The 9-08 series high pressure fan is generally used for forging furnace and high pressure forced ventilation, and can be widely used to transport materials, transport air and non-corrosive, non-self-igniting, non-viscous substances gas.
9-08 series centrifugal ventilation fan Structure
9-08 series centrifugal ventilation fan Application
Centrifugal fan is widely used in the cement industry, building materials industry, environmental protection industry, metallurgical industry, power industry projects such as large-scale dust collector, industrial boilers, ventilation systems, cooling.
9-08 series centrifugal ventilation fan Features
The fan can output higher gas pressure, and can provide more gas flow at the same time, low noise.
The fan blade placement angle is optimized, more wear-resistant and longer service life.
There are a variety of accessories to choose from.
The air damper can be used to flexibly adjust the pressure and flow of the fan during operation. It is also possible to select a variable frequency motor, with adjust the pressure and flow of the fan by changing the speed.
For the material of impeller and main shaft, we will choose high-strength carbon steel, low-alloy steel, high-temperature alloy steel, high temperature resistant high-strength alloy steel under different working conditions temperature and working speed, so that the impeller and main shaft still maintains a reliable strength at high temperature.
Fan systems with impeller diameters less than 1400 mm at normal temperature do not require additional bearing cooling devices, reducing users’ investment and maintenance.
The impeller is annealed to eliminate the internal stress generated during welding, ensuring that the impeller does not undergo creep and cracks.
The weld of the impeller and the main shaft are ultrasonic flaw detection to ensure that there are no welding defects and material defects to ensure strength.
The impeller is subjected to a high standard of dynamic balance correction to ensure stable operation of the fan.
