Exhaust fan installed before 1, the wind turbine installation should be carefully examined before the fan is intact, each fastener bolt is loose or off, whether the collision impeller hood. Carefully check fan or blinds during transport without deformation by Loss. 2. Install selected environmental exhaust fan installed at the outlet, the outlet should be noted that the opposite can not have too much of an obstacle within 2.5 -3M. When the exhaust fan installation 1, the installation smoothly: the wind turbine installation should pay attention to the horizontal position of the fan exhaust fan maintenance, adjustment to the level of a solid fan and ground plane after installing the motor can not have tilt. 2, the fan should be installed so that the motor is in position adjustment bolts easy to operate. When adjusting belt tension for ease of use. 3. When installing the fan bracket, be sure to let stand firm and level ground plane, re-install reinforcement angle iron beside the fan if necessary. 4, the fan after installation, to check their tightness around. If the space available solar panels or glass glue for sealing. Fire exhaust fan set Location: Distance exhaust fan fire tunnel side walls should not be too close, so as not to affect the ventilation exhaust fan fire arrangement minimum distance from the wall of the tunnel 20 cm, rescue 'fixed' settings will tunnel into. Disaster different regions make full use of deviated and both ends of the tunnel exhaust fan fire rescue station designated as wind and smoke into the new channel, ventilation must be maintained at a positive pressure cross-channel port exhaust fan buy, to prevent smoke within the flow channel. ventilation system blows air from the accident 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 wait area needed fresh air. region according to different accident inside the tunnel using different disaster prevention ventilation. 'sentinel' Disaster ventilation program implementation point relief when the train, in the 'point' range of contact for all cross-channel set You can reverse the fan made from fresh wind tunnel safety product introduction;. 1.HTF type fire temperature exhaust axial fans, the basic form of an axial flow type structure, with high temperature motor, arranged a special motor cooling system, product by the National Fire Equipment Quality Supervision and Inspection Center GA211-1999 "fire exhaust fan high temperature test method" high-temperature test at medium temperature conditions of high temperature 300 ℃ continuous operation more than 60 minutes at a temperature of 100 ℃ continuous operation 20 h / time is not damaged exhaust fan, exhaust ventilation can be dual-use. 1.2 Categories by Mounting points: horizontal and Roof (W type). Press the air flow pressure point: there is pressure type Ⅰ and Ⅱ (double speed); medium-pressure (mixed flow impeller) has Ⅲ, Ⅳ type (double speed); there is low pressure type D1, D2 type. Press Speed ??points: single-speed, two-speed, variable frequency (by frequency conversion motor with variable frequency controller, inverter implementation, in order to adapt to different conditions, it is recommended to adjust the frequency locked in 25Hz ~ 50Hz). 1.3. To meet the noise requirements of different places, the fan can be equipped with different lengths muffler, it can be made into a sheathed (housing silencer). 2, HTF-type fire temperature exhaust axial fans working conditions Operating temperature: -20 ℃ ~ + 60 ℃ (continuous operation); temperature: 100 ℃ (continuous operation 20 hours), 300 ℃ (continuous operation 60 minutes ); 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 fans can be widely used application rise construction, oven, underground garage, tunnels and other places exhaust ventilation.
