What are the causes of wear and tear in high-temperature-resistant boiler centrifugal fans?

What are the reasons for wear and tear in high-temperature-resistant boiler centrifugal fans? This is a question relating to the operation of these fans. What is the answer to this question? Please see the detailed explanation below. 1. Dust-induced wear in high-temperature-resistant boiler centrifugal fans If a large amount of fine dust adheres to a high-temperature boiler centrifugal fan, the bearings, blades and motor will suffer long-term cumulative damage. Due to the small particle size and wide variety of dust types, it is difficult to remove much of the dust effectively, making it easy to damage the fan’s vulnerable parts. At the same time, in order to reduce costs and improve the ventilation efficiency of high-temperature boiler centrifugal fans, some fan application units have reduced the use of dust collectors. This causes significant damage to the high-temperature boiler centrifugal fan, thereby increasing the risk of fan failure. 2. Unreasonable operating conditions for high-temperature boiler centrifugal fans Different locations and functional requirements necessitate different operational adjustments for high-temperature boiler centrifugal fans. However, due to differences in design and practice, as well as varying functional requirements, issues arise with fan selection; fans are prone to overloading, and the problem of wear and tear on high-temperature boiler centrifugal fans is exacerbated. 3. Excessive rotational speed of high-temperature boiler centrifugal fans Excessive operating speed is another major cause of wear in high-temperature boiler centrifugal fans. Analysis of wear data from wind turbines indicates that the extent of wear is directly related to the operating speed of the fan. Under high-temperature conditions, if the operating speed of a high-temperature boiler centrifugal fan is doubled, the rate of wear increases threefold.
