GYF fire temperature exhaust axial fans Overview; 1. Purpose: GYF fire temperature exhaust axial fans tested in accordance with GB50045 ~ 95 "fire protection design of tall buildings" and GB50067-97 "garage, repair garage, parking lot design fire protection ", is a new energy-efficient exhaust fan fire. The fan can be used as various buildings dedicated fire smoke, but also for high-rise buildings, general building, underground garage, culverts and other mines and exhaust smoke exhaust fans, such as underground repository for ventilation usually change gas, turn with winds of smoke when needed. 2. Structure: airfoil axial flow type: There GYF-I (single speed) and GYF-SI (double speed); two kinds of fire exhaust fan. Leaf type with diagonal flow: There GYF-II (single speed) and GYF-S2 (double speed) of two fire exhaust fan. If users have higher requirements on noise, can be made GYF-BX silencer exhaust fan fire. Fans can also be made vertical, mounted on the roof to do with fire smoke. GYF fire temperature exhaust fan consists of five main components: (1) the impeller (2) motor (3) within the circulating air impeller (4) guide vanes, the inner cylinder, guide hole (5) of the outer cylinder. Fire exhaust fan set Location: Distance tunnel fire exhaust fan should not be too close to the side wall exhaust fan manufacturers, to avoid affecting the ventilation exhaust fan fire tunnel wall arranged for a minimum distance from 20 cm, rescue "sentinel" of. Set the tunnel disaster prevention into different regions, make full use of fire exhaust fan deviated and fixed at both ends of the tunnel as a rescue station into fresh air and exhaust channels, cross ventilation openings must maintain positive pressure state, to prevent smoke flow into the channel. ventilation system to supply air to the incident direction from a secure tunnel through the tunnel cross-channel htf exhaust fan, inhibit the flue gas into a cross-channel and tunnel accident did not occur to meet the evacuees facing the new air into the tunnel cross passages and safety inside, waiting area while ensuring the required fresh air in the tunnel area according to different accident Disaster different ventilation mode. When the "sentinel" Disaster ventilation scheme implemented when the train designated rescue, all in "sentinel" range Contact cross channel settings can be reversed to obtain fresh wind from the fan inside the secure tunnel.
