How high is the high temperature fan?

　　The transmission modes of high temperature centrifugal fans currently include motor direct drive (A type), belt drive (C type) and coupling transmission (D type, F type). These three transmission modes have different advantages and disadvantages.
　　Type A means that the impeller of the centrifugal fan is installed on the shaft head of the motor. The fan size is small and cannot meet the requirements of large air volume or high pressure. The temperature of the medium should not be higher than 70°C. When the temperatThe centrifugal fan can withstand high temperature flue gas below 1000 degrees.
　　High temperature fan is a general term for a type of fan. It is suitable for conveying high temperature gas with slight corrosion, no spontaneous combustion, and working temperature below 1000 °C. The dust content of the medium should be less than 150mg/m3. environmental protection and other fields. According to the high temperature resistance level, it can be divided into four grades: first grade 80℃-300℃, second grade: 300℃-450℃, third grade: 450℃-600℃, fourth grade: 600℃-1000℃. When designing and selecting a high-temperature fan, the change of gas density under high-temperature gas, the dimensional expansion coefficient of each component of the fan, and the selection of high-temperature resistant materials should be fully considered. Different materials have different high temperature resistance and are classified as follows: FRP: ≤100℃, carbon steel (Q390, Q460, HG785): ≤500℃, stainless steel (304, 316L, 310S), duplex stainless steel 2205: ≤1000℃ . In addition to high temperature resistance, the corrosive gas of high temperature flue gas should also be considered, and high-quality materials that are resistant to high temperature and corrosion should be selected.
　　With the development and application of new technologies and the continuous progress of high temperature resistance technology, high temperature fans will be applied in more industries and fields in the future, and high temperature fans will also provide more complete solutions for more industries.ure is between 70-150°C, other measures need to be taken to cool down, otherwise the motor will be burned;
　　Type c means that the centrifugal fan and the motor are driven by belts and pulleys. This transmission method can withstand the medium temperature of 250 °C. The power of the motor should not be too large.
　　Type D means that the centrifugal fan and the motor are driven by a coupling, which can withstand the medium temperature of 250-500 °C and has the characteristics of high stability.
　　F type refers to 2 air intake boxes, bearing boxes are on both sides of the impeller, the fan runs stably and is easy to maintain. system;
　　The industries that high temperature fans have been applied to are: boilers, dust removal, desulfurization, denitrification, cement, metallurgy, power generation, gas and material transportation, smoke exhaust, etc. In addition to the difference in transmission mode, the material should also choose the appropriate high-quality plate according to the ambient temperature.
