coal mine Axial Flow Fan

The FBC (D) Z series coal mine surface explosion-proof extraction (reverse) Axial Flow Ventilation Fan can be used as a substitute product for large, medium, and small coal mines, as well as a product for new coal mines. The ventilation fan is equipped with non-stop air injection and oil discharge devices, which can add lubricating oil during operation. When the machine is shut down, the oil drain cover can be opened to drain the waste oil. The ventilation fan can transport underground air containing explosive gases of methane in the medium, and is generally designed for horizontal installation with a designed service life of no less than 20 years. The operating time before the first major overhaul shall not be less than 9000 hours.

The impeller of the ventilation fan is equipped with an H62 brass protective ring, which can be used in two processes: riveting and explosive welding. We have passed the friction spark safety test of the National Coal Mine Dust and Ventilation Fan Safety Quality Supervision and Inspection Center, and solved the fire or explosion hazards caused by blade collision during operation in dirty wind. The fan blades and the inside and outside of the casing have undergone multiple anti-corrosion and moisture-proof treatments, allowing the fan to operate for a long time in a humid environment, effectively solving the corrosion problem caused by other conditions on the fan.

The blades adopt internationally leading curved swept back combination 3D twisted orthogonal and aviation wing blade profiles, and the impeller is directly connected to the motor for transmission. Good aerodynamic performance, wide efficiency zone, high static pressure efficiency, and significant energy-saving effect. The ventilation fan blades adopt a steel hollow riveted structure and a high-strength cast (forged) aluminum structure, with adjustable installation angles. Users can adjust the air volume and pressure required for the front and rear stages; It can also be adjusted according to the frequency conversion control system to meet usage requirements and achieve energy-saving effects. At the same time, the unique blade structure design combined with a silencing device controls the noise during the operation of the ventilation fan within the range of national noise standards, reducing environmental pollution. The motor of the ventilation fan is placed in the flow channel and isolated from polluted air through a diversion chamber; When the ventilation fan is running, fresh air can be sent into the isolation room through the airflow duct to cool the motor, making the operation of the ventilation fan safer and more reliable.
