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 moisture content in the air is not a fixed value, but is affected by many factors, including temperature, humidity, geographical location and climatic conditions. In the air at normal temperature and pressure, the moisture content may be in the range of hundreds to thousands of ppm(parts per million
In the air compressor market, there is a certain price difference between frequency conversion air compressor and power frequency air compressor because of their different working principles and performance characteristics. The water-lubricated air compressor produced by Shanghai Granklin Group has a layout in both types of products, which is for us to explore.
Q: Oil-free air compressor need maintenance? A: Oil-free air compressor needs maintenance. Although the oil-free air compressor does not need to add lubricating oil, like other equipment, it also needs regular maintenance, which is necessary to ensure the long-term stable operation of the equipment.
In semiconductor manufacturing, compressed air as a key power source and process medium, through the wafer preparation, precision cleaning, lithography, etching, film deposition, ion implantation, packaging testing and other core links, its role can be summarized as follows: 1. environmental control and engineering
The laboratory air compressor is mainly used to provide high-quality compressed air for the experiment to meet the demand for air source during the experiment. Specifically, laboratory air compressors play an important role in many aspects: Provide fresh air: In biological experiments, air compressors
During the start-up of the air compression system, it is recommended to operate in the following order: Start the air compressor first First, start the air compressor to enter the normal operation state. At this time, compressed air begins to generate and is initially cooled by the after-cooler, but the air still contains
The air compressor room system of the power plant is the aerodynamic center of the entire power plant. From instrument control to ash transportation, cooling, maintenance, and safety, it is inseparable from it everywhere. However, the water lubricated oil-free screw air compressor has become the mainstream choice of many power plants in the instrument gas and key control links with high air quality requirements because the air is clean and oil-free and maintenance is worry-free.
The question of whether an air compressor requires a separate equipment room involves a number of considerations. The following is a detailed analysis based on relevant standards and industry practices: 1. safety factors Air compressor is a dangerous equipment involving high-pressure gas.
Confirm whether it is an oil-free air compressor can be judged by the following aspects: Check the oil tank 1. to the appearance characteristics: the machine shell of the oil-free air compressor usually does not have an oil tank, the appearance of the whole machine is relatively simple, and the number of oil pipes is limited. If the air compressor appearance
Hospital air compressor room is an important part of hospital facilities, mainly for the hospital to provide a variety of medical equipment required by the compressed air. This compressed air is widely used in all aspects of medical diagnosis, treatment, surgery and daily operation. Specific
