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 to reduce their own duct resistance, improve ventilation efficiency; 2 × 18.5KW more fans to be mine Strong selection of Fenyang exhaust duct fan, 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, operation is flexible, with or without abnormal noise and so on. For high-power local fan, 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 to clean and improve the silencing effect. 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. Boiler Fan seek competitive Boiler Fan rely on the input of mechanical energy, improve gas pressure side to send gas machinery, it is a fluid driven machinery. Boiler Fan works with turbine compressor is basically the same, but due to the low gas flow rate, pressure changes little Linfen pipeline fan, generally do not need to consider changes in specific volume of gas that the gas as an incompressible fluid handling. Induced draft fan in the maintenance, after the pot open fan, felt seals found close to the front labyrinth seal installation Xinzhou negative fan, between the lack of oil guide ring, the outer felt pressed by the gland. Due to lack of oil guide ring, the result felt just stop living back to the oil port, resulting in poor oil return, it felt seals achieve its proper seal. Felt seal original installation location "newly remodeled spiral labyrinth seal or seals" position. Because no experience can learn a lesson before the induced draft fan turbine, power plants and design institute in program design and equipment selection process very carefully. On the one hand, Fan belong auxiliary boilers, flue gas system, there are many uncertainties in the operation. On the other hand, the selection results will be directly related to the bid price, the impact of competitive products. From inside the turbine efficiency, product cost, versatility future models, models of the manufacturing cycle minimum required careful consideration, Hangzhou Steam repeatedly discussed the results of the selection, seek the most competitive models.
