HTF (B) a fire temperature exhaust fan Francis, characteristics and application HTF (B) fire temperature exhaust mixed flow fan market models PYHL-14A fire exhaust fan, which uses multi-objective optimization design CAD software, matching molded wing twist Cone-shaped impeller, high temperature motor fully enclosed built, arranged a special motor cooling system. Use two-speed motor direct-drive, to one machine (that usually send row when high-temperature exhaust ventilation and firefighting), arranged after the electrical control box can be remotely controlled automatically. High temperature performance, air volume, high pressure, easy installation, etc., are widely used in high-rise buildings, drying room, underground garage, subway tunnels and other occasions to send fire smoke and exhaust ventilation. Press GA211-1999 Fire fan high temperature test methods, can run at 400 ℃ more than 100 minutes of continuous high temperature, medium temperature at 100 ℃ continuous operation 20 hours / time is not damaged, it has been approved for use by fire departments in major cities nationwide. HTF (B) Fire compact single-speed exhaust fan I type structure, saving installation space. Type II two-speed air inlet is provided in the current collector muffler, exhaust the fan at low speed operation, lower noise 1. comprehensive sample fan familiar Wuhu Wuhu pressure blower fans are familiar with the specifications of the form, the impeller rotation and airflow out direction and so on, before the wind turbine installation should be checked whether the collision phenomenon impeller, and conduct a comprehensive inspection of the components Wuhu Wuhu pressure blower, the attachment is complete, whether the firm connection of the components, carefully check whether the blades due to shipping damage or deformation before installation, or should be repaired. 2, the wind turbine should be coupled to a separate support import and export, plus the weight of the pipe is not allowed on the blower assembly, wind turbine installation should pay attention to the horizontal position of the fan, the fan and the foundation coupled combination of surface and out of the wind pipe It should be adjusted so that the natural fit, not be forced to join. 3, after the wind turbine installation, by hand or lever Stubbs impeller, check if there are too tight or collision, the availability interfere with the rotation of the article, no abnormal phenomenon, the only test run, the exposed parts of the wind opportunity gearing should protective cover (user-supplied). Such as the fan inlet pipe is not connected, but also need to purchase fencing or other safety devices (user-supplied). 4, the fan wiring must be correct and reliable, the fan housing should be properly grounded, grounding must be reliable. Fan power supply must be complete and meet the relevant requirements. Electrical wiring Electrical wiring must have professional knowledge. HTF series fire temperature exhaust fan for high-rise buildings, underground buildings and tunnels, drying room and other high-temperature exhaust or ventilation. Continuous operation at 280 ℃ under the high temperature for 30 minutes or more, the medium temperature at 100 ℃ continuous operation 20 hours / times without damage, fire is the ideal necessary facilities fire temperature exhaust fan performance options and Model Description 1 fan Performance Performance is listed in the table in the most efficient range of performance, according to the performance of the air volume is divided into five working points Wuhu Wuhu pressure blower, according to prevail in the selection of the performance table. Qualified fan factory is rated flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of the state performance standards are technical documents or ordering request shall prevail. 2, the wind turbine installation can be divided into horizontal and roof type, air volume, total pressure, dimensions and other properties have special requirements. HTF (XGF) series fire temperature exhaust fan is optimized design developed new products, it has high efficiency, flat curve characteristics conducive to energy conservation. The fan with direct drive motor Wuhu Wuhu pressure blower, according to different requirements of senior civil construction, the use of single-speed drive form, in order to achieve when ventilation temperature exhaust ventilation and firefighting purposes, widely used in high-level buildings, oven, underground garage, tunnels and other occasions.
