FBCDZ series anti-explosion main mine fan
The FBCZ, FBCDZ and FBD series fans manufactured by the Company have the following characteristics in the aspects of structure and various performances:
2.1 The fans of various series all use the simplest transmission device of the direct connection between motor and impeller.
2.2. Wing twisted blades are used, which have high aerodynamic efficiency. The static pressure efficiency of single-stage series fan and counter-rotating series fan devices is as high as above 80%, thus the high efficiency area is wide and energy saving effect is obvious.
produced with cylinder wall, and then accident is caused, and make the operation of fans be safer and more reliable.
2.3 Fans for mines select explosion-proof motors and put motors in isolating chambers of fans to ensure the isolation between wind current and air flow containing gas in fan flow channel and meanwhile, play heat dissipation and diversion function. The wind current pipe makes the surrounding area of motor is connected with atmosphere, which both increases the safety performance of motor and directly dissipate the heat of motor to air and improve the safety of fan operation.
2.4 In the cylinders of rotating parts of impellers of fans for mines, copper ring devices for inhibiting spark energy are added to prevent deformation from being occurred during high speed running of impellers and spark from being
2.5 There are various performances and complete specifications in the Company. The fans matching with ventilation networks of various coal mines and non-coal mines are available for selection, and long-term high efficient operation could be guaranteed.
2.6 Fans could reverse the air flow and the reversal air flow could reach more than 60% of direct air flow. Thus the “S” type air channel, reversal air channel and fan room of traditional air cave outlet could be saved. The fans are especially suitable for places with small site area, surface subsidence and landslide dangers.
