single screw air compressor with twin screw air compressor difference?
In the world, in addition to micro compressors, more than 70% of the power air compressors are twin screw air compressors. 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.
1. twin-screw is the meshing work of two rotors. The rotors are all metal parts, which are wear-resistant, and the exhaust volume will not decrease during long-term use. However, the single screw is a worm driving two star wheels, which are made of non-metallic materials and have poor wear resistance compared with metals. They are vulnerable parts in the main engine. After a period of operation, the exhaust volume declines seriously, the performance declines rapidly, and the failure rate is extremely high.
2. the single screw is three motion axis, the bearing is more than the twin screw, but also affect the life of the host.
3. in the manufacture, the twin screw has a special import equipment, processing is relatively easy, processing accuracy is easy to guarantee; and single screw on the contrary, there is no supply of imported special machine, processing difficulty, processing accuracy can not be guaranteed.
4. the life of the twin screw is longer than that of the single screw, the life of the single screw is subject to the life of the star wheel, so the life is very short.
To sum up, although the single screw has the advantages of excellent force balance and low vibration and noise in theory, it has four fatal shortcomings that are difficult to eliminate in a short period of time: first, the best type line has not been found; Second, the star wheel is worn and the exhaust volume declines seriously. Third, the structure is complex, and the difference in rigidity of moving parts makes the deformation uneven. Fourth, the accuracy of gear assembly will be reduced due to wear.
Therefore, the twin-screw air compressor is not only technically advanced, but also fully mature in practical applications, has been widely used, and the development prospects are very optimistic; and single-screw air compressor due to the existence of some decisive factors Inadequacies, its products still need to be further improved, can not be used as a mature product in the market large-scale promotion and application. In fact, the market performance of twin screw air compressors and single screw air compressors has well reflected the differences between them.
Because the screw oil-free water lubrication air compressor uses water as the lubricating medium to compress air, it provides high-quality 100 oil-free compressed air, no pollution, and the discharged water does not require special treatment, which meets the requirements of environmental protection. In the oil-free compressor market has been recognized by the majority of customer groups
View detailsShenzhen air compressor factory direct sales, Shenzhen what factory in the air compressor machine at low temperature and at room temperature, the service life of the oil filter is not the same, low temperature models will greatly slow down the carbonization of filter paper, prolong the invalid use of filter paper time; In addition, poor filter paper is invalid.
The air storage tank is a special equipment, and the air compressor manufacturer will inform the service life, which is basically 10 years. Gas storage tanks that are not more than 10 years old cannot be used. If they are more than 10 years old and have been submitted for inspection to the Quality Supervision Bureau every year, it is still acceptable.
Granklin water lubricated air compressor has a reasonable structure and an ideal force balance: both sides of the screw of the oil-free air compressor are equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also The axial force and radial force on the screw cancel each other out, making it have an ideal force balance.
Lubrication of single screw oil-free machine promoters think that the advantages of the equipment, because I do not have too much experience in this area, announced to you, only for reference. 1. The water-lubricated air compressor uses pure water for lubrication and cooling, and the internal parts combination of the body is made of stainless steel. 2. The pure water of the water-lubricated air compressor system has been circulating in the system. The system will automatically change the water at a set time to ensure the quality of the water and the operating temperature of the body is not higher than 60 degrees, so the water is not in the body. Affected and scale problems.
For the selection and configuration of air compressors, the "water lubricated air compressor" of Shanghai granklin group can be selected without oil-water separation filter and oil removal filter, because the "oil-free air compressor" produced by granklin is 100% oil-free.
Q: How to choose the pressure and gas volume of the air compressor? Granklin Air Compressor Answer: The air volume and pressure of the air compressor are based on the gas volume and gas pressure of the equipment you use, and do a good job of upgrading the production line or reserving a part of the surplus gas volume in the future.
What are the forms of oil-free air compressors? At present, oil-free air compressors are widely used. What are the forms of oil-free air compressors? First: Water-lubricated screw Water-lubricated oil-free air compressors use pure water. Therefore, their equipment is sealed during operation,
Screw air compressor is a kind of air compressor, there are two kinds of twin screw and single screw. The invention of the double is more than ten years later than the single, and the design of the double screw air compressor is more reasonable and advanced. The double overcomes the shortcomings of single imbalance and bearing vulnerability, and has the advantages of long life, low noise and more energy saving. After the technology matured in the 1980 s, its scope of application was expanding day by day.
View detailsOil-free and water-lubricated screw air compressor is a common model in the oil-free machine family. It uses pure water for lubrication, so the compressed air has high oil-free and water-free purity. Oil-free water lubrication screw air compressor in recent years in the market sales are very hot, price
