Mine fan is an axial fan Y9-26 boiler fans, because the use of the special nature of the industry and the applicable sites, and large differences in performance parameters and dimensions with the general axial-flow ventilation, so separate out go do a class. Classification and main mine fan model divided according to whether the explosion-proof type and general type Y5-48 boiler fans, explosion-proof models generally BK, BDK, FBCZ, FBCD, FBD, FBCDZ other common type of general models K, JK, DJK so on. By product structure is generally divided into ordinary type and rotary type Y8-39 boiler fans, common single leaf, common models k40, k45, jk40, jk58-1, jk56-1 etc., rotating type is divided into two kinds, one is a two-wheel double boiler fan motors, such as djk50, FBD type, the other is a twin impeller single motor, such as jk58-2, jk56-2 so on. Common K, DK Series About a fan of mine, a new generation of energy-K series fan of mine, mainly used for metal surface or underground mines shots fan, auxiliary fan ventilation, ventilation can be used for other occasions. 2, the main properties of the series of energy-saving fan, technical indicators are as follows: (1) series machine number: №7 ~ №26; (2) Series speed: 1450,980,730 r / min; (3) the amount of wind range: 2.0 ~ 164.2m3 / s; (4) the full voltage range: 38 ~ 3819pa; (5) Power range: 1.1 ~ 500kW; (6) the fan efficiency: K-type single-stage total pressure efficiency η = 94%, DK-type rotating hydrostatic efficiency η = 86%; (7) operating noise: LA≤85dB (A).
