Oil-free compressed air refers to compressed air that does not add any oil lubrication during the compression process using an air compressor. According to ISO8573 standards, oil-free compressed air must meet certain requirements, that is, the oil content must be less than 0.01 mg/m & sup3;, reaching Class 0 level.
The working principle of oil-free air compressor mainly includes the steps of air intake, compressed air, air cooling and air discharge. In the intake stage, the air enters the compressor after being filtered by the filter screen to prevent dust, moisture, etc. from entering and causing damage to it. Then, the air entering the compressor is sucked in by the compressor extractor. Under the action of the high-speed rotating rotor, the gas is gradually compressed to a certain pressure, and heat is generated due to compression, resulting in an increase in gas temperature. In order to avoid damage to the compressor caused by overheating of the gas, a cooling system is usually provided inside the compressor to cool down the compressed high-temperature gas. Finally, the compressor internal through the outlet valve will be compressed air discharge, for industrial and civil use and other fields.
Oil-free air compressors are widely used in many industries, such as medicine, electronics, food and beverage, and chemical industry. These industries have higher requirements for air quality, and oil-free compressed air systems can meet their cleanliness standards and eliminate the possibility of product contamination by oil. In addition, the oil-free air compressor also has the advantages of low maintenance cost, environmental protection, safety and reliability. Since oil-free air compressors do not add any lubricating substances during operation, advanced material technology and manufacturing processes are needed to ensure the strength of the body and the self-lubrication inside the compression system to ensure its safety and life.
In general, oil-free compressed air is a kind of high-quality, high-cleanliness compressed air, which is suitable for industries and fields with high air quality requirements.
The selection of air compressor according to air consumption is a comprehensive decision-making process, which needs to be combined with factors such as air demand, pressure requirements, equipment characteristics and future expansibility. The following is a detailed selection guide: 1. core selection principle gas volume matching calculation formula: demand gas volume = total equipment
Oil-free air compressors do require maintenance. Although they are called "oil-free", it does not mean that they do not require any maintenance. For oil-free air compressor, regular maintenance and inspection is essential, which can ensure its efficient and safe operation, and prolong
Oil-free screw air compressor technology analysis Oil-free screw air compressor is a kind of equipment that adopts oil-free lubrication technology and realizes air compression through the meshing motion of screw and star wheel. Its core lies in the physical structure design and water lubrication system to replace the traditional lubrication.
The general water content in the atmosphere is not a fixed value, but will be affected by temperature, humidity, geographical location and climatic conditions and other factors. In the air at normal temperature and pressure, the moisture content may be several hundred to several thousand ppm(parts per mi
The standard specifications for oil-free screw air compressors cover many aspects, including air quality, energy efficiency certification, energy-saving technical requirements, and local energy efficiency standards. The following is a detailed summary of these standard specifications: 1. Air Quality Standard ISO 8573-1: This is
In the air compressor market, the comparison between power frequency and frequency conversion screw air compressor has never stopped, so which is better, power frequency and frequency conversion screw air compressor? What is the good thing about frequency conversion screw air compressor? Insert: The main area of power frequency and frequency conversion screw air compressor
As a manufacturer of water-lubricated air compressors, Granklin Group has always tried its best to meet the needs of users. In the three series of power frequency air compressors, frequency conversion air compressors and permanent magnet frequency conversion air compressors, why do water-lubricated air compressors seldom do power frequency series?
The specific power is the "power consumption report card" of the air compressor, the smaller the better. Because the water-lubricated air compressor has low water resistance, no aging, and good heat dissipation, it is naturally easy to get a smaller specific power, which saves electricity and produces clean gas. It is a "smart and clean" choice.
The relationship between the gas production of the same air compressor under different pressures can be explained by the following logic and principles, the core of which is to understand the dynamic balance between the exhaust pressure, volume flow, power consumption and efficiency of the air compressor.
The main function of the hospital compressed air station is to compress and process air to meet the air demand of various medical equipment in the hospital. Specifically, the role of the hospital compressed air station includes the following aspects: the generation and processing of 1. compressed air
