As a high-temperature environment, high-temperature fans are used for special fans. In addition to the high temperatures in the workplace, they also need their own materials to have strong high-temperature and high-pressure performance. The high-temperature fans can operate normally within a certain measurement range, including motor life and wind thermal expansion performance. And forced cooling performance. So why does the high temperature fan heat up?
The first is the high temperature life of the drive motor, which requires the drive motor windings to be insulated. The higher the insulation level, the higher the maximum winding temperature allowed, while supporting the need for high temperature motor oil. The rotor bearing needs to use more high temperature types. The main features are Large internal clearance, with special cage and dust cover. And the high-temperature manganese phosphate bearing is treated on the surface to prevent corrosion and improve operating performance.
Second, the forced cooling performance between the motor and the volute. Due to the high temperature environment, the fan generally circulates high temperature gas. When the high temperature and the drive motor shaft heat conduction, the forced cooling function of the motor part is cooled, and the temperature of the motor drive is normally used. Contribute to the life of the motor. The cooling fan installed synchronously with the motor shaft will be forced to run synchronously with the motor shaft in order to enhance the cooling function of the main shaft and achieve cooling purposes
Finally, it is the thermal expansion performance of fans and fan blades. Generally speaking, the higher the thermal conductivity, the stronger the heat, the higher the expansion coefficient, and the higher the temperature. Therefore, the best high-temperature fan material is stainless steel, followed by cold-rolled sheet. The last is aluminum, but considering the installation performance, cast aluminum fans are currently used to achieve high-temperature motor performance.
