K Series Benefits:
1) The wing twist blade is used, which has high aerodynamic efficiency and remarkable energy-saving effect.
2) Diverse performance, complete specifications, and can be well matched with various resistance and air volume types of ventilation network, can maintain long-term efficient operation.
3) It is equipped with a steady flow ring device, the characteristic curve has no hump, no surge risk, and can operate safely and stable under any resistance state, and is suitable for multi-fan joint operation.
4) The motor and impeller directly connected structure, good overall stability, convenient installation, easy maintenance, low device resistance, higher efficiency than long shaft transmission and belt transmission, no transmission failure, no short shaft danger, mild foundation subsidence and slippage do not affect normal operation.
5) Compact structure, good moisture resistance. The main body of the fan is welded with steel plate and section steel, the blade is steel plate material, hollow, and the blade and the overall strength are high, which can effectively resist the underground blasting shock wave force, and can be installed on the surface or suitable for installation in the mine, especially suitable for the multi-stage station ventilation system of the fan station.
6) Can directly reverse the air supply, the reverse air rate is greater than 60%, there is no need to build the reverse air duct.
7) The blade installation is adjustable, and the fan mine can be adjusted at any time according to the change of mine production.
8) The amount of civil engineering is very low, which can save a lot of investment.
9) Low noise.
DK Series Benefits:
1) DK series mine ventilator consists of a collector, a primary fan, a secondary fan, a diffuser, a diffusion tower and other components.
2) The product is a pull-out anti-rotating axial flow fan, the blade is a warped wing type, the fan has low internal friction, low noise and high efficiency
3) The body is welded from steel and plate, compact structure, good reliability and easy installation.
4) The blade installation Angle is adjustable. When leaving the factory, the appropriate installation Angle can be selected according to the ventilation network parameters.
5) K series and DK series are equipped with spreader, more than 16 also need to be equipped with a diffusion tower, can part of the dynamic pressure into static pressure, reduce the export dynamic pressure loss, has achieved the purpose of energy saving.
6) According to the ventilation requirements, soft starting cabinet or frequency conversion cabinet can be used to perform soft starting or frequency conversion speed regulation of the fan, and remote automatic ventilation control can be achieved, which has significant energy-saving effect.
7) According to production needs, the cyclone can be run on a single machine.
8) When used in tunnels containing gas, it can be made into explosion-proof type.
9) We can make DK40, DK45, DK54, DK55, DK57, DK60 and other series according to the actual situation of the user's mine.
