110kw Mine Ventilation Fan K40-4-NO15 Mine Axial Flow Fan
K40-4-NO15 Mine Axial Flow Fan Q: 28.7 – 62.6 m³/s Pa: 387 – 1746 Impeller Diameter: 1500mm Blade Quantity: 8 Motor Frame Size: YE3-315S-4
The 110kw K40-4-NO15 Mine Axial Flow Fan is specially designed to meet the ventilation needs of various non-coal mines such as metallurgy, non-ferrous metals, gold, chemical industry, building materials and nuclear industry. It can be used as a main fan or auxiliary fan, and can be installed either on the surface or underground. It is suitable for multi-fan combined operation and is an ideal fan for each level of multi-fan series multi-level station ventilation systems. It is also applicable for ventilation and air exchange in large workshops, tunnels, civil air defense projects and other places.
2. Features of 110kw Mine Exhaust Fan K40-4-NO15 Mine Axial Flow Fan
(1) It adopts twisted wing-shaped blades, with high aerodynamic efficiency and extremely significant energy-saving effect.
(2) It has diverse performance and complete specifications, which can be well matched with various resistance and air volume types of ventilation networks, and can maintain long-term efficient operation.
(3) It is equipped with a steady flow ring device, and the characteristic curve has no hump. There is no risk of surging, and it can operate safely and stably under any resistance conditions, and is suitable for multi-fan combined operation.
(4) It adopts a direct connection structure between the motor and the impeller, with good overall stability, easy installation and maintenance, and low local resistance of the device. Compared with belt and long shaft transmission, it has higher transmission efficiency, no transmission faults, no risk of shaft breakage, and slight foundation settlement and sliding do not affect normal operation.
(5) It has a compact structure and good moisture-proof performance. The fan body is made of steel plates and steel sections welded together, and the blades are made of steel plates, hollow, with high blade and overall strength, strong resistance to underground explosion shock waves, and can be installed on the surface or underground, especially suitable for use as a station fan in a multi-stage ventilation system.
(6) It can reverse and reverse air, with a reverse air rate of more than 60%, and no need to build a reverse airway.
(7) The blade installation angle is adjustable, and the fan operating conditions can be adjusted at any time according to the changes in mine production.
(8) The civil engineering workload is small, which can save a lot of investment.
(9) The noise is relatively low.
3. Diffuser for 110kw Mine Exhaust Fan K40-4-NO15 Mine Axial Flow Fan
When the K and DK series of energy-saving mine fans are used as main fans and station fans, they should be equipped with special diffusers. When the surface main fan is equipped with a diffuser, part of the dynamic pressure can be converted into static pressure, reducing the dynamic pressure loss at the outlet to achieve the purpose of energy saving. When the underground fan is equipped with a diffuser, it can not only reduce the local resistance coefficient but also reduce the dynamic pressure value at the diffuser outlet, thereby significantly reducing the local resistance of the fan device and saving ventilation power consumption.
4. 110kw Mine Ventilation Fan K40-4-NO15 Mine Axial Flow Fan Starting Cabinet
