Oil-free air compressor mainly means that no lubricating oil is used in the compression chamber of the compressor for lubrication. Such compressors are commonly referred to as oil-free air compressors. Specifically:
the meaning of oil free:
"Oil-free" is used to describe a state in which no lubricating oil is used in the compression chamber of the compressor. However, this does not mean that there is no oil in the whole compressor system, because the bearings, synchronous gears and other parts of the compressor still need lubricating oil for lubrication. The key is that these lubrication parts and compression chamber between the use of effective seal for isolation, to ensure that the air in the compression chamber is not contaminated by oil.
Features of oil-free air compressor:
the resulting compressed air is cleaner and suitable for the production of oil-sensitive products such as semiconductors, pharmaceuticals and paper.
Since lubricating oil is not used, product quality problems caused by oil contamination can be avoided.
More elaborate design and manufacturing processes are usually required to ensure the operating efficiency and durability of the compressor without lubricating oil.
Application and market demand:
oil-free air compressors are widely used in areas where high cleanliness of compressed air is required, such as medical, food, electronics and other industries.
With the improvement of environmental protection and energy efficiency requirements, the market demand for oil-free air compressors is also growing.
In general, the oil-free air compressor means that no lubricating oil is used in the compression process to provide clean compressed air to meet the needs of specific industries for high-quality compressed air.
Water-lubricated oil-free air compressors and traditional air compressors have their own advantages and disadvantages. The specific choice depends on actual needs and scenarios. The advantages of water-lubricated oil-free air compressors include: oil-free pollution: because lubricating oil is not used, the quality of compressed air is avoided by lubricating oil
Oil-free and oil-free air compressors: a comparison of durability-take the water-lubricated oil-free air compressors of Granglin Group as an example. In the air compressor market, oil-free and oil-free air compressors have always been the two mainstream choices. Both have advantages and disadvantages, but in the resistance.
Variable frequency screw air compressor, the "intelligent dancer", will not keep working. It is very clever, according to our actual needs, to adjust their "dance" and "rhythm".
Parallel operation of two air compressors can significantly improve the flexibility and reliability of the air supply system, especially for scenarios where gas consumption fluctuates greatly or redundant backup is required. The following are the key steps, technical points and precautions for parallel operation: 1. the core objectives of parallel operation.
The gas production of the air compressor refers to the gas flow generated by the air compressor in a certain period of time. It is usually expressed in cubic meters per minute (m & sup3;/min) or liters per minute (L/min). The gas flow produced by the air compressor is related to the exhaust pressure and speed. Specific
In the choice of air compressor, centrifugal and screw are two common types. According to the demand of air consumption, the following are some suggestions to help you determine which type of air compressor to choose: 1. The stability and fluctuation of air consumption centrifugal air compressor:
There is still water in the air compressor after using the air source treatment device. There are many possible reasons. The following are some main factors: matching problem of cold dryer: if the processing capacity of the cold dryer equipped with the screw air compressor is less than the exhaust capacity of the air compressor, then the cold dryer may
Air compressor flow and exhaust volume are the core parameters to describe its performance, and they are both different and interrelated. The following analysis is carried out from the three dimensions of definition, theoretical relationship and actual influencing factors: 1. basic definition discrimination flow definition: unit time through empty
The efficiency of screw air compressor is generally affected by many factors, including flow size, temperature, humidity, load rate and maintenance status. In general, the efficiency of the screw air compressor is usually between 75% and 90% **. Specifically:
The frequency conversion and power frequency of the screw air compressor have their own advantages and applicable scenarios, and it is impossible to simply say which is better. Below I will compare them in detail to help you make a more informed choice. Energy saving effect: variable frequency air compressor can be based on the actual
