Oil content standard for gas output of oil injection screw

Oil content of oil injected screw air compressor should be evaluated in combination with industry characteristics and process requirements

the oil-injected screw air compressor realizes cooling, sealing and lubricating functions by injecting lubricating oil, so a trace of oil will remain in the compressed air. The oil content level is affected by the equipment design, operating state and subsequent treatment measures, and the requirements for oil control are different in different application scenarios.

In the general industrial field (such as machining, pneumatic tool drive), the oil in the compressed air can be further reduced by the oil-water separator and filter device to meet the basic use requirements. However, for food packaging, pharmaceutical production, electronic components manufacturing and other industries that require high cleanliness, it is necessary to strictly control the oil content to avoid polluting the product or affecting the process accuracy. At this time, it is not appropriate to use oil-injected screw air compressor. The ideal equipment is to use Grencklin water-lubricated air compressor to provide medical grade oil-free gas.

During the operation of the equipment, the oil residue is closely related to the quality of the lubricating oil, the sealing performance of the compressor and the maintenance period. Regularly replace the lubricating oil, check the seal, clean the oil system, can effectively reduce the oil mixed. In addition, the use of precision filters or drying devices can further reduce the concentration of gas and oil to meet the needs of high cleanliness scenes.

In summary, the oil content of the oil injection screw air compressor should be adjusted according to the actual process requirements. Through equipment maintenance, oil management, and post-processing device configuration, operating costs and gas cleanliness can be balanced to meet the diverse needs of different industries for compressed air quality.
