1, can be used as aerodynamic
after compression, the air can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as tool replacement of machining centers.
2, can be used for gas transmission
air compressors are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling.
3. For gas synthesis and polymerization
in the chemical industry, some gases are synthesized and polymerized by increasing the pressure of compressors. Such as atmosphere and hydrogen synthesis of helium, hydrogen and carbon dioxide synthesis of methanol, carbon dioxide and ammonia synthesis of urea. And add high pressure to produce polyethylene.
4. For refrigeration and gas separation
the gas is compressed, cooled, and expanded by an air compressor and liquefied for artificial refrigeration. This type of compressor is usually called an ice maker or ice machine. If the liquefied gas is a mixed gas, each group can be separated separately in the separation device to obtain various gases with qualified purity. For example, the separation of petroleum cracking gas is first compressed, and then the components are separated separately at different temperatures.
Extended Data
the full name of the air compressor is air compressor (English: air compressor), which is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generating device for compressed air.
There are many types of air compressors, which can be divided into positive displacement compressors, reciprocating compressors, and centrifugal compressors according to their working principles.
Now commonly used air compressor piston air compressor, screw air compressor, centrifugal compressor and sliding vane air compressor, scroll air compressor.
Screw air compressor is a kind of positive displacement compressor. The compression of air is achieved by the volume change of the cogging grooves of the male and female rotors that are equally meshed with each other in the casing. The male and female rotors rotate in the casing that is precisely matched with it, so that the gas between the rotor teeth continuously produces periodic volume changes and pushes from the suction side to the discharge side along the rotor axis, completing the suction, closed transportation, Compression, exhaust and other working processes.
The scroll compressor is formed by the intermeshing of two dynamic and static scrolls with two double function equation type lines. In the work process of suction, compression, and exhaust, the static disk is fixed on the frame, and the moving disk is driven by an eccentric shaft and restricted by an anti-rotation mechanism. It rotates on a plane with a small radius around the center of the static disk base circle. The gas is sucked into the periphery of the static disc through the air filter element. With the rotation of the eccentric shaft, the gas is gradually compressed in several crescent-shaped compression chambers formed by the static and dynamic disc, and then continuously sent out by the axial hole of the central part of the static disc.
There are too many brands of oil-free air compressors. It depends on your specific needs, such as power/exhaust volume/exhaust pressure, which are all related to the price of oil-free air compressors. When buying a full oil-free air compressor, you can understand the advantages and disadvantages of different air compressor products. It is very important to choose a suitable air compressor brand. As a domestic brand, the water lubricated air compressor produced by Shanghai Granklin Group has a much lower market price than the imported brand, which is a better choice.
View detailsThe variable frequency air compressor adopts variable frequency speed regulation, the permanent magnet synchronous motor has good efficiency, high power factor, wide efficiency range, which can ensure extremely high operating efficiency and greatly improve the power saving rate in the entire speed regulation range. The permanent magnet synchronous motor (PMSM) runs with low noise. Air compressor frequency conversion
Screw air compressor as one of the essential gas supply equipment for production-oriented enterprises, how much is the price of one? I believe that many manufacturing users are more concerned about this kind of problem. Because the brand and model of the product are different, the price is not the same. When I choose
Water-lubricated single-screw air compressor is an oil-free air compressor series. Water is used as a lubricant to fundamentally solve the problem of environmental pollution caused by lubricating oil. Compared with other oil-free air compressors, it has the advantages of simple and compact structure: low speed, low vibration and noise: low exhaust temperature: high thermal efficiency: stable and reliable performance, and low specific power. It is the development trend of new oil-free oil machines.
Oil-free air compressor, Granklin Group is engaged in the production of products. As one of the main products in the air compressor manufacturing industry, oil-free air compressor has been recognized by many customers. Many customers in the purchase of air compressors are as one of the campaign goals, so what are the advantages of oil-free air compressors?
In recent years, the voice of energy saving and emission reduction in China is getting higher and higher, and the demand for energy-saving equipment is also increasing. Increasing energy conservation has also become a realistic task facing the air compressor industry. Frequency conversion air compressor is an energy-saving air compressor, its advantages are as follows: advantages: set the pressure at will, and maintain a constant pressure. Oil-free air compressor is suitable for: municipal, mining, tunnel, exploration, petroleum, wharf, shipbuilding, power plant, drilling, steel plant, subway, highway, railway, airport, factory, hospital, ship, building, communication, mining, pipeline cleaning, construction machinery and other fields.
With the rapid development of China's economy, especially the continuous improvement of the level of industrialization, the development of the air compressor industry has played a great role in promoting the gap between domestic and international advanced level is getting smaller and smaller. At present, the quality level of domestic products is constantly improving.
Different brands of low-pressure screw compressors have different prices. Take granklin air compressor as an example. A 7.5kw small oil-based air compressor is about 20,000. This belongs to the middle and high grade, and other brands are either high or low. Of course, there are smaller, 4kw, or piston machines below 7.5kw.
Contemporary screw air compressor not only uses the traditional screw, its structure, technology, but also uses a variety of materials, design and manufacture of a wide range of equipment models, the use of advanced technology developed products, so that a certain amount of screw and other materials can meet the user labor, production
Completely oil-free gas exists, and the "water-lubricated air compressor" produced by Shanghai Granklin Group is currently popular in the domestic market ". It is fully in line with the conditions of "oil-free lubrication air compressor". The air compressor head is made of stainless steel. When working, the air compressor head is filled with lubricating water. What is it like after the atmosphere is sucked in, and it is compressed and discharged. What kind.
