What is the purpose of air compressor?
There are many uses for air compressors. Here is my summary, hoping to help you ~
Compressor is a kind of machinery for conveying gas and increasing gas pressure, which is widely used in chemical production. Compressor is not only essential, but also the key equipment.
After compressors increase the pressure of various gases, they have the following general purposes:
1. Compressed gas is used as power air, which can be used as power, mechanical and pneumatic tools, control instruments and automation devices after compression.
2. Compressed gas is used for refrigeration and gas separation. This gas is liquefied by compression, cooling and expansion and used for artificial refrigeration. This kind of compressor is usually called an ice maker or an ice maker. If liquefied gas is a mixed gas, the components can be separated separately in the separation device to obtain various gases with qualified purity. For example, the separation of petroleum pyrolysis gas is compressed first, and then the components are separated at different temperatures.
3. Compressed gas is used for synthesis and polymerization. In chemical industry, some gases are pressurized by compressor, which is beneficial to the synthesis and polymerization of butadiene. For example, the atmosphere and hydrogen synthesize helium, hydrogen and carbon dioxide synthesize methanol, and carbon dioxide and ammonia synthesize urea. While polyethylene is produced under high pressure.
4. The gas compressor is also used for pipeline transportation and gas bottling. Such as long-distance transportation of gas and natural gas, bottling of chlorine and carbon dioxide, etc.

What is the use of a small air compressor?
Generally, small air compressors can be used for automobile tire inflation, spray gun painting, building decoration, medical equipment applications and so on. And are used in many places. For details, you can check the brand air compressor of Fengjinba, specializing in manufacturing small oil-free air compressors with quality first.
What industries are air compressors mainly used in?
I. Power industry
Main uses: compressed air system for instrument, compressed air system for ash removal, compressed air system for miscellaneous use in factories, water treatment including boiler make-up water treatment and industrial wastewater treatment system, and also compressed air system for power of hydropower station equipment.
Second, the chemical fiber industry
Main uses: cotton spinning industry mainly uses clean compressed air as power source, which requires high oil content; Chemical fiber industry mainly uses instrument gas and suction gun gas, and printing and dyeing mainly uses power and instrument gas.
Three. light industry
1. Food and beverage: no contact, indirect contact and direct contact with gas. No contact with gas: scroll compressor can provide gas source, such as locust jar and beverage bottle cleaning. If the raw materials are stirred and fermented, the oil content is high, so it is necessary to deodorize the compressed air.
2. Pharmaceutical industry: Non-contact gas is mainly used for power execution and instrumentation. Direct contact is generally centrifugal because of large gas consumption, stable gas production and high air quality. If the gas volume is not very large, you can choose scroll machine plus post-processor or oil-free screw.
3. Cigarette rolling industry: Compressed air is the main power source other than electricity, which is generally used for silk injection machine equipment, cigarette rolling, splicing, packaging equipment, instruments, power execution, equipment cleaning, etc.
4. Rubber and plastic products: mainly used for power execution and instrument gas, and plastics are also used for bottle blowing process.
Four, metallurgical industry:
Metallurgical industry is divided into iron and steel industry and nonferrous metal smelting and manufacturing industry.
1. Iron and steel industry: power execution, instrument gas and instrument purging are the main reasons.
2. Non-ferrous metal smelting and manufacturing: mainly used for power execution, instrument gas and spraying. 5. Waterworks are mainly used for power implementation.
What is an air compressor usually used for? What role does it play?
2. Compressor lubricating oil
2. 1 rotary vane compressor
Each type of compressor has different requirements for lubricating oil. The lubricating oil of rotary vane compressor is used to lubricate the blades that slide in and out during compression. Lubricating oil is also used as a sealant between the blade and the frame, which makes gas compression possible. Generally speaking, ISO68- 150 products meet the viscosity requirements of rotary vane compressors.
2.2 Reciprocating compressor
The reciprocating compressor provides a large discharge pressure capacity from 1 bar g to 1000 bar g(4). Reciprocating compressor oil lubricates cylinders, crankcase parts, coils, pistons, valves and oil injection rods. Crankcase assembly includes crosshead bearing, crosshead joint, crosshead guide rail and crank pin. The recent refrigeration application shows that ISO 15 lubricating oil with working viscosity less than 10 cSt can provide suitable lubrication. However, according to the operation of gas molecular weight and flow pressure, the classic product of reciprocating compressor used to treat hydrocarbon gas is ISO68-680 product.
In most reciprocating compressors, one fluid is used as a lubricant for all components. Smaller reciprocating compressors use injected lubricating oil. Large units usually use oil pump system to lubricate the upper crankcase parts. Some large equipment uses two different lubricating oils, one for cylinders and the other for other parts that need lubrication. Because the cylinder lubricating oil must be stored with the gas, it must be compatible with the downward flow process. Cylinder lubricating oil can be designed to provide lubrication under special gas or operating conditions. (2)
2.3 Screw compressor
Full-screw compressor usually uses compressed hydrocarbon and production gas, and the flow pressure range is 1-25 bar g(5). They have many advantages, including improved compression efficiency, low outflow temperature, high reliability and less maintenance due to simple mechanical structure. Spiral gas compressor must have multiple functions. They lubricate the bearings, provide an adequate seal between the screw and the frame, remove heat during compression, flush any particles in the compressor, and protect the system from corrosion. The lower limit of viscosity is 10-20cSt at bearing oil supply temperature, and 5cSt at outflow condition to ensure proper sealing. The viscosity of the upper lubricating oil depends on the ability to provide enough lubricating oil for the bearing. The typical upper limit of viscosity is 30- 100 centistoke. Generally speaking, ISO68-220 lubricating oil meets the viscosity requirements of screw compressors. The exact viscosity level depends on the operating conditions and the composition of the gas stream.
Due to the closed-loop design of the system, the synthetic products are especially suitable for screw compressors (chart 1). Lubricating oil and compressed gas enter the separator. The separated oil passes through the oil cooler and then flows back to the compressor. The degradation of lubricating oil in this process will lead to compressor problems, such as bearing failure, insufficient sealing or corrosion. In many applications, the use of synthetic compressor lubricating oil can lead to efficient hydrocarbon compression and production gas (7).
Function of air compressor in engine
So as to obtain enough air and fuel for mixed combustion.
What are the main functions and uses of the air compressor?
Give me the dead Liu Lei. Baidu looked up the classification and characteristics of a lot of air compressors.
Three basic types of air compressors include:
Table tennis
rolling
Diesel engine driven centrifugal water pump
The above three types of air compressors can be further divided into:
Bare metal and complete machine
Air cooling and water cooling
Oil filling and non-oil filling
Let's briefly discuss the following three types of air compressors:
Reciprocating air compressor
Dimensions are 0.7 MPa (g)-0.72Kw and 0.028M3/min-932 Kw and 176.4M3/min.
Reciprocating air compressor is a variable displacement compressor. This kind of compressor compresses the air enclosed in a closed space one by one (reduces its volume) to increase its air pressure. The reciprocating air compressor uses the piston in the cylinder as the driving force of compression displacement to complete the above compression process.
When the compression process is completed by only one side of the piston, the reciprocating compressor is called a single-acting air compressor, and if it is completed by two heads of the piston, it is called a double-acting air compressor. There are many spring valves on each cylinder of reciprocating air compressor. Only when the pressure difference between the two sides of the valve reaches a certain value, the valve will open.
When the in-cylinder pressure is slightly lower than the intake pressure, the intake valve opens, and when the in-cylinder pressure is slightly higher than the exhaust pressure, the exhaust valve opens.
If the compression process is completed by a single cylinder or a group of single-stage cylinders, this air compressor is called a single-stage air compressor. Many practical working conditions exceed the capacity of single-stage air compressor. Compression ratio (exhaust/intake pressure) will lead to overheating of exhaust temperature or other design problems.
Many reciprocating air compressors with power exceeding 75Kw are designed as multi-stage units, and the compression process consists of two or more stages, with cooling function between stages to reduce the temperature of air entering the next stage.
There are two kinds of reciprocating air compressors: oil injection type and oil-free type, with a wide range of pressure and gas volume options.
Rotary air compressor
0.85 m3/min-85 m3/min rotary air compressor is a variable displacement compressor. The most common rotary air compressor is a single-stage oil injection screw air compressor. This compressor has two rotors in the machine cavity, through which air is compressed, and there is no valve inside. This kind of air compressor is generally oil-cooled (the cooling medium is air or water), and this oil plays a sealing role.
Because the cooling is carried out inside the air compressor, the components will not have a high temperature. Therefore, the rotary air compressor is a continuous working system and can be designed as an air-cooled or water-cooled device.
The rotary screw air compressor has the characteristics of simple structure, few wearing parts, easy maintenance and operation, and flexible installation. Rotary air compressor can be installed on any ground that can support weight.
The oil-injection two-stage rotary screw air compressor has two pairs of rotors in the main engine, and the compression process is completed by the first stage and the second stage in series. The invention has the characteristics of simple structure, flexibility and high efficiency. The two-stage rotary screw air compressor can be air-cooled, water-cooled and fully sealed.
Oil-free rotary screw air compressor adopts specially designed main engine for compression without oil injection, thus producing oil free compressor air. Oil-free rotary screw air compressor can be air-cooled and water-cooled, with the same flexibility as oil injection. As you can see, the rotary screw air compressor has air cooling, water cooling, oil injection, oil-free, single-stage and two-stage, which has a wide range of applicability in pressure, gas volume and structure.
Centrifugal air compressor
11.2m3/min-420m3/min Centrifugal air compressor is a dynamic air compressor. It completes the energy conversion through the rotating turbine, and the rotor changes the kinetic energy and pressure of the air to achieve the above conversion. The conversion from kinetic energy to pressure is realized by reducing the air velocity through a static diffuser.
Centrifugal air compressor is an oil-free air compressor. The lubricating oil of the moving gear is sealed by the shaft and the air is isolated.
Centrifugal compressor is a continuous compressor with few moving parts, which is especially suitable for oil-free atmosphere.
Centrifugal air compressor is water-cooled, and typical devices include aftercooler and all control devices ...
