Oil injection screw compressor exhaust oil requirement standard is an important technical index, it is directly related to the purity of compressed air and subsequent use effect. The following is a detailed analysis of the standard:
1. standard range
generally speaking, the standard value of the exhaust oil content of the oil-injected screw compressor has a certain range. Different sources give different numerical ranges, but it is generally believed that the exhaust oil content should be controlled at a low level. Specifically:
- standard value range it is pointed out that the oil content of compressed air in general oil injection screw air compressor is not more than 3ppm (I .e. not more than 3 mg/m & sup3;). However, there are also data mentioned that the standard value of the oil content of the oil injection screw machine is 10~30 mg/m & sup3;, depending on the equipment model, specifications and working conditions and other factors. It is important to note that these values may vary, as testing and evaluation methods may vary from source to source.
2. influencing factors
the discharge oil content of an oil-injected screw compressor is affected by many factors, including but not limited:
- equipment model and specification: Differences in the design and manufacture of fuel injection screw machines of different models and specifications may result in different exhaust oil content.
- Nozzle and Injection Quantity: The selection of nozzles and the control of fuel injection volume will directly affect the oil content of the gas production. Reasonable nozzle design and fuel injection quantity control help to reduce the exhaust gas content.
- Intake air temperature and pressure: The influence of intake temperature and pressure on the oil content of the oil injection screw machine is also significant. Under high temperature and high pressure conditions, the oil in compressed air may be more volatile and diffuse.
3. control measures
in order to control the oil content of the exhaust of the oil-injected screw compressor within the standard range, the following measures can be taken:
- selection of appropriate equipment: According to the actual needs of the appropriate selection of oil injection screw compressor model and specifications, to ensure that the exhaust oil content in line with the standard.
- Optimize nozzle and injection volume: Reduce the exhaust gas content by optimizing the nozzle design and controlling the fuel injection volume.
- Regular maintenance: Regularly maintain the oil-injected screw compressor, including cleaning the filter, replacing the lubricating oil, etc., to ensure its normal operation and reduce the exhaust oil content.
- monitoring and detection: Use professional monitoring and testing equipment to carry out real-time monitoring and regular testing of the exhaust oil content of the oil-injected screw compressor in order to find and solve problems in time.
4. Conclusion
to sum up, the oil content of the exhaust oil injection screw compressor is an important technical index, and its standard value range varies from different sources. In order to control the exhaust oil content within the standard range, it is necessary to select appropriate equipment, optimize the nozzle and fuel injection volume, regular maintenance, monitoring and testing measures. These measures will help to ensure the normal operation of the oil-injected screw compressor and meet the subsequent use requirements.
