Gear oils with grades 220-320 are high-viscosity, heavy-duty industrial gear oils commonly used to lubricate gear assemblies in various industries such as metallurgy, coal mining, cement production, and chemical processing. During application, multiple issues may arise that directly impact equipment operational efficiency, service life, and safety. Below are common problems, their causes, and corresponding improvement measures.

1. Common problems, causes and improvement measures of gear oil
| Fault | Cause | Solution |
Oil Oxidation and Degradation (Darkening, Increased Viscosity, Acidic Formation) | 1. High-temperature load operation 2. Air intrusion 3. Metal catalysis 4. Moisture contamination | 1. Choose high-quality, antioxidant oil. 2. Control oil temperature and avoid prolonged high-temperature operation. 3. Prevent contaminants. 4. Perform regular oil analysis. |
| Gear Surface Wear and Pitting | 1. Insufficient lubrication 2. Insufficient oil film strength 3. Particulate contamination | 1. Select an oil with appropriate viscosity and extreme pressure rating. 2. Ensure oil cleanliness. 3. Check the oil level regularly to ensure adequate lubrication. |
| Oil Foaming and Cavitation | 1. Oil quality issues 2. Air intrusion 3. Contamination by other oils | 1. Select high-quality oil. 2. Optimize oil return system design. 3. Avoid contamination from different oil brands. |
| Sludge and Varnish Deposition | 1. Oil oxidation 2. Tiny wear particles 3. Mixing different oil | 1. Use high-performance oil 2. Enhance filtration 3. Keep the oil clean and dry |
| Water Contamination | 1. Cooler leak 2. In a humid environment | 1. Choose an oil with good water separation and rust prevention properties. 2. Use a high-efficiency respirator to reduce moisture inhalation 3. Filter and dispose of the oil promptly |
| Oil Leaks | 1. Damaged seal 2. Incompatible oil and seal 3. Improper viscosity selection 4. Equipment hardware failure | 1. Ensure oil seal compatibility. 3. The breather to keep it unobstructed. |

2. The Importance of Gear oil Filtration Process
During the use of industrial gear oil, tooth wear, oil oxidation, and degradation are often caused by mechanical impurities, particulate matter in the oil, or foreign contaminants. Therefore, during refueling or filtration, it is necessary to filter and purify the gear oil to reduce the amount of particulate matter and reduce the wear, abrasion, and pitting that can occur on the gears.
Chongqing Kaiqian's TY-R series vacuum oil filter can dehydrate, degas, and remove impurities from gear oils with a grade of 68 to 220. For gear oils with a grade of 320 or higher, a high-flow filter should be selected for satisfactory results. For more questions about gear oil filtration, contact us for the best solution.
