Exhaust fan for the selection of the main control parameters dtf temperature exhaust fan, air volume, total pressure htf exhaust fan Francis fan SWF Huaibei Chaohu, efficiency, noise, electrical power, speed and shaft power. 2. The exhaust fan at a temperature not higher than 85 ℃ conditions should be long-term normal operation. 3. The exhaust fan should ensure that: When the transmission medium at a temperature of 280 ℃ continuous work 30min, and still continuously at medium temperature cooling to ambient temperature during normal operation. HTF Fire fan performance properties listed in the table is the most efficient performance within range, according to the air volume is divided into five performance points, according to prevail in the selection of the performance table. Factory fire fans quality products is rated flow, total pressure error does not exceed ± 5%, the performance of the selection list is performance under standard conditions, regardless of technical documents Features: Francis wheel impeller, high temperature motor, motor fully enclosed built, and a special motor cooling system, high temperature performance, high efficiency, low noise, reasonable structure, small size, easy installation, etc., installed on horizontal, vertical, lifting can be. Applications: building, drying room, underground garage, subways, tunnels and other fire sent smoke and exhaust ventilation, low speed for two-speed fan usually through ventilation, fire smoke at high speed for the Jingjiang City in the air-conditioning Equipment Co. central air terminal equipment and fire ventilation exhaust of professional equipment manufacturers, fire products sentinel units, the main products are modular air conditioning units, VAV cabinet air conditioning units, fan coil units, fire dampers, exhaust valves, multi-leaf smoke Huaibei mouth Chaohu SWF Francis fan, pressure delivery outlet, leafy exhaust port, positive pressure blower, fire temperature exhaust fan fire ventilation and other products, the Department of air conditioning all fire products are all qualified through the National Fire Testing Center, fire in China product information online. Price concessions, the full range, now for many domestic manufacturers OEM OEM services, has maintained a good cooperative partnership Huaibei Chaohu SWF Francis fan, in the country with more than 1,000 distribution services, good quality and good after-sales service Huaibei Chaohu SWF Francis fan, sincerely look forward to working with you. 1, fully conversant with the sample fan, fan familiar with the specifications, form, impeller rotation direction and the direction of airflow in and out, etc., before the wind turbine installation should be checked whether the collision phenomenon impeller, and conduct a comprehensive inspection of the components, the attachment is complete, each whether the coupling member firm, before installation carefully check whether the blades due to shipping damage or deformation, or should be restored. 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.
