In different high temperatures, the temperature of the high temperature axial flow fan is not very high. Compared with the centrifugal fan at thousands of degrees, its temperature can only be negligible, and the maximum temperature is only 200 degrees Celsius. However, compared with ordinary axial fans, this is a big improvement and can be applied in some special cases. For example, micro-fan boiler air supply, low-pressure high-temperature gas transmission.
Different structure, high temperature centrifugal fan is a kind of centrifugal fan. The motor is external, and there are various transmission methods, such as direct connection, V-belt transmission, coupling transmission, etc. It has a special water cooling device, while the high temperature axial flow fan is not complicated, it is only suitable for the direct connection of the motor or the belt drive, and there is no water cooling device. The explosion-proof high temperature axial flow fan is adopted to ensure safe use.
Different materials, high-temperature centrifugal fans are generally made of various heat-resistant alloy steels, stainless steel and a small amount of low-temperature manganese steel or carbon steel, while high-temperature axial fans are only made of carbon steel, and a small number of fans need anti-corrosion.
Different motors. Centrifugal fans are usually used in high-temperature energy-saving series of ordinary motors, explosion-proof motors, and the general protection level of explosion-proof requirements is IP54 and IP55; the power of multiple motors also includes several hundred kilowatts. The axial flow fan is a fan motor. When the axial flow temperature is particularly high, the protection level is IP65. It can work at high temperature at the same time, and there is water and oil. The role of the intermittent medium generated in the operation of the fan is steam or condensed water, which will not be affected and will not affect the life of the motor. Its motor power is small, generally 11 kilowatts or less
The maintenance workload is different. The high-temperature centrifugal fan should continuously supply cooling water, regularly check the wear of the impeller, and replace the lubricating oil and V-belt regularly. The maintenance workload is large, and the ordinary high temperature axial flow fan is maintenance-free.
