Henan main fan blower K40, K40 main fan blower, fan supplied by Zibo Zibo Ming-Bo fan. Zibo Ming-Bo Fan Co. (www.zibofan.com) Shandong Zibo quality certified company Commercial Union, with fans and other brands, has a good reputation, honesty, service-oriented "business alliance Service" icon on the page, we will be happy to serve you! K40 fan use and maintenance (1) from the fan inlet direction, impeller should be rotated counter-clockwise. (2) each mounted on the impeller blade angle must be consistent. When you need to adjust the angle of the blade is installed, you can remove the hub cap open, loose leaf blower sturdy nut K40 main fan, the blades are adjusted to the desired mounting angle, and then the nut rugged good. In order to facilitate the next adjustment nut should be rubbed in a strong layer of grease. Should be particularly noted that the angle of the blades installed after transfer large fan input power, must be adapted to the motor with a rated power to prevent motor overload. Fans K40 K40 K40 mine fan main fan blower K40 K40 K40 energy-saving fan of mine main fan blower K40 K40 YB series of energy-saving fans supporting derived YBFe series flameproof three phase asynchronous motors, the motor is mounted on the outside and has a fully enclosed certain compressive strength of dense heat shield, and pressure balance pipe, the motor is always in the air without gas being run, reaching the mine explosion regulations concerning requirements. BK54 series of single-stage work round structure, fan and diffuser vanes intermediate settings to improve static efficiency. The aircraft impeller for maximum efficiency of 0.93, the highest total pressure efficiency of the entire system is 0.82 K40 main fan blower device static efficiency is 0.75. Thus, higher efficiency, energy-saving effect is remarkable, in parallel using multiple local fan ventilation than the currently used aircraft, that bureau bureau on behalf of the owner or group of ventilation can save 60-80%. The machine can reverse the anti-wind, the anti-wind of up to 65% -85% positive air flow. Need for a separate anti-air channel, has anti-saving infrastructure investment and wind speed advantages.
