The oil content standard of screw air compressor is usually stipulated by relevant international, national or industry standards. Generally speaking, for the oil injection screw air compressor, the oil content of the compressed air is not more than 3ppm (that is, the oil content per cubic meter of compressed air is not more than 3 mg) is in line with the standard. However, there are also more stringent standards, such as according to the "Air Compressor Pollutant Emission Standard" (GB/T 3785-2006), the oil content in the air discharge of the screw air compressor should not exceed 5mg/m3.
In addition, if it is an oil-free screw air compressor, its compressed air oil content standards are more stringent. According to the ISO 8573-1 industry standard, the oil content of the compressed air of the oil-free air compressor must be less than 0.01 mg/m & sup3;, in order to reach the CLASS 0 level, is recognized as oil-free compressed air.
Please note that different screw air compressors may need to meet different oil content standards, so the specific standards should be determined according to the equipment model and application scenario. When using the screw air compressor, the oil-water separator, filter element and other components should be checked and replaced regularly to ensure the quality of compressed air and the normal operation of the equipment.
Air compressors, namely air compressors, belong to the category of general machinery and equipment. It is a kind of equipment used for compressed air, which is widely used in various industrial and commercial fields. According to different compression principles and structural characteristics, air compressors can be divided into many types, such as piston air
In the pharmaceutical production process, compressed air is widely used in many key links because of its clean, dry, stable and precise control characteristics. Its main functions include the following aspects: 1. Power drive and equipment operation Pneumatic tools and equipment: compressed air is pneumatic
Q: How to solve the problem of too serious moisture in the air compressor? A: It is normal to use more moisture in the air compressor. As the name implies, the air compressor heads are all lubricated with water, and the compressed gas must contain water vapor.
The air compressors commonly used in the factory mainly have the following types: Piston air compressor: simple structure, relatively cheap price, large pressure area, suitable for a variety of environments. But as an earlier type of air compressor, its speed compared to the new generation of air
The problem of oil content at the outlet of natural gas reciprocating compressor mainly depends on many factors, including but not limited to the working state of the compressor, sealing performance, use and management of lubricating oil, and gas treatment process. If the sealing performance of the compressor is not
Whether the product equipment is good or not is never blown out by itself. Each user has his own consideration in terms of cost performance. Domestic air compressor need to purchase oil-free air compressor, you can contact us "Shanghai granklin group". Professional production & ldquo
The rice processing line has extremely strict requirements on the oil content of the air, which usually needs to be controlled below 0.01 mg/m & sup3 to meet the food-grade cleanliness standards.
When discussing the air supply pressure of the air compressor, we need to pay attention to its normal fluctuation range to ensure the stable operation of the equipment and the smooth progress of production. The normal fluctuation range of air supply pressure of air compressor is an important technical parameter, which is affected by many factors, including air
The permanent magnet synchronous variable frequency air compressor has excellent performance and efficiency, and has many significant advantages, so it can be considered a good choice. The following is a detailed summary of its advantages: high efficiency and energy saving: permanent magnet synchronous motor has high efficiency characteristics, making permanent magnet
The presence or absence of oil in an air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Oil containing machines generally have a higher oil content, while oil-free machines have an oil content of 0.01ppm. Therefore, this oil content is used to distinguish between oil containing and oil-free air compressors Choosing the appropriate air compressor based on the demand for gas sources in different industries can save operational costs for enterprises
