In order to ensure the normal use of centrifugal fans and prevent problems during use, lubricating oil is usually added to the equipment to help it operate more smoothly and function properly. However, when selecting lubricating oil, it is necessary to choose the one that is suitable for the equipment to better ensure high-speed operation of the machine. Therefore, the choice of lubricating oil is very important. So, how to choose it?

1. Centrifugal fans use continuous and forced smoothing, so lubricating oil with relatively low viscosity, good antioxidant stability, rust prevention, anti foaming, and good lubrication performance should be selected.

2. When selecting lubricating oil, it is necessary to follow the unevenness of the bearing's mission environment temperature to make its combination reasonable and reliable. If the ambient temperature is low, a lubricating oil with low viscosity and low pour point should be selected; When the ambient temperature is high, lubricating oil with high viscosity and flash point should be selected.

3. When selecting lubricating oil, all aspects should be considered, and the mission load refers to the static and dynamic loads directly borne by the bearing (or friction pair).

4. Under liquid lubrication conditions, the higher the viscosity of the lubricating oil, the greater its load-bearing capacity. When in a boundary slippery condition, viscosity has little effect on improving slippery transmission, and its oiliness and compressive performance cannot be lacking. At this time, a slippery oil with better compressive performance should be selected; For attack payloads, in places where it is often difficult to move or form an oil film, it is advisable to use grease or solid lubricants.

5. Corresponding lubricating oil with resistance to the centrifugal fan medium should also be selected, if there are special requirements for shortening the medium to the lubricating oil. In addition, when selecting oil, one should also refer to the lubricating oil recommended by the equipment manufacturer. It is necessary to consider the mission and environmental conditions of the equipment, and meet the needs of equipment operation; Secondly, it is necessary to increase the variety of lubricating oil products as much as possible to facilitate the management of lubricating oil products.
