Causes of axial fan wear

The wear and tear of the axial flow fan will cause the fan to vibrate, shorten the life of the fan, and cause the fan to fail to work normally in severe cases. In particular, the blades of wind turbines are the most worn out, which not only destroys the flow characteristics in the wind turbine, but also easily causes major accidents such as blade breakage and speeding. Therefore, it is very necessary to understand the reasons for the wear of the axial flow fan, and then take the corresponding anti-wear measures. Today, the editor collected some reasons for the wear of axial fans on the Internet, and shared with you
The basic causes of common axial fan wear are as follows:
1. Wear of dust on the fan
A large amount of microscopic dust during fan operation will cause damage to fan bearings, blades, and motors due to long-term accumulation. Due to the small particle size and many types of dust, a lot of dust cannot be effectively removed, and it is easy to cause damage to the vulnerable parts of the fan. . At the same time, in order to control costs and improve the ventilation effect of fans, some fan application units have reduced the application of fan dust collectors, which will cause strong damage to the fans by dust and increase the risk of fan wear and failure.
2. The operating conditions of the fan are unreasonable
Different positions and different function settings require different fans and different state adjustments to adapt. The gap between the design and the actual, the difference in functions and needs forms the problem of fan selection, which is very easy to cause fan overload work and increased fan wear. problem.
3. The fan runs too fast
Excessive running speed is another important cause of fan wear. According to the data analysis of fan wear, the degree of wear is related to the running speed of the fan. Under high temperature conditions, the running speed of the fan is doubled, and the wear of the fan is increased by 3 times.
