SWF series mixed flow fan has the same amount of wind machine number representing large xgf centrifugal fan exhaust fan, air pressure than the axial fan exhaust fan high htf, axially installation features: customers give low noise, low power consumption, efficient wide area easy to install, reliable operation highly valued than the centrifugal fan. SWF series mixed flow fan features a fan agency compact, easy to install, reliable operation: The axial flow fan than in the case of the same small amount of wind, air pressure, and can be directly connected to the duct, horizontal or vertical installation dtf smoke Fans, features easy operation; (2) low noise: The fan casing is specially designed to greatly reduce the outflow of noise. Under the unit amount of wind, air pressure unit working conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, get a higher fan pressure. In the mining industry, and senior civil ventilation system can replace the low-pressure centrifugal fan or replace the high-pressure axial fan silencer without requiring a lot of action. 3 Use a wide range: This series of products at single-speed and two-speed two models, according to different occasions, to change the mounting angle of the fan blades to change the number and speed to transform their requirements. SWF series mixed flow fans are widely used in industrial and mining ventilation, commercial high-rise buildings, hotels, restaurant, gymnasium, basement, garage, cold storage and other places, ideal for pressurized piping exhaust fan, use air supply and exhaust fan Common failure analysis of vibration, the causes are many, can be checked from the following aspects: transportation deformation due to the housing so that the impeller rotation grazing. At this will sound unusual and severe vibration, because the process of stroke and storage cabinet or impeller parts deformed. Fans foot bolts not tightened by the impeller compressive deformation, loose coupling, bearing damage the impeller balancing motor heat damage, it may be caused by one of the following reasons: motor bearing damage to the motor shaft and the fan-shaped tolerance wheel shell is not installed meet the technical requirements of the power supply voltage is too low exhaust fan fire, Rainbird environment (certified), Hulunbeier exhaust fan provided by Rainbird Wu County Environmental Engineering Limited.
