Stainless Steel Energy Saving Smelting Furnace Backward Boiler Fan
Introduction
It can work stably at a high medium temperature, and can output a large gas flow with low noise when the pressure requirement is met.The fan blade placement angle is optimized, more wear-resistant and longer service life.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.There are a variety of accessories to choose from.

FAQ
1. What parameters need to be provided when you design the industrial centrifugal fans?
Answers: Air flow, total pressure or static pressure, inlet temperature, local voltage and frequency, Altitude etc.
If there is flammable and explosive gas, or big dust loading in the medium, please also inform the designer.
2. How about your company’s pre-sales service and after-sales service?
Answers: Before our cooperation, we have the professional technical team to help you make the technical solution according to your working condition, to make sure the centrifugal fan efficiency operation.
