FKD Series Mine-Use Pressed-Type Counterrotating Axial Flow Fans
The FKD series tunnel axial flow fans are primarily designed for applications in mining tunnels and similar environments.
Main Uses and Scope of Application
- The FKD series tunnel axial flow fans are primarily designed for applications in mining tunnels and similar environments.
Structure and Characteristics
(1) This series of fans consists of a collector, a Class I main unit, a Class II main unit, an electric motor, and a silencer. The casing and structure are fabricated by welding steel plates, while the impeller is pressed from manganese steel. The fan employs a direct-drive configuration between the electric motor and the impeller, ensuring reliable transmission. The overall design is simple, compact, robust, durable, safe to operate, and easy to maintain.
(2) The design and manufacturing employed various advanced techniques, including three-dimensional flow aerodynamics theory, anisotropic composite orthogonal blades, and wing profiles.
(3) It features a compact structure, low noise level, high efficiency, excellent aerodynamic performance, high air pressure, stable operation in working environments, and broad application scope. Designed and manufactured according to the ventilation requirements of varying tunnel excavation lengths and roadways, it is an ideal device for medium-distance local ventilation in mine tunneling operations.
(4) Equipped with an outsourced composite noise attenuation device, it exhibits ultra-low noise characteristics and delivers excellent sound reduction performance. The inlet and outlet silencers can be extended as required to further reduce noise levels.
(5) The tunnel axial flow fans produced by our company employ variable frequency control, allowing arbitrary adjustment of air volume to achieve energy-saving effects.
