　　3、 Working principle of FBDNO5.6/2 * 11 explosion-proof type press in counter rotating axial flow local ventilation fan for mining

　　Composed of two sets of working motors, the two-stage impellers rotate relative to each other. The first stage impeller rotates clockwise, while the second stage impeller rotates counterclockwise. Air enters the first stage impeller through the collector to obtain energy and directly enters the second stage 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.

　　4FBDMining explosion-proof pressure type 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 ℃

　　Installation:

　　1. Due to slight vibration, the FBD fan can be placed directly on a level and flat ground

　　2. After installation, conduct a trial run inspection and start the first and second stage fans respectively to test the direction of rotation. When the wind direction is consistent with the direction indicated on the rotating sign, start the first stage for normal operation first, and then start the second stage for trial operation. Pay attention to whether there are any abnormal phenomena such as collision sound, current overload, or severe vibration. After the operation is good, it can be officially put into use.

　　After the fan has been tested and found to be in good condition without any abnormalities, it can be turned on and put into formal operation. During the start-up and operation of the fan, no one is allowed to stand at the diffuser outlet. If any of the following situations are found during the operation of the fan, it should be stopped urgently for inspection. The fan can only be used after the cause is identified and repaired.
