The oil content of the exhaust gas of the micro-oil screw machine usually contains 30 to 40 mg of oil per cubic meter of compressed air, equivalent to 30ppm to 40ppm however, the actual value may vary depending on the equipment model, brand, operating conditions, etc. The following is a specific analysis:
theoretical value under 1. standard conditions
- nominal oil content: Under standard working conditions, the exhaust oil content of the micro-oil screw machine usually does not exceed 5ppm (one part per million), which is the basic requirement of the industry for the micro-oil screw machine.
- Actual oil content range however, in practical applications, due to factors such as working conditions and maintenance, the exhaust oil content of the micro-oil screw machine usually contains 30 to 40 mg of oil per cubic meter of compressed air, which is equivalent to 30ppm to 40ppm.
2. Factors Affecting Exhaust Oil Content
- performance of oil separation core: If the oil separation core is damaged or blocked, the oil and gas separation effect will fail, causing a large amount of cooling oil to be discharged with the gas.
- Working condition of return line: The oil return pipeline is blocked, broken or incorrectly installed, which will cause the oil to fail to return smoothly, and then be carried into the system pipeline by compressed air.
- Control of system pressure: Too low system pressure control will cause the centrifugal force in the separator to be less than the centrifugal force required by the work, making the oil and gas separation incomplete.
- The amount of cooling oil added in the compressor: Too much cooling oil is added, which exceeds the range of the compressor, which will cause the oil content in the exhaust gas to be too high.
- Operating temperature and operating environment of air compressor: The higher the temperature of use and operation, the oil content may also increase.
3. Measures to Control the Oil Content of Exhaust Gas
- regularly check and maintain the oil separation core and oil return line to ensure that it is in good working condition.
- Reasonable control system pressure to avoid the adverse effects of too low or too high pressure on oil and gas separation.
- In strict accordance with the requirements of the compressor to add the right amount of cooling oil, To avoid too much or too little oil on the exhaust oil content.
- Use of high quality lube oil and air filters, To reduce oil consumption and the entry of impurities.
