There are many types of air compressors. If they are divided into two types according to the lubricating oil method: one is an oil-free air compressor and the other is an oil-lubricated air compressor. These two kinds of air compressor equipment have their own advantages and disadvantages. Today we will analyze the advantages of oil-free air compressor.
Oil-free air compressor has the advantages:
1. The oil-free air compressor mainly uses water to replace oil to achieve the functions of lubrication, cooling, and sealing. The parts that need lubricating oil to lubricate the whole process are replaced by water. It can be said that the oil-free air compressor has no lubricating oil throughout the work. Participation, so the compressed air does not contain oil and the gas quality is high;
2, high quality of compressed air: oil-free air compressor because of its particularity, lubrication can replace oil with water. Coupled with the cleaning effect of water itself, it can clean some impurities and dirt during the work of the air compressor, reduce the probability of compressed air being polluted, and make the compressed gas body clean;
3. Based on the characteristics of the water lubricating oil of the oil-free air compressor, the temperature during the compression process is close to the suction temperature. Secondly, the cooling performance of water is slightly better than that of the oil, so the temperature of the entire compression environment can be controlled to make it and the suction The temperature is close, reducing the occurrence of high temperature failures;
4. Because it is water-lubricated, there is no need for oil and gas separators, oil filters and other accessories, which reduces the expenditure of this part for enterprises. At the same time, maintenance also eliminates the need to replace the oil and oil filter, simplifying the maintenance steps.
The choice of air compressor mainly follows the economy, reliability and safety. Only we follow these three guidelines to better choose air compressor.
Oil-free screw compressors can provide high-quality compressed gas to meet the needs of various fields with higher gas quality requirements such as textiles, food, packaging, biology, and air separation.
The water-lubricated air compressor produced by Shanghai Granklin Group, as an oil-free air compressor, has broken the monopoly of foreign air compressor giants on the high-end air compressor market.
Need to purchase water lubricated air compressor, oil free air compressor, screw air compressor can choose Shanghai granklin group.
The full name of the air compressor is the air compressor; a machine designed according to the working principle that the rotation of the twin screw (also known as the yin and yang rotor) causes the gas to produce volume changes. It can inhale natural air and then complete the work through several internal processes. The final discharge meets the pressure
1. The compressed air produced by oil-free air compressor is oil-free. With the improvement of users' requirements for the quality of compressed air source, oil-free air compressor is more and more widely used in some industries with high requirements for the quality of compressed air source. Although in
As a completely market-oriented industry, China's screw air compressor enterprises have experienced several rounds of ups and downs, some star enterprises "flash in the pan" out of the market.
What air compressor is good for bottle blowing machine? Each industry has different pressure requirements for air compressors, and different bottle blowing machines are the same. What air compressor is good for bottle blowing machines? Granklin air compressor manufacturers recommend using screw-type medium pressure oil-free air compressors.
View detailsMany people have heard of high-pressure air compressors, and it sounds easy to understand what it is, but it may not be possible to say it clearly. There are a lot of other people on the air compressor is not too understanding, a lot of manufacturers want to know what is the use of air compressor?
Medical air compressor mainly provides sufficient and clean air source for medical and health care equipment that needs air source. It is suitable for dental treatment equipment, oxygen generator equipment, ventilator equipment, medical pneumatic equipment, etc. The working principle of medical air compressor is a miniature oil-free air compressor. The piston air compressor is traditionally used. However, in view of the large oil content of the piston air compressor, the air cleanliness is not high.
View detailsThis depends on the brand of the air compressor, and whether it is imported or made in China. Relatively speaking, the price of the domestic 10 cubic screw air compressor is definitely a little cheaper than the imported one. 10 cubic screw air compressor price is not
The reputation of "oil-free air compressor" depends on the users who have used it. When a brand reaches a certain user base, most people say that it is easy to use and the gas supply is stable, then this "oil-free air compressor manufacturer" must be a "oil-free air compressor enterprise" with good reputation and excellent product quality ".
Permanent magnet frequency conversion air compressor has become a hot spot and bright spot in the industry due to its energy-saving and high-efficiency characteristics. The original energy-consuming air compressor on the market is gradually being replaced or replaced by permanent magnet frequency conversion air compressor, which can directly bring users 20%-40% cost savings. With the section
Speaking of how much is the water-lubricated oil-free air compressor? This problem, granklin's Shen is a professional counterpart. The main product of our Granklin Group is the water-lubricated oil-free air compressor. Under this topic, Granklin Group, as a senior enterprise in the industry, still has a little experience.
