Screw compressor discharge oil content ppm unit

The discharge oil content of screw compressors is usually expressed in ppm(parts per million, parts per million). This is a concentration unit used to describe the proportion of oil in the gas discharged from the compressor. The smaller the ppm value, the lower the oil content in the gas.

In the screw compressor, due to the working principle of the compressor and the use of lubricating oil, the discharged gas may contain a certain amount of oil. These oils may have an impact on subsequent equipment or processes, especially in applications where high purity gas is required.

In order to reduce the oil content in the exhaust gas, some measures can be taken, such as the use of efficient oil and gas separators, regular replacement of lubricating oil and filter elements, and adjustment of compressor operating parameters.

It should be noted that the ppm value is only a relatively fixed standard, and the actual oil content may vary due to factors such as the compressor model, working conditions, and use time. Therefore, when using screw compressors, it is recommended to regularly check the oil content in the exhaust gas to ensure that it meets relevant standards or process requirements.

In addition, different industries and applications may have different requirements for exhaust gas oil content. Lower ppm values may be required in certain situations where gas purity is required, such as food processing and medical industries. Therefore, when choosing a screw compressor, the appropriate model and configuration should be selected according to the specific application requirements and standards.
