1. The number of screws is divided into twin screw air compressors and single screw air compressors.
2. There is lubricating oil involved in the compression process. It is divided into an oil-free screw air compressor and an oil-injection screw air compressor.
Single-stage screw compressor
1. Reduce the volume of auxiliary machines and reduce the cost.
The main body of the single screw compressor is tiny. At the same time, the auxiliary part is relatively large, especially the existence of an oil and gas separator, oil cooler, and oil filter in the oil circuit system, so that the cost of the whole machine also increases accordingly.
2. Improve varieties and specifications, and develop to the poles of large capacity and small capacity.
The machining accuracy of the meshing pair of the single screw compressor is very high, so the compressor’s capacity is limited to bipolar development.
Two-stage screw compressor
Screw compressors are widely used in mining, chemical industry, power, metallurgy, construction, machinery, refrigeration, and other industrial sectors, in a wide range of capacity and mining, gradually replacing different compressors.
Screw compressors are widely used in mining, chemical industry, power, metallurgy, construction, machinery, refrigeration, and other industrial sectors, in a wide range of capacity and mining, gradually replacing different compressors.
In the future, screw compressor market share will continue to expand, especially oil-free screw air compressors and all kinds of screw process compressors, which will achieve faster development.
Air compressor is necessary industrial equipment, widely used in various industries. The stability and continuity of the machine’s working state directly affect the enterprise’s production efficiency, so the daily maintenance of the compressor is essential. The operating environment of the air compressor must be kept dry, and the surface must be kept clean. When the…
The working principle of a screw air compressor is that the Yin and Yang rotor of a pair of parallel meshing rotates in the cylinder so that the air between the rotor grooves constantly produces periodic volume changes. The atmosphere is transported from the suction side to the output side along the rotor axis, realizing…
The operation process of the screw air compressor starts from the suction process, and the gas experiences compression in the sealed volume between teeth and finally moves to the exhaust end.At both ends of the compressor body, holes of a particular shape and size are respectively opened for suction and exhaust.It is necessary to point…
In modern industrial production, compressed air is used more and more widely, and it plays an increasingly important role in improving production efficiency and product quality. Because the compressed air discharged from the air compressor contains many mixed impurities such as water vapor, oil vapor, and dust, if the compressed air containing these impurities is…
Compressed air is widely used in industry, and the cost of compressed air is a concern for every customer. The initial equipment investment is only a part of the cost, and operating expenses are the main cost of compressed air. Let’s look at it together! 1. Appropriate air compressor selection Model selection is the first…
In this article, BONA Air Compressor takes everyone to understand why the air compressor equips with a precision filter. I hope everyone can gain something after reading this article. (1) The users with strong purchasing demand for precision filters often engage in chemical painting and precision parts processing. Users in these industries have very high…
