The pressure of compressed air used in general production workshops is almost the same, most of which are concentrated in the range of 0.6 to 0.8 MPa. You can understand that this pressure is about several times the pressure of tap water at home, which does not sound particularly large, but it is enough to drive all kinds of pneumatic tools and equipment in the workshop to work normally.
Some workshops may use a pressure of about 1.0 MPa because of the special equipment, but this situation is not much. The vast majority of ordinary production lines, 0.7 MPa is completely enough. The pressure is too low to carry the equipment, too high to waste electricity and easy to break the parts, so this range is just right.
Speaking of which, I have to mention that there is no oil and water lubrication air compressor. The air pressure produced by these two machines is very stable and will not fluctuate from high to low. Especially the water-lubricated air compressor, because the entire compression process is involved in water, the machine runs smoothly, and the output pressure fluctuation is particularly small. This is very important for equipment in the workshop that requires pressure stability.
The same is true for non-oil-water lubricated air compressors, because there is no oil interference, the air pressure output is very stable, and the pressure will not fluctuate up and down due to changes in oil temperature like traditional oil machines.
Another point is very practical. The gas equipment in the workshop actually does not require high pressure. Most pneumatic tools, air cylinders, spray guns, these things, work best in the range of 0.6 to 0.8 MPa. Therefore, when the factory selects the air compressor, it will generally be determined according to the actual needs of the equipment in the workshop, and will not blindly pursue higher pressure.
Oil-free water-lubricated air compressors have an advantage in this regard, that is, their pressure adjustment is very flexible and can be adjusted at any time according to the actual needs of the workshop, without causing excess waste.
To sum up, the compressed air pressure used in most production workshops is between 0.6 and 0.8 MPa, which can meet the needs of most gas-using equipment. The oil-free water-lubricated air compressor can not only provide this pressure stably, but also flexibly adjust it according to actual needs, which saves electricity and worry.
Air compressor, full name air compressor, is a kind of equipment used to compress gas. Air compressor and water pump structure is similar, most air compressor is reciprocating piston, rotating blade or rotating screw. Centrifugal compressors are very large applications. Its working principle is
When the air compressor is not turned on, the cold dryer usually does not work normally, but the specific operation depends on its control logic and design type. The following is a detailed analysis: the working principle of the 1. cold dryer and the core functions of the dependency relationship: Cold dryer (freeze dryer) through the refrigeration system
Granklin Group is a company that focuses on the production of water-lubricated air compressors. We understand what enterprises need. Granklin focuses on providing pure oil-free compressed air for enterprises. Oil-free air compressor is the concern of every enterprise that pays attention to product quality. The lower the oil content of compressed air, the higher the qualified rate of product quality. Especially the production of food enterprises, pharmaceutical companies and some of the higher requirements for gas production environment, are inseparable from the oil-free air compressor.
View detailsThe problem of excessive moisture in the air compressor can be dealt with in the following ways: Cooler treatment: A cooler is a device that removes the moisture in the air by condensation. The cooler of the air compressor can be replaced or maintained regularly to ensure its efficient work and reduction.
Screw air compressor host imbalance may be caused by a variety of reasons, the following are some possible solutions: check the power supply, wiring port is loose, whether the wire is tight. If the wiring port is loose or the wire is not compressed, it will cause current failure, which will cause
The filter element in the oil tank of the air compressor is usually called the oil filter element or the lubricating oil filter element. Its main function is to filter the impurities and metal particles in the lubricating oil of the air compressor, keep the lubricating oil clean, thereby extending the service life of the air compressor and ensuring its stable operation.
Under normal circumstances, the air compressor lubricating oil is not recommended to be replaced by oil, but it can be replaced in a short period of time in specific low-requirement scenarios, while the high-pressure high-power air compressor is strictly prohibited. The specific analysis is as follows: the reason why substitution is not recommended is the difference in performance requirements: air compressor oil: specially designed for air pressure
In the field of air compressors, different types of air compressors have different requirements for operating conditions. In particular, the unique working principle of the water-lubricated screw air compressor produced by Shanghai Granklin Group raises the question of whether the air compressor needs water for operation.
The application of air compressor in the mining industry is very extensive and important, mainly reflected in the following aspects: drilling and mining: in the drilling process, compressed air can drive the rotary drill bit, its role is similar to that of the jackhammer, and improves the drilling efficiency. In addition, in mining operations
Air compressor has many applications in mines, and it plays an important role in ensuring safe and efficient production in mines. The following are the main applications of air compressors in mines: to provide power for various equipment: in the process of mining, air compressors can be shearers
