Hazards of flaking anti-corrosion paint in carbon steel lubricating oil stations of centrifugal mixed refrigerant compressors and countermeasures

The peeling of anti-corrosion paint can cause the carbon steel components inside the lubricating oil station to rust, which in turn affects the purity and performance of the lubricating oil. If rust or paint fragments get mixed into the lubricating oil, they can cause wear or blockage of the moving parts such as bearings and gears inside the compressor, thereby affecting the proper operation and service life of the equipment. To prevent and address this issue, the following measures can be taken: 1. Regular inspections: Strengthen regular inspections and maintenance of the lubricant station to detect paint peeling and rust in a timely manner. 2. Cleaning and repair: Once paint peeling or rust is detected, it should be cleaned as soon as possible, and anti-corrosion paint should be reapplied if necessary to ensure the integrity of the protective layer. 3. Filtration system: Ensure that the lubricating oil station is equipped with an effective filtration system to remove solid particles resulting from paint shedding, preventing these particles from reaching the compressor. 4. Use high-quality paint: Choose high-quality anti-corrosion paint that is suitable for carbon steel and has good corrosion resistance, in order to extend the lifespan of the protective coating. 5. Employee training: Strengthen training for operation and maintenance personnel so that they understand the hazards of corrosion-resistant paint peeling off, as well as its prevention and treatment methods. Through the above measures, the impact of flaking anti-corrosion paint on lubricant performance and compressor operation can be effectively reduced, thereby improving the operational efficiency and safety of the equipment. .

The anti-corrosion layer consists of mechanical impurities that clog the filters and affect normal oil supply； 2. The broken paint particles form fine debris; if these escape the filter, they can damage friction surfaces such as bearing shells, thereby reducing their service life ； 3. When the anti-corrosion coating of the carbon steel oil tank fails, mechanical impurities will be present, which also have the same effects as the two points mentioned above.
