Shanxi nagorye blower fan must have safety devices installed to prevent accidents by professionals familiar with installing and wiring the relevant safety requirements. After the fan installation, by hand or lever toggle wheel, check if there are too tight or collision, the availability interfere with the rotation of the article, no abnormal phenomenon tunnel fan type, the exposed part of the commissioning can be carried out, the fan drive device should guard (user) as the fan inlet pipe is not connected, but also need to purchase fencing or other mounting device (user-supplied). Shanxi fan future development will further improve aerodynamic efficiency, device efficiency and the utilization efficiency of the fan to reduce power consumption; with variable pitch axial fans instead of large centrifugal fan; reduce fan noise; improve the smoke, dust exhaust fan impeller and casing wear; to achieve variable speed adjustment and automatic adjustment. With the continuous development of science and technology, people used to the requirements of the fan is getting high, on wind turbine technology in terms of the current development trend of foreign large tunnel fans, we will continue to increase towards the fan capacity, high efficiency, small size and low speed noise direction. Fan noise is one of the main sources of noise pollution in industrial production. Shanxi large-scale and high-speed fans make noise more prominent. Low-frequency noise, Shanxi fan mainly through improved fan design, reduce body noise tunnel turbine prices, if below standard, can be taken to install mufflers and other measures. With the continuous development of science and technology, asking people to use the suction fan is also getting higher and higher, it is the development of wind turbine technology in terms of current trends abroad, will continue to increase along the fan capacity, high efficiency, high speed and low noise miniaturization direction.
