BDK65 mine fan

brief introduction
K series of mine energy saving fan, is the metallurgical industry mine energy conservation promotion station in the early 80s developed successfully. It has high aerodynamic efficiency, and good ventilation network, energy-saving effect is very significant and unique advantages; blade angle is adjustable, can reverse the anti wind operation, low noise; at the same time, the motor and the impeller direct coupled structure, good overall stability, convenient installation, safe and reliable, easy maintenance. Device local resistance is low; it is used as the main fan, civil engineering quantity of the device is very small, can invest a lot of energy; it is suitable to be installed in the underground, is the most ideal multistage fan station ventilation system of fan station machine.
Therefore, for more than a decade, K series of energy-saving fan has been widely used, making it the most important ventilation equipment in non coal mines. To date, more than and 600 national mine metallurgy, nonferrous metals, gold, building materials, chemical and nuclear industry system, the application of K series energy saving ventilator for mine. The Shanghai iron mine, Meishan Metallurgical Company Luzhong metallurgical mining company Zhangjiawa and Xiaoguanzhuang Iron Mine, Anshan Gongchangling underground mine, Wuhan Daye, Chengchao and Jinshandian Iron Mine, Jiuquan Steel Mirror of Tieshan iron mine, Hanxing Mine Bureau Yushiwa iron ore and West Shimen, Hubei Daye Non-Ferrous Metals Co of Daye Tonglushan Copper Mine, two mine Jinchuan Non-ferrous Metals Company, Liaoning Hongtoushan Copper and Wulong gold mine, Hebei copper mine and Jinchangyu Gold Deposit, Honghuagou gold deposit in Inner Mongolia, Shandong, Zhaoyuan, Sanshandao, Jiaojia and Xincheng Gold Mine and so on, the various systems of the large and medium-sized key mine main fan, auxiliary fan and fan, generally adopts K series energy saving ventilator for mine, achieved the ideal effect and economic benefits.
K series of mine energy saving fan includes JK, DJK series fan, DK40, DK45 series main fan and K40, K45 series main auxiliary fan. A new generation of K series energy saving fan is provided with a stabilizing ring device characteristic curve without hump, higher efficiency, better performance, more specifications, wide application range, large, medium and small types of non coal mines, can choose to apply the main fan, auxiliary fan, fan and fan stations at all levels fan.
Warmly welcome the units and all kinds of mines, selected by the metallurgical industry mine energy conservation station in the development, production by our factory K series of mine energy saving fan.
High efficiency and low noise
JK series mine local fan
JK series of mine local fan, energy saving and low noise (the fan), is designed according to the needs of metallurgy, nonferrous metals, gold, building materials and chemical industry, nuclear industry and other non coal mine local ventilation, suitable for all kinds of cross section of tunnel ventilation, mining field and the wind, the bottomless scraper sublevel mining method for road ventilation and other local ventilation and some auxiliary ventilation. It can also be used in tunnel construction, underground engineering construction, etc..
The design of the JK series of fan, taking into account the needs of various types of local ventilation exhaust dust exhaust air volume, air supply duct, commonly used specifications, wind resistance, and the use of the conditions of the mine. JK series fan is divided into single wheel JK 1 HP (see Figure 1), double wheel JK-2 No. (see Figure 2) and the DJK three rotary operation. The structure of the JK40 series fan (with front and rear silencer) is shown in Figure 3, DJK50 series of rotating fan (with front and rear silencer) structure see figure 4. The JK40 series fan and DJK50 series fan can be directly installed on the floor of the roadway, or can be hung on the wall or roof of the roadway.
JK series fan has the following characteristics:
(1) high operating efficiency. The maximum total pressure efficiency of single stage and double stage working wheels are 92% and 83% respectively, and the maximum total pressure efficiency of the rotary type is about 85%, which is higher than that of the original JF series fan by a factor of 20 to 30%.
(2) complete specifications, strong adaptability. There are various combinations of air volume and total pressure of the fan, the air supply distance is from 80 meters to 600 meters (the air supply distance can be up to more than 1200 meters), which can meet the different needs of users.
(3) small size, light weight, flexible and convenient to move. In the performance of the JF series with the same fan, the volume reduction of 20 to 30%, weight reduction of 20 ~ 30%.
(4) low noise. The noise of the air mine occasions measured 1 No..4 fan does not exceed 86dB (A). If the user has special requirements for the noise of the fan, we can complete the muffler.
JK series of fan motor are 2 poles, the speed of 2860 ~ 2930r/min.
The main technical parameters of JK series fan, see table 1.
