Products; 1.HTF type fire temperature exhaust axial fans, its basic structure in the form of two-speed axial-flow exhaust fan fire price, with high temperature motor, arranged a special motor cooling systems, products, equipment, supervision by the National Fire Quality Inspection Center by GA211-1999 "high-temperature exhaust fan fire test method" high-temperature test, at medium temperature 300 ℃ high temperature over 60 minutes of continuous operation, 100 ℃ temperature conditions under continuous operation 20 hours / times without damage, dual exhaust ventilation can. 1.2 Installation divided by Product Category: Horizontal and roof type (W type). Divided by the amount of wind pressure: atmospheric model have type Ⅰ, Ⅱ (double speed); medium-pressure (for mixed flow impeller) has Ⅲ, Ⅳ type (double speed); there is low pressure type D1, D2 type. By the governor points: single-speed, two-speed, frequency (frequency conversion motor with inverter controller, the implementation of frequency control, in order to adapt to different conditions, it is recommended to adjust the frequency locked in 25Hz ~ 50Hz). 1.3. In order to meet the requirements of different places noise exhaust fan, fan can be equipped with different lengths muffler, can also be made sheathed (housing silencer). 2, HTF-type fire temperature exhaust axial fans working conditions Operating temperature: -20 ℃ ~ + 60 ℃ (continuous operation); temperature: 100 ℃ (20 hours of continuous operation), 300 ℃ (60 minutes of continuous operation ); temperature: <90%; medium conditions: air (dust content of no more than 100mg / m3); Power supply: three-phase, 380V / 50Hz; 3, HTF-type fire temperature exhaust fan axial fan applications can be widely used rise construction, oven, underground garage, tunnels and other places smoke ventilation. 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 Fire exhaust fan to prevent smoke airflow ventilation system to supply air to the incident direction of the channel tunnel from a secure tunnel through the cross-channel, cross-channel and suppress smoke into the tunnel accident during the two-speed exhaust fan fire, meet evacuees facing the new air into the cross-channel and within a secure tunnel, while ensuring that the region needed to wait for the fresh air. According to different regions of the accident in the tunnel with different ventilation mode Disaster. "sentinel" Disaster ventilation scheme implemented sentinel relief when the train when, in the "sentinel" range All contact cross channel settings can be reversed to obtain fresh wind from the fan inside the secure tunnel Axial exhaust fan |.
