Air compressor main application industry
Author: www.dg-zhihe.com      Release Date:2012/11/20      View Count:16306
 


  Along with national economy
rapid development in industry, the air compressor is widely used. Air compressor due to the wide use and was known as the" general machinery". The air compressor is mainly used in which industry, and mechanical and electrical equipment company is specialized for you to answer:

By industry:

One, the chemical fiber industry

Main uses: mainly used for cotton spinning industry clean compressed air to power, higher requirements on oil content; chemical fiber industry is the main instrument air and suction silk gun with gas, and is the main motivation and instrument air.

In two, the metallurgical industry:

Metallurgical industry iron and steel industry and nonferrous metal smelting and manufacturing industry.

1, non-ferrous metal smelting and manufacturing: mainly is used for dynamic execution, instrument air, such as spraying.

In 2, the steel industry: mainly power executive, instrument air, blowing instrument.

Three, the power industry

Main application: instrument compressed air system, ash compressed air system, factory service compressed air system, water treatment consists of boiler make-up water treatment and industrial wastewater treatment system, hydropower station will be a machine is driven by compressed air system.

In four, light industry

1, rubber and plastic products: mainly used for dynamic execution, instrument air, also used for plastic bottle blowing technology.

2, food and beverage: no contact, indirect and direct contact with gas. The scroll compressor with gas source, such as cans, beverage bottle cleaning; direct contact : the case of raw materials mixing, fermentation, the oil content is high, and the need for compressed air deodorization.

In 3, the cigarette industry: compressed air is in addition to electricity outside the main power source, generally used in injection machine equipment, cigarette, and packaging equipment, but also with instrumentation, power implementation, equipment cleaning.

In 4, the pharmaceutical industry : no contact is the main power to perform and instrument air, in direct contact with air and gas for smooth, at the same time air quality is high, generally with the centrifugal; if the volume is not very big, can choose the scroll machine after the processor, or selection of oil free screw.

According to the compressed air use properties:

1, gas transportation:

For pipeline gas compressor pipeline length, depending on which determines its pressure. Send remote gas, pressure up to 30kg / square cm. Chlorine bottle pressure of 10~ 15 kg / square cm, carbon dioxide bottle pressure ranged from 50 to60 kg / cm2.

In 2, the compressed air is used for refrigeration and gas separation:

Gas is compressed, cooled, expansion and liquefaction, used for artificial refrigeration ( refrigeration and air conditioning etc.) such as ammonia or Freon compressor. The compression pressure of approximately 8 to12 kg / square cm, this type of compressor usually become" refrigerator" or" ice machine". In addition, the liquefied gas for gas mixture, the separation device, the components were separated, to obtain the qualified lip-reading various gases. Such as air liquefaction separation can get pure oxygen, nitrogen, and pure xenon, krypton, argon, helium and other rare gases.

In 3, the compressed air is used for oil hydrofining:

In the petroleum industry, using the artificial method to make hydrogen heating, pressurizing and oil, can make a cracking hydrocarbon recombination into the lighter hydrocarbons components, such as the light of the heavy oil, lubricating oil hydrogenation refining.

4, compressed air as power:

Drive a variety of pneumatic machine, pneumatic tools the discharge pressure is 7~ 8 kg / square cm ( Reference) for control, instrumentation and automation equipment, pressure of about 6kg / square cm, automatic vehicle, windows and doors opening and closing, a pressure of 2to 4kg / cm2, the pharmaceutical industry, wine industry of agitation, pressure4 kg / square cm, in jet loom weft blowing pressure of 1~ 2 kg / square cm, in large diesel engine starting pressure of 25~ 60 kg / square cm, oil well fracturing, pressure of 150kg / square cm," two law" production, the pressure of about 50 kg / square cm, high pressure blasting mining pressure of about 800kg / square cm, national defense industry in pressure compressed air as its power. The submarine 's ups and downs, torpedo shooting and driving and wreck salvage etc., with different pressure compressed air as its power.

In 5, the compressed air is used for synthesis and polymerization of;

In the chemical industry, gas is compressed to a high pressure, often enabling synthesis and polymerization of. For example, nitrogen and hydrogen in ammonia, hydrogen and carbon dioxide methanol synthesis, carbon dioxide and ammonia urea. The chemical industry, such as high-pressure polyethylene pressure up to 1500 ~3200 kg / square cm.
