Main fan for Shandong DK40 counter-rotating mine

K series mine energy-saving fan was successfully developed in the metallurgical industry in the early 1980s. It has the unique advantages of high aerodynamic efficiency, which can be well matched with the ventilation network, and extremely significant power saving effects; and the blade installation angle can be adjusted, which can be reversed and reversed, and the running noise is low; meanwhile, the motor is directly connected to the impeller. Structure, good overall stability, convenient installation, safety and reliability, easy maintenance, and low installation resistance. As a main fan, its installation has a small amount of civil engineering and can save a large amount of energy. It is suitable for installation in underground and is multi-level The ideal station fan for the station ventilation system.

Therefore, for more than ten years, K series mine energy-saving fans have been widely used, making them the most important ventilation equipment in non-coal mines. As of now, more than 600 mines in the metallurgical, non-ferrous, gold, chemical, building materials and nuclear industries systems in the country have applied K-series energy-saving fans for mining. Among them, Shanghai Meishan Metallurgical Company Iron Mine, Luzhong Metallurgical Mining Company Zhangjiawa and Xiaoguanzhuang Iron Mine, Anshan Iron and Steel Gongchangling Underground Mine, WISCO Daye, Cheng Chao and Jinshandian Iron Mine, Jiugang Jingtieshan Iron Mine, Hanxing Mine Bureau Yushiwa and Xishimen Iron Mine, Hubei Daye Nonferrous Metal Company Tonglushan Copper Mine, Jinchuan Nonferrous Metal Company Second Mine, Liaoning Hongtuoshan Copper Mine and Wulong Gold Mine, Hebei Copper Mine and Gold Plant Gold Mine, Honghuagou Gold Mine in Inner Mongolia, Zhaoyuan, Sanshan Island, Jiaojia and Xincheng Gold Mine in Shandong, etc. The main fans, auxiliary fans and local fans of large and medium-sized key backbone mines in various systems are generally used in the K series Mine energy-saving fans have achieved ideal technical results and economic benefits.

K series mining energy-saving fans include JK, DJK series local fans, DK40, DK45 series main fans and K40, K45 series main and auxiliary fans. The new generation of K series of mine energy-saving fans is equipped with a stabilizing ring device, with no hump in the characteristic curve, higher efficiency, better performance, more specifications, and a wider range of application. It can select the applicable main fan, auxiliary fan, local fan and fan of each station.
