PPM is the abbreviation of the English part per million, which means the number of parts per million or parts per million. It is usually used to express the content of trace substances in the mixture, with weight ratio (PPMw) and volume ratio (PPMv). In the field of air compressors, the reference to an oil content of 3PPM usually means a weight ratio, I .e. 3 parts by weight of oil per million parts of air. Specifically, if the weight of oil contained in 1kg of air is 3 mg, the oil content of the air compressor is 3PPM.
In addition, the oil content of the air compressor may also be affected by other factors, such as compression ratio, temperature, humidity, etc. Therefore, when selecting and using an air compressor, it is necessary to comprehensively consider the influence of these factors on the oil content, and select the appropriate air compressor model and configuration according to actual needs.
In addition, it should be noted that in practical applications, the lower the oil content of the air compressor, the better, because too high oil content will adversely affect the quality of the compressed air and the operational stability of the equipment. Therefore, some high-end air compressor products will adopt oil-free or low-oil design to meet the needs of occasions with high requirements for compressed air quality.
As a machine that provides air power, air compressors are widely used in many industries, so many industries can be used as air compressors. The following are some common industries that require air compressors: Manufacturing: Air compressors are mainly used in manufacturing
Compressed air is the basic power source of many industrial production lines, driving cylinders, controlling valves, driving spraying and packaging equipment, almost throughout the entire production process. The oil-free air compressor is used more in food, electronics, medicine and other scenes where the cleanliness of the gas source is required because the output gas does not contain oil. Whether the equipment can supply gas continuously and stably, the setting of maintenance cycle is a key issue.
A user who uses an air compressor, no matter how high-end the machine model he has used, will always have such a question: Is it better to have lubricating oil or oil in the compressor? Although only from the name, oil-free compressors and oil-free compressors have
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
If the air compressor does not drain water for a long time, it will increase the water content in the compressed air, affect the gas quality, and have an impact on the back-end gas equipment; the oil and gas separation effect becomes worse, and the pressure difference of the oil and gas separator becomes larger, which will also cause the parts to rust.
In the highly competitive air compressor market, how to choose an efficient, stable and environmentally friendly screw permanent magnet variable frequency screw air compressor has become the focus of many enterprises. Among the many brands, Shanghai Granklin Group, with its excellent technology and high-quality products, wins.
Whether food packaging factories can use micro-oil air compressors should be judged comprehensively according to specific scenarios and risk control measures. The core principle is "to avoid oil contamination of food". It can be used with caution on the premise of meeting cleaning requirements, but oil-free air compressors are more recommended. The following
Many different types of enterprises need to use air compressors. The following are some of the main application industries and types of enterprises: Manufacturing: Machinery manufacturing enterprises: used to drive tools, equipment and small machinery and equipment to improve production efficiency. Automobile Manufacturing
The core difference between oil-free compressed air and micro-oil compressed air lies in oil content, application scenario and technical characteristics. The following is a comparative analysis from four dimensions: 1. oil content and purification standard oil-free compressed air oil content: ≤ 0.01 mg/m3 (ISO compliance
Yes, oil-free air compressors usually do not require refueling. Oil-free air compressor, as the name suggests, is an air compressor that does not use oil in the compression process. Its core components, such as screws, are specially designed and manufactured to ensure that no lubrication is required during the compression process
