Selection of Lubricating Oil for Wear-Resistant High-Pressure Centrifugal Fans

Selection of Lubricating Oil for Wear-Resistant High-Pressure Centrifugal Fans

Wear-resistant high-pressure centrifugal fans operate smoothly under normal conditions without issues. Adding lubricating oil ensures smoother operation and maintains proper functionality. However, when selecting lubricating oil, it is crucial to choose an appropriate type to support high-speed machine operation. The method of lubricant selection is highly important—how should one make the best choice? 1. Wear-resistant high-pressure centrifugal fans operate continuously under forced stability conditions. Therefore, lubricants with relatively low viscosity and high oxidation stability must be used. Greases possessing rust prevention, anti-foaming, and anti-wear properties are essential. 2. When selecting grease, match it reasonably based on the unevenness of the bearing's operating environment temperature to ensure reliable operation. For low ambient temperatures, choose grease with low viscosity and low freezing point. For high ambient temperatures, select grease with high viscosity and high flash point. 3. When choosing lubricants, consider all aspects. The working load refers to the static and dynamic loads directly borne by the bearing (or friction pair). 4. For liquid lubrication, higher viscosity grease provides greater load-carrying capacity. Under boundary lubrication conditions, viscosity-induced lubrication effectiveness is minimal; instead, anti-wear and extreme-pressure properties become essential. In such cases, select grease with superior extreme-pressure performance. For impact loads where movement and oil film formation are difficult, grease or solid lubricants are recommended. 5. Wear-resistant high-pressure centrifugal fans also require corresponding lubricating oils. Some media impose specific requirements on lubricants. Additionally, manufacturer-recommended lubricants should be consulted during selection. First, align with operational demands by considering task requirements and environmental conditions. Second, diversify lubricant types to facilitate management. The above outlines lubricant selection for wear-resistant high-pressure centrifugal fans. Choosing the appropriate lubricant is crucial as it directly impacts equipment performance and operational efficiency. To ensure reliable machine operation and extend service life, always select the correct brand of lubricant during purchase. This guarantees worry-free usage and prevents operational issues.
