing pressure in the air jet loom is 1-2kg/cm2, the starting pressure of medium and large engines is 25~60kg/cm2, the pressure of oil well fracturing is 150kg/cm2, the pressure of "secondary method" oil recovery is about 50kg/cm2, and the pressure of high-pressure blasting coal mining is about It is 800kg/square centimeter, and the pressure compressed air in the aerospace industry is its power. The ups and downs of submarines, the firing and driving of torpedoes, and the salvage of sunken ships are all powered by compressed gases at different pressures.
2. Compressed gas is used for refrigeration and gas separation:
gas is liquefied by compression, cooling, expansion, and used for mechanical refrigeration such as ammonia or freon compressors. Its compression pressure is mostly 8 to 12kg/square centimeter, and this type of compressor is usually called a "refrigerator" or "ice machine". In addition to the liquefied gas, if it is a mixed gas, the components can be separated separately in the separation device to give qualified purity of various gases. Such as air liquefaction can be obtained after separation of pure oxygen, pure nitrogen, and pure xenon, krypton, argon, helium and other combustible gas.
3. Compressed gas for synthesis and polymerization:
in the chemical industry, gas compression to high pressure, often favorable synthesis and polymerization. For example, ammonia is synthesized from nitrogen and hydrogen, methanol is generated from hydrogen and carbon dioxide, and urea is synthesized from carbon dioxide and ammonia. In the chemical industry, for example, the pressure of high-pressure polyethylene reaches 1500 to 3200kg/cm2.
4, compressed gas is difficult about oil hydrogenation refining:
in the petroleum industry, hydrogen is heated by traditional methods and reacted with oil after pressurization, which can crack the heavy components of hydrocarbons into light components of hydrocarbon oxides, such as the lightness of heavy oil and the hydrogenation of lubricating oil.
5. Gas delivery:
the pressure of a compressor used to pipe air depends on the length of the pipeline. When sending remote gas, the pressure is 230kg/cm2. Chlorine bottling pressure is 10~15kg/square centimeter, carbon dioxide bottling pressure is 50~60kg/square centimeter.
Buy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
Water lubricated oil-free screw air compressor is also called water jet screw air compressor, that is, screw air compressor, there are also single screw air compressor, which means that the rotor chamber sucks in air at the same time, but also sucks in water (plays the role of lubricating the rotor and sealing)
Many enterprises in the purchase of permanent magnet variable frequency air compressor, often because of the permanent magnet variable frequency air compressor industry is not familiar with, do not know what kind of permanent magnet variable frequency air compressor brand. Generally speaking, in the domestic permanent magnet variable frequency air compressor market, there are several commonly used
A large amount of data shows that the main cost of the compressed air system is spent on the operation link, and in its life cycle, the operating cost (electricity) accounts for 78-92%. Therefore, how to tap the potential of energy consumption and improve the efficiency of energy use through fine management is the key to every enterprise.
(1) To fully meet the gas consumption of gas equipment, the maximum gas consumption should be calculated according to the type and quantity of pneumatic equipment, and the gas consumption that may be increased in the future should be included, and then the air compressor that can meet the gas supply requirements of pneumatic equipment should be selected.
The water lubricated air compressor produced by Shanghai granklin group is widely used in metallurgy, machinery manufacturing, mining, electric power, textile, petrochemical, textile and other industries. Our cases cover all provinces and cities in China. Oil-free screw air compressor
View detailsAs a special type of air compressor, Shanghai Granklin water-lubricated oil-free air compressor is widely used in laboratories, hospitals and other industries with high requirements for compressed air quality. For repair and maintenance, oil-free air compressor also has some different requirements from other air compressors. Granklin air compressor summarizes the following suggestions for your reference:
Textile processing and production process, including proofing, marking, cutting, sewing and other processes, many of which need to use compressed air. Granklin oil-free air compressors have been in the textile industry for many years, helping to provide high-quality textile products, including high-pressure series air compressors.
In some special production industries, there are relatively high requirements for the gas discharged from the screw air compressor, especially the textile enterprises and the food industry, which basically require the oil content of the compressed air to be particularly low, and basically do the oil-free compressed air. So when the screw air compressor exhaust with oil failure occurs, how do we solve this problem? Oil and gas separation core appears damaged in the operation of the screw air compressor, oil separation core appears damaged such as damage, perforation phenomenon, then it loses the role of oil and gas separation.
View detailsSingle screw air compressor in the selection process is often in order to purchase oil-free air compressor, so in Shanghai to do single screw compressor and oil-free air compressor industry to do better is which? "Shanghai Granklin Group" in the water lubrication oil-free air compressor research and development, production, sales, is a comprehensive production of air compressor enterprises.
