　　2、 FBDNO5.0/2 * 7.5 mining ventilation fanUsage and characteristics: Mainly used in coal mines with methane gas and danger, for medium and long-distance ventilation in coal mining working faces. Ventilation fans have the characteristics of reasonable structure, high efficiency, obvious energy-saving effect, low noise, and selected air supply distance. It is a device for local ventilation in coal mines. To be used as a pressure type local ventilation fan in underground mines, suitable for local ventilation in mining faces and various chambers. At the same time, it is also applicable to local ventilation situations in other mines and various tunnel ventilation.

　　3、 FBDNO5.0/2 * 7.5 mining ventilation fanWorking conditions:

　　1. The ambient temperature is -20 to+35 ℃; The installation position elevation of the fan is -1000m to+1000m; The average monthly relative humidity is 90%; The conveying medium is air containing gases such as methane, with a dust content not exceeding 10mg/m3.

　　2. The working voltage is 380/660V. It can also provide working voltages of 220/380V, 660/1140V according to user requirements, and should not exceed ± 5% of the rated value. The power frequency is 50HZ.

　　3. The exhaust fan used underground should have a supply air volume greater than the working air volume of the fan.

　　The foundation for installing a pull-out ventilation fan should be firm and there should be no water around it. The height of the edge of the air inlet of the ventilation fan from the ground or top wall should not be less than 0.3m.

　　5. The equipped air duct should be able to withstand the pressure of a pull-out ventilation fan.

　　4、 FBDNO5.0/2 * 7.5 mining ventilation fanCharacteristics and working principle:

　　The local ventilation fan for mining, FBD series fan, consists of two sets of working motors, with two-stage impellers rotating relative to each other. The impeller rotates clockwise, while the secondary impeller rotates counterclockwise. Air enters the impeller through the collector to obtain energy and directly enters the secondary impeller. After being pressurized, it is sent out. The role of the secondary impeller is not only to increase the energy of the airflow, but also to have the function of static guide vanes in other types of axial flow ventilation. While obtaining the velocity component in the circumferential direction of the guide, it not only streamlines the energy of the airflow, but also reduces noise.

　　5、 FBDNO5.0/2 * 7.5 mining ventilation fanAdvantages and wiring methods:

　　FBDNO5.0/2 * 7.5 mining ventilation fan shells are equipped with wrapped noise eliminators to reduce the overall noise of the ventilation fan. The whole machine has a simple and compact structure, is sturdy and durable, safe to use, and easy to maintain. There are support legs and lifting holes on the fan for easy hanging or ground installation in the tunnel. The ventilation fan is driven directly by an electric motor, which has a more compact structure, is safe, convenient, and durable. The voltage level is (380/660) V or (660/1140) V. Users can choose the wiring method according to the power supply voltage requirements. The motor junction box has six wiring terminals and one grounding terminal. When the power supply is 380V. The body and structural components of this series of ventilation fans are welded with steel plates using the △ connection method; When the power supply voltage is 660V, use the Y connection method; When the fan leaves the factory, the electric motor is wired in Y direction. The base and main body of the motor are welded together, and the motor is directly cooled by the airflow conveyed by the impeller. The ventilation fan motor is a YBF2 series fan specific motor, with an explosion-proof form of mining explosion-proof type and an explosion-proof mark of "EXDI".
