Manufacturers who need compressors often cannot tell the difference between oil-free screw air compressors and oil-free scroll air compressors. In fact, there are many similarities and differences between screw machine and scroll machine. The following granklin water lubricated air compressor manufacturers compare and distinguish through working principle, detailed comparison data, advantages and application scenarios.
1. Working principle
the scroll air compressor is a movable scroll that rotates around the center of the base circle of the fixed scroll, and the two mesh with each other to realize the process of suction, compression and exhaust. (as shown below)
the screw air compressor compresses the air by means of the volume change of the tooth grooves of the male and female rotors meshing in parallel with each other in the casing to achieve the purpose of compressing the air. (as shown below)
2. Application comparison
screw air compressor is widely used in machinery, metallurgy, electronic power, chemical industry, mining, textile, transportation and many other industrial fields.
Now the water-lubricated air compressor produced by granklin Group is also widely used in hospitals, pharmaceuticals, food, beverages, wineries, laboratories and other scenarios. granklin has solved a series of air compression problems on single screw air compressors.
scroll machine is mainly used in hospitals, pharmaceuticals, food, beverages, wineries, laboratories and other places with high noise and vibration requirements, which is directly related to the characteristics of scroll machine silence and compressed air oil-free.
According to the above principle, the oil-free scroll air compressor is characterized by no metal friction in the compression chamber, low noise and long life of the compressor. However, it is obvious that the oil-free scroll air compressor has high machining accuracy and high production technology requirements.
From the above technical comparison, it can be seen that the water-lubricated air compressor produced by Granklin Group has better effect, oil-free air compression is more stable, and the maintenance of the whole machine is more convenient.
Compressed air is widely used and is the second largest power energy after electricity. Therefore, air compressors, as general equipment, are widely used in various industries. Air occupies a certain space, but it has no fixed shape and volume. In the right
Silent air compressor, is a small air compressor, large air compressor often can not control the noise, even with the addition of industrial sound insulation cotton, sound insulation cover can only be controlled within a certain range. Oil-free silent air compressor
View detailsScrew 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.
Precision filters are one of the common configurations of air compressor post-processing equipment. What is its function? Why should a filter be configured? For reference only: First of all, because the natural air sucked by the air compressor contains impurities such as moisture and dust, the air
1. After using it every day, it is necessary to check the oil level, exhaust temperature, exhaust pressure and other aspects of the screw air compressor to see if there is any abnormal situation. If the oil level is too low, it is necessary to add lubricating oil in time. In addition, there is a need
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
Single screw air compressor and twin screw air compressor difference in the world, in addition to the micro compressor, in the power with air compressor, more than 70% for the twin screw air compressor. Compared with the single screw air compressor, the performance of the new machine is not much different, mainly reflected in the performance difference after a period of use.
In recent years, the biggest black horse in the screw air compressor market (water lubricated screw air compressor) is a new type of air compressor equipment. Whether it is working principle or lubrication method, it is quite different from the traditional screw air compressor. shanghai granklin group for your detailed introduction under the oil and water lubrication screw air compressor working principle and advantages.
View detailsWhen used as a process source gas, compressed air is in direct contact with materials and food. When used as a power source, although not in direct contact with food and raw materials, but most of them are used in clean areas. Therefore, compressed air for food must use clean compressed air.
With the increase in equipment demand, the water-lubricated oil-free air compressor industry is a supporting industry in many fields, so its role is very important.
