K40 Mine Axial Flow Fan – Mine Ventilator – Application
The K40 mine axial flow fan and mine ventilator are specifically designed to meet the ventilation needs of various non-mine industries such as metallurgy, mining, gold, chemical, building materials, and nuclear industries. It can be used as the main fan or auxiliary fan. It can be installed on the surface or underground and is suitable for multi-fan combined operation. It is an ideal station fan in multi-fan series multi-stage station ventilation systems. It is also applicable for ventilation and air exchange in large workshops, tunnels, and civil defense projects.
K40 Mine Axial Flow Fan Mine Ventilation Fan Features
(1) It adopts twisted airfoil blades, which have high aerodynamic efficiency and remarkable energy-saving effect.
(2) It has diverse performance and complete specifications, and can be well matched with various types of ventilation networks with different resistance and air volume. It can maintain long-term efficient operation.
(3) It is equipped with a constant flow ring device, and the characteristic curve has no hump. There is no surge risk. It can operate safely and stably under any resistance condition and is suitable for multi-fan combined operation.
(4) It adopts a structure of direct connection between the motor and the impeller. The overall stability is good, installation is convenient, maintenance is easy, and the local resistance is low. It has higher efficiency than belt and long shaft transmission, has no transmission faults, no dangerous shaft breakage, and slight foundation subsidence and slippage do not affect normal operation.
(5) The structure is compact and has good moisture-proof performance. The main body of the fan is made of steel plate and type steel welding structure, the blades are made of steel material, hollow, the strength of the blades and the overall structure is high, the ability to resist underground blasting shock waves is strong, it can be installed on the surface, and is also suitable for installation underground, especially suitable as the station fan of multi-stage station ventilation systems.
(6) It can reverse and reverse air, with a reverse air rate greater than 60%, and no need to build a reverse air duct.
(7) 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.
(8) The construction engineering volume is very small, and a large amount of investment can be saved.
(9) The noise is low.
K40 Mine Axial Flow Fan, Mine Ventilation Fan, Diffuser
When the K series mine energy-saving fans are used as the main fan and station fan, a dedicated diffuser should be equipped. When the surface main fan is equipped with a diffuser, it can convert some kinetic pressure into static pressure, reducing the loss of kinetic pressure at the outlet and achieving the purpose of energy saving. The fan installed underground is equipped with a diffuser, which can not only reduce the local resistance coefficient but also lower the kinetic pressure value at the diffuser outlet, thereby significantly reducing the local resistance of the fan installation and saving ventilation power consumption.
K40 Mine Axial Flow Fan, Mine Ventilation Fan, Start Control Box
Types of K series mine fan start control boxes: frequency conversion start control box, soft start control box, autotransformer voltage reduction type start control box. All come with forward and reverse rotation functions, meeting the ventilation requirements of mines.
