Features: Francis impeller hub, high temperature motor, motor fully enclosed built, wide Degas pressure blower, and a special motor cooling system, excellent high temperature performance, high efficiency, low noise, reasonable structure, small size, easy installation, etc. Advantages 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 designated units, Tongling pressure blower manufacturers, the main products are modular air conditioning units, VAV cabinet air conditioning units, fan coil units, fire dampers, smoke valve, multi-leaf smoke vents, 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 detection center in China Fire product information online. Price concessions, the full range, now for many domestic manufacturers OEM OEM services, has maintained a good partnership in the country with more than 1,000 distribution services, good quality and good after-sales service, sincerely look forward to your cooperation. . Before installation should be carefully checked before installation whether the blades and chassis have damaged or deformed due to the transport, Hefei pressure blower role, or should be restored. 2. Check for loose bolts, fan before the start, we should first check within Shaanxi two-speed exhaust fan duct interfere with or without rotation of items. 3. Check the motor insulation performance is good, after turning on the power to check friction collision and abnormal vibration. The reason a lot of fan vibration, two-speed exhaust fan Shandong Asia were from the following areas to check: a, impeller and duct with friction, and audible and vibration abnormality; b, foot into bolts not strong, also large vibration occurs; connecting bolts c, impeller and sleeve loose; d, bracket and motor connection loose bolts cause impeller unbalance, bearing damage caused by excessive vibration. 5. Under normal operation found that the motor temperature is too high, Shaanxi two-speed exhaust fan may be caused by the following reasons: a, motor bearing damage, Fuyang pressure blower roof, with a small gap, does not meet the requirements; b, the shaft and bearing installation tilt, bearing two different axes; c, three-phase power supply voltage is too low or run-off phase. 6. The exhaust port in Shandong Pacific two-speed exhaust fan should be set up interlock device, when any one of the exhaust port open, exhaust fan that is able to automatically start. Texas Pacific Group is a collection of central air-conditioning and refrigeration end, fire ventilation equipment, glass steel products, such as several major products in the research, design, development, production, sales and installation in one of the modern large enterprise groups. All products are at the lowest price in the hot, welcome you to contact us, we will warm service and the best quality of products and services to everyone! Exhaust fan impeller is made of steel wheels hydraulic stretch forming exhaust fan Price, hydroforming press the blade exhaust fan blades and hub assembly welding forming. Technology Second, the HTF fire exhaust fan impeller static and dynamic balance correction exhaust fan installed, balance accuracy is not greater than G5.6 levels. Process Third, and finally we would also like to learn about the production process is HTF fire exhaust fan is spinning from the outer cylinder flange XGF fire temperature exhaust fan -HTF (B) series fire temperature exhaust is with the overall flanging Francis fan smoke multi-objective optimization using CAD software design, matching molded twisted wing Francis impeller, totally enclosed motor built supply temperature exhaust fan, arranged a special motor cooling system. Use two-speed motor direct-drive, to one machine (that usually send exhaust ventilation and fire when using high-temperature exhaust), arranged after the electrical control box can be remotely controlled automatic pressure blower swf Chaohu, Hefei fan factory outlets, wide Degas pressure blower fan by Shandong Air Conditioning Equipment Co.
