Main ventilation fan for Coal Mine No. 20 in Jiangxi
Main uses and application scope
The explosion-proof axial-flow main ventilation fan for mining applications is a highly efficient and energy-saving forced mechanical ventilation device specially designed for various coal mines, mines, and tunnels. It typically adopts an exhaust-type ventilation configuration. This series of fans is custom-designed based on the ventilation network parameters specific to coal mine shafts and features an adjustable blade installation angle. By promptly adjusting the blade installation angle in response to changes in the operating conditions of the mine’s ventilation network, the fan can consistently maintain high efficiency and energy savings. Moreover, this fan employs an integrated structure with the motor directly coupled to the impeller, offering numerous advantages such as high efficiency, energy conservation, low noise, and simple installation and disassembly. This ventilation fan is also suitable for metal mines, chemical mines, and other industrial facilities that require forced ventilation.
Model and Meaning
The performance curves provided by the fan were all obtained through actual simulation experiments conducted using a standard duct network, with gas temperature t = 20℃ and gas density p = 1.2 kg/m³. 3 It is plotted based on the standard conditions where atmospheric pressure P = 101,325 Pa.
Model Definition Explanation: FBCDZN o Take 28/2x400 as an example: F—fan; B—explosion-proof; C—withdrawal type; D—counter-rotating; Z—main ventilation; N o 28—Machine number, expressed in decimeters of the impeller diameter; 2x400—Installed power, where “2” indicates two electric motors and “400 kW” represents the power in kilowatts.
