High Air Flow Low Pressure Backward Industrial Boiler PA Centrifugal Fan
Introduction
1. 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.
2. 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.
3. Fan systems with impeller diameters less than 1400 mm at normal temperature do not require additional bearing cooling devices, reducing users’ investment and maintenance.
4. The impeller is annealed to eliminate the internal stress generated during welding, ensuring that the impeller does not undergo creep and cracks.
5. 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.
