Fan Classification And Performance Characteristics

- Jul 26, 2018 -

Fan classification:


There are three types of fans: A, axial flow roof fan: Model DWT-I, suitable for medium and low pressure, high flow applications. According to user needs, it can also be designed as two-way reversible air supply and exhaust, that is, a fan with equivalent characteristics of positive and negative working conditions, such as DWT-V type; B, centrifugal roof fan: model DWT-II type, DWT-III type Two types, suitable for occasions with small air volume and high pressure requirements; C. Motorless turbine exhaust fan: Model DWT-IV type, which is a kind of special arc type blade driven by the indoor and outdoor air pressure difference Thereby discharging the ideal energy-saving ventilation device for indoor air.


Fan performance characteristics:

It adopts advanced CAD software and is designed with multi-objective optimization. DWT-I series machine number 12#-24# A total of eight types of fan, using the method of changing the speed, angle and blade type, expanding the range of performance parameters to meet the needs of different working conditions, to achieve the fan and system area To achieve energy saving and noise reduction. The operation is stable, the service life is long, the moment of inertia is small, the dynamic stability is high, the operation is stable, and the requirements of the modern standards of various performance indicators are higher than the fan industry standard, ensuring that the wind turbine is in the leading position among the peers. The utility model has wide application range, and the fan can be made into an explosion-proof type according to the use requirements, and is suitable for forced exhausting in the occasions of flammable, explosive and corrosive gas; and has been tested by the provincial and municipal technical supervision bureaus for many times, and the user can use it with confidence.
