Product Name: Underground Mining Explosion Proof Exhaust Axial Flow Ventilation Fan Model NO.: FBD6.3/2x22 Certification: CSA, RoHS, UR, ISO, CE Mounting: Roof Fan Electric Current Type: AC Type: Axial Fan Blade Material: Stainless Steel Material: metal Trademark: JIUXING Transport Package: as Your Requirements Specification: Blade Angle: D1 Origin: China HS Code: 8530800000 Product Description Underground Mining Explosion Proof Exhaust Axial Flow Ventilation FanIntroduction ofFD Series Axial Flow Mine Ventilation FansFBD series mine rotating axial blower is mainly used in non-coal mine, for mine mining face of the long-distance ventilation. A new generation of versatile new energy-saving blower,AdvantagesWith a reasonable structure, complete specifications, high efficiency, energy-saving effect, low noise, air distance and other characteristics. Roadway length 2000m or less time to move the fan normal air supply, reducing the labor intensity, saving ventilation time, non-coal mine local ventilation is the ideal equipment.FBD series mine rotating axial blower is composed by two working hosts, two opposite directions by rotation of the impeller. Ie, a clockwise rotation of the impeller, the impeller rotates counterclockwise two, two leaf number relatively prime. An impeller to gain energy from the air by two impellers pressurized sent. Two impellers in addition to increasing energy flow, but also both the static ordinary axial fan vanes function to get oriented in the circumferential direction of the velocity components straightening at the same time, streamline the flow impact, increasing the flow of energy, reducing the wake vortex , reducing the noise.FBD series mine rotating axial blower using outsourcing double silencer, with low noise characteristics, constraints underground space for changing noise environment effect is remarkable.FBD series mine rotating axial blower body with steel plate welding structure, blade and chassis internal use corrosion proof treatment, so that the fan can run for long hours in a wet environment, effectively solve the other conditions caused by corrosion of the fan problem.FBD series of mine rotating axial supporting local fan motor is Y series three-phase asynchronous motor, the voltage rating of 380V. Fans can be set without stopping the machine plus drain devices to ensure the fan in operation for injection drain to ensure the long-term electrical reliability in harsh environments safe operation.FBD series mine rotating axial blower gas ambient temperature -20 ºC ~ +40 ºC, relative humidity less than 95% (25 ºC when), should not exceed 1000m altitude environment. Fan transmission medium dust content shall not exceed 200mg/m3. Fan main conveying air and non-corrosive not spontaneous, non-sticky material medium, dust content shall not exceed 200mg/m3.TechnologyParameterof FBD Series Axial Flow Mine Ventilation FansPhotos ofFBD Series Axial Flow Mine Ventilation Fans
