K45 mining withdrawable main fan

K45 mining extraction type main fan has diverse performance and complete specifications, which can be well matched with various types of ventilation networks with different resistance and air volume, and can maintain long-term efficient operation.Equipped with a stabilizing ring device, the characteristic curve has no hump. There is no risk of surge, it can operate safely and stably under any resistance state, and is suitable for multi fan joint operation.The structure adopts a direct connection between the motor and the impeller, with good overall stability, easy installation, easy maintenance, and low local resistance of the device. Higher transmission efficiency than belts and long shafts, no transmission faults, no risk of shaft breakage, mild foundation subsidence and slippage do not affect normal operation，Compact structure and good moisture resistance. The main body of the fan adopts a welded structure of steel plates and steel sections. The blades are made of steel plate material, hollow, and have high overall strength,Reversible reverse wind, with a reverse wind rate greater than60%No need to build a reverse air duct,The blade installation angle can be adjusted, and the fan operating conditions can be adjusted at any time according to the changes in mine production.
