As a widely used general machinery, air compressor is used in all aspects of production. According to the different lubrication methods, it can be divided into oil-free air compressor and oil-free air compressor.
What is the difference between the two?
The operation of micro-oil screw air compressor is involved in lubricating oil.
Oil-free air compressor, as the name implies, is that the compressed air produced by it is completely oil-free; micro-oil air compressor, the compressed air produced by it is oil-containing, but the content is very low.
Whether lubricating oil is needed: oil-free air compressors do not need lubricating oil at all, while micro-oil air compressors will need lubricating oil.
2, compressed air quality: oil-free air compressor can ensure that 100 of the compressed air discharged does not contain lubricating oil, and micro-oil air compressor can not do this, so the former compressed air quality is higher.
3. Application: Micro-oil air compressor is generally used in ordinary industrial production; oil-free air compressor is generally used in food, beverage, pharmaceutical and other occasions that require very high quality of compressed air. This is mainly due to the quality of compressed air.
4, manufacturing materials and process requirements: oil-free air compressor needs to use water lubricated air compressor head, for the manufacturing materials, process requirements are higher. The micro-oil air compressor does not need to use self-lubricating materials, and the requirements for the manufacturing process are not so high.
When choosing an air compressor, we usually consider a "multiple" factor, just like preparing a grand banquet, ensuring that the amount of food and drinks is sufficient, and leaving some room just in case. Similarly, in order to ensure the air supply of the air compressor
permanent magnet variable frequency air compressor which brand is good? -- shanghai granklin group detailed air compressor products in the air compressor industry, permanent magnet frequency conversion technology because of its high efficiency, energy saving characteristics and widespread concern. In the face of numerous permanent magnets on the market
With the continuous progress of industrial technology, air compressor as an important equipment in industrial production, its performance and technology are also constantly improving. Among the many air compressors, the 0.8MPa water lubricated screw air compressor produced by Shanghai Granklin Group has excellent performance and ring
There is a lot of water in the compressed air pipeline, mainly for the following reasons: 1. **Condensed water is produced during the compression process**:-When the air is compressed, the temperature will rise, resulting in an increase in the water vapor content in the air. When the compressed air cools, this water vapor condenses into a liquid state
The size of the common air pressure in the factory depends on the specific application scenario and requirements. In general, the factory normal air pressure usually refers to atmospheric pressure, I .e. standard atmospheric pressure, the value of which is defined as 101325 Pa pascals (Pa). However, in practical applications, the actual air pressure of the factory can be
Q: What happens if the air compressor does not drain? A: The air compressor does not drain for a long time will cause the water content in the compressed gas to increase. Impact: The increase in the water content of the compressed gas will affect the quality of the gas, and the impact on the post-equipment and the production process will be greater. Yan
Class II pressure vessels are special equipment. Special equipment refers to the equipment involving life safety and high risk, including boilers, pressure vessels, pressure pipes, etc. The second type of pressure vessel is based on the pressure level of the pressure vessel, the work in the process.
Compressed air testing standard specification mainly includes the following aspects: 1. compressed air quality testing content Compressed air testing content mainly involves the content of solid particles, water and oil in compressed air. The presence of these pollutants
Q: How do I get food and beverage-grade compressed air? A: You can use a "water-lubricated air compressor" to compress and get oil-free air. shanghai granklin group is the main production of "water lubrication oil free air compressor" manufacturers, welcome at any time
The calculation of the gas volume conveyed by the powder air compressor needs to consider the material characteristics, conveying distance, pipeline parameters and process requirements, and the following are the key calculation steps and core parameter analysis: 1. the basic parameters to determine the conveying capacity (mass flow) according to the production requirements to determine the unit.
