90kw mine ventilator K45-4-NO13Auxiliary Fan for Mine Q:.19.2-36.3m³/s Pa: 431-827 Fan blade diameter: 1300mm Number of blades: 8 Motor base size: YE3-225M-4
1. 90kw Mine Ventilator K45-4-NO13Mine Auxiliary Fan Application
The 90kw mine ventilator K45-4-NO13 mine auxiliary fan is specifically designed to meet the ventilation needs of various non-mine industries such as metallurgy, mining, gold, chemical industry, building materials, and nuclear industry. It can be used as either the main fan or the 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 for each station in the multi-fan series multi-stage station ventilation system. It is also applicable for ventilation and air exchange in large workshops, tunnels, and civil defense projects, etc.

Features:
(1) Adopting twisted airfoil blades, it has high aerodynamic efficiency and remarkable energy-saving effect.
(2) It has diverse performance and complete specifications, which can well match various types of resistance and air volume ventilation networks, ensuring long-term efficient operation.
(3) Equipped with a constant flow ring device, 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 joint operation.
(4) Adopting a direct connection structure between the motor and the impeller, it has good overall stability, convenient installation, easy maintenance, and low local resistance. It has higher transmission efficiency than belt and long shaft transmission, without transmission faults, no shaft breakage danger, and slight foundation subsidence and slippage do not affect normal operation.
(5) Compact structure, 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, with high strength of the blades and the overall structure, strong resistance to underground blasting shock waves, which can be installed on the surface or in the underground, especially suitable as the station fan of multi-stage station ventilation system.
(6) Reversible reverse ventilation, reverse ventilation rate greater than 60%, no need to build reverse ventilation duct.
(7) The blade installation angle can be adjusted, which can adjust the fan operating conditions according to the changes in mine production.
(8) The amount of civil engineering work is very small, which can save a lot of investment.
(9) Low noise.

When the K, DK series mine energy-saving fans are used as the main fan and station fan, they should be equipped with special diffusers. The main fan installed on the surface should be equipped with a diffuser to convert part of the kinetic pressure into static pressure, reducing the loss of the outlet kinetic pressure, in order to achieve energy-saving purposes. The fan installed underground should be equipped with a diffuser, which can not only reduce the local resistance coefficient but also reduce the outlet kinetic pressure value of the diffuser, thereby significantly reducing the local resistance of the fan device and saving ventilation power consumption.
