Air compressor is used in electric power, textile, steel, food, pharmaceutical, breathing, diving, fire, electronics, machinery, equipment, automobile, packaging, printing, toys, chemical, energy, glass, environmental protection, hardware, PET bottle blowing, ship, military and other aspects.
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 control 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 diesel 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 800kg/cm2, and the pressure compressed air in the national defense 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 air at different pressures.
2. Compressed gas is used for refrigeration and gas separation:
gas is compressed, cooled, expanded and liquefied, used for artificial refrigeration such as ammonia or freon compressor. 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, if the liquefied gas is mixed gas, the components can be separated separately in the separation device to obtain various gases with qualified lip reading. Such as air liquefaction can be obtained after separation of pure oxygen, pure nitrogen, and pure xenon, krypton, argon, helium and other rare gases.
3. Compressed gas for synthesis and polymerization:
in the chemical industry, gas compression to high pressure, often favorable synthesis and polymerization. For example, nitrogen hydrogen synthesis of ammonia, hydrogen and carbon dioxide synthesis of methanol, carbon dioxide and ammonia synthesis of urea. In the chemical industry, for example, the pressure of high-pressure polyethylene reaches 1500-3200kg/cm2.
4, compressed gas is difficult about oil hydrogenation refining:
in the petroleum industry, hydrogen is heated by artificial methods and reacted with oil after pressurization, which can crack the heavy parts of hydrocarbons into light components of hydrocarbons, such as the lightening of heavy oil and the hydrofining of lubricating oil.
5. Gas delivery:
compressors used for piping gas whose pressure depends on the length of the pipe. When sending remote gas, the pressure can reach 30kg/cm2. Chlorine bottling pressure is 10~15kg/square centimeter, carbon dioxide
the bottle pressure is 50-60kg/cm2.
It is best to use the original lubricating oil or the lubricating oil recommended and specified by the manufacturer. One is the oxidation resistance and thermal stability of compressor oil. For compressor oil, its oxidation resistance and thermal decomposition resistance can not only prevent oil thickening, deposition and sludge formation, but also extend the service life of compressor oil, thereby saving the high cost caused by replacement, shutdown and oil cleaning;
Shanghai Granklin Group produces and sells water-lubricated air compressors. The whole machine is made of stainless steel without lubricating oil and uses water as a lubricant. Introduction to the dry oil-free air compressor: The crankcase of the fully oil-free compressor is of a dry structure. The large connecting rod, small holes, and the front and rear main bearings of the crankshaft generally use double-port sealed grease ball bearings.
Screw air compressor operating procedures: 1. operators must be familiar with the structure, performance, working principle, operating procedures and precautions of the air compressor. 2. operators must undergo technical training and safety training and pass the examination.
How about variable frequency screw air compressor? As a water lubricated air compressor manufacturer, sales telephone number: 13918023456, I recommend purchasing variable frequency air compressor. If the gas consumption is very large, Mr. Hu recommends that you purchase permanent magnet variable frequency air compressor. Why do you do this? Screw air compressor, especially the power frequency of the machine, energy consumption is phase
The medical air compressor must be controlled within 60 decibels, and the sound of the general household air-conditioning compressor (about 55 decibels), medical staff will not feel uncomfortable working in such an environment. In view of the relatively quiet environment required by the hospital, air compressors with noise higher than 60 decibels cannot be used in hospitals.
View detailsAt present, the price of air compressors on the market is relatively transparent and there is no standard. The same technology, technology and quality of ordinary power frequency air compressor, all brands are similar, foreign brands of air compressor prices are higher. The price of the real energy-saving air compressor will be higher than that of the ordinary air compressor, which is determined by technology, quality and energy-saving effect. Granklin air compressor saves more than 30% of electricity on average, so the price will be higher, but this can be ignored, because the energy-saving part in use will soon make up for this. So sometimes high prices are an affirmation of true energy-saving technologies.
View detailsThere are many air compressor brands on the market, and the price difference is also very large, which makes buyers very vague. Granklin Group, as an air compressor manufacturer, has an understanding of the air compressor market and summarizes the following points, hoping to solve the confusion of users.
View detailsAir compressors that can be used in medical systems need to be oil-free, and the air cannot contain any grease. In the production process of medicines and medical devices, air products containing oil and gas are unqualified.
View detailsWater-lubricated oil-free air compressor company direct sales of the whole machine: the water-lubricated compressor is produced for oil-free, and the whole machine uses stainless steel components and water as lubricant, so as to eliminate gas oil and mechanical work impurities from the source. To better products, better service dedicated to the user is granklin do oil-free air compressor core values.
View detailsChina-made oil-free air compressor manufacturers, Shanghai Granklin Group, water-lubricated air compressor head is fully localized, compressed gas is 100% oil-free. Suitable for high-end industries, can match the pharmaceutical, chemical, food and other high-end manufacturing and processing industries in China. For food, medicine, textile, chemical and other industries with high gas requirements, oil-free air compressors are gradually recognized by enterprises and are widely used by more and more companies,
