How to solve the problem of static electricity in the lubricating oil at the drive end of the AV100-6 Shaanxi Gas Turbine unit?
Thread Content
After the maintenance was completed on the axial flow compressors produced by SHANGU for the regeneration air compressors in PDH units, discharge was detected when measuring the voltage of the vibration probe at the drive end; it was determined that the lubricating oil contained static electricity by checking the oil pump in the start/stop oil station. I’m asking the experts here: has anyone encountered such a problem? How was it solved?
The problem of static electricity in lubricating oils is usually the result of a combination of factors such as the high insulation properties of the oil, fast oil flow rates, and environmental conditions. To address such problems, one can start from the following aspects: 1. **Improve the grounding system**: Ensure that the compressor and related piping systems are properly grounded. Poor grounding is a common cause of static electricity buildup. 2. **Use antistatic additives**: Adding antistatic agents to lubricating oil can reduce the insulation properties of the oil, thereby facilitating the release of static charges. 3. **Control oil flow velocity**: Excessively high oil flow velocities can increase the generation of static electricity; reducing the oil flow velocity appropriately may help to minimize static electricity formation. 4. **Inspect and maintain oil quality**: Ensure that the lubricating oil used meets the specifications set by the equipment manufacturer. Pollution of oils can also increase static electricity problems. 5. **Install static electricity elimination equipment**: Install specialized static eliminators or static grounding rods in the system to help dissipate static electricity. 6. **Regular inspection and maintenance**: Regularly check whether the equipment’s static protection system is functioning properly, including verifying that all grounding systems are in good condition. Solving static electricity problems requires taking into account the specific conditions of the equipment and the operating environment; multiple measures may need to be applied together to effectively address the issue. It is recommended to work with equipment manufacturers or professional experts in static electricity issues to ensure that the measures taken are both safe and effective. .
Check the equipment grounding and the insulation of the oil pump motor. Regarding the issues that occurred after the maintenance, please check whether there were any changes in the condition of the equipment before and after the maintenance
The issue of static electricity in the lubricating oil at the drive end of the AV100-6 Shaanxi Gas Turbine unit can be addressed from the following aspects: 1. Check the quality of the lubricating oil – Choose lubricating oil that meets relevant standards to prevent static electricity caused by inferior quality oil. Oil cleanliness: Regularly test the cleanliness of the lubricating oil to prevent static electricity caused by the accumulation of impurities. 2. Optimize the design of the lubrication system. Grounding measures: Ensure that the lubrication system is properly grounded to allow static electricity to be discharged promptly. Pipe material: Use pipe materials with good electrical conductivity to reduce the generation of static electricity. 3. Control the lubricating oil flow rate. Flow rate adjustment: Excessively high flow rates can generate static electricity; it is necessary to adjust it to a reasonable range according to the requirements of the equipment. 4. Regular maintenance and inspection: System inspection: Regularly check the lubrication system to ensure there are no leaks or damages. Static electricity detection: Regularly check the static electricity level and take measures promptly. 5. Use antistatic additives: Add antistatic agents to the lubricant to reduce static electricity buildup. 6. Environmental control: Humidity regulation: Maintain an appropriate environmental humidity to reduce the generation of static electricity. 7. Training and Operating Procedures: Operational training: Ensure that operators are familiar with the hazards of static electricity and the preventive measures. Standard operating procedures: Follow the operational guidelines strictly to avoid static electricity caused by improper handling. 8. Seek professional support: Technical support – if the issue is complex, it is recommended to contact SHANGU or the lubricant supplier for professional advice. Through these measures, the problem of static electricity in the lubricating oil at the drive end of the AV100-6 Shaanxi Blower unit can be effectively resolved, ensuring the normal operation of the equipment.
