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.
