HTF series of high-temperature exhaust fan fire Overview: HTF series fire temperature exhaust fan with excellent performance, high temperature performance, high efficiency, covering less than the centrifugal fan, easy installation. HTF series fire temperature exhaust fan of "national fixed fire extinguishing systems and fire-resistant component quality inspection center" test qualified exhaust fan, its performance to the leading domestic level. High temperature performance: Fan Test conform GBJ45-82 Fire Code standards, established above the standards of corporate internal control assurance system can run continuously under high temperature 300 ℃ under the conditions of 60 minutes or more exhaust fan wucheng, 100 ℃ temperature conditions of continuous 20 hours / time is not damaged, it is widely used in the senior civil oven, underground garage, tunnels and other occasions. 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, the installation environment select 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, the fan and adjust the level of a solid 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. Two-speed exhaust fan in high-rise building fire smoke system for high-level basement usually work accident smoke exhaust state two-speed, two-speed asynchronous motor is particularly suitable. Two-speed fan running at high speed into a low-speed exhaust fan price, synchronous speed exhaust fan to improve the lot of the purchase, the amount of exhaust greatly improved accordingly, then the system immediately replaced by the exhaust smoke condition. But in the design process, will encounter Electric two-speed fan control problems, that is how to solve the motor windings from Δ-connected to a dual-Y-connected conversion and interlock, fire linkage automatic and manual control; fan at high speed and reliability of protection shutdown how to maximize safety incidents smoke, how to ensure that the power supply and other issues.
