The role of the induced draft fan induced draft fan as an important mechanical ventilation, environmental protection in multiple industries, metallurgy, boilers, etc. play a huge role, as you explain in detail the following: 1, boiler flue gas extraction fan, either power plant boiler, or a variety of industrial boilers, coal-fired, oil-fired boiler, the flue gas is required for the induced draft fan leads. 2, furnace flue gas heat recovery and lead to three, the wind dust 4, 5 workshops exhaust emissions, chemical gas transportation use mine when fans should pay attention to what matters mine Boiler Fan equipped with a hairdryer to be larger than the diameter of the fan impeller diameter, in order to reduce their resistance Xinzhou suction duct fan, improve ventilation efficiency; 2 × 18.5KW than mine must choose a strong fan duct to prevent excessive pressure, blowing crack hairdryer. Periodically clear the muffler shell. Former domestic coal mining companies often fan adjustment method many forms. So when you use mine fan should pay attention to what matters it? Mine fans should be checked before each fastener is complete, the connection is solid and reliable, whether to run flexible Yuncheng hearth fan, with or without abnormal noise and so on. For local fan ducted fan power of Linfen, regularly to the front and rear of the motor lubricating bearings and prolong life; dust and debris on the plate, explosion-proof axial fans; paute anechoic material clean, improve consumer sound effects. Mine fan when not in use, should be placed in the air circulation in the square to prevent moisture, corrosion. Mine maintenance using adjustable pipe network resistance method, adjust the speed law, regulating gas inlet guide vane method, when adjusting the impeller blades and other forms of law with a fan debugging. According to the fan shaft power characteristic curve is displayed. Fan speed changes. Proportional to the cube of shaft power and speed changes; visible. Adjustable speed low-noise axial fan is mine fan energy-saving effect is most obvious technical way. Luliang proof fan, fan, fan nagorye provided by the Shanxi nagorye blower limited liability company. Shanxi nagorye Blower Co., Ltd. (www.sxgfj.cn) strong, credible, Shanxi Xinzhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
