The eccentric bearing corrosion is caused by a variety of internal and external factors, summed up: 1, the metal surface finish (poor oxygen concentration cell corrosion). 2, the metal material itself, the chemical composition and structure. 3, the solution component in contact with the metal surface and the pH value; 4, the ambient temperature and humidity. 5, the contact with the metal surface relative to a variety of environmental media. 6, the addition of sweat also lead bearing corrosion reasons, the pH value of 5 to 6. Therefore, in order to prevent corrosion caused by hand sweat, installation and production personnel should wear gloves, it should not touch the imported bearings.
Oiled to prevent eccentric bearing rust
Immersion method: some small imported bearings soaked in anti-rust oil, the oil film thickness can be achieved through the control of anti-rust oil temperature or viscosity.
2, brushing method: Brush attention evenly coated in imported bearing surface, not produce accumulation and pay attention to the coated to prevent leakage.
3, the spray method: some large rust-proof material is not suitable for immersion method oiled, generally about 0.7Mpa pressure filter compressed air spray in the air cleaner place. Spray application of solvent-diluted anti-rust oil or a thin layer of anti-rust oil. This method must be used to improve fire safety and labor protection measures.
Eccentric bearing surface rust pretreatment method:
1, surface cleaning: cleaning must be combined with the nature of the imported bearing surface and the prevailing conditions.
2, the surface is dry cleaning available filters clean dry compressed air. Or using a drier and dried to a temperature of 120 to 170 ° C in the last wipe dry with clean gauze.
