Oil-free screw air compressors are divided into two types, one is a dry oil-free screw air compressor, and the other is a water lubricated oil-free screw air compressor.
1. dry oil-free screw air compressor is also called oil-free screw air compressor, mostly twin screw air compressor, which means that only air is absorbed in the rotor, and the lubrication and sealing of the rotor are carried out by brushing the coating on the surface of the rotor teeth. The power range of dry screw air compressors sold in China is generally 15-900kw.
① There are two kinds of coatings, one is Teflon with general performance, and the other is a lot of molybdenum disulfide. No matter which one of the above, it has a service life and has a high requirement for water. Therefore, this kind of oil-free screw machine needs to rotate the machine frequently when not in use, so as to avoid the machine from being stuck due to the long-term immobility of the main machine. The frequent occurrence of host card failure is caused by such reasons. The main engine exhaust temperature is very high, the main engine exhaust temperature of the general oil-free screw machine can reach 180 +, the general factory will do some protective measures before leaving the factory, but in the operation or pay special attention to high temperature parts, so as not to cause burns and even fire danger.
At present, except for the oil-free mainframe maintenance proposed by IR, other manufacturers require direct replacement of the mainframe, and the cost of replacing the mainframe is very high.
2. water-lubricated oil-free screw air compressor is also called water-jet screw air compressor, that is, screw air compressor, there are also twin-screw air compressors, which means that while air is sucked in in the rotor chamber, water is also sucked in (the role of lubricating the rotor and sealing) to mix water and air and compress it.
① Water-lubricated oil-free air compressor is generally screw air compressor, screw water-lubricated oil-free air compressor is characterized by the use of water as a compressor lubrication medium is water, water-based as a seal, completely oil-free, pure oil-free compressed air, completely changed the production environment of some industries.
Because it is to the compression cavity spray water, the temperature is only about 40-50 degrees, constant temperature compression, volume efficiency is higher, than the dry oil-free screw air compressor efficiency increased by 15%.
The maintenance cost of oil-free water lubrication screw air compressor is low, only need to replace the water, water filter, air filter.
Water lubricated oil-free screw air compressor brand which? The market's numerous water lubricated oil-free screw air compressor merchants make many customers dazzled, really want to pick out an efficient, high-quality, affordable water lubricated oil-free screw air compressor in a short period of time is really not an easy thing, especially for many of the first time to buy water lubricated oil-free screw air compressor customers, the first time to buy oil-free screw air compressor is more.
Although the saying goes: foreign river chanting, but from the right time, right place, with right people. and other aspects, the local oil-free screw air compressor has a more competitive advantage. Which domestic oil-free screw air compressor? First of all, we have to ask, which domestic water-lubricated oil-free screw air compressor brands? At present, China's enterprises producing water-lubricated screw air compressors are doing relatively well, and the Granklin air compressor produced by Shanghai Granklin Group has a good reputation.
Customers have the most say, users have the most right to defend. Product quality is the most important, and corporate reputation accounts for a large proportion. This is also the reference standard for customers when selecting oil-free screw air compressors. From the product quality, corporate reputation, market evaluation and other aspects for reference, Shanghai Granklin Group is an enterprise specializing in lubricating screw air compressors. The water-lubricated screw air compressors we produce are 100% oil-free.
The single screw water lubricated air compressor uses pure water for lubrication and cooling, and the internal parts combination of the body is made of special material medical grade stainless steel, which will never corrode. Dry oil-free air compressor still depends on lubricating oil to cool, the body will produce oil smell.
Screw air compressor water cooling components include cylinder, intercooler, air compressor after cooler and lubricating oil cooler, etc. Its normal operation is closely related to these components. So, screw air compressor found that the water how to do? 1, gas
There are so many domestic air compressor manufacturers, and the number is large. Before purchasing, it is best to look at the factory scale, production capacity, and various certifications and user cases of the product, and evaluate whether the air compressor manufacturer can meet its own needs.
View detailsThe reasons why the air compressor does not pump air are as follows: it has good environmental adaptability, and the operating cost is economical and the energy-saving effect is excellent. 1. The loose pressure valve of the air compressor is stuck, and the valve plate is deformed or broken. 2. Excessive carbon deposits at the inlet and exhaust ports. 3. No intake valve
Many people are familiar with air compressors, but it is not clear why a jar is used for what it is. The gas tank, as the name suggests, is a tank used to store gas. But its role is not only to store gas, the following is to give
In some special production industries, there are relatively high requirements for the gas discharged from the screw air compressor, especially the textile enterprises and the food industry, which basically require the oil content of the compressed air to be particularly low, and basically do the oil-free compressed air. So when the screw air compressor exhaust with oil failure occurs, how do we solve this problem? Oil and gas separation core appears damaged in the operation of the screw air compressor, oil separation core appears damaged such as damage, perforation phenomenon, then it loses the role of oil and gas separation.
View detailsThe competitiveness of domestic air compressors in the global market has become stronger and stronger in recent years, thanks to the upgrading of the entire domestic industry. In the past like to buy imported air compressor, different times more and more enterprises began to choose to buy domestic air compressor.
To purchase air compressor products, first you have to learn to calculate an account, service life, after-sales air compressor, whether there is a manufacturer to provide technical support. It takes a long time to purchase an air compressor. If you spend hundreds of thousands of dollars to purchase the air compressor, it will take only 2 years to have various problems.

Choosing the right model can not only greatly reduce the purchase cost of the high-air compressor, but also
Why does the compressed gas of the screw air compressor produce water? How can we efficiently remove the moisture in the compressed gas of the screw air compressor? Is there really an oil-free and water-free screw air compressor? People in the workshop see this question. As a member of the air compressor industry, it is more reasonable for us to answer this question.
