The main application of SDF counter-rotating axial flow jet fan
SDF counter-rotating axial flow jet fan
SDF-II (two-speed) counter-spinning counter-rotating axial flow tunnel fan is mainly used in high-speed rail, highway, railway, diversion tunnel metal mine tunnel and other fields. The temperature of the conveying medium does not exceed 60 ° C, the temperature is not greater than 95 ± 3% (25 ° C) and non-corrosive.
2. Structure and characteristics:
(1) This series of fans are composed of current collectors, primary fans, secondary fans, motors, and mufflers. The body and structure are welded by steel plates. The impeller is die-cast from aluminum alloy. The fan adopts a direct connection between the motor and the impeller. The transmission is reliable. The overall structure is simple and compact, rugged, safe to use and easy to maintain.
(2) It adopts international advanced ternary flow aerodynamic theory, equal-swept combination orthogonal blades and airfoils, and many other high-tech designs and manufactures, which have advanced levels at home and abroad.
(3) It has the characteristics of compact structure, low noise, high efficiency, good wind dynamic performance, high wind pressure, stable operation in the work area, and a wide range of efficient applications. Depending on the length of the tunnel face and different ventilation requirements of the roadway, it can be used as a whole or in stages, thereby reducing energy consumption. Energy saving, it is the ideal equipment for local ventilation in the middle of the tunnel.
(4) Adopting outsourced double-type muffler, with ultra-low noise and other characteristics, the muffler effect is good.
