General plant compressed air quality requirements

The oil output of the micro-oil air compressor is in the normal range of the exhaust oil content of about 1-5ppm, usually 3ppm as the common standard value. The following is a detailed explanation of this standard:

1. Definition of unit: ppm (parts per million concentration) indicates the mass proportion of oil in unit volume of compressed air, 1ppm means 1 mg of oil per cubic meter of air.

2. Industry specifications: According to the operating data of the air compressor, the exhaust oil content after oil and gas separation is usually controlled within the range of 1-5ppm. Among them, 3ppm is a typical value in most scenarios, reflecting the oil control level during normal operation of the equipment.

3. Standard basis: This value is directly related to the performance of the core components of the air compressor. For example, the oil filtration accuracy can reach 0.1 microns, and the new oil partial pressure difference is about 0.2bar. These design parameters jointly ensure that the exhaust oil content is at a low level.

4. Abnormal judgment: when the oil content exceeds 10ppm, it constitutes the phenomenon of "air compressor flying oil. At this time, it is necessary to check the key links such as the oil filling amount, the state of the oil return system and the separation efficiency of the oil barrel.
