Practical application of mine fan in mine tunnel
Shandong Haihua Environmental Protection Equipment Co., Ltd. mainly produces mine main fans, air suspension fans, sewage treatment fans, roots fans, high-pressure centrifugal fans, anti-corrosion fans, explosion-proof fans and other types of fans
The main fan for mine is mainly used for ventilation of the main and auxiliary fans on the ground or underground of metal mines. It can also be used for other ventilation and ventilation occasions.
2. The main performance and technical indicators of this series of energy-saving fans are as follows: (1) Series machine number: №7 ～ №26; (2) Series speed: 1450, 980, 730 r / min; (3) Air volume range: 2.0 ～ 164.2m3 / s; (4) full pressure range: 38 ～ 3819pa; (5) power range: 1.1 ～ 500kW; (6) fan efficiency: K type single stage full pressure efficiency η = 94%, DK type counter-rotating static pressure Efficiency η = 86%; (7) Operating noise: LA≤85dB (A).
3. This product is composed of DK40, DK45, K40, K45 and other energy-saving fans for mining. K40, K45 series auxiliary fans use the simplest transmission structure of the motor and impeller directly connected, and are composed of current collector, main body and diffuser. . It adopts new high-efficiency airfoil-shaped twisted blades, the installation angle can be adjusted, and the stabilizing ring device is installed to make the aerodynamic performance curve without hump. The base can be equipped with wheels that move axially. Therefore, it has the advantages of high efficiency and low noise, high efficiency area, stable performance, simple structure, easy installation, and convenient use. The main fans of DK40 and DK45 series adopt two sets of K40 and K45 fans of the same model and same power. The two-stage impellers rotate in opposite directions to each other, forming a counter-rotating structure. Compared with the long-shaft transmission type main fan, they have the advantages of high operating efficiency, low operating bureau resistance, saving civil construction investment, etc., and have significant energy saving effects.
