Explosion-Proof Type of main shaft flow fan for coal mine

Date of issue:2022/12/2 16:23:29 Number of Views:

When the motor power of this series of fans is less than 200KW, it is equipped with the YBF series of explosion-proof type motor of the derivative series of YB series, and the voltage is 380V, 660V or 1140V. When the power is above 200KW, it can be equipped with YBF series of 6000V high voltage explosion-proof energy-saving type motor according to the needs of the mine. The motor is installed in an airtight cover in the main air duct. The airtight cover has a certain pressure resistance. It can isolate the motor from the gas containing in the fan flow passage, and also has a certain effect of heat dissipation. The airtight cover is equipped with two rows of streamlined air pipe, which are interlinked with the ground atmosphere through the main air duct, so that fresh air flows into the airtight cover, and at the same time, the air in the cover can maintain a positive pressure state during the operation of the fan. Due to the use of various technical measures in the design, the motor is always working under the condition that the gas concentration is less than 1%, which meets the safety and explosion-proof requirements.
