High-temperature fans are one of the more common types of fans. As the name suggests, we can understand their function. High-temperature fans can reach very high temperatures, which is their advantage. However, if we suddenly experience significant vibrations while using them, what could be the cause?
Their operating temperature ranges from 100℃ to 180℃, and they can also be used to transport non-corrosive, non-flammable, and non-viscous hot air, steam, and flue gas in various industries. Other similar performance options may also be selected, but the temperature of the transported medium must not exceed 180℃. The motor uses a special high-temperature motor, and the fluid part of the fan is made of heat-resistant materials, ensuring reliable cooling structure performance.
The causes of fan vibration mainly include the following aspects:
1. Misalignment of the coupling, meaning the center is not properly adjusted.
2. Severe damage to the bearings, causing vibrations.
3. Wear between the impeller and the casing.
4. Loose anchor bolts or poorly grouted and loose foundations.
5. High levels of dust during operation, which adheres to the blades.
6. Imbalance caused by wear on the impeller.
