Fire temperature exhaust fan, both for the variety of building fire smoke htfc exhaust fan, but also for a variety of construction, civil air defense projects, underground railways, mines, tunnels and other smoke and exhaust. Other notes temperature of the fan motor is designed with special cooling systems. Main duct medium temperature 280 ℃, it can run more than 30 minutes continuously. ≤150 ℃ when long-term continuous operation. 1. The small size and lightweight light with the same amount of wind centrifugal fan less two-thirds of the space. Reduce the weight more than half. 2. Simple structure The fan consists of five main parts. ① ② impeller motor cycle air cooling system ③ ④ guide vanes, inner tube ⑤ outer cylinder. Disassembly and easy maintenance. 3. easy to install the fan according to the requirements of building construction with horizontal and vertical hanging installation. Three-phase 380V power supply Axial exhaust fan, 50HZ fire exhaust fan set Location: distance from the tunnel exhaust fan fire should not be too close to the edge of the wall, so as not to affect the ventilation exhaust fan fire arranged a minimum distance from the tunnel wall 20. cm, rescue "sentinel" setting the tunnel is divided into different regions of disaster prevention, fire exhaust fan full advantage of both ends of the inclined shaft and tunnel rescue station designated as the wind and smoke into the new channel exhaust fan, ventilation must be maintained cross-channel port is positive pressure to prevent flue gas flow channel. ventilation system blowing from the direction of the accident tunnel through a secure tunnel to cross the channel, inhibiting the flue gas into a cross-channel and tunnel accident occurred two-speed exhaust fan meet Evacuees facing fresh air into the tunnel cross passages and safety, while ensuring that the region needed to wait for fresh air in the tunnel area according to different accident ventilation Disaster different way. "sentinel" When the train disaster prevention program implemented sentinel ventilation When the rescue, settings can be reversed in the "sentinel" range for all of the cross-channel contact fans get fresh air from within the security tunnel fire temperature exhaust fan |.
