Installation and Use: 1) can be vertical, horizontal and hanger installation. Fan base must naturally be combined with basal plane, and not to beat coupling force base, the weight of the pipe shall be applied to the turbine components. 2) should be carefully checked before installation whether the impeller and casing damage and deformation due to transport exhaust fan manufacturer, if any, should be repaired before installation. 3) Check for loose coupling bolts high temperature exhaust fan fire, electrical insulation is good htf exhaust fan, whether or interfere with the rotation of objects within the fan duct. 4) To install the fan after commissioning, abnormal rub, touch, and vibration to be excluded immediately. Fire exhaust fan set Location: Distance tunnel fire exhaust fan should not be too close to the side wall, so as not to affect the ventilation exhaust fan fire tunnel wall arranged for a minimum distance from 20 cm, rescue "sentinel" setting will tunnel into. Disaster different regions, make full use of deviated and both ends of the tunnel exhaust fan fire rescue station designated as the wind and smoke into the new channel, cross ventilation openings must maintain positive pressure state exhaust fan to prevent flue gas flow the channel. ventilation system blowing from the direction of the incident tunnel through a secure tunnel to cross the channel, inhibiting the flue gas into a cross-channel and tunnel accident did not occur to meet the evacuees facing fresh air into the tunnel cross passages and safety, while ensuring that waiting area needed fresh air in the tunnel area in accordance with the different accident Disaster different ventilation mode. "sentinel" Disaster ventilation scheme implemented when the train rescue point in the "sentinel" range for all of the cross-channel settings can be contacted Reverse fans get fresh air from within the security tunnel.
