Fire exhaust fan when voltage instability should be how to deal with it exhaust fan fire performance is outstanding, and has been widely used by the majority of users, and fire exhaust fan application is also relatively strong, voltage instability The case can also be applied exhaust fan fire low bid, but we have to operate it reasonable exhaust fan fire brand of choice, the only way to successfully complete exhaust tasks: We all know that fire is mainly used in the medium temperature exhaust fan at 100 ℃ after another 20 hours of work / time is not damaged, high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Exhaust fan fire main arguments in its operating temperature, wind, noise, total pressure, efficiency, electrical power, speed and shaft power. Fire exhaust fan use the time to pay attention to work under voltage stable power environment. Power resources in poor environments should add the appropriate circuit protection measures, so that the amount of damage can be prevented fire exhaust fan. Meanwhile fire exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust ventilation or, more than 60 minutes of continuous operation at 300 degrees Celsius temperature conditions, medium temperature for 20 hours at 100 degrees Celsius / second no damage, fire is the ideal necessary facilities. Hope that the majority of users in the use of fire exhaust fan, be sure to perform the correct operation of the above description, a friend who saw this Title are able to successfully complete operating exhaust fan fire exhaust fan fire work, its performance fully It uses. Distance from the tunnel exhaust fan fire should not be too close to the side wall, so as not to affect the ventilation. Fire exhaust fan arranged a minimum distance from the wall of the tunnel 20 cm, rescue "sentinel" setting will tunnel into different disaster prevention area, make full use of exhaust fan fire deviated and fixed at both ends of the tunnel as a rescue station into the fresh air and exhaust passages, ventilation must be maintained at a positive pressure cross-channel ports to prevent flue gas flow channel. The accident tunnel ventilation system blows air through the secure tunnel to cross-channel, cross-channel and suppress the flue gas into the accident did not occur authentic wholesale tunnel fire exhaust fan, meet evacuees facing fresh air into the tunnel cross passages and safety, at the same time waiting area needed to ensure the fresh air. According to different regions of the accident in the tunnel with different disaster prevention ventilation. "Sentinel" Disaster ventilation program implementation sentinel relief when the train set may be reversed in the "sentinel" range for all of the cross-channel fan made contact with fresh air from within the security tunnel. First exhaust fan fire from the side walls of the tunnel is not too close, to avoid affecting ventilation. The accident tunnel ventilation system blows air through the 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 the required waiting area Fresh air. Shaft and take full advantage of 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 ports to prevent flue gas flow channel. The main exhaust fan fire proper placement method is that, we must pay attention to the above description, the operation can be carried out smoothly in order to improve their effectiveness. Fire exhaust fan preferred brand, Shangluo fire exhaust fan, flat fiberglass pass by Wu Teng County 庄传平 fiberglass processing place. Wu County Teng 庄传平 FRP processing at (www.sdtengfei.com) strong, credible, Shandong Texas fan, ventilation equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead pass flat glass and steel into the brilliant and you work for a better future!
