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.
Determine the working pressureFirst, determine the required working pressure of the air end, add a margin of 1-2bar, and then select the pressure of the air compressor. Of course, the pipe diameter and the number of turning points will also affect the pressure loss. The larger the path diameter, the fewer turning points and 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…
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…
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…
The rising energy costs and the state’s attention to energy conservation and environmental protection have promoted the technical development of the air compressor industry. So, in the face of the present mixed situation of the air compressor industry, how to correctly choose an air compressor to reduce costs for their own production and obtain high…
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…
