Air compressor is very common in our daily work, mainly used in pharmaceutical manufacturing, food processing, industrial pneumatic equipment, painting, textile, industrial and mining equipment and so on.
The German MAN company's large screw compressor MAN was founded in 1758 and is headquartered in Munich, Germany. It takes its name from the abbreviation of the company's predecessor, the aschinenfabrikugsburg-Nuremberg Machine Works (Austerborg).
It has three major business areas: trucks and buses, diesel engines and turbomachinery are all global leaders. ▲ MAN screw compressor MAN screw air compressor originated from the first oil-free screw air compressor in 1952, which is also a milestone in the history of air compressor development. The rotor diameter of MAN air compressor covers the range of 102mm to 816mm, which is the widest span on the market.
▲ MAN Screw Compressor Screw Air Compressor is an oil-injected single-stage twin-screw compressor. It adopts high-efficiency pulley (or shaft) transmission to drive the main engine to rotate for air compression. The compression chamber of the main engine is cooled and lubricated by oil injection. The air and oil mixed gas discharged from the compression chamber are separated by coarse and fine processes to separate the oil in the compressed air, and finally clean compressed air is obtained.
The core component of the screw air compressor is the compressor host, which is one of the positive displacement compressors. The air compression is achieved by the volume change of the tooth grooves of the male and female rotors that are parallel to each other in the casing. The rotor pair rotates 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, compression, and exhaust Three working processes.
Therefore, the twin screw rotor type line technology determines the screw air compressor product positioning grade.
▲The structure of screw air compressor The screw air compressor is divided into three working processes: suction, compression and exhaust.
Inhalation process: When the rotor rotates, a tooth of the male rotor continuously breaks away from a tooth slot of the female rotor, the volume between the teeth gradually expands and communicates with the suction orifice, and the gas enters the volume between the teeth through the suction orifice until the volume between the teeth When it reaches the maximum value, it is disconnected from the suction orifice, the volume between the teeth is closed, and the suction process ends. It is worth noting that the volumes between the teeth of the male and female rotors are not in communication with each other at this time.
Compression process: the rotor continues to rotate. Before the volume between the teeth of the female rotor and the male rotor is connected, the gas in the volume between the teeth of the male rotor is compressed first by the invasion of the teeth of the female rotor. After a certain angle, the volume between the teeth of the female rotor and the male rotor is connected to form a "V"-shaped volume between the teeth (primitive volume). As the two rotor teeth squeeze into each other, the primitive volume is gradually moved, the compression process of the gas is realized.
Exhaust process: due to the rotor rotation of the element volume continues to shrink, the compressed gas to the exhaust pipe, this process has continued until the volume of the minimum. With the continuous rotation of the rotor, the above-mentioned suction, compression, and exhaust processes are cyclically carried out, and each cell volume works successively, forming the working cycle of the screw refrigeration compressor.
Oil-free compressor test machine parameters, screw air compressor test contains what are the main parameters? Especially in the sale of air compressor manufacturers will test the parameters.

Shenzhen screw air compressor quotation manufacturer in screw compressor, steel cylinder
Food, medicine, textile, chemical and other industries with high gas requirements, oil-free air compressors are gradually recognized by enterprises and widely used by more and more companies.
The following points should be paid attention to during the operation of the oil injection screw air compressor: 1. When the operation occurs or abnormal vibration occurs, the machine should be stopped immediately for inspection; 2. There is pressure in the operating pipeline, and it is not possible to loosen the pipeline bolts and open unnecessary Valves, such as traps, drain valves, etc;
Generally, there are relevant installation manuals for the installation of mechanical equipment. The same is true for silent oil-free air compressors. Whether the environmental quality is good or not, the silent oil-free air compressors need to pay attention to the installation environment and whether it affects the installation effect. need in sufficient light
Shanghai granklin group is a modern enterprise specializing in the design and manufacture of air compressors. it is mainly engaged in Shanghai air compressor, variable frequency screw air compressor, permanent magnet variable frequency air compressor, screw compressor, Shanghai screw air compressor, Shanghai air compressor, oil free air compressor.
Shanghai granklin group water lubrication air compressor manufacturer, as a member of the air compressor industry, we talk about other types of air compressors, such as dry oil-free air compressors. Dry oil-free air compressor its product advantages are:
View detailsThe working principle of water-lubricated oil-free screw air compressor. Oil-free water-lubricated screw air compressor is widely used in industries requiring high-quality air sources such as medicine, food, electronics, chemical industry, packaging, etc. 10O% pure compressed air is a necessary measure to ensure the technological process and product quality. You can produce your high-grade products safely without risks.
View detailsThe oil-free screw air compressor in the factory usually needs to run all day and consume a lot of electricity. Advanced frequency conversion technology not only helps to save energy, but also makes the operation of the air compressor simple and stable. So in the choice of oil-free screw air compressor inverter should pay attention to what?
View detailsFor oil-free air compressor, most people will think that the air compressor uses air compressor oil during operation and adopts post-processing filtration to remove oil. In fact, this is one of our misunderstandings about oil-free air compressors. Air compressor oil has many functions, including cooling and lubrication. The so-called oil-free air compressor of Granklin air compressor uses water lubrication, and the compressed air is 100% oil-free.
