In the industrial field, high-pressure centrifugal fans, as an important mechanical equipment, have a complex structure consisting of an air inlet, air valve, impeller, motor, main shaft, bearing transmission, air outlet and other components. Correct selection of lubricating oil is crucial for the normal operation of high-pressure centrifugal fans.

High-pressure centrifugal fans usually require continuous lubrication. Therefore, when choosing lubricating oil, the following characteristics should be considered. First, low relative viscosity is the key. Lubricating oil with relatively low viscosity can effectively lubricate various components under high-speed rotation conditions to ensure the smooth operation of the fan. Second, good antioxidant stability is indispensable. This performance can extend the service life of the lubricating oil, reduce the frequency of replacement and lower maintenance costs. Third, rust prevention and anti-foaming properties are also extremely important. It can protect the equipment from corrosion and the influence of foam and prolong the service life of the equipment. Fourth, excellent lubricating performance is the basis. The selected lubricating oil should provide excellent lubricating effect between various components of the high-pressure centrifugal fan and reduce friction loss.

In addition, the working environment temperature has an important influence on the selection of lubricating oil. In a low-temperature environment, lubricating oil with low viscosity and low freezing point should be selected to ensure effective lubrication under cold conditions. In a high-temperature environment, lubricating oil with high viscosity and high flash point is more suitable. It can maintain the lubricating effect and avoid premature volatilization.

At the same time, the type of load borne, including static and dynamic loads, also needs to be considered. Under liquid lubrication conditions, the greater the viscosity of the lubricating oil, the greater its load-bearing capacity. However, when in boundary lubrication state, viscosity has little effect on improving lubrication. At this time, oiliness and extreme pressure resistance performance become crucial. Therefore, lubricating oil with good extreme pressure resistance performance should be selected. For places that bear impact loads or where it is difficult to form an oil film, grease or solid lubricant is a good choice. They can ensure that the equipment is properly lubricated and protected under the complex working conditions of high-pressure centrifugal fans.

In conclusion, the selection of lubricating oil for high-pressure centrifugal fans requires comprehensive consideration of various factors such as working environment, load type and equipment specifications. Only by correctly selecting lubricating oil can the smooth operation and long-term reliability of high-pressure centrifugal fans be ensured and provide strong support for the smooth progress of industrial production.
