　　IIFBDNO5.6/2 * 11 mining counter rotating axial flow local ventilation fanform:

　　This series of fans consists of a collector fan, a secondary fan, an electric motor, and other parts. The body and structural components are welded from steel plates, and the electric motor is directly connected to the impeller for reliable transmission. The overall structure is simple, compact, sturdy, durable, safe to use, and convenient.

　　IIIFBDNO5.6/2 * 11 mining counter rotating axial flow local ventilation fanFunction and Characteristics:

　　FBDNO5.6/2 * 11 mining explosion-proof pressure type axial flow local ventilation fan is mainly used in places where gas, coal dust, and flammable gases are transported in mines and other industrial sectors. It can be used for mining excavation, well construction, local ventilation fan, and long-distance ventilation of tunnels in coal mines, metal mines, chemical mines, and other mines.

　　(1) This series of ventilation fans consists of collector fans, secondary fans, electric motors, etc. The body and structure are welded from steel plates, and the electric motor and impeller are directly connected for reliable transmission. The overall structure is simple and compact, sturdy and durable, and safe and convenient to use.

　　(2) The ventilation fan is driven by YBF2 series explosion-proof three-phase asynchronous motor or structurally integrated motor.

　　4FBDNO5.6/2 * 11 mining counter rotating axial flow local ventilation fanWorking Principle:

　　Composed of two sets of working motors, the two-stage impeller rotates clockwise relative to each other, while the two-stage impeller rotates counterclockwise. Air enters the impeller through the collector to obtain energy and directly enters the two-stage impeller, where it is pressurized and 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.

　　5FBDNO5.6/2 * 11 mining counter rotating axial flow local ventilation fanInstallation and precautions:

　　1. Check whether the cold insulation resistance of the motor stator winding meets the operating requirements

　　When the power is 380v/660v, the cold insulation of the motor must be greater than 0.38/0.66 megaohms before it can be used

　　2. Carefully inspect the supporting electrical equipment to ensure that the voltage is consistent, the capacity is sufficient, and all protections are in good condition

　　3. The electrical wiring should be firm and partially insulated. The motor and electrical components should be strictly protected from water damage, phase loss, and overload operation. When the motor is in rated working condition, the surface temperature of the casing should not exceed 150 ℃

　　VIFBDNO5.6/2 * 11 mining counter rotating axial flow local ventilation fanStructure, principle, and characteristics:

　　There are two impellers installed close to each other, driven by two explosion-proof motors to rotate in opposite directions. The airflow enters the first stage impeller along the axial direction from the collector end and is deflected into the second stage main engine. After being accelerated again by the second stage impeller, the airflow direction is reversed and discharged from the end along the axial direction.

　　7FBDNO5.6/2 * 11 mining counter rotating axial flow local ventilation fanEnvironmental conditions for use:

　　It can be placed flat on the bottom of the tunnel or hung on the tunnel wall for use.

　　When used on the base plate, the suction port (collector end) of the fan should not be immersed in water or cement.

　　The gas temperature in the usage environment should be -20 to 50 ℃, and the altitude should not exceed 1000m.

　　The rated frequency of the power supply used is 50Hz, and the rated voltage is either 380V/660V or 660V/1140V.
