Question 2: What are air compressors generally 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).
Question 3: the role of air compressor air compressor, referred to as air compressor. Air compressors are divided into piston air compressors, screw air compressors, vane air compressors and scroll air compressors. There are common piston machines and screw machines, which are widely used. Air compressor can compress air as power; Used for refrigeration and gas separation; Used for synthesis and polymerization; Used for hydrofining oil ... Air compressors are widely used in machinery, electronic chemical fiber, biomedicine, food, steel, petrochemical, new energy and other industries. Bottom line: as long as there is gas in the production process, an air compressor is needed!
Question 4: What is the air compressor for? Sliding vane compressor-a rotary variable displacement compressor, whose axial blades slide radially on a rotor eccentric to a cylindrical cylinder. The air trapped between the blades is compressed and discharged.

Question 5: What is the purpose of the 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.

Question 6: What is the function of the air compressor in the construction site? It depends on the site. Generally, air compressors provide high pressure, such as the needs of pile drivers, and small air compressors for decoration projects, such as nailing and painting.
Question 7: 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.
Question 8: What is the main principle of air compressor? What is the main purpose? Which projects are generally applicable to? Question 1: A: Air compressor is the abbreviation of air compressor and the main component of air source device. It is a device that converts the mechanical energy of prime mover (usually motor or diesel engine) into gas pressure energy, and it is a pressure generating device of compressed air. Question 2: A: The main purpose is to provide traditional air power, such as pneumatic tools, rock drills, pneumatic picks, etc. Used to provide power. Question 3: A: It is generally used in earthwork to provide power for manual drilling. It is an indispensable mechanical tool for rock excavation and hole excavation blasting.
Question 9: What role does the air compressor usually play in the factory? General chemical plants need to use air compressors, because some pneumatic valves and pneumatic instruments need instrument air, and some production links need to be stirred and mixed evenly with process air, especially in high-risk production workshops, which need nitrogen for replacement, so air compressors are essential.
