Air compressors can be divided into oil-containing air compressors, micro-oil air compressors and oil-free air compressors according to whether they contain oil.
Oil-free air compressors usually do not contain any oil. Oil-free air compressors are virtually oil-free. The air compressor lubricated with resin material is a real oil-free air compressor. Typical oil-free air compressors have very little oil content. Oil and oil-free in air compressors generally refer to the oil content in the gas discharged from the air compressor exhaust port. Under normal circumstances, the oil content of the oil machine is large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, the oil content is used to distinguish between oil and no oil in the air compressor. There is also an oil-free air compressor, which does not use oil lubrication, but uses resin material lubrication. Therefore, the final exhaust gas is oil-free and is called an oil-free air compressor.
Micro-oil air compressor, air compressor for internal degreasing, oil content ≤ 0.1mg/m3. Compared with oil-free air compressor, the cost is cheap, and can meet the needs of customers, there is a certain market demand.
The oil content standard is the value measured under standard working conditions, and the higher the temperature of use and operation. Generally, if the oil content of the air outlet marked by each brand does not exceed 5ppm, the separation method and material designed by each manufacturer of the oil-containing air compressor will affect the oil content. The standards implemented by each manufacturer of the oil-injection screw air compressor will be different below 30ppm.
Medical compressed air gas oil content in the European Pharmacopoeia must be ≤ 0.1mg/m3.
In the air compressor system, no lubricating oil is added, pure water is used for lubrication, and no lubricating oil is involved in the operation of the air compressor. Therefore, the compressed air has no lubricating oil, so it is called an oil-free air compressor.
In the air compressor system, lubricating oil is involved in the operation of the air compressor, but the lubricating oil is isolated from the compression zone by means of complete isolation. The lubricating oil is only responsible for the lubrication protection of the bearing and does not participate in the compression.
The drainage interval of the gas storage tank shall be determined according to the humidity of the gas environment, the operation time of the equipment, the quality requirements of compressed air and other factors. There is no fixed standard, but the following methods can be used to determine and formulate a reasonable drainage plan: 1. the core factors affecting the drainage frequency
In the textile industry, a field with extremely high air quality requirements, it is very important to choose a suitable oil-free air compressor. The water-lubricated oil-free air compressor produced by Shanghai Granklin Group is the ideal choice to meet this demand. Granklin Group, with its deep
Oil-free air compressors and oil-free air compressors have their own characteristics in terms of durability, and there is no absolute difference between advantages and disadvantages. The specific durability depends on a variety of factors, including equipment quality, use environment, maintenance, etc. Durability of oil-free air compressor Material and structure: oil-free air compressor
The food industry with large demand for air compressors mainly includes baked goods, beverage production, dairy processing, snack manufacturing and fermented food. The demand for air compressors in these industries is concentrated in oil-free, stable gas supply and energy saving. The specific analysis is as follows: 1. baking
The water-lubricated air compressor has a reasonable structure and ideal force balance: both sides of the screw of the oil-free air compressor are equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also uses the screw The axial force and radial force also cancel each other out, so that
"Air compressor plant with oil" and "air compressor plant without oil" refer to whether the air compressor uses lubricating oil during operation. Traditional air compressors usually use lubricating oil to lubricate and cool the various parts of the compressor
The moisture filtration in the air compressor is an important process, which helps to ensure the purity of the compressed air and the normal operation of the equipment. The following is a detailed explanation of the water filtration of the air compressor: 1. the reason for the moisture generated in the air compressor. During the operation of the air compressor, due
Judging the gas demand of the equipment is a comprehensive consideration process involving many factors. The following are some key steps and considerations to help you accurately assess the gas needs of your equipment: Understand the type and working principle of the equipment: First, you need to clarify the equipment's
There is a reason for the failure of permanent magnet variable frequency air compressor. When the equipment fails, we must quickly find out the cause of the failure, restore the normal operation of the machine as soon as possible, and reduce the loss of the factory. Common Faults and Solutions of Permanent Magnet Variable Frequency Screw Air Compressor
The maintenance cycle of CNC machine tool air compressor depends on many factors, including equipment model, frequency of use, working environment, etc. Generally speaking, the maintenance of air compressor includes the replacement of oil filter, air filter, oil core and lubricating oil. The following are some specific maintenance
