1, a new generation of K series of mine energy-saving ventilators, mainly used in metal mines on the ground or underground fan, auxiliary fan ventilation, can also be used in other ventilation and ventilation occasions.
2, the series of energy-saving fan main performance, technical indicators 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 to spin static pressure efficiency η=86%; (7) Operating noise: la≤85db (A).
3, the product by DK40, DK45, K40, K45 and other mining energy-saving fan composition, K40, K45 series auxiliary fan using the motor and impeller direct connection of the simplest transmission structure, by the collector, the main body and diffuser and other components. Using a new type of high efficiency wing twisted blades, the mounting angle is adjustable, and the stable flow ring device is provided to make the aerodynamic performance curve without hump, and the base can be fitted with axial moving wheels. Therefore, it has the advantages of high efficiency, low noise, wide efficiency zone, stable performance, simple structure, easy installation and convenient use. DK40, DK45 series main fan using the same model, the same power of 2 K40, K45 type fan docking together, two-stage impeller mutual rotation, constitute the spin structure.
Compared with the long axle drive type main fan, they have the advantages of high operating efficiency, low Operation Bureau, saving civil investment and so on, and have remarkable energy-saving effect.
