Analysis of the meaning of oil content 3ppm
"Oil content 3ppm" is an index to measure the oil residue in compressed air, and its specific significance should be understood in combination with scientific definition and industry application scenarios:
definition of 1. ppm
- ppm(parts per million) is the concentration in parts per million, or "parts per million".
- Oil content 3ppm: Refers to the residual amount of oil in compressed air is 3 mg/m3 (mg/m & sup3;), which is equivalent to 3 mg of lubricating oil or other oily substances per cubic meter of air.
The practical significance of 2. 3ppm in the industry
- entry threshold for high purity scenarios
- the food, medicine, electronics manufacturing and other industries have extremely high requirements for the purity of compressed air, usually requiring oil content ≤ 0.01 mg/m & sup3;(close to the oil-free standard).
- 3ppm(0.003 mg/m & sup3;) Although lower than the limit requirements of some industries, it still needs to be further purified by subsequent filtration equipment (such as precision filters and activated carbon adsorption) to meet the needs of direct contact with food or electronic components.
- Correlation between equipment maintenance and life
- oil residues in compressed air may adhere to the surface of pipes, valves or pneumatic components, and long-term accumulation will lead to a decrease in equipment efficiency, aging of seals or an increase in failure rate.
- Although the oil content of 3ppm is low, it still needs to be monitored regularly to avoid the stability of the production line due to the accumulation of oil.
- Environmental and Compliance Requirements
- some industries (such as medicine and food) need to be certified by international standards such as ISO 8573-1, among which the classification requirements for the oil content of compressed air are strict (such as Class 0 corresponding to no oil, Class 1 corresponding to ≤ 0.01 mg/m & sup3;).
- The oil content of 3ppm should be comprehensively evaluated in combination with other indicators (such as particulate matter and moisture) to determine whether it meets the specific industry specifications.
Technical Advantages of 3. Granklin Air Compressor
granklin water lubricated single screw air compressor through innovative design, from the source to reduce the risk of oil content:
- oil-free lubrication technology
- using water instead of traditional lubricating oil, no oil is mixed in the compression process, and the oil content can theoretically approach zero, far below the 3ppm standard.
- Precision filtration system integration
- it can be matched with a high-efficiency filter (such as a precision filter element of 0.01μm grade) to further intercept possible trace oil and ensure that the purity of the output air meets the highest industry requirements.
- Eco-friendly and simplified maintenance
- there is no need to dispose of waste oil, reducing environmental compliance costs; maintenance only needs to pay attention to filter replacement and water quality monitoring, reducing equipment loss due to oil pollution.
4. practical application recommendations
- scene adaptation: If the oil content of the production line is ≤ 3ppm, it is necessary to combine the oil-free technical advantages of Granklin air compressor and configure precision filtration equipment to ensure that the final output air purity meets the standard.
- Monitoring and verification: Regularly monitor the oil content of compressed air through an oil detector (such as infrared spectroscopy) to ensure long-term stability below 3ppm.
Conclusion
"Oil content 3ppm" is a key indicator to measure the residual oil in compressed air, reflecting the level of air purity. Granklin water lubricated single screw air compressor through oil-free technology design and precision filtration system integration, can easily meet or exceed this standard, for food, medicine and other high purity demand industry to provide reliable protection.
