Considering the process production requirements of enterprises, the most common are food, medicine, school experiments and other industries. The cleanliness requirements in the compressed air process are high, and the oil-free air compressor does not contain oil in the compressed air process, ensuring high-quality air purity.
The difference between oil-free air compressor and oil air compressor is summarized as the following three points:
1. different oil content
1. Oil and no oil in the air compressor generally refer to the amount of oil in the exhaust gas of the air compressor, and the oil content of the oil machine is generally large.
The oil content of the oil-free machine is 0.01ppm, so this oil content is used to distinguish the air compressor with oil and without oil. Oil-free air compressor means that the gas compressed by the air compressor in an oil-free ambient gas does not contain oil.
Different 2. structure
1. There is no difference between the bearings of oil-free and oil-free. But from the working principle, there are obvious differences between the two. The participation of oil in the air compressor will take away the high temperature generated during the compression process of the air compressor, thereby cooling the machine.
2, oil-free compressor in the process of operation is not involved in the oil, whether it is oil-free piston machine or oil-free screw air compressor, they will produce a lot of high temperature in the process of operation.
3, oil-free air compressor relative to the oil air compressor to some extent more clean environmental protection, higher air cleanliness.
Different 3. uses
1. Oil air compressors are generally used in the steel industry, non-ferrous metal smelting and manufacturing industries.
Oil-free air compressors are generally used in industries with high quality requirements for multi-compressed air, such as food, medicine, laboratories and other industries.
In the glass manufacturing industry, the use of compressed air needs to meet specific pressure, flow, cleanliness and stability standards. The specific standard requirements are as follows: Pressure requirements General requirements: The compressed air pressure commonly used in the industry is usually between 0.7 and 1.0MPa. This pressure
The quality requirements of medical compressed air are very strict to ensure the safety and health of patients. The following is a detailed summary of the quality requirements of medical compressed air: 1. cleanliness requirements: medical compressed air must meet the cleanliness requirements, especially in
Yes, oil-free air compressors usually do not require refueling. Oil-free air compressor, as the name suggests, is an air compressor that does not use oil in the compression process. Its core components, such as screws, are specially designed and manufactured to ensure that no lubrication is required during the compression process
Among the many air compressor brands, which one to choose has become a problem faced by many users. If you are looking for an efficient, environmentally friendly and high-quality air compressor, the water-lubricated air compressor produced by Shanghai Granklin Group is undoubtedly your wise choice. granklin, shanghai
If the air compressor does not change the filter element for one year, the following results may be caused: Filter element blockage: Over time, the empty filter element will accumulate a large amount of dust, particles and other impurities, resulting in a decrease in its filtering effect or even complete blockage. Water filter may also be due to water
"30kg" usually means 30kg force (kgf), while "pressure" is usually expressed in pascals (Pa) or megapascals (MPa). The following is a detailed unit conversion process: 1. Clear unit definition kg force (kgf):1kg force is equal to the mass of 1kg
There are significant differences between screw and scroll compressors in terms of structure, working principle, performance characteristics and application fields. The following is a detailed comparison of the two: 1. working principle and structure Screw compressor Scroll compressor
The standard of industrial compressed air mainly includes the following aspects: 1. compressed air quality standard: humidity: usually requires the humidity of compressed air to be lower than 50%. Excessive humidity may cause condensation inside the equipment and affect the normal operation of the equipment. Oil content: compressed air
To obtain oil-free compressed air, the following methods and technologies can be used: 1. Definition and principle of using oil-free air compressor: oil-free air compressor does not use lubricating oil during compression, thereby avoiding lubricating oil entering Compressed air, directly output low oil or connected
The choice of power frequency or frequency conversion of air compressor depends mainly on the specific needs and application scenarios. Both have their advantages, and there is no absolute "good" or "bad". The following is a comparison of the characteristics of power frequency air compressors and variable frequency air compressors
