Product Description

Introduction Of FBCD Coal Mine Extracted Explosion-Proof Counter-Rotating Fan

1. FBCD series mine explosion-proof extraction rotary axial flow local ventilator, should be used for underground large and small section roadway tunneling and extraction ventilation. The ventilator has the characteristics of reasonable structure, high efficiency and low noise.zmwm02
2, FBCD series mine explosion-proof extraction type of rotary axial flow local fan use environment gas temperature is -20 ° C ~ +40 ° C, relative humidity is not more than 95% (at 25 ° C), the altitude should not exceed 1000 m environment. The medium conveyed by the ventilator is allowed to contain methane and explosive gas, and the dust content of the passing gas shall not exceed 200 mg/m3. The ventilator is mainly used in coal mines with methane gas explosion hazard, installed in the return airway, and used in conjunction with the negative pressure air duct for pumping ventilation.
Second, the characteristics:
1. FBCD series mine explosion-proof extraction type rotary shaft flow local ventilator consists of two working hosts, and the two-stage impeller rotates in opposite directions. That is, the first-stage impeller rotates clockwise, the second-stage impeller rotates counterclockwise, and the number of the two-stage blades is prime. The air is extracted by the primary impeller and sent out after being pressurized by the secondary impeller. In addition to increasing the airflow energy, the second-stage impeller also has the function of the static guide vane in the common axial flow fan. It can smooth the airflow impact while increasing the airflow energy and reduce the wake vortex. , reducing noise.
2, FBCD series mine explosion-proof extraction type of rotary axial flow local fan blades, using domestic advanced ternary flow theory for aerodynamic performance design, using imitation aircraft airfoil circular plate twisted blade, high aerodynamic efficiency, high efficiency The area is wide and the energy saving effect is remarkable. Moreover, the airflow is smoothly and smoothly passed through the fan to ensure the safe operation of the fan.
3. FBCD series mine explosion-proof extraction type rotary axial flow local ventilator adopts outsourcing double muffler, which has ultra-low noise characteristics and has remarkable effect on changing the noise environment of the downhole restraint space.
4. FBCD series mine explosion-proof extraction type rotary shaft flow local fan supporting motor is YBF2 series mine explosion-proof three-phase asynchronous motor, voltage grade is 380/660V, 660/1140V. The ventilator is equipped with a non-stop oil-discharging device to ensure that the fan is injected and drained during operation, ensuring long-term reliable and safe operation of the motor in harsh environments.
